What is the painful condition called shingles? | CNN



CNN
 — 

Sen. Dianne Feinstein, the 89-year-old California Democrat, recently announced she is out of the hospital and recovering at home from shingles, a painful viral inflammation in the skin’s nerves that causes a blistering rash lasting for two to four weeks. Feinstein was diagnosed in February and hospitalized in San Francisco last week.

Shingles, also called herpes zoster, is caused by the varicella-zoster virus — which is the same virus responsible for chickenpox. Varicella zoster is also responsible for a rare condition called Ramsay Hunt syndrome that caused pop star Justin Bieber’s face to become partially paralyzed in June 2022.

“As you can see, this eye is not blinking. I can’t smile on this side of my face. This nostril will not move,” Bieber said at the time in answer to fans who wondered why he had canceled performances.

Painful skin is one of first signs of shingles, and for some people, the pain is intense. It can create a burning sensation, or the skin can tingle or be sensitive to touch, according to the Mayo Clinic. Shingles can occur at other places on the body, such as the face and scalp, but the most common presentation is on the torso on one side of the body.

A red rash will begin to develop at the site of the pain within a few days. The rash often begins as a small, painful patch, which then spreads like “a stripe of blisters that wraps around either the left or right side of the torso,” the Mayo Clinic said.

In rare cases, the rash may become more widespread and look similar to a chickenpox rash, typically in people with weakened immune systems, according to the US Centers of Disease Control and Prevention.

In addition to pain, some people may develop chills, fatigue, fever, headache, upset stomach and sensitivity to light. See a doctor if you are over 50, have a weakened immune system, the rash is widespread and painful, or the pain and rash occur near an eye.

“If left untreated, this infection may lead to permanent eye damage,” according to the Mayo Clinic.

The varicella-zoster virus is highly contagious when in the blister stage, spreading through direct contact with the fluid from blisters and via viral particles in the air.

However, you cannot get shingles from someone who has shingles. If you aren’t vaccinated for chickenpox or haven’t previously had it and are infected by that person, you will develop chickenpox, which then puts you at risk for shingles later in life, the CDC said.

If you have shingles, you can prevent the spread of the virus by covering the rash and not touching or scratching the raised vesicles that form the rash, the CDC stated. Wash your hands often.

“People with shingles cannot spread the virus before their rash blisters appear or after the rash crusts,” the CDC said.

If the rash is covered, the risk of transmission “is low,” the CDC said. “People with chickenpox are more likely to spread (the virus) than people with shingles.”

If you think you have shingles, call a doctor as soon as you can, the CDC recommended. If caught early, there are antiviral medications, including acyclovir, valacyclovir and famciclovir, that can shorten the length and severity of the illness.

“These medicines are most effective if you start taking them as soon as possible after the rash appears,” the CDC said.

Doctors may also suggest over-the-counter or prescription pain medication for the burning and pain, while calamine lotion, wet compresses and oatmeal baths may ease itching.

For older adults, the population most likely to develop shingles, the best treatment is prevention. The US Food and Drug Administration approved a two-dose vaccine called Shingrix in 2017 for people 50 and older.

“Shingrix is also recommended for adults 19 years and older who have weakened immune systems because of disease or therapy,” the CDC said.

Shingrix, which is not based on a live virus, is more than 90% effective in encouraging the aging immune system to recognize and be ready to fight the virus, according to its manufacturer, GlaxoSmithKline.

Anyone who has had a severe allergic reaction to a dose of Shingrix or is allergic to any of the components of the vaccine should avoid it, the CDC said.

“People who currently have shingles, and women who are pregnant or breastfeeding, should wait to get Shingrix,” the CDC said.

Another vaccine called Zostavax, which the FDA approved for people over 50 in 2006, is 51% effective in preventing shingles, according to the CDC. Zostavax is based on a live virus, the same approach used for the chickenpox vaccine recommended in childhood. It has not been sold in the United States since November 2020.

If you have never had chickenpox, you can’t get shingles. However, once you’ve had chickenpox, the virus remains inactive in the spine’s sensory neurons, possibly erupting years later as shingles.

Two doses of a chickenpox vaccine for children, teens and adults, introduced in 1995, is 100% effective at preventing a severe case of chickenpox, according to the CDC. Immunity lasts 10 to 20 years, the CDC noted.

In the small number of people who still get chickenpox after vaccination, the illness is typically milder, with few or no blisters.

The CDC recommends the vaccine be given to children in two doses, the first between 12 and 15 months and a second one between 4 and 6 years. Anyone 13 years old and older who has no evidence of immunity can get two doses four to eight weeks apart, the CDC said.

Some people should not get the vaccine, including pregnant women, people with certain blood disorders or those on prolonged immunosuppressive therapy, and those with a moderate or severe illness, among others.

About 1 in 10 people will develop a painful and possibly debilitating condition called postherpetic neuralgia, or long-term nerve pain. All other signs of the rash can be gone, but the area is extremely painful to touch. Less often, itching or numbness can occur.

The condition rarely affects people under 40, the CDC said. Older adults are most likely to have more severe pain that lasts longer than a younger person with shingles. For some, the nerve pain can be devastating.

“Five years later, I still take prescription medication for pain,” said a 63-year-old harpist who shared his story on the CDC website. “My shingles rash quickly developed into open, oozing sores that in only a few days required me to be hospitalized.

“I could not eat, sleep, or perform even the most minor tasks. It was totally debilitating. The pain still limits my activity levels to this day,” said the musician, who has been unable to continue playing the harp due to pain.

Up to 20,000 people who attended a religious gathering may have been exposed to measles. What should they do next? | CNN



CNN
 — 

Up to 20,000 people who attended a religious gathering at a college in Wilmore, Kentucky, in February could have been exposed to a person later diagnosed with measles.

On Friday, the US Centers for Disease Control and Prevention issued an alert to clinicians and public health officials about the confirmed case of measles in an individual present at the gathering who had not been vaccinated against the disease.

“If you attended the Asbury University gathering on February 17 or 18 and you are unvaccinated or not fully vaccinated against measles, you should quarantine for 21 days after your last exposure and monitor yourself for symptoms of measles so that you do not spread measles to others,” according to the CDC advisory.

The CDC also recommended that people who are unvaccinated receive the measles, mumps, and rubella (MMR) vaccine.

Reading this news, people may have questions about measles, including its symptoms, infection outcomes and who is most at risk. They may also want to know what makes measles so contagious, what has been the cause of recent outbreaks and how effective the MMR vaccine is.

To help answer these questions, I spoke with CNN Medical Analyst Dr. Leana Wen, an emergency physician and professor of health policy and management at the George Washington University Milken Institute School of Public Health. Previously, she served as Baltimore’s health commissioner, where her duties included overseeing the city’s immunization and infectious disease investigations.

CNN: What is measles, and what are the symptoms?

Dr. Leana Wen: Measles is an extremely contagious illness that’s caused by the measles virus. Despite many public health advances, including the development of the MMR vaccine, it remains a major cause of death among children globally.

The measles virus is transmitted via droplets from the nose, mouth or throat of infected individuals. If someone is infected and coughs or sneezes, droplets can land on you and infect you. These droplets can land on surfaces, and if you touch the surface and then touch your nose or mouth, that could infect you, too.

Symptoms usually appear 10 to 12 days after infection. They include a high fever, runny nose, conjunctivitis (pink eye) and small, painless white spots on the inside of the mouth. A few days after these symptoms begin, many individuals develop a characteristic rash — flat red spots that generally start on the face and then spread downward over the neck, trunk, arms, legs and feet. The spots can become joined together as they spread and can be accompanied by a high fever.

A nurse gives a woman a measles, mumps and rubella virus vaccin at the Utah County Health Department on April 29, 2019 in Provo, Utah.

CNN: What are outcomes of measles infections? Who is most at risk?

Wen: Many individuals recover without incident. Others, however, can develop severe complications.

One in five unvaccinated people with measles are hospitalized, according to the CDC. As many as 1 out of every 20 children with measles will get pneumonia; about 1 in 1,000 who get measles can develop encephalitis, a swelling of the brain that can lead to seizures and leave the child with lasting disabilities. And nearly 1 to 3 out of every 1,000 children who are infected with measles will die.

Measles is not only a concern for children. It can also cause premature births in pregnant women who contract it. Immunocompromised people, such as cancer patients and those infected with HIV, are also at increased risk.

CNN: What makes measles so contagious?

Wen: Measles is one of the most contagious diseases in the world — up to 90% of the unvaccinated people who come into contact with a contagious individual will also become infected. The measles virus can remain in the air for up to two hours after an infected person leaves an area.

