Here’s a look at Ebola, a virus with a high fatality rate that was first identified in Africa in 1976.

Ebola hemorrhagic fever is a disease caused by one of five different Ebola viruses. Four of the strains can cause severe illness in humans and animals. The fifth, Reston virus, has caused illness in some animals, but not in humans.

The first human outbreaks occurred in 1976, one in northern Zaire (now Democratic Republic of the Congo) in central Africa: and the other, in southern Sudan (now South Sudan). The virus is named after the Ebola River, where the virus was first recognized in 1976, according to the Centers for Disease Control and Prevention (CDC).

Ebola is extremely infectious but not extremely contagious. It is infectious, because an infinitesimally small amount can cause illness. Laboratory experiments on nonhuman primates suggest that even a single virus may be enough to trigger a fatal infection.

Ebola is considered moderately contagious because the virus is not transmitted through the air.

Humans can be infected by other humans if they come in contact with body fluids from an infected person or contaminated objects from infected persons. Humans can also be exposed to the virus, for example, by butchering infected animals.

Symptoms of Ebola typically include: weakness, fever, aches, diarrhea, vomiting and stomach pain. Additional experiences include rash, red eyes, chest pain, throat soreness, difficulty breathing or swallowing and bleeding (including internal).

Typically, symptoms appear eight to 10 days after exposure to the virus, but the incubation period can span two to 21 days.

Ebola is not transmissible if someone is asymptomatic and usually not after someone has recovered from it. However, the virus has been found in the semen of men who have recovered from Ebola and possibly could be transmitted from contact with that semen.

There are five subspecies of the Ebola virus: Zaire ebolavirus (EBOV), Bundibugyo ebolavirus (BDBV), Sudan ebolavirus (SUDV), Taï Forest ebolavirus (TAFV) and Reston ebolavirus (RESTV).

September 16, 2014 – US President Barack Obama calls the efforts to combat the Ebola outbreak centered in West Africa “the largest international response in the history of the CDC.” Speaking from the CDC headquarters in Atlanta, Obama adds that “faced with this outbreak, the world is looking to” the United States to lead international efforts to combat the virus.

October 6, 2014 – A nurse’s assistant in Spain becomes the first person known to have contracted Ebola outside Africa in the current outbreak. The woman helped treat two Spanish missionaries, both of whom had contracted Ebola in West Africa, one in Liberia and the other in Sierra Leone. Both died after returning to Spain. On October 19, Spain’s Special Ebola Committee says that nurse’s aide Teresa Romero Ramos is considered free of the Ebola virus.

A total of 3,481 cases were reported, including 2,299 deaths and 1,162 survivors.

August 12, 2019 – Two new Ebola treatments are proving so effective they are being offered to all patients in the DRC. Initial results found that 499 patients who received the two effective drugs had a higher chance of survival – the mortality rate for REGN-EB3 and mAb114 was 29% and 34% respectively. The two drugs worked even better for patients who were treated early – the mortality rate dropped to 6% for REGN-EB3 and 11% for mAb114, according to Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases and one of the researchers leading the trial.

December 19, 2019 – The US Food and Drug administration announces the approval of a vaccine for the prevention of the Ebola virus for the first time in the United States.

Here is a look at autism.

Autism or autism spectrum disorder (ASD) incorporates a group of neurodevelopmental disorders causing impaired communication skills and social skills. ASD generally starts before three years of age and lasts a lifetime, but early intervention plays a role in treatment and progress.

ASD is about four times more common among boys than girls, according to the Centers for Disease Control and Prevention (CDC).

ASD can be found among all races, ethnicities and socioeconomic groups.

The prevalence of ASD in the United States is about one in 36 8-year-olds, according to a 2023 CDC report.

Health care costs for children with autism are four to six times greater than medical costs for children without autism, according to research published in the Journal of Autism and Developmental Disorders.

April 2 is World Autism Day.

There is no definitive medical test to diagnose autism. Instead, the disorder is diagnosed by observing a child’s development.

According to the CDC, signs of autism may include deficits in social communication and interaction in a variety of contexts, difficulty engaging in back-and-forth conversation and an absence of interest in forming friendships with peers.

The debate over whether autism spectrum disorders are caused by vaccines started in 1998 when the medical journal The Lancet published a now-retracted study by researcher Andrew Wakefield linking the MMR vaccine to autism.

Most of Wakefield’s co-authors withdrew their names from the study when they learned he had been compensated by a law firm intending to sue manufacturers of the vaccine in question. In 2010, Wakefield lost his medical license. In 2011, the Lancet retracted the study after an investigation found Wakefield altered or misrepresented information on the 12 children who were the basis for the conclusion of the study.

Other researchers have not been able to replicate Wakefield’s findings. Several subsequent studies trying to reproduce the results have found no link between vaccines and autism, including several reviews by the Institute of Medicine.

Early 1900s – Autistic characteristics are studied as symptoms of schizophrenia.

1938 – Donald Gray Triplett of Mississippi is first examined by child psychiatrist Leo Kanner of Johns Hopkins Hospital and later becomes the first person diagnosed with autism symptoms.

1943 – Triplett is identified as “Donald T.” in the paper “Autistic Disturbances of Affective Contact” by Kanner. The paper elaborates on the idea that autism is related to lack of parental warmth; this is later dubbed the “refrigerator mother” theory.

1944 – Hans Asperger, an Austrian physician, publishes a paper about autistic syndrome. The paper gains wider recognition when it is translated into English in the early 1990s.

1964 – Bernard Rimland, a research psychologist, publishes “Infantile Autism: The Syndrome and Its Implications for a Neural Theory of Behavior,” which contradicts the “refrigerator mother” hypothesis. Kanner is the author of the foreword.

1965 – Rimland founds the National Society for Autistic Children (now the Autism Society). He later establishes the Autism Research Institute.

1980 – Autism is classified separately from schizophrenia in the third edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III).

December 18, 2007 – The United Nations adopts a resolution declaring April 2 World Autism Awareness Day.

October 29, 2014 – The medical journal Nature reports that scientists have identified 60 genes with a greater than 90% chance of increasing a child’s autism risk.

December 17, 2015 – Scientists at Harvard and MIT announce they have found, for the first time, a link between autistic behavior and reduced activity of a key neurotransmitter, a type of brain chemical that enables the transmission of signals across neurons, allowing the brain to communicate with other organs.

April 21, 2016 – The Simons Foundation announces that it is launching an autism research project called SPARK. The study, which involves scientists at 21 hospitals and university clinics, will focus on the possible connection between genetics and autism. Parents of children with autism are invited to sign up online and participate in the study. The group also works with Autism Speaks and the Autism Science Foundation to run the Autism BrainNet network, which is an autism brain bank that collects postmortem donations.

February 2017 – Researchers find that monitoring MRI brain scans of infants may help predict whether they will develop autism, according to a study published in the journal, Nature. The researchers found a possible link between brain enlargement during the first year of life and an autism diagnosis at age 2. This builds on previous similar research.

March 19, 2017 – CBS News’ “60 Minutes” profiles “Sesame Street’s” newest Muppet character, a girl named Julia who has autism.

April 11, 2017 – A study published in the American Journal of Public Health finds that people with autism are three times more likely than the general population to die because of preventable injuries, and children and young teens with autism are 40 times more likely to die from preventable injury than the general child population. Suffocation, asphyxiation and drowning are the leading causes of fatal injuries among people with autism.

March 26, 2018 – According to a study published in JAMA Pediatrics, children with autism spectrum disorder and their younger siblings are less likely to be fully vaccinated than children unaffected by autism.

March 4, 2019 – A study of over 650,000 children published in the journal Annals of Internal Medicine shows that the measles, mumps, and rubella vaccine does not increase the risk of autism and does not trigger autism in children who are at risk.

April 29, 2019 – A study published in JAMA Pediatrics suggests that children can be screened for autism spectrum disorder at 14 months of age with high accuracy (instead of 18 to 24 months of age, as is currently recommended).

January 23, 2020 – A study in the journal Cell identifies 102 genes that are associated with an autism risk. Previously, researchers were only aware of 65.

May 10, 2020 – In a report published in the Journal of Autism and Developmental Disorders, the CDC estimates that 2.2% of Americans adults have autism spectrum disorder. The report, which is the first US study of autism in adults, indicates that up to 5.4 million people age 18 and older, or about 1 in 45 people, have an autism spectrum condition.

February 14, 2022 – A meta-analysis published in JAMA Pediatrics finds that early mortality, due to natural or unnatural causes, is more than two times more likely for people with autism spectrum disorder than the general population.

Here’s a look at information and statistics concerning vaccines in the United States. For vaccines related to coronavirus, see Coronavirus Outbreak Timeline Fast Facts.

The Centers for Disease Control and Prevention (CDC) provides vaccine recommendations by age, as well as by disease.

For more than 100 years, there has been public discord regarding vaccines based on issues like individual rights, religious freedoms, distrust of government and the effects that vaccines may have on the health of children.

Exemptions to vaccines fall into three general categories: medical, religious and philosophical.

As of May 25, 2022, 44 states and the District of Columbia have enacted legislation allowing religious exemptions from vaccines, and 15 states allow philosophical (non-spiritual) exemptions.

1796 – Edward Jenner develops the smallpox vaccine, the world’s first successful vaccine.

1855 – Massachusetts mandates that school children are to be vaccinated (only the smallpox vaccine is available at the time).

February 20, 1905 – In Jacobson v. Massachusetts, the US Supreme Court upholds the State’s right to compel immunizing against smallpox.

November 13, 1922 – The US Supreme Court denies any constitutional violation in Zucht v. King in which Rosalyn Zucht believes that requiring vaccines violates her right to liberty without due process. The High Court opines that city ordinances that require vaccinations for children to attend school are a “discretion required for the protection of the public health.”

1952 – Dr. Jonas Salk and his team develop a vaccine for polio. A nationwide trial leads to the vaccine being declared in 1955 to be safe and effective.

1963 – The first measles vaccine is released. In 2000, the CDC declares the US has achieved measles elimination, defined as “the absence of continuous disease transmission for 12 months or more in a specific geographic area.” While the US has maintained measles elimination since, there are occasional outbreaks.

1986 – Congress passes the National Childhood Vaccine Injury Act. This coordinates vaccine activities across several government agencies to monitor vaccine safety, requires vaccine information statements are provided to those receiving vaccines, and creates the National Vaccine Injury Compensation Program to compensate those injured by vaccines on a “no fault” basis.

March 19, 1992 – Rolling Stone publishes an article by Tom Curtis, “The Origin of AIDS,” which presents a theory that ties HIV/AIDS to polio vaccines. Curtis writes that in the late 1950s, during a vaccination campaign in Africa, at least 325,000 people were immunized with a contaminated polio vaccine. The article alleges that the vaccine may have been contaminated with a monkey virus and is the cause of the human immunodeficiency virus, later known as HIV/AIDS.

August 10, 1993 – Congress passes the Omnibus Budget Reconciliation Act which creates the Vaccines for Children Program, providing qualified children free vaccines.

December 9, 1993 – Rolling Stone publishes an update to the Curtis article, clarifying that his theory was not fact, and Rolling Stone did not mean to suggest there was any scientific proof to support it, and the magazine regrets any damage caused by the article.

1998 – British researcher Andrew Wakefield and 12 other authors publish a paper stating they had evidence that linked the vaccination for Measles, Mumps and Rubella (MMR) to autism. They claim they discovered the measles virus in the digestive systems of autistic children who were given the measles, mumps and rubella (MMR) vaccine. The publication leads to a widespread increase in the number of parents choosing not to vaccinate their children for fear of its link to autism.