Another reason why measles spreads so easily is its long incubation period. In infected people, the time from exposure to fever is an average of about 10 days, and from exposure to rash onset is about 14 days — but could be up to 21 days. In addition, infected people are contagious from four days before rash starts through four days after. That’s a long period of time where they could unknowingly infect others.

CNN: What has been the cause of recent measles outbreaks?

Wen: It’s important to note that this incident in Kentucky is not yet considered an outbreak. Only one person has been diagnosed with measles. That person was possibly exposed to many others given the number of people in attendance at this gathering, but we don’t know yet if any of those people were infected.

But let’s look at a recent example of a confirmed outbreak in the US: In November 2022, health officials in central Ohio raised alarm over young children being diagnosed with measles. In all, 85 children got sick. None of the children died, but 36 needed to be hospitalized. All those infected were either unvaccinated or not yet fully vaccinated.

Health officials were able to contain the outbreak through contact tracing, vaccination and other public health measures in early February, and it was declared over. But there is concern it won’t be the last of its kind. A study from the CDC reported the rate of immunizations for required vaccines among kindergarten students nationwide dropped from 95% in the 2019-20 school year to 93% in the 2021-22 school year. Some communities have far lower rates than this national average, however, which can lead to outbreaks — not only of measles but also diseases like polio that can also have severe consequences.

CNN: How effective is the MMR vaccine?

Wen: The MMR vaccine is a two-dose vaccine. The recommendation is for children to receive the first dose at age 12-15 months and the second dose at age 4-6 years. One dose of the MMR vaccine 93% effective at preventing measles infection. Two doses are 97% effective.

CNN: What is the best way to protect against measles?

Wen: The MMR vaccine is an extremely safe and very effective vaccine and is recognized as a significant public health advance for preventing an otherwise extremely contagious disease from spreading and causing potentially very severe — even fatal — outcomes.

Consider that the vaccine was licensed in the US in 1963. In the four years before that, there were an average of more than 500,000 cases of measles every year and over 430 measles-associated deaths. By 1998, there were just 89 cases and no measles-associated deaths. That’s a huge public health triumph.

Young children should receive the vaccine according to the recommended schedule. Older kids and adults who never received it should also discuss getting it with their health care provider. And clinicians and public health officials in the US and around the world should redouble efforts to increase routine childhood immunizations so as to stop preventable diseases from making a comeback.

Celebrities may have helped shape anti-vaccine opinions during Covid-19 pandemic, study finds | CNN



CNN
 — 

Covid-19 vaccines are known to be safe and effective, and they’re available for free, but many Americans in the US refuse to get them – and a recent study suggests that celebrities may share some of the blame for people’s mistrust.

Celebrities have long tried to positively influence public health, studies show, but during the Covid-19 pandemic, they also seemed to have a large influence on spreading misinformation.

Decades ago, in the 1950s, people could see stars like Elvis Presley, Dick Van Dyke and Ella Fitzgerald in TV ads that encouraged polio vaccination. This celebrity influence boosted the country’s general vaccination efforts, and vaccination nearly eliminated the deadly disease.

In 2021, US officials used celebrities in TV ads to encourage more people to get vaccinated against Covid-19. Big names like lifestyle guru Martha Stewart, singer Charlie Puth and even Senate Minority Leader Mitchell McConnell showed up in spots that had billions of ad impressions.

The world isn’t restricted to only three TV networks any more, so celebrities like actress Hilary Duff, actor Dwayne “The Rock” Johnson, singer Dolly Parton and even Big Bird also used their enormous presence on Instagram and Twitter to promote a pro Covid-19 vaccine message.

But social media also became a vehicle for celebrities to cast doubt about the safety and effectiveness of the vaccine and even to spread disinformation about Covid.

Their negative messages seemed to find an audience.

For their study, published in the journal BMJ Health & Care Informatics, researchers examined nearly 13 million tweets between January 2020 and March 2022 about Covid-19 and vaccines. They designed a natural language model to determine the sentiment of each tweet and compared them with tweets that also mentioned people in the public eye.

The stars they picked to analyze included people who had shared skepticism about the vaccines, who had Covid-related tweets that were identified as misinformation or who retweeted misinformation about Covid.

They included rapper Nicki Minaj, football player Aaron Rodgers, tennis player Novak Djokovic, singer Eric Clapton, Sen. Rand Paul, former President Donald Trump, Sen. Ted Cruz, Florida Gov. Ron DeSantis, TV host Tucker Carlson and commentator Joe Rogan.

The researchers found 45,255 tweets from 34,407 unique authors talking about Covid-19 vaccine-related issues. Those tweets generated a total of 16.32 million likes. The tweets from these influencers, overall, were more negative about the vaccine than positive, the study found. These tweets were specifically more related to antivaccine controversy, rather than news about vaccine development, the study said.

The highest number of negative comments was associated with Rodgers and Minaj. Clapton had “very few” positive tweets, the study said, and that may have had an influence, but he also caught flak for it from the public.

The most-liked tweet that mentioned Clapton and the vaccine said, “Strongly disagree with [EC] … take on Covid and the vaccine and disgusted by his previous white supremacist comments. But if you reference the death of his son to criticize him, you are an ignorant scumbag.”

Trump and Cruz were found to have the most substantial impact within this group, with combined likes totaling more than 122,000.

They too came in for criticism on the topic, with many users wondering whether these politicians were qualified to have opinions about the vaccines. The study said the most-liked tweet mentioning Cruz was, “I called Ted Cruz’s office asking to make an appointment to talk with the Senator about my blood pressure. They told me that the Senator was not qualified to give medical advice and that I should call my doctor. So I asked them to stop advising about vaccines.”

The most-liked tweet associated with Rogan was an antivaxx statement: “I love how the same people who don’t want us to listen to Joe Rogan, Aaron Rodgers about the covid vaccine, want us to listen to Big Bird & Elmo.”

Posts shared by news anchors and politicians seemed to have the most influence in terms of the most tweets and retweets, the study found.

“Our findings suggest that the presence of consistent patterns of emotional content co-occurring with messaging shared by those persons in the public eye that we’ve mentioned, influenced public opinion and largely stimulated online public discourse, for the at least over the course of the first two years of the Covid pandemic,” said study co-author Brianna White, a research coordinator in the Population Health Intelligence lab at the University of Tennessee Health Science Center – Oak Ridge National Laboratory Center for Biomedical Informatics.

“We also argue that obviously as the risk of severe negative health outcomes increase with the failure to comply with health protective behavior recommendations, that our findings suggest that polarized messages from societal elite may downplay those severe negative health outcome risks.”

The study doesn’t get into exactly why celebrity tweets would have such an impact on people’s attitudes about the vaccine. Dr. Ellen Selkie, who has conducted research on influence at the intersection of social media, celebrity and public health outcomes, said celebrities are influential because they attract a lot of attention.

“I think part of the influence that media have on behavior has to do with the amount of exposure. Just in general, the volume of content that is focused on a specific topic or on a specific sort of interpretation of that topic – in this case misinformation – the repeated exposure to any given thing is going to increase the likelihood that it’s going to have an effect,” said Selkie, who was not involved in the new research. She is an adolescent health pediatrician and researcher with UW Health Kids and an assistant professor of pediatrics at the University of Wisconsin School of Medicine and Public Health.

Just as people listen to a friend’s thoughts, they’ll listen to a celebrity whom they tend to like or identify with because they trust their opinion.

“With fandoms, in terms of the relationship between musical artists and actors and their fans, there is this sort of mutual love that fans and artists have for each other, which sort of can approximate that sense that they’re looking out for each other,” Selkie said.

She said she would be interested to see research on the influence of celebrities who tweeted positive messages about the Covid-19 vaccine.

The authors of the study hope public health leaders will use the findings right away.

“We argue this threat to population health should create a sense of urgency and warrants public health response to identify, develop and implement innovative mitigation strategies,” the study says.

Exposure to large amounts of this misinformation can have a lasting impact and work against the public’s best interest when it comes to their health.

“As populations grow to trust the influential nature of celebrity activity on social platforms, followers are disarmed and open to persuasion when faced with false information, creating opportunities for dissemination and rapid spread of misinformation and disinformation,” the study says.

First on CNN: HHS secretary sends letter to state governors on what’s to come when Covid-19 public health emergency ends | CNN



CNN
 — 

Plans are moving forward at the US Department of Health and Human Services to prepare for the end of the nation’s Covid-19 public health emergency declaration in May.

On Thursday, HHS Secretary Xavier Becerra sent a letter and fact sheet to state governors detailing what exactly the end of the emergency declaration will mean for jurisdictions and their residents.