2004 – Co-authors of the Wakefield study begin removing their names from the article when they discover Wakefield had been paid by lawyers representing parents who planned to sue vaccine manufacturers.

May 14, 2004 – The Institute of Medicine releases a report “rejecting a causal relationship between the MMR vaccine and autism.”

February 2010 – The Lancet, the British medical journal that published Wakefield’s study, officially retracts the article. Britain also revokes Wakefield’s medical license.

2011 – Investigative reporter Brian Deer writes a series of articles in the BMJ exposing Wakefield’s fraud. The articles state that he used distorted data and falsified medical histories of children that may have led to an unfounded relationship between vaccines and the development of autism.

2011 – The US Public Health Service finds that 63% of parents who refuse and delay vaccines do so for fear their children could have serious side effects.

June 17, 2014 – After analyzing 10 studies, all of which looked at whether there was a link between vaccines and autism and involved a total of over one million children, the University of Sydney publishes a report saying there is no correlation between vaccinations and the development of autism.

February 2015 – Advocacy group Autism Speaks releases a statement, “Over the last two decades, extensive research has asked whether there is any link between childhood vaccinations and autism. The results of this research are clear: Vaccines do not cause autism. We urge that all children be fully vaccinated.

August 23, 2018 – A study published in the American Journal of Public Health finds that Twitter accounts run by automated bots and Russian trolls masqueraded as legitimate users engaging in online vaccine debates. The bots and trolls posted a variety of anti-, pro- and neutral tweets and directly confronted vaccine skeptics, which “legitimize” the vaccine debate, according to the researchers.

October 11, 2018 – Two reports published by the CDC find that vaccine exemption rates and the percentage of unvaccinated children are on the rise.

January 2019 – The World Health Organization names vaccine hesitancy as one of 10 threats to global health in 2019.

September 4, 2019 – Facebook announces that educational pop-up windows will appear on the social media platforms when a user searches for vaccine-related content, visits vaccine-related Facebook groups and pages, or taps a vaccine-related hashtag on Instagram

December 27, 2019 – A study published in the medical journal JAMA Network Open finds that a single dose of the human papillomavirus (HPV) vaccine may be just as effective as two or three doses at preventing cancer-causing HPV infection.

February 3, 2020 – The National Institute of Allergy and Infectious Diseases (NIAID) announces that a clinical trial for an HIV vaccine has been discontinued since the vaccine was not found to prevent infections of human immunodeficiency virus, the virus that causes AIDS.

May 3, 2023 – The US FDA approves, Arexvy, the first vaccine to protect against respiratory syncytial virus or RSV. It is a single shot for adults 60 or older.

Here’s a look at mpox, formerly known as monkeypox, in the United States. In 2022, an outbreak was declared a public health emergency of international concern by the World Health Organization (WHO). The virus originated in Africa and is the cousin of the smallpox virus.

In November 2022, WHO renames the monkeypox virus as mpox after working with International Committee on the Taxonomy of Viruses (ICTV) to rename the the virus using non-stigmatizing, non-offensive social and cultural nomenclature.

(Source: Centers for Disease Control and Prevention)

Mpox is a poxvirus. It generally causes pimple- or blister-like lesions and flu-like symptoms such as fever. The disease is rarely fatal.

Mpox spreads through close contact. This includes direct physical contact with lesions as well as “respiratory secretions” shared through face-to-face interaction and touching objects that have been contaminated by mpox lesions or fluids. The virus may also pass to a fetus through the placenta.

Anyone can become ill from mpox, but the US Centers for Disease Control and Prevention (CDC) says that more than 99% of mpox cases in the United States in the 2022 outbreak have been among men who have sex with men. However, mpox is not generally considered a sexually transmitted disease.

Mpox is usually found in West and Central Africa, but additional cases have been seen in Europe, including the United Kingdom, and other parts of the world in recent years. Those cases are typically linked to international travel or imported animals infected with the poxvirus.

CDC Mpox Map and Case Count

WHO Situation Reports

1958 – Mpox is discovered when monkeys kept for research cause two outbreaks in Copenhagen, Denmark.

1970 – The first human case is recorded in Zaire (now the Democratic Republic of Congo).

2003 – An outbreak in the United States is linked to infected pet prairie dogs imported from Ghana and results in more than 80 cases.

July 16, 2021 – The CDC and local health officials in Dallas announce they are investigating a case of mpox in a traveler from Nigeria. “The individual is a City of Dallas resident who traveled from Nigeria to Dallas, arriving at Love Field airport on July 9, 2021. The person is hospitalized in Dallas and is in stable condition,” the Dallas County Department of Health and Human Services says in a statement.

May 17, 2022 – The first confirmed US case of mpox in the 2022 outbreak is reported to the CDC in a traveler who returned to Massachusetts from Canada.

May 19, 2022 – WHO reports that death rates of the outbreak have been between 3% and 6%.

May 23, 2022 – The CDC announces the release of mpox vaccine doses from the nation’s Strategic National Stockpile for “high-risk people.” In the United States, the two-dose Jynneos vaccine is licensed to prevent smallpox and specifically to prevent mpox.

May 26, 2022 – CDC Director Dr. Rochelle Walensky announces that the United States is distributing the vaccine to states with reported cases and recommends vaccination for people at highest risk of infection due to direct contact with someone who has mpox.

June 22, 2022 – The CDC announces a partnership with five commercial laboratories to ramp up testing capacity in the United States.

June 23, 2022 – New York City launches the first mpox vaccination clinic in the United States.

June 28, 2022 – The US Department of Health and Human Services (HHS) and the Biden administration announce an enhanced vaccination strategy and report that more than 9,000 doses of vaccine have been distributed to date.

July 22, 2022 – Two American children contract mpox – a first in the United States. According to the CDC, the two cases are unrelated.

July 23, 2022 – WHO declares mpox a public health emergency of international concern, “an extraordinary event that may constitute a public health risk to other countries through international spread of disease and may require an international coordinated response.”

July 27, 2022 – After weeks of mpox vaccines being in limited supply, more than 786,000 additional doses are made available in the United States, according to HHS.

July 29, 2022 – New York declares a state disaster emergency in response to the mpox outbreak.

August 1, 2022 – California and Illinois declare states of emergency. California has reported more than 800 cases, while Illinois has had more than 500, according to data from the CDC.

August 2, 2022 – An mpox response team is created by the Biden administration. President Joe Biden names Robert Fenton from the Federal Emergency Management Agency (FEMA) as the White House national mpox response coordinator.

August 2, 2022 – A report from Spain’s National Institute for Microbiology indicates two men, ages 31 and 44, who died from mpox in unrelated cases had both developed encephalitis, or swelling of the brain, which can be triggered by viral infections. Encephalitis is a very rare condition known to be associated with mpox. It has been reported in people with mpox in West Africa and in a patient in the United States in 2003 during the small outbreak linked to imported prairie dogs.

August 4, 2022 – The Biden administration declares the mpox outbreak a national public health emergency.

August 5, 2022 – A report published by the CDC finds that 94% of cases were among men who had recent sexual or close intimate contact with another man. Further, 54% of cases were among Black Americans and Latinos.

August 9, 2022 – In an effort to stretch the limited supply of the Jynneos mpox vaccine, federal health officials authorize administering smaller doses using a different method of injection. The new injection strategy allows health-care providers to give shallow injections intradermally, in between layers of the skin, with one-fifth the standard dose size instead of subcutaneously, into the fatty layer below the skin, with the larger dose.

August 18, 2022 – The White House announces the acceleration of the HHS vaccine distribution timeline, with an additional 1.8 million doses of the Jynneos vaccine being made available. Additional vaccines will be distributed to communities hosting large LGBTQI+ events.

Here’s a look at the coronavirus outbreak, declared a worldwide pandemic by the World Health Organization. The coronavirus, called Covid-19 by WHO, originated in China and is the cousin of the SARS virus.

Coronaviruses are a large group of viruses that are common among animals. The viruses can make people sick, usually with a mild to moderate upper respiratory tract illness, similar to a common cold. Coronavirus symptoms include a runny nose, cough, sore throat, possibly a headache and maybe a fever, which can last for a couple of days.

—

When the US public health emergency ends May 11, the US Centers for Disease Control and Prevention will have to change some of the ways it tracks Covid-19 in the United States, but the agency says it won’t lose its sightlines on the infection as it continues to be part of American life.

On Thursday, for the first time in three years, the CDC will stop posting a national count of Covid-19 cases. The agency’s color-coded maps of county-level transmission and disease burden will be retired, the CDC will no longer track variants down to the state level, and it will update its genomic surveillance estimates every two weeks instead of weekly.

“Though our data going forward will be different, they will continue to provide timely insights for CDC, for local health officials, as well as for the public to understand Covid-19 dynamics,” CDC Principal Deputy Director Dr. Nirav Shah said.

“In short, we will still be able to tell that it’s snowing, even though we’re no longer counting every snowflake.”

Instead of following Covid-19 cases, the agency will track the burden and spread of disease primarily through hospitalizations and deaths.

The move to stop posting a national case count is largely symbolic. The number of Covid-19 cases known to public health officials has long been undercounted. The percent of detected cases has only fallen further as people have turned to rapid home testing for a diagnosis. At some points in the pandemic, experts estimated that the true number of cases was more than 14 times higher than official counts.

Other metrics that people are used to seeing on the CDC’s Covid Data Tracker are also going to go away. As CNN previously reported, the CDC will stop publishing detailed, color-coded Covid-19 Transmission Levels and Covid-19 Community Level maps that have been tied to recommendations about when to wear masks, when it’s a good idea for people to test to prevent the spread of disease and when to avoid large indoor public gatherings.

When the public health emergency ends, more states are expected to stop reporting Covid-19 cases to CDC. Iowa, for example, has already stopped. So the CDC says it won’t be feasible to maintain a national count or update its maps.

Future recommendations for precautions like masking will instead be tied to hospitalization levels.

Covid-19 will retain its designation as a nationally notifiable disease, but that’s just a recommendation, says Dr. Brendan Jackson, who leads the CDC’s Covid-19 response. It doesn’t carry any authority for required reporting. When the public health emergency ends, it will be a state-by-state decision whether to share those numbers, Jackson said Thursday.

The CDC says it will still publish the case counts it gets from states, but that will be in a different section of its website, and the numbers won’t be totaled.

Some experts say they’re disappointed to see that the CDC will have to go back to an older, fragmented system of having to ask states to share data.

“We’re kind of reverting back to a system where the CDC kind of independently negotiates all these data sharing agreements with the states and they make it more voluntary,” said Beth Blauer, associate vice provost for public sector innovation at Johns Hopkins University.

“I think having the states do this all independently doesn’t make a ton of sense because it doesn’t help us understand, in the aggregate, the impact that disease is having on our communities,” Blauer said.

She also said it will be very difficult to scale this system back up should another large, immediate public health threat emerge.

Starting next week, vaccination counts will become discretionary. Jackson said that most, but not all, of the 64 jurisdictions that report to the CDC have signed data use agreements to share their vaccine administration numbers. They may not share as much as they have in the past about who is getting vaccinated or do it as frequently, which may limit the nation’s ability to spot widespread racial, ethnic or socioeconomic disparities for future vaccination campaigns. Starting in June, the CDC says, it will update its vaccination data on a monthly basis.