“Addressing COVID-19 remains a significant public health priority for the Administration, and over the next few months, we will transition our COVID-19 policies, as well as the current flexibilities enabled by the COVID-19 emergency declarations, into improving standards of care for patients. We will work closely with partners including state, local, Tribal, and territorial agencies, industry, and advocates, to ensure an orderly transition,” Becerra wrote in a draft of the letter obtained by CNN.

“In the coming days, the Centers for Medicare & Medicaid Services (CMS) will also provide additional information, including about the waivers many states and health systems have adopted and how they will be impacted by the end of the COVID-19 PHE,” he wrote. “I will share that resource with your team when available.”

Declaring a public health emergency in the United States means that certain actions, access to funds, grants, waivers and data – among other steps – can happen more quickly in response to the crisis for the duration of the emergency. A declaration lasts 90 days – unless HHS ends it – and may be renewed.

On January 30, the White House announced its intention to end the Covid-19 national and public health emergencies on May 11, signaling that the administration considers the nation to have moved out of the emergency response phase.

Becerra had agreed to give governors a 60-day notice to prepare for the end of the emergency. Thursday’s letter was sent 90 days ahead of the emergency’s planned end.

“We are having ongoing conversations about what else we need to do in the next 90 days to ensure a smooth transition. I can tell you that every one of our agencies has been working hard on this plan,” an HHS official told CNN. “We’re going to have a series of additional materials that will go out, as well as a series of conversations over the coming days and weeks.”

The end of the public health emergency will affect some Medicare and state Medicaid flexibilities provided for the duration of the emergency. This includes waivers like the requirement for a three-day hospital stay before Medicare will cover care at a skilled nursing facility.

“We’ve been working closely with the governors on the public health emergency. This is a combination of both federal flexibilities that we allow, and the states are often the ones who are using those flexibilities,” the HHS official said.

“Just about every aspect of the pandemic response, I would say, has been in partnership with our state partners. And so, I think they have been, frankly for months now, the ones that we have been going to and the ones that we publicly committed to notifying in advance of changes to the public health emergency declaration.”

But the emergency’s end will not impact the authorizations of Covid-19 devices, including tests, vaccines and treatments that have been authorized for emergency use by the US Food and Drug Administration.

During the Covid-19 pandemic, the FDA has issued about 15 times as many emergency use authorizations as it did for all other previous public health emergencies, Commissioner Dr. Robert Califf said Wednesday in a joint hearing of the House Oversight and Investigations and Health subcommittees.

“Today, we’ve issued EUAs or provided traditional marketing authorizations to over 2,800 medical devices for Covid-19, which is 15 times more EUAs than all other previous emergencies combined,” Califf said. He added that the effects of the end of the emergency declaration will be “modest” because the “EUAs are independent of the public health emergency, so we can keep them going as long as we need to.”

The emergency is slated to end May 11. “What happens on May 12? On May 12, you can still walk into a pharmacy and get your bivalent vaccine,” Dr. Ashish Jha, the White House’s coronavirus response coordinator, wrote on Twitter last week.

He said that at some point, probably in the summer or early fall, the Biden administration will transition from federal distribution of Covid-19 vaccines and treatments to purchases through the regular health care system – but that’s not happening quite yet.

Overall, there are additional Medicaid waivers and other flexibilities that states and territories have received under the public health emergency. Some of those will be terminated. But state Medicaid programs will have to continue covering Covid-19 testing, treatments, and vaccinations without cost-sharing through September 30, 2024.

The end of the public health emergency declaration means Medicare beneficiaries will face out-of-pocket costs for over-the-counter home Covid-19 tests and treatment. However, people with Medicare will continue to have no cost for medically necessary lab-conducted Covid-19 tests ordered by their health care providers.

Covid-19 vaccinations will continue to be covered at no cost for all Medicare beneficiaries.

Those with private insurance could face charges for lab tests, even if they are ordered by a provider, according to the Kaiser Family Foundation. Vaccinations will continue to be free for those with private insurance who go to in-network providers, but going to an out-of-network providers could incur charges once federal supplies run out.

And the privately insured will not be able to get free at-home tests from pharmacies and retailers anymore unless their insurers choose to cover them.

Americans with private insurance have not been charged for monoclonal antibody treatment since they were prepaid by the federal government, though patients may be charged for the office visit or administration of the treatment, according to Kaiser. But that is not tied to the public health emergency, and the free treatments will be available until the federal supply is exhausted. The government has already run out of some of the treatments so those with private insurance may already be picking up some of the cost.

The uninsured had been able to access no-cost testing, treatments and vaccines through a different pandemic relief program. However, the federal funding ran out in the spring of 2022, making it more difficult for those without coverage to obtain free services.

Also, the “ability of health care providers to safely dispense controlled substances via telemedicine without an in-person interaction is affected; however, there will be rulemaking that will propose to extend these flexibilities,” according to the letter’s fact sheet.

One of the most meaningful pandemic enhancements for states is no longer tied to the public health emergency. Congress severed the connection in December as part of its fiscal year 2023 government funding package, which state Medicaid officials had urged lawmakers to do.

States will now be able to start processing Medicaid redeterminations and disenrolling residents who no longer qualify, starting April 1. They have 14 months to review the eligibility of their beneficiaries.

As part of a Covid-19 relief package passed in March 2020, states were barred from kicking people off Medicaid during the public health emergency in exchange for additional federal matching funds. Medicaid enrollment has skyrocketed to a record 91 million people since then.

A total of roughly 15 million people could be dropped from Medicaid when the continuous enrollment requirement ends, according to an analysis the Department of Health and Human Services released in August. About 8.2 million folks would no longer qualify, but 6.8 million people would be terminated even though they are still eligible, the department estimated.

Many who are disenrolled from Medicaid, however, could qualify for other coverage.

Cancer is striking more people in their 30s and 40s. Here’s what you need to know | CNN



CNN
 — 

It’s World Cancer Day, and the outlook for winning the war against this deadly disease is both good and bad.

In the United States, deaths from cancer have dropped 33% since 1991, with an estimated 3.8 million lives saved, mostly due to advances in early detection and treatment. Still, 10 million people worldwide lost their lives to cancer in 2020.

“During the last three years, the No. 1 leading leading cause of death in the world was actually cancer, not Covid-19,” said Dr. Arif Kamal, chief patient officer for the American Cancer Society.

Symptoms of cancer can mimic those of many other illnesses, so it can be difficult to tell them apart, experts say. Signs include unexplained weight loss or gain, swelling or lumps in the groin, neck, stomach or underarms and fever and night sweats, according to the National Cancer Institute.

Bladder, bowel, skin and neurological issues may be signs of cancer, such as changes in hearing and vision, seizures, headaches and bleeding or bruising for no reason, the institute said. But most cancers do not cause pain at first, so you can’t rely on that as a sign.

“We tell patients that if they have symptoms that do not get better after a few weeks, they should visit a doctor,” Kamal said. “It doesn’t mean the diagnosis will be cancer, however.”

Rather than wait for symptoms, the key to keeping cancer at bay is prevention, along with screenings to detect the disease in its early stages. That’s critical, experts say, as new cases of cancer are on the rise globally.

A surprising number of new diagnoses are in people under 50, according to a 2022 review of available research by Harvard University scientists.

Cases of breast, colon, esophagus, gallbladder, kidney, liver, pancreas, prostate, stomach and thyroid cancers have been increasing in 50-, 40- and even 30-year-olds since the 1990s.

That’s unusual for a disease that typically strikes people over 60, Kamal said. “Cancer is generally considered an age-related condition, because you’re giving yourself enough time to have sort of a genetic whoopsie.”

Older cells experience decades of wear and tear from environmental toxins and less than favorable lifestyle choices, making them prime candidates for a cancerous mutation.

“We believed it takes time for that to occur, but if someone is 35 when they develop cancer, the question is ‘What could possibly have happened?’” Kamal asked.

No one knows exactly, but smoking, alcohol consumption, air pollution, obesity, a lack of physical activity and a diet with few fruits and vegetables are key risk factors for cancer, according to the World Health Organization.

Add those up, and you’ve got a potential culprit for the advent of early cancers, the Harvard researchers said.

“The increased consumption of highly processed or westernized foods together with changes in lifestyles, the environment … and other factors might all have contributed to such changes in exposures,” the researchers wrote in their 2022 review.

“You don’t need 65 years of eating crispy, charred or processed meat as a main diet, for example,” Kamal added. “What you need is about 20 years, and then you start to see stomach and colorectal cancers, even at young ages.”