Laboratories will no longer be required to send testing data to the CDC, which will hamper the ability to understand test positivity rates, a metric that, early in the pandemic, helped public health officials know whether they were doing enough testing or if transmission in a community was going up or down. Positivity rates were used in the transmission maps but also for the CDC’s tracking of variants.

The CDC will still get some lab testing data from another system called the National Respiratory and Enteric Virus Surveillance System, a network of about 450 labs that help it track illnesses like influenza and respiratory syncytial virus, or RSV.

Variant tracking will continue, but the CDC will have to adjust some of the metrics it uses to model variant proportions. State-level estimates of variant proportions with go away, but regional levels will remain. Those will be updated twice a month going forward instead of weekly, as they are now.

The way the CDC will collect data on deaths will change, too. Instead of scraping numbers from state website and getting direct reports from states, which counted deaths based on the date they were reported, the CDC will switch to a national system that counts deaths based on death certificate data. The agency says this system has become much more timely and will be a more stable way to count Covid-19 deaths going forward. It will also add a new metric to its death reporting: the percentage of all deaths reported that week that are caused by Covid-19.

Hospitals will still have to report Covid-19 data through April 2024, but they won’t track as many metrics or submit that information as frequently. Hospitals have shared information daily through most of the pandemic, but now that reporting will be weekly.

Hospitalizations and deaths are known as lagging indicators because they increase only after people have gotten sick. Studies released Friday from CDC epidemiologists show that hospitalizations may not lag behind cases as much as we once thought they did.

The new studies, published in the CDC’s Morbidity and Mortality Weekly Report, show that Covid-19 hospitalizations lagged one day behind increases in reported cases and four days behind increases in emergency room visits.

The research also shows that the new system the CDC will be using to track deaths will show trends 13 days earlier than data collected from states, the system that’s being discontinued.

With case levels low across most of the country, the need for these kinds of insights has gone away, or scientists have found other ways to get the information, such as testing of wastewater, which begins to increase about a week before testing data reflects an uptick in spread. Wastewater testing is available in some places, but not all areas have this capability.

The CDC will also maintain traveler surveillance, testing wastewater on airplanes in an effort to spot new incoming threats.

The CDC will also maintain what it calls sentinel systems: smaller, but nationally representative networks of hospitals and laboratories that will feed in more detailed data. This is much the same way the agency tracks patterns in other respiratory diseases, such as the flu and RSV. The CDC says recent investments in these sentinel systems will help it maintain eyes on Covid-19.

Instead, it will be using hospitalizations and emergency room visits as the primary ways it tracks Covid-19 and as the basis for its recommendations. When hospitalization rates in an area are high, for example, it will be recommending that people wear masks, said Jackson.

CDC Director Dr. Rochelle Walensky acknowledged some of these data changes in a Senate committee hearing this week, although she emphasized that the CDC was not “changing the steam” of its work on Covid-19.

“As the public health emergency is set to end next week, I do want to just reiterate that we at CDC are not changing the steam at which we are working through resolving this public health emergency,” Walensky said at a hearing of the Senate Committee on Health Education, Labor and Pensions.

“It is the case at the end of the public health emergency, we will have less window as to the data,” she said. “We won’t get laboratory reporting. We won’t get case reporting. So we’ll lose some of that.”

US government is testing avian flu vaccines for birds, but ending the historic outbreak isn’t that simple | CNN

The United States is facing what some experts are calling “a new era for bird flu.”

Since January 2022, the country has been battling the biggest outbreak yet of highly pathogenic avian influenza in wildlife. The virus is a major threat to commercial and backyard flocks, and it has started to show up in hundreds of mammals, including a handful of pet cats.

The risk to humans is low; there has been only one human case of this virus in the US since the outbreak began, according to the US Centers for Disease Control and Prevention, and nine cases globally, mostly among people who work with birds. The CDC says there are trials underway of vaccines that could be used to protect humans in case the virus changes and becomes more of a threat.

Separately, the US Department of Agriculture, the US National Poultry Research Center and labs at a handful of American universities have been experimenting with vaccine candidates to be used in birds.

The USDA’s Agriculture Research Service started trials of four vaccine candidates for animals in April and expects to have initial data on a single-dose vaccine available this month. A two-dose vaccine challenge study – in which animals are exposed to the virus to see how well the vaccine works – should produce results in June.

If the animal vaccines look to be protective, the USDA’s next step would be to work with manufacturers on whether it would be feasible to use them.

One manufacturer, Zoetis, announced April 5 the development of a vaccine geared toward currently circulating virus strains. The company says it would take about a year to get to the distribution stage in the US.

Vaccines are already available in other countries, including China, Egypt, Indonesia, Italy, Mexico and Vietnam, and some nations are vaccinating their commercial flocks.

However, in the United States, not all poultry experts are ready to use a vaccine, even if one becomes available – at least, not yet. Instead, their focus remains on eradicating the virus.

As of April 26, the CDC says, nearly 58.8 million poultry have been affected by avian flu since January 2022. The virus has been detected in at least 6,737 wild birds, and the number is likely to be much higher. There have been poultry outbreaks in 47 states.

Although this is the worst outbreak in history, improved biosecurity measures have vastly reduced the number of cases in the commercial sector, according to the USDA. When the outbreak began in early 2022, there were 51 detections among commercial poultry. In March 2023, there were only seven.

The USDA says close surveillance work among its Animal and Plant Health Inspection Service (APHIS) and state and industry partners led to the reduction in cases.

Generally, there ares two ways of confronting this kind of highly infectious disease in poultry, according to Rodrigo Gallardo, a professor in poultry medicine and a specialist in avian virology at the University of California, Davis.

“One of them is through vaccination action. And then the other one is through eradication,” he said.

In the United States, the latter is the approach for now, Gallardo said.

If farmers detect even a single case in a flock, they will put down the birds right away.