So how do you fight back against the big C? Start in your 20s, Kamal said.

Many of the most common cancers, including breast, bowel, stomach and prostate, are genetically based — meaning that if a close relative has been diagnosed, you may have inherited a predisposition to develop that cancer too.

That’s why it’s critical to know your family’s health history. Kamal suggests young people sit down with their grandparents and other close relatives and ask them about their illnesses — and then write it down.

“The average person doesn’t actually know the level of granularity that is helpful in accessing risk,” he said.

“When I talk to patients, what they’ll say is, ‘Oh, yeah, Grandma had cancer.’ There’s two questions I want to know: At what age was the cancer diagnosed, and what specific type of cancer was it? I need to know if she had cancer in her 30s or 60s, because it determines your level of risk. But they often don’t know.”

The same applies to the type of cancer, Kamal said.

“People often say ‘Grandma had bone cancer.’ Well, multiple myeloma and osteosarcoma are bone cancers, but both of them are relatively rare,” he said. “So I don’t think Grandma had bone cancer. I think Grandma had another cancer that went to the bone, and I need to know that.”

Next, doctors need to know what happened to that relative. Was the cancer aggressive? What was the response to treatment?

“If I hear Mom or Grandma was diagnosed with breast cancer at 40 and passed away at 41, then I know that cancer is very aggressive, and that changes my sense of your risk. I may add additional tests that aren’t in the guidelines for your age.”

Cancer screening guidelines are based on population-level assessments, not individual risk, Kamal said. So, if cancer (or other conditions such as heart disease, diabetes, Alzheimer’s, or even migraines) runs in the family, you become a special case and need a personalized plan.

“And I will tell you the entire scientific community is observing this younger age shift for different cancers and is asking itself: ‘Should guidelines be more deliberate and intentional for younger populations to give them some of this advice?”

Report: Black women more likely to die from breast cancer

If your family history is clear of cancer, that lowers your risk — but doesn’t remove it. You can decrease the likelihood of cancer by eating a healthy, plant-based diet, getting the recommended amount of exercise and sleep, limiting alcohol consumption and not smoking or vaping, experts say.

Protecting yourself from the sun and tanning beds is key, too, as harmful ultraviolet rays damage DNA in skin cells and are the prime risk factor for melanoma. However, skin cancer can show up even where the sun doesn’t shine, Kamal said.

“There’s been an increase of melanoma that’s showing up in non-sun-exposed areas such as the underarm, the genital area and between the toes,” he said. “So it’s important to check — or have a partner or dermatologist check — your entire body once a year.”

Skin check: Take off all your clothes and look carefully at all of your skin, including the palms, soles of feet, between toes and buttocks and in the genital area. Use the A, B, C, D, E method to analyze any worrisome spots and then see a specialist if you have concerns, the American Academy of Dermatology advised.

Also see a dermatologist if you have any itching, bleeding or see a mole that looks like an “ugly duckling” and stands out from the rest of the spots on your body.

Get vaccinated if you haven’t: Two vaccinations protect against cervical and liver cancers, and others for cancers such as melanoma are in development.

Hepatitis B is transmitted via blood and sexual fluids and can cause liver cancer and cirrhosis, which is a scarred and damaged liver. A series of three shots, starting at birth, is part of the US recommended childhood vaccines schedule. Unvaccinated adults should check with their doctor to see if they are eligible.

The HPV vaccine protects against several strains of human papillomavirus, the most common sexually transmitted infection, according to the US Centers for Disease Control and Prevention.

Human papillomavirus can cause deadly cervical cancer as well as vaginal, anal and penile cancer. It can also cause cancer in the back of the throat, including the tongue and tonsils.

“These HPV-related head and neck cancers are more aggressive than the non-HPV-related cancers,” Kamal said, “so boys as well as girls should be vaccinated.”

Since the vaccine’s approval in 2006 in the US for adolescents ages 11 to 13, cervical cancer rates have declined by 87%. Today, the vaccine can be given through age 45, the CDC said.

Breast self-exams: Breast cancer is the most common type of cancer diagnosed worldwide, according to the WHO, followed by lung, colorectal, prostate, skin and stomach cancers.

Both men and women can get breast cancer, so men with a family history should be aware of the symptoms as well, experts say. These include pain, redness or irritation, dimpling, thickening or swelling of any part of the breast. New lumps, either in the breast or armpit, any pulling in of the nipple and nipple discharge other than breast milk are also worrisome symptoms, the CDC said.

Women should do a self-exam once a month and see a doctor if there are any warning signs, the National Breast Cancer Association advised. Choose a time when the breasts will be less tender and lumpy, which is about seven to 10 days after the beginning of the menstrual flow.

Screenings and tests: At-home exams and vaccinations can save lives, but many cancers can only be detected through laboratory tests, scans or biopsies. The American Cancer Society has a list of recommended screening by ages.

Getting those done in a timely manner increases the chance for early detection and treatment, but it’s still each person’s responsibility to know their risk factors, Kamal said.

“Remember, guidelines are only for people at average risk,” he said. “The only way someone can know whether the guidelines apply to them is to really understand their family history.”

Mpox is almost gone in the US, leaving lessons and mysteries in its wake | CNN



CNN
 — 

The US public health emergency declaration for mpox, formerly known as monkeypox, ends Tuesday.

The outbreak, which once seemed to be spiraling out of control, has quietly wound down. The virus isn’t completely gone, but for more than a month, the average number of daily new cases reported to the US Centers for Disease Control and Prevention has hovered in the single digits, plummeting from an August peak of about 450 cases a day.

Still, the US led the world in cases during the 2022-23 outbreak. More than 30,000 people in the US have been diagnosed with mpox, including 23 who died.

Cases are also down across Europe, the Western Pacific and Asia but still rising in some South American countries, according to the latest data from the World Health Organization.

It wasn’t always a given that we’d get here. When mpox went global in 2022, doctors had too few doses of a new and unproven vaccine, an untested treatment, a dearth of diagnostic testing and a difficult line to walk in their messaging, which needed to be geared to an at-risk population that has been stigmatized and ignored in public health crises before.

Experts say the outbreak has taught the world a lot about this infection, which had only occasionally been seen outside Africa.

But even with so much learned, there are lingering mysteries too – like where this virus comes from and why it suddenly began to spread from the Central and West African countries where it’s usually found to more than 100 other nations.

Before May 2022, when clusters of people with unusual rashes began appearing in clinics in the UK and Europe, the country reporting the most cases of mpox was the Democratic Republic of Congo, or DRC.

There, cases have been steadily building since the 1970s, according to a study in the CDC’s Morbidity and Mortality Weekly Report.

In the DRC, people in rural villages depend on wild animals for meat. Many mpox infections there are thought to be the result of contact with an animal to which the virus has adapted; this animal host is not known but is assumed to be a rodent.

For years, experts who studied African outbreaks observed a phenomenon known as stuttering chains of transmission: “infections that managed to transmit themselves or be transmitted from person to person to a limited degree, a certain number of links in that chain of transmission, and then suddenly just aren’t able to sustain themselves in humans,” said Stephen Morse, an epidemiologist at Columbia University’s Mailman School of Public Health.

Informally, scientists kept track, and Morse says that for years, the record for links in a mpox chain was about four.

“Traditionally, it always burned itself out,” he said.

Then the chains started getting longer.

In 2017, Nigeria – which hadn’t had a confirmed case of mpox in more than four decades – suddenly saw a resurgence of the virus, with more than 200 cases reported that year.

“People have speculated maybe it was a change in the virus that allowed it to be made better-adapted to humans,” Morse said.

From 2018 through 2021, eight cases of mpox were reported outside Africa. All were in men ages 30 to 50, and all had traveled from Nigeria. Three reported that the rashes had started in their groin area. One went on to infect a health care provider. Another infected two family members.

This Nigerian outbreak helped experts realize that mpox could efficiently spread between people.

It also hinted that the infection could be sexually transmitted, but investigators couldn’t confirm this route of spread, possibly because of the stigma involved in sharing information about sexual contact.

In early May 2022, health officials in the UK began reporting confirmed cases of mpox. One of the people had recently traveled to Nigeria, but others had not, indicating that it was spreading in the community.

Later, other countries would report cases that had started even earlier, in April.

Investigators concluded that mpox had been silently spreading before they caught up to it.

In early summer, as US case numbers began to grow, the public health response bore some uncomfortable similarities to the early days of Covid-19. People with suspicious rashes complained that it was too hard to get tested because a limited supply was being rationed. Because the virus had so rarely appeared outside certain countries in Africa, most doctors weren’t sure how to recognize mpox or how to test for it and didn’t understand all its routes of spread.

A new vaccine was available, and the government had placed orders for it, but most of those doses weren’t in the United States. Beyond that, its efficacy against mpox had been studied only in animals, so no one knew whether it would actually work in humans.

There was an experimental treatment, Tpoxx, but it too was unproven, and doctors could get it only after filling out reams of paperwork required by the government for compassionate use.

Some just gave up.

“Tpoxx was hard to get,” said Dr. Jeffrey Klausner, a clinical professor of public health at the University of Southern California’s Keck School of Medicine.

“I was scrambling to find places that could prescribe it because my own institution just became a bureaucratic nightmare. So I basically would be referring people for treatment outside my own institution to be able to get monkeypox treatment,” he said.

Finally, in August, the federal government declared a public health emergency. This allowed federal agencies to access pots of money set aside for emergencies. It also allows the government to shift funds from one purpose to another to help cover costs of the response – and it helped raise awareness among doctors that mpox was something to watch for.

The government also set up a task force led by Robert Fenton, a logistics expert from the Federal Emergency Management Agency, and Dr. Demetre Daskalakis, director of the CDC’s Division of HIV and AIDS Research.

Daskalakis is openly gay and sex-positive, right down to his Instagram account, which mixes suit-and-tie shots from White House briefings with photos revealing his many tattoos.

“Dr. Daskalakis … really walks on water in most of the gay community, and then [Fenton is] a logistics expert, and I think that combination of leadership was the right answer,” Klausner said.

Early on, after the CDC identified men who have sex with men as being at highest risk of infection, officials warned of close physical contact, the kind that often happens with sexual activity. They also noted that people could be infected through contact with contaminated surfaces like sheets or towels.

But they stopped short of calling it a sexually transmitted infection, a move that some saw as calculated.

“In this outbreak, in this time and context to Europe, United States and Australia, was definitely sexually transmitted,” said Klausner, who points out that many men got rashes on their genitals and that infectious virus was cultured in semen.

Klausner believes vague descriptions about how the virus spread were intentional, in order to garner resources needed for the response.

“People felt that if they called it an STD from the get-go, it was going to create stigma, and because of the stigma of the type of sex that was occurring – oral sex, anal sex, anal sex between same-sex male partners – there may not have been the same kind of federal response,” Klausner said. “So it was actually a political calculation to garner the resources necessary to have a substantial response to be vague about how it spread.”

This ambiguity created room for misinformation and confusion, said Tony Hoang, executive director of Equality California, a nonprofit advocacy group for LGBTQ civil rights.

“I think there was a balancing dance of not wanting to create stigma, in terms of who is actually the highest rates of transmission without being forthright,” Hoang said.

Hoang’s group launched its own public information campaign, combining information from the CDC on HIV and mpox. The messaging stressed that sex was the risky behavior and made sure to explain that light brushes or touches weren’t likely to pass the infection, he said.

Klausner thinks the CDC could have done better on messaging.

“By giving vague, nonspecific information and making comments like ‘everyone’s potentially at risk’ or ‘there’s possible spread through sharing a bed, clothing or close dancing’ … that kind of dilutes the message, and people who engage in risk behavior that does put them at risk get confused, and they say ‘well, maybe this isn’t really a route of spread,’ ” he said.

In July and August, when the US was reporting hundreds of new mpox cases each day, health officials were worried that the virus might be here to stay.

“There were concerns that there would be ongoing transmission and that ongoing transmission would become endemic in the United States like other STIs: gonorrhea, chlamydia, syphilis. We have not seen that occur,” said Dr. Jonathan Mermin, director of the CDC’s National Center for HIV, Viral Hepatitis, STD, and TB Prevention.

“We are now seeing three to four cases a day in the United States, and it continues to decline. And we see the possibility of getting to zero as real,” he said.

At the peak of the outbreak, officials scrambled to vaccinate the population at highest risk – men who have sex with men – in the hopes of limiting both severity of infections and transmission. But no one was sure whether this strategy would work.

The Jynneos vaccine was approved by the US Food and Drug Administration in 2019 to prevent monkeypox and smallpox in people at high risk of those infections.

At that time, the plan was to bank it in the Strategic National Stockpile as a countermeasure in case smallpox was weaponized. The approval for mpox, a virus closely related to smallpox, was tacked on because the US had seen a limited outbreak of these infections in 2003, tied to the importation of exotic rodents as pets.

Jynneos had passed safety tests in humans. In lab studies, it protected primates and mice from mpox infections. But researchers only learn how effective vaccines are during infectious disease outbreaks, and Jynneos has never been put through its paces during an outbreak.

“We were left, when this started, with that great unknown: Does this vaccine work? And is it safe in large numbers?” Mermin said.

Beyond those uncertainties, there wasn’t enough to go around, and infectious disease experts feared that a shortage of the vaccine might thwart any effort to stop the outbreak.

So public health officials announced a change in strategy: Instead of injecting a full dose under the skin, or subcutaneously, they would inject just one-fifth of that dose between the skin’s upper layers, or intradermally.

An early study in the trials of the vaccine had suggested that intradermal dosing could be effective, but it was a risk. Again, no one was sure this dose-sparing strategy would work.

Ultimately, all of these gambles appear to have paid off.

Early studies of vaccine effectiveness show that the Jynneos vaccine protected men from mpox infections. According to CDC data, people who were unvaccinated were almost 10 times as likely to be diagnosed with the infection as those who got the recommended two doses.

Men who had two doses were about 69% less likely, and men with a single dose were about 37% less likely, to have an mpox infection that needed medical attention compared with those who were unvaccinated, according to the CDC.

Mermin says studies have since showed that the vaccine worked well no matter if was given into the skin or under the skin – another win.

Still, the vaccine is almost certainly not the entire reason cases have plunged, simply because not enough people have gotten it. The CDC estimates that 2 million people in the United States are eligible for mpox vaccination. Mermin says that about 700,000 have had a first dose – about 36% of the eligible population.

So it’s unlikely that vaccination was the only reason for the steep decline in cases. CDC modeling suggests that behavior change may have played a substantial role, too.

In an online survey of men who have sex with men conducted in August, half of participants indicated that they had reduced their number of partners and one-time sexual encounters, behaviors that could cut the growth of new infections by 20% to 30%.

If that’s the case, some experts worry that the US could see monkeypox flare up again as the weather warms.

“The party season was during the summer, during the height of the outbreak, and we’re in the dead of winter. So there’s a possibility that behavior change may not able to be sustained,” said Gregg Gonsalves, an epidemiologist at the Yale School of Public Health.

Although we’re clearly in a much better position than we were last summer, he says, public health officials shouldn’t make this a “mission accomplished” moment.

“Now, put your foot on the accelerator. Let’s get the rest of these cases,” Gonsalves said.

Mermin says that’s exactly what the CDC intends to do. It isn’t finished with the response but intends to switch to “a ground game.”

“So much of our work in the next few months will be setting up structures so that getting vaccinated is easy,” he said.

Nearly 40% of mpox cases in the United States were diagnosed in people who also had HIV, Mermin said. So the CDC is going to make sure Jynneos vaccines are available as a routine part of care at HIV clinics and STI clinics that offer pre-exposure prophylaxis, or PrEP, for HIV.

Mermin said officials are also going to continue to go to LGBTQ festivals and events to offer on-site vaccinations.

Additionally, they’re going to study people who’ve been vaccinated and infected to see whether they remain immune – something else that’s still a big unknown.

Experts say that’s just one of many questions that need a closer look. Another is just how long the virus had been spreading outside Africa before the world noticed.

“We’re starting to see some data that suggests that asymptomatic infection and transmission is possible, and that certainly will change how we how we think about this virus and and risk,” said Anne Rimoin, an epidemiologist at the Fielding School of Public Health at UCLA.

When researchers at a sexual health clinic in Belgium rescreened more than 200 nasal and oral swabs they had taken in May 2022 to test for the STIs chlamydia and gonorrhea, they found positive mpox cases that had gone undiagnosed. Three of the people reported no symptoms, while another reported a painful rash, which was misdiagnosed as herpes. Their study was published in the journal Nature Medicine.

“Mild and asymptomatic infections may have indeed delayed the detection of the outbreak,” study author Christophe Van Dijck of the Laboratory of Medical Microbiology at the University of Antwerp in Belgium said in an email to CNN.

While researchers tackle those pursuits, advocacy groups say they aren’t ready to relax.

Hoang says Equality California is pushing the CDC to address continuing racial disparities in mpox vaccination and treatment, particularly in rural areas.

He’s not worried that gay men will drop their guard now that the emergency has expired..