“The virus keeps replicating and amplifying if the birds are alive, so the only way of stopping the replication and limiting the dissemination is by depopulation,” Gallardo said.

Tom Super, the senior vice president for communications for the National Chicken Council, the national trade association for the US broiler chicken industry, said in an email to CNN that although it supports the ongoing discussions about a vaccination program, “currently we support the eradication policy of APHIS and believe that right now this is the best approach at eliminating [bird flu] in the U.S.”

The US Poultry and Egg Association said it’s “certainly a topic of discussion,” but the organization doesn’t have a position on implementing a vaccination program.

A vaccination program comes with several complications, Gallardo said. Vaccinated birds would be protected, but with this highly infectious disease, they still could shed some virus that could infect unprotected birds.

“So vaccination, in that case, creates amplification if it is not done right,” Gallardo said.

Plus, it’s difficult to detect the disease in vaccinated birds. Birds that are vaccinated don’t always show signs if they’re sick, so it would be hard to know what birds to keep separate from the others. Tests also have a hard time telling the difference between antibodies generated by vaccination and antibodies from an infection.

“If you’re not able to diagnose it, it might spread more than what it would do if you are able to diagnose it and eradicate it,” Gallardo said.

Countries that have chosen the vaccination route see more endemic strains develop, meaning the virus is never really totally wiped out.

“This is a very variable virus, and if you don’t update the vaccine that you’re applying to meet the change in the virus, then you won’t be able to completely protect the birds. Partial protection means more birds will be spreading the virus,” Gallardo said.

A vaccine has never been used against highly pathogenic avian influenza in the US, according to the USDA. The agency created a vaccine after an outbreak in 2014 and 2015, but that involved a different strain, so it wouldn’t work on the latest version of the virus.

The logistics of a vaccine like this are difficult, said Dr. Yuko Sato, an associate professor in the College of Veterinary Medicine at Iowa State University.

“You have to make sure that the new vaccine will protect against this current virus and hope that it doesn’t mutate or change so that the vaccine will continue to be protective,” Sato said.

“The vaccine is not a silver bullet. This is not going to prevent infection of the birds, so in order to have an exit strategy as the country, you would have to make sure that if you vaccinate, if you still have positive birds, you have to be able to make sure that you could stamp out the virus. Otherwise, we’ll never be looking at eradicating the virus from the United States.”

Another concern: Birds are a big business in the US.

The US has the largest poultry industry in the world, with 294,000 poultry farms. The market size for chicken and turkey meat production alone for 2023 is projected to generate $57.8 billion, according to market analysis firm IbisWorld.

Bird flu has hurt business in the US, but it could do so in a bigger way if the nation vaccinates poultry, according to the National Chicken Council.

“The National Chicken Council does not support the use of a vaccine for [bird flu] for a variety of reasons – the primary one being trade. Most countries, including the US, do not recognize countries that vaccinate as free of [bird flu] due to concerns that vaccines can mask the presence of the disease. Therefore, they do not accept exports from countries that do vaccinate,” Super wrote in his email.

The US broiler industry is the second largest exporter of chicken in the world. It exports about 18% of the chicken meat produced in the United States, valued at more than $5 billion annually.

“If we start vaccinating for [bird flu] in the U.S., the broiler industry will lose our ability to export which will have a significant impact on the industry – while costing billions and billions of dollars to the U.S. economy every year,” Super said.

With the way the disease is spreading, scientists would also probably have to vaccinate wildlife – which is nearly impossible.

Of the birds affected in this outbreak, about 76% are commercial egg-laying hens, 17% are turkeys, and only 5% are broilers, the chickens used for meat, Super said. The rest of the cases have been among ducks, backyard chickens and game birds.

“So the U.S. poultry sector that least needs a vaccine would have the most to risk from using one,” he said.

Texas abortion drug ruling could create ‘slippery slope’ for FDA approvals, drug research and patients, experts say | CNN

What happened in one judge’s courtroom in Texas could have drastic effects for the United States’ entire drug approval process, experts warn.

US District Judge Matthew Kacsmaryk’s ruling that suspended the US Food and Drug Administration’s approval of the medication abortion drug mifepristone was an unprecedented one, the first time a court has bypassed the federal system set up to determine what drugs should be allowed on the market.

Regardless of whether the ruling – or a part of it – is ultimately allowed to stand, legal scholars, scientists and drugmakers are concerned that the decision could start a trend of drugs being targeted in courts, creating a chilling effect on drug development in the US and hurting patients in the process.

Vaccines, including the Covid-19 shots, antidepressants and psychotropic medicines could be at risk, some said.

“Well, one does not want to be Chicken Little,” former FDA Commissioner Dr. Jane Henney said Wednesday, but “I can’t imagine that it wouldn’t have implications for other products.

“The approval process will be at risk, and it’s not just an approval process that patients rely on and providers rely on, it’s one that has been considered the gold standard, really, for the world,” said Henney, who was the head of the FDA when mifepristone was approved.

Since the dawn of the 20th century, the FDA has had the sole authority in the United States to regulate drugs. In 1906, the federal government created the agency to enforce the Pure Food and Drug Act, which was instituted to ensure that medicine, food and cosmetics were safe.

Over the years, that authority became more defined.

After elixir of sulfanilamide, a drug used to treat streptococcal infections, killed 107 people in 1937, Congress created the Food, Drug, and Cosmetic Act. Signed into law in 1938 by President Franklin D. Roosevelt, it required manufacturers to conduct pharmacological studies to prove that their drugs were safe before they could be sold or advertised. In 1962, drug manufacturers were also required to prove to the FDA that their products were effective.

Modern drug approval in the US is a careful and conscientious process. Before any drug goes to market, there are countless hours of research, the work and expertise of multiple scientists, and several layers of oversight for approval.