“We’ve learned that we have to take health into our own hands, and I do think that we will remain vigilant as a community for this outbreak and future outbreaks,” Hoang said.

FDA vaccine advisers vote to harmonize Covid-19 vaccines in the United States | CNN



CNN
 — 

A panel of independent experts that advises the US Food and Drug Administration on its vaccine decisions voted unanimously Thursday to update all Covid-19 vaccines so they contain the same ingredients as the two-strain shots that are now used as booster doses.

The vote means young children and others who haven’t been vaccinated may soon be eligible to receive two-strain vaccines that more closely match the circulating viruses as their primary series.

The FDA must sign off on the committee’s recommendation, which it is likely to do, before it goes into effect.

Currently, the US offers two types of Covid-19 vaccines. The first shots people get – also called the primary series – contain a single set of instructions that teach the immune system to fight off the original version of the virus, which emerged in 2019.

This index strain is no longer circulating. It was overrun months ago by an ever-evolving parade of new variants.

Last year, in consultation with its advisers, the FDA decided that it was time to update the vaccines. These two-strain, or bivalent, shots contain two sets of instructions; one set reminds the immune system about the original version of the coronavirus, and the second set teaches the immune system to recognize and fight off Omicron’s BA.4 and BA.5 subvariants, which emerged in the US last year.

People who have had their primary series – nearly 70% of all Americans – were advised to get the new two-strain booster late last year in an effort to upgrade their protection against the latest variants.

The advisory committee heard testimony and data suggesting that the complexity of having two types of Covid-19 vaccines and schedules for different age groups may be one of the reasons for low vaccine uptake in the US.

Currently, only about two-thirds of Americans have had the full primary series of shots. Only 15% of the population has gotten an updated bivalent booster.

Data presented to the committee shows that Covid-19 hospitalizations have been rising for children under the age of 2 over the past year, as Omicron and its many subvariants have circulated. Only 5% of this age group, which is eligible for Covid-19 vaccination at 6 months of age, has been fully vaccinated. Ninety percent of children under the age of 4 are still unvaccinated.

“The most concerning data point that I saw this whole day was that extremely low vaccination coverage in 6 months to 2 years of age and also 2 years to 4 years of age,” said Dr. Amanda Cohn, director of the US Centers for Disease Control and Prevention’s Division of Birth Defects and Infant Disorders. “We have to do much, much better.”

Cohn says that having a single vaccine against Covid-19 in the US for both primary and booster doses would go a long way toward making the process less complicated and would help get more children vaccinated.

Others feel that convenience is important but also stressed that data supported the switch.

“This isn’t only a convenience thing, to increase the number of people who are vaccinated, which I agree with my colleagues is extremely important for all the evidence that was related, but I also think moving towards the strains that are circulating is very important, so I would also say the science supports this move,” said Dr. Hayley Gans, a pediatric infectious disease specialist at Stanford University.

Many others on the committee were similarly satisfied after seeing new data on the vaccine effectiveness of the bivalent boosters, which are cutting the risk of getting sick, being hospitalized or dying from a Covid-19 infection.

“I’m totally convinced that the bivalent vaccine is beneficial as a primary series and as a booster series. Furthermore, the updated vaccine safety data are really encouraging so far,” said Dr. David Kim, director of the the US Department of Health and Human Services’ National Vaccine Program, in public discussion after the vote.

Thursday’s vote is part of a larger plan by the FDA to simplify and improve the way Covid-19 vaccines are given in the US.

The agency has proposed a plan to convene its vaccine advisers – called the Vaccines and Related Biological Products Advisory Committee, or VRBPAC – each year in May or June to assess whether the instructions in the Covid-19 vaccines should be changed to more closely match circulating strains of the virus.

The time frame was chosen to give manufacturers about three months to redesign their shots and get new doses to pharmacies in time for fall.

“The object, of course – before anyone says anything – is not to chase variants. None of us think that’s realistic,” said Jerry Weir, director of the Division of Viral Products in the FDA’s Office of Vaccines Research and Review.

“But I think our experience so far, with the bivalent vaccines that we have, does indicate that we can continue to make improvements to the vaccine, and that would be the goal of these meetings,” Weir said.

In discussions after the vote, committee members were supportive of this plan but pointed out many of the things we still don’t understand about Covid-19 and vaccination that are likely to complicate the task of updating the vaccines.

For example, we now seem to have Covid-19 surges in the summer as well as the winter, noted Dr. Michael Nelson, an allergist and immunologist at the University of Virginia. Are the surges related? And if so, is fall the best time to being a vaccination campaign?

The CDC’s Dr. Jefferson Jones said that with only three years of experience with the virus, it’s really too early to understand its seasonality.

Other important questions related to the durability of the mRNA vaccines and whether other platforms might offer longer protection.

“We can’t keep doing what we’re doing,” said Dr. Bruce Gellin, chief of global public health strategy at the Rockefeller Foundation. “It’s been articulated in every one of these meetings despite how good these vaccines are. We need better vaccines.”

The committee also encouraged both government and industry scientists to provide a fuller picture of how vaccination and infection affect immunity.

One of the main ways researchers measure the effectiveness of the vaccines is by looking at how much they increase front-line defenders called neutralizing antibodies.

Neutralizing antibodies are like firefighters that rush to the scene of an infection to contain it and put it out. They’re great in a crisis, but they tend to diminish in numbers over time if they’re not needed. Other components of the immune system like B-cells and T-cells hang on to the memory of a virus and stand ready to respond if the body encounters it again.

Scientists don’t understand much about how well Covid-19 vaccination boosts these responses and how long that protection lasts.

Another puzzle will be how to pick the strains that are in the vaccines.

The process of selecting strains for influenza vaccines is a global effort that relies on surveillance data from other countries. This works because influenza strains tend to become dominant and sweep around the world. But Covid-19 strains haven’t worked in quite the same way. Some that have driven large waves in other countries have barely made it into the US variant mix.

“Going forward, it is still challenging. Variants don’t sweep across the world quite as uniform, like they seem to with influenza,” the FDA’s Weir said. “But our primary responsibility is what’s best for the US market, and that’s where our focus will be.”

Eventually, the FDA hopes that Americans would be able to get an updated Covid-19 shot once a year, the same way they do for the flu. People who are unlikely to have an adequate response to a single dose of the vaccine – such as the elderly or those with a weakened immune system – may need more doses, as would people who are getting Covid-19 vaccines for the first time.

At Thursday’s meeting, the advisory committee also heard more about a safety signal flagged by a government surveillance system called the Vaccine Safety Datalink.

The CDC and the FDA reported January 13 that this system, which relies on health records from a network of large hospital systems in the US, had detected a potential safety issue with Pfizer’s bivalent boosters.

In this database, people 65 and older who got a Pfizer bivalent booster were slightly more likely to have a stroke caused by a blood clot within three weeks of their vaccination than people who had gotten a bivalent booster but were 22 to 42 days after their shot.

After a thorough review of other vaccine safety data in the US and in other countries that use Pfizer bivalent boosters, the agencies concluded that the stroke risk was probably a statistical fluke and said no changes to vaccination schedules were recommended.

At Thursday’s meeting, Dr. Nicola Klein, a senior research scientist with Kaiser Permanente of Northern California, explained how they found the signal.

The researchers compared people who’d gotten a vaccine within the past three weeks against people who were 22 to 42 days away from their shots because this helps eliminate bias in the data.

When they looked to see how many people had strokes around the time of their vaccination, they found an imbalance in the data.

Of 550,000 people over 65 who’d received a Pfizer bivalent booster, 130 had a stroke caused by a blood clot within three weeks of vaccination, compared with 92 people in the group farther out from their shots.

The researchers spotted the signal the week of November 27, and it continued for about seven weeks. The signal has diminished over time, falling from an almost two-fold risk in November to a 47% risk in early January, Klein said. In the past few days, it hasn’t been showing up at all.

Klein said they didn’t see the signal in any of the other age groups or with the group that got Moderna boosters. They also didn’t see a difference when they compared Pfizer-boosted seniors with those who were eligible for a bivalent booster but hadn’t gotten one.

Further analyses have suggested that the signal might be happening not because people who are within three weeks of a Pfizer booster are having more strokes, but because people who are within 22 to 42 days of their Pfizer boosters are actually having fewer strokes.

Overall, Klein said, they were seeing fewer strokes than expected in this population over that period of time, suggesting a statistical fluke.

Another interesting thing that popped out of this data, however, was a possible association between strokes and high-dose flu vaccination. Seniors who got both shots on the same day and were within three weeks of those shots had twice the rate of stroke compared with those who were 22 to 42 days away from their shots.

What’s more, Klein said, the researchers didn’t see the same association between stroke and time since vaccination in people who didn’t get their flu vaccine on the same day.

The total number of strokes in the population of people who got flu shots and Covid-19 boosters on the same day is small, however, which makes the association a shaky one.

“I don’t think that the evidence are sufficient to conclude that there’s an association there,” said Dr. Tom Shimabukuro, director of the CDC’s Immunization Safety Office.

Nonetheless, Richard Forshee, deputy director of the FDA’s Office of Biostatistics and Pharmacovigilance, said the FDA is planning to look at these safety questions further using data collected by Medicare.

The FDA confirmed that the agency is taking a closer look.

“The purpose of the study is 1) to evaluate the preliminary ischemic stroke signal reported by CDC using an independent data set and more robust epidemiological methods; and 2) to evaluate whether there is an elevated risk of ischemic stroke with the COVID-19 bivalent vaccine if it is given on the same day as a high-dose or adjuvanted seasonal influenza vaccine,” a spokesperson said in a statement.

The FDA did not give a time frame for when these studies might have results.

It’s been three years since the first Covid-19 case in the United States. What have we learned and what more do we need to understand? | CNN



CNN
 — 

It’s been three years since the first Covid-19 case was diagnosed in the United States, on January 20, 2020. In the time since, nearly 1.1 million Americans have died from the coronavirus; the US has reported 102 million Covid cases, more than any other country, according to Johns Hopkins University. Both figures, many health officials believe, are likely to have been undercounted.

There have also been remarkable scientific achievements in our response to the pandemic, not least of which is the development of Covid-19 vaccines. But there are still many unanswered questions. To help with reflections on what we’ve learned and what more we need to understand, I spoke with CNN Medical Analyst Dr. Leana Wen, an emergency physician, public health expert and professor of health policy and management at the George Washington University Milken Institute School of Public Health. She is also author of “Lifelines: A Doctor’s Journey in the Fight for Public Health.”

CNN: You’re a physician caring for patients, a public health researcher and professor. What are the key lessons you’ve learned from the last three years of Covid-19?

Dr. Leana Wen: There are three main lessons that come to mind. First, we have seen how much the global scientific community has come together and delivered some truly incredible achievements. Less than a year after Covid-19 was declared a pandemic, we had a vaccine developed, authorized and being distributed. The scientific community has rallied on many other aspects of the response to Covid-19, including to identify treatments and improve surveillance testing.

Many of the scientific developments will last beyond this pandemic and help with other aspects of our infectious disease response. For instance, the technology behind mRNA vaccines could be used to make vaccines for other diseases. The wastewater surveillance being used to identify and track Covid-19 may be helpful for detecting other viruses.

Second, Covid-19 has unmasked many existing crises and amplified them for the world to see. The coronavirus didn’t create health disparities — these long-predated the virus — but exacerbated existing ones.

There were also many faults with the public health infrastructure that, while long known to those of us in the field, have been exposed for all to see. Data systems are not integrated between public health agencies, for example, and city and county health departments are woefully underfunded given their many responsibilities. These stem from the fragmented health care system we have in the US, as well as the ongoing lack of investment in local public health agencies.

At the same time, Covid has also demonstrated how crucial public health is. There is a saying that “public health saved your life today, you just don’t know it.” I think there is much more recognition among many that public health is essential to preventing problems that can have a major impact on people’s health and well-being.

With that said, Covid-19 occurred during a time of deep division. Virtually every aspect of the pandemic has become politicized and polarized. So thirdly, there has been rampant misinformation and disinformation that’s made the response much more challenging. We are seeing the lasting effects, such as reduced uptake of routine childhood immunizations. I’m very concerned that public health itself has become politicized in a way that could harm our response to future pandemics.

CNN: You mentioned that we’ve learned a lot scientifically. What more do we need to understand about Covid-19?

Wen: At this point in the pandemic, a lot of people have moved on from Covid-19 and no longer think about it as a major factor in their everyday lives. However, there are millions of Americans vulnerable to severe illness who remain very concerned about the coronavirus. These are people who are immunocompromised, elderly or with multiple underlying illnesses. To me, the most important research questions pertain to these individuals.

There are some antiviral medications that are effective for Covid-19 treatment, such as Paxlovid. Some patients are not eligible for Paxlovid, though, and other options are becoming more limited. The US Food and Drug Administration has revoked their authorization for monoclonal antibodies that could treat Covid-19 infection, as they no longer appear to be effective against new circulating variants. Recently, the FDA has also said that the preventive antibody Evusheld may be ineffective against some variants, including the XBB.1.5 variant that’s currently dominant in the US.

It should be an urgent priority to focus on developing better treatments for those most vulnerable to severe disease from Covid-19. I also hope that there will be much more investment into finding better vaccines. The vaccines that we have are excellent at protecting against severe disease, which is most important. However, they are not very effective at preventing infection.

The ideal vaccine would be more effective at reducing infection, and target the virus broadly so that we are not always trying to anticipate what variant will develop next — and then scrambling to find a vaccine that works against that variant. There is research being undertaken into nasal vaccines and pan-coronavirus vaccines, for example. I hope these efforts will be expedited.

CNN: We are learning more about long Covid, but is this an area that needs more research?

Wen: Absolutely. We know that many people have lingering symptoms after a Covid-19 infection. According to a large study from Israel, most symptoms resolve within the first year after infection for people with mild illness. However, there are some who have lasting symptoms, like fatigue, headache, palpitations and shortness of breath, that are so debilitating they can no longer work.

There is a lot that we don’t yet know about long Covid. The most important is how to treat patients who have it. The physiological mechanisms behind what’s causing their lingering symptoms are also unclear, along with exactly how common they are.

There are long waits to get into specialized clinics that treat this condition at present, so a lot more education needs to be done for primary care physicians and other clinicians who will probably end up being the main health care providers for many people suffering from long Covid.

CNN: What do you anticipate will happen in this coming year around Covid-19?

Wen: Right now, China is undergoing a massive surge of cases. It’s the last major country to have enforced a strict zero-Covid policy, and now that policy has been reversed. Once China’s infection numbers stabilize, Covid-19 will probably become endemic there, as it has become in most other parts of the world.

There will, no doubt, be new variants that arise. We need to keep on top of them and monitor accordingly to see if they are more deadly and/or evade the effectiveness of existing vaccines. The key, as I said earlier, is to develop vaccines that can more broadly cover variants.

And we must again remember that, while many people have resumed pre-pandemic lives, others have not. In the next year of Covid-19, I believe that the focus needs to be much more specific to these individuals who need our help the most. We should target boosters and treatments to those most vulnerable, for example.

Finally, there should be a much greater effort to rebuild our public health infrastructure. This is long overdue. Doing so is critical not just for preparing for the next pandemic, but also for improving health and well-being for all Americans.

Flu, Covid-19 and RSV are all trending down for the first time in months | CNN



CNN
 — 

A rough respiratory virus season in the US appears to be easing, as three major respiratory viruses that have battered the country for the past few months are finally all trending down at the same time.

A new dataset from the US Centers for Disease Control and Prevention shows that the number of emergency department visits for the three viruses combined – flu, Covid-19 and RSV – have dropped to the lowest they’ve been in three months. The decline is apparent across all age groups.

Measuring virus transmission levels can be challenging; health officials agree that Covid-19 cases are vastly undercounted, and surveillance systems used for flu and RSV capture a substantial, but incomplete picture.

But experts say that tracking emergency department visits can be a good indicator of how widespread – and severe – the respiratory virus season is.

“There’s the chief complaint. When you show up to the emergency room, you complain about something,” said Janet Hamilton, executive director at Council of State and Territorial Epidemiologists. “Being able to look at the proportion of individuals that seek care at an emergency department for these respiratory illness concerns is a really good measure of the respiratory disease season.”

In the week following Thanksgiving, emergency department visits for respiratory viruses topped 235,000 – matching rates from last January, according to the CDC data.

While the surge in emergency department visits early in the year was due almost entirely to Omicron, the most recent spike was much more varied. In the week ending December 3, about two-thirds of visits were for flu, about a quarter were for Covid-19 and about 10% were for RSV.

Grouping the impact of all respiratory viruses together in this way offers an important perspective.

“There’s a strong interest in thinking about respiratory diseases in a more holistic way,” Hamilton said. “Transmission is the same. And there are certain types of measures that are good protection against all respiratory diseases. So that could really help people understand that when we are in high circulation for respiratory diseases, there are steps that you can take – just in general.”