Until now, the courts have been deferential to the FDA’s process and have never overturned an FDA decision on the grounds that the agency misjudged the science, said William Schultz, a former deputy commissioner at the FDA and former general counsel for the Department of Health and Human Services.

“Any FDA drug approval involves hundreds of judgments by the agency. And if a court feels free just to kind of take a fresh look at each of those, there’s a chance that a court will find one of those FDA judgments wrong,” Schultz said in an online discussion Monday about the impact of the Texas court’s ruling that was hosted by Protect Our Care, an organization that advocates for equitable and affordable health care.

Hundreds of well-known biotech and pharmaceutical company leaders, concerned about the effects of Kacsmaryk’s ruling on other drug approvals, signed an open letter Monday in support of the FDA’s authority “to approve and regulate safe, effective medicines for every American.”

The letter also advocated a reversal of the mifepristone decision from a judge with “no scientific training,” saying it “set a precedent for diminishing FDA’s authority over drug approvals, and in so doing, creates uncertainty for the entire biopharma industry.”

In a separate statement, the biotech industry group BIO’s interim president and CEO, Rachel King, emphasized the “dangerous precedent” the decision sets.

“The preliminary ruling by a federal judge in Texas is an assault on science and the FDA’s long-standing role as the authority to make decisions on the safety and efficacy of medicines. For a court to invalidate the approval of a drug that was reviewed and approved more than two decades ago is without precedent. As legal scholars have noted, the courts do not have the medical expertise to make these types of scientific determinations,” King said.

The main lobbying group for the pharmaceutical industry, PhRMA, criticized Kacsmaryk’s ruling as undermining the regulatory process.

“PhRMA has serious concerns with any court substituting its opinion for the FDA’s expert approval decision-making,” said James C. Stansel, the association’s executive vice president, general counsel and corporate secretary. Stansel added that such a decision could have a “chilling effect on the research and development ecosystem.”

The pharmacutical sector is a huge part of the American economy. Of the world’s 25 largest phamacutical companies, 10 are based in the US, and most of the others have a large base of operations in the country.

Often, the US market is the first to get access to new drugs, but that could change if lawsuits undermine the regulatory integrity of the FDA process, said Susan Lee, partner in the law firm Goodwin’s Life Sciences group and Life Sciences Regulatory & Compliance practice, who works with companies to get drugs approved by the FDA.

“If there do tend to be more lawsuits like this, I wonder if there might be a little bit of a tendency to not always look at the US as the first market,” Lee said. “Some manufacturers may say ‘we’d rather go to Europe, where we’re not going to be sued on a jurisdiction-by-jurisdiction basis.’ “

Lee also wonders whether manufacturers will abandon efforts to develop drugs that could be considered unappealing to some, such as those that help women’s health or work to prevent HIV.

“I think there are just certain sectors that are already kind of thinking about whether they might also have a target on their back. I’ve definitely heard that discussed,” Lee said.

The groups at the heart of the Texas case have not disclosed any further plans regarding lawsuits over medications, but experts say they are already hearing concern.

“I’ve already been getting questions from lawmakers and other people about ‘could the Covid vaccine be next?’ or other things that may have stigma around it,” said Dr. Kristyn Brandi, an ob/gyn and abortion provider in New Jersey and a spokesperson for the American College of Obstetricians and Gynecologists.

The Covid-19 vaccines have been thoroughly tested and found to be safe and effective, but they’re the subject of conspiracy theories and misunderstanding about how mRNA vaccines were tested. Beliefs that the vaccines were tested on recently harvested aborted fetal cells made some people decidedly anti-vaccine.

Dr. Lynn R. Goldman, professor and dean of the Milken Institute School of Public Health at George Washington University, is also concerned that mRNA vaccines could be targeted soon.

“There might be people who disagree with some of the technologies that are used by vaccine makers, like the mRNA vaccines, but feeling uncomfortable about a technology is not the same thing as identifying that there is risk,” she said in the Protect Our Care conversation.

Members of the LGBTQ+ community may also be vulnerable, experts say, as activists could target puberty blockers or hormones used in gender-affirming therapy.

“I don’t like to do slippery slope, but I’m also very worried about things like gender-affirming care, since there’s already been so many laws about that recently in other states,” Brandi said.

There is political pressure against other vaccines, antidepressants and psychotropic medicines, among others, former FDA Commissioner Margaret Hamburg and former Principal Deputy Commissioner Joshua Sharfstein wrote in an editorial published Thursday in the journal Science.

“If judges begin to dictate the terms of medication access, then others will seek to use ideology and influence to advance their agendas,” they warn.

Goldman said that any legal decision that could undermine the FDA drug approval process would ultimately hurt the doctors who prescribe them and the people who use them.

Doctors don’t have time to vet all the studies used to prove that a drug is safe and effective, so they rely on the FDA for this work, she said. Court interference could confuse this process.

“I think that this is, for doctors, an incredibly serious moment, because up to now, we have been able to trust that an approval by the FDA is a science-based decision and that we can say that if the FDA has approved a drug, that it is safe for us to use,” Goldman said.

A lack of confidence in the drug approval process will ultimately hurt people far beyond the most recent decision, Protect Our Care Chair Leslie Dach says.

“Confidence that the FDA can do its work is essential for clinicians and patients who depend on it in its decision-making for matters of life and death,” Dach said.

A new approach to a Covid-19 nasal vaccine shows early promise | CNN

Scientists in Germany say they’ve been able to make a nasal vaccine that can shut down a Covid-19 infection in the nose and throat, where the virus gets its first foothold in the body.

In experiments in hamsters, two doses of the vaccine – which is made with a live but weakened form of the coronavirus that causes Covid-19 – blocked the virus from copying itself in the animals’ upper airways, achieving “sterilizing immunity” and preventing illness, a long-sought goal of the pandemic.

Although this vaccine has several more hurdles to clear before it gets to a doctor’s office or drug store, other nasal vaccines are in use or are nearing the finish line in clinical trials.