Now, Covid-19 again accounts for most emergency department visits but flu and RSV are still the reason behind about a third of visits – and they’re all trending down for the first time since the respiratory virus season started picking up in September.

More new data from the CDC shows that overall respiratory virus activity continues to decline across the country. Only four states, along with New York City and Washington, DC, had “high” levels of influenza-like illness. Nearly all states were in this category less than a month ago.

Whether that pattern will hold is still up in the air, as vaccination rates for flu and Covid-19 are lagging and respiratory viruses can be quite fickle. Also, while the level of respiratory virus activity is lower than it’s been, it’s still above baseline in most places and hospitals nationwide are still about 80% full.

RSV activity started to pick up in September, reaching a peak in mid-November when 5 out of every 100,000 people – and 13 times as many children younger than five – were hospitalized in a single week.

RSV particularly affects children, and sales for over-the-counter children’s pain- and fever-reducing medication were 65% higher in November than they were a year before, according to the Consumer Healthcare Products Association. While “the worst may be over,” demand is still elevated, CHPA spokesperson Logan Ramsey Tucker told CNN in an email – sales were up 30% year-over-year in December.

But this RSV season has been significantly more severe than recent years, according to CDC data. The weekly RSV hospitalization rate has dropped to about a fifth of what it was two months ago, but it is still higher than it’s been in previous seasons.

Flu activity ramped up earlier than typical, but seems to have already reached a peak. Flu hospitalizations – about 6,000 new admissions last week – have dropped to a quarter of what they were at their peak a month and a half ago, and CDC estimates for total illnesses, hospitalizations and deaths from flu so far this season have stayed within the bounds of what can be expected. It appears the US has avoided the post-holiday spike that some experts cautioned against, but the flu is notoriously unpredictable and it’s not uncommon to see a second bump later in season.

The Covid-19 spike has not been as pronounced as flu, but hospitalizations did surpass levels from the summer. However, the rise in hospitalizations that started in November has started to tick down in recent weeks and CDC data shows that the share of the population living in a county with a “high” Covid-19 community level has dropped from 22% to about 6% over the past two weeks.

Still, the XBB.1.5 variant – which has key mutations that experts believe may be helping it to be more infectious – continues to gain ground in the US, causing about half of all infections last week. Vaccination rates continue to lag, with just 15% of the eligible population getting their updated booster and nearly one in five people remain completely unvaccinated.

Ensemble forecasts published by the CDC are hazy, predicting a “stable or uncertain trend” in Covid-19 hospitalizations and deaths over the next month.

And three years after the first Covid-19 case was confirmed in the US, the virus has not settled into a predictable pattern, according to Dr. Maria Van Kerkhove, the World Health Organization’s technical lead for the Covid-19 response.

“We didn’t need to have this level of death and devastation, but we’re dealing with it, and we are doing our best to minimize the impact going forward,” Van Kerkhove told the Conversations on Healthcare podcast this week.

Van Kerkhove says she does believe 2023 could be the year in which Covid-19 would no longer be deemed a public health emergency in the US and across the world, but more work needs to be done in order to make that happen and transitioning to longer-term respiratory disease management of the outbreak will take more time.

“We’re just not utilizing [vaccines] most effectively around the world. I mean 30% of the world still has not received a single vaccine,” she said. “In every country in the world, including in the US, we’re missing key demographics.”

Decreasing rates of childhood immunization are a major concern. Our medical analyst explains why | CNN



CNN
 — 

Vaccine rates for measles, polio, diphtheria and other diseases are decreasing among US children, according to a new study from the US Centers for Disease Control and Prevention.

The rate of immunizations for required vaccines among kindergarten students declined from 95% to approximately 94% during the 2020-21 school year. It dropped further — to 93% — in the 2021-22 school year.

That’s still a high number, so why is this drop in immunization significant? What accounts for the decline? What might be the consequences if these numbers drop further? If parents are unsure about vaccinating their kids, what should they do? And what can be done on a policy level to increase immunization numbers?

To help us with these questions, I spoke with CNN Medical Analyst Dr. Leana Wen, an emergency physician, public health expert and professor of health policy and management at the George Washington University Milken Institute School of Public Health. She is also author of “Lifelines: A Doctor’s Journey in the Fight for Public Health.”

CNN: Why is it a problem that childhood immunization rates are declining?

Dr. Leana Wen: The reduction of vaccine-preventable diseases is one of the greatest public health success stories in the last 100 years.

The polio vaccine was introduced in the United States in 1955, for example. In the four years prior, there were an average of over 16,000 cases of paralytic polio and nearly 2,000 deaths from polio each year across the US. Widespread use of the polio vaccine had led to the eradication of polio in the country by 1979, according to the CDC, sparing thousands of deaths and lifelong disability among children each year.

The measles vaccine was licensed in the US in 1963. In the four years before that, there were an average of over 500,000 cases and over 430 measles-associated deaths each year. By 1998, there were just 89 cases recorded — and no measles-associated deaths.

These vaccines are very safe and extremely effective. The polio vaccine, for example, is over 99% effective at preventing paralytic polio. The measles vaccine is 97% effective at preventing infection.

We can do this same analysis for other diseases for which there are routine childhood immunizations.

It’s very concerning that rates of immunization are declining for vaccines that have long been used to prevent disease and reduce death. That means more children are at risk for severe illness — illness that could be averted if they were immunized. Moreover, if the proportion of unvaccinated individuals increases in a community, this also puts others at risk. That includes babies too young to be vaccinated or people for whom the vaccines don’t protect as well — for example, patients on chemotherapy for cancer.

CNN: What accounts for the decline in vaccination numbers?

Wen: There are probably many factors. First, there has been substantial disruption to the US health care system during the Covid-19 pandemic. Many children missed routine visits to the pediatrician during which they would have received vaccines due to pandemic restrictions. In addition, some community health services offered also became disrupted as local health departments focused on Covid-19 services.

Second, disruption to schooling has also played a role. Vaccination requirements are often checked prior to the start of the school year. When schools stopped in-person instruction, that led to some families falling behind on their immunizations.

Third, misinformation and disinformation around Covid-19 vaccines may have seeded doubt in other vaccines. Vaccine hesitancy and misinformation were already major public health concerns before the coronavirus emerged, but the pandemic has exacerbated the issues.

According to a December survey published by the Kaiser Family Foundation, more than one in three American parents said vaccinating children against measles, mumps, and rubella shouldn’t be a requirement for them to attend public schools, even if that may create health risks for others. This was a substantial increase from 2019, when a similar poll from the Pew Research Center found only 23% of parents opposed school vaccine requirements.

CNN: What are some consequences if immunization rates drop further?

Wen: If immunization rates drop further, we could see more widespread outbreaks. Diseases that were virtually eliminated in the US could reemerge, and more people can become severely ill and suffer lasting consequences or even die.

We are already seeing some consequences: Last summer, there was a confirmed case of paralytic polio in an unvaccinated adult in New York. It’s devastating that a disease like polio has been identified again in the US, since we have an extremely effective vaccine to prevent it.

There is an active measles outbreak in Ohio. As of January 17, 85 cases have been reported. Most of the cases involved unvaccinated children, and at least 34 have been hospitalized.

CNN: If parents are unsure of vaccinating their kids, what should they do?

Wen: As parents, we generally trust pediatricians with our children’s health. We consult pediatricians if our kids are diagnosed with asthma and diabetes, or if they have new worrisome symptoms of another illness. We should also consult our pediatricians about childhood immunizations; parents and caregivers with specific questions or concerns should address them.

The national association of pediatricians, the American Academy of Pediatrics, “strongly recommends on-time routine immunization of all children and adolescents according to the Recommended Immunization Schedules for Children and Adolescents.”

CNN: What can be done to increase immunization numbers?

Wen: There needs to be a concerted educational campaign to address why vaccination against measles, mumps, rubella, chickenpox, polio and so forth is so crucial. One of the reasons for vaccine hesitancy, in my experience, is that these diseases have been rarely seen in recent years. Many people who are parents now didn’t experience the devastation of these diseases growing up, so may not realize how terrible it would be for them to return.

Specific interventions should be targeted at the community level. In some places, low immunization levels may be due to access. Vaccination drives at schools, parks, shopping centers, and other places where families gather can help increase numbers. In other places, the low uptake may be because of vaccine hesitancy and misinformation. There will need to be different strategies implemented in that situation.

Overall, increasing immunization rates for vaccine-preventable childhood diseases needs to be a national imperative. I can’t underscore how tragic it would be for kids to suffer the harms of diseases that could be entirely prevented with safe, effective and readily available vaccines that have been routinely given for decades.