China and India both rolled out vaccines given through the nasal tissues last fall, though it’s not clear how well they may be working. Studies on the effectiveness of these vaccines have yet to be published, leaving much of the world to wonder whether this approach to protection really works in people.

The US has reached something of a stalemate with Covid-19. Even with the darkest days of the pandemic behind us, hundreds of Americans are still dying daily as the infection continues to simmer in the background of our return to normal life.

As long as the virus continues to spread among people and animals, there’s always the potential for it mutate into a more contagious or more damaging version of itself. And while Covid infections have become manageable for most healthy people, they may still pose a danger to vulnerable groups such as the elderly and immunocompromised.

Researchers hope next-generation Covid-19 vaccines, which aim to shut down the virus before it ever gets a chance to make us sick and ultimately prevent the spread of infection, could make our newest resident respiratory infection less of a threat.

One way scientists are trying to do that is by boosting mucosal immunity, beefing up immune defenses in the tissues that line the upper airways, right where the virus would land and begin to infect our cells.

It’s a bit like stationing firefighters underneath the smoke alarm in your house, says study author Emanuel Wyler, a scientist at the Max Delbruck Center for Molecular Medicine in the Helmholtz Association in Berlin.

The immunity that’s created by shots works throughout the body, but it resides primarily in the blood. That means it may take longer to mount a response.

“If they are already on site, they can immediately eliminate the fire, but if they’re like 2 miles away, they first need to drive there, and by that time, one-third of the house is already in full flames,” Wyler said.

Mucosal vaccines are also better at priming a different kind of first responder than injections do. They do a better job of summoning IgA antibodies, which have four arms to grab onto invaders instead of the two arms that the y-shaped IgG antibodies have. Some scientists think IgA antibodies may be less picky about their targets than IgG antibodies, which makes them better equipped to deal with new variants.

The new nasal vaccine takes a new approach to a very old idea: weakening a virus so it’s no longer a threat and then giving it to people so their immune systems can learn to recognize and fight it off. The first vaccines using this approach date to the 1870s, against anthrax and rabies. Back then, scientists weakened the agents they were using with heat and chemicals.

The researchers manipulated the genetic material in the virus to make it harder for cells to translate. This technique, called codon pair deoptimization, hobbles the virus so it can be shown to the immune system without making the body sick.

“You could imagine reading a text … and every letter is a different font, or every letter is a different size, then the text is much harder to read. And this is basically what we do in codon pair deoptimization,” Wyler said.

In the hamster studies, which were published Monday in the journal Nature Microbiology, two doses of the live but weakened nasal vaccine created a much stronger immune response than either two doses of an mRNA-based vaccine or one that uses an adenovirus to ferry the vaccine instructions into cells.

The researchers think the live weakened vaccine probably worked better because it closely mimics the process of a natural infection.

The nasal vaccine also previews the entire coronavirus for the body, not just its spike proteins like current Covid-19 vaccines do, so the hamsters were able to make immune weapons against a wider range of targets.

As promising as all this sounds, vaccine experts say caution is warranted. This vaccine still has to pass more tests before it’s ready for use, but they say the results look encouraging.

“They did a very nice job. This is obviously a competent and thoughtful team that did this work, and impressive in the scope of what they did. Now it just needs to be repeated,” perhaps in primates and certainly in humans before it can be widely used, said Dr. Greg Poland, who designs vaccines at the Mayo Clinic. He was not involved in the new research.

The study began in 2021, before the Omicron variant was around, so the vaccine tested in these experiments was made with the original strain of the coronavirus. In the experiments, when they infected animals with Omicron, the live but weakened nasal vaccine still performed better than the others, but its ability to neutralize the virus was diminished. Researchers think it will need an update.

It also needs to be tested in humans, and Wyler says they’re working on that. The scientists have partnered with a Swiss company called RocketVax to start phase I clinical trials.

Other vaccines are further along, but the progress has been “slow and halting,” Poland said. Groups working on these vaccines are struggling to raise the steep costs of getting a new vaccine to market, and they’re doing it in a setting where people tend to think the vaccine race has been won and done.

In reality, Poland said, we’re far from that. All it would take is another Omicron-level shift in the evolution of the virus, and we could be back at square one, with no effective tools against the coronavirus.

“That’s foolish. We should be developing a pan-coronavirus vaccine that does induce mucosal immunity and that is long-lived,” he said.

At least four nasal vaccines for Covid-19 have reached late-stage testing in people, according to the World Health Organization’s vaccine tracker.

The nasal vaccines in use in China and India rely on harmless adenoviruses to ferry their instructions into cells, although effectiveness data for these has not been published.

Two other nasal vaccines are finishing human studies.

One, a recombinant vaccine that can be produced cheaply in chicken eggs, the same way many flu vaccines are, is being put through its paces by researchers at Mount Sinai in New York City.

Another, like the German vaccine, uses a live but weakened version of the virus. It’s being developed by a company called Codagenix. Results of those studies, which were carried out in South America and Africa, may come later this year.

The German team says it’s eagerly watching for the Codagenix data.

“They will be very important in order to know where whether this kind of attempt is basically promising or not,” Wyler said.

They have reason to worry. Respiratory infections have proved to be tough targets for inhaled vaccines.

FluMist, a live but weakened form of the flu virus, works reasonably well in children but doesn’t help adults as much. The reason is thought to be that adults already have immune memory for the flu, and when the virus is injected into the nose, the vaccine mostly boosts what’s already there.

Still, some of the most potent vaccines such as the vaccine against measles, mumps and rubella use live attenuated viruses, so it’s a promising approach.

Another consideration is that live vaccines can’t be taken by everyone. People with very compromised immunity are often cautioned against using live vaccines because even these very weakened viruses may be risky for them.

“Although it’s strongly attenuated, it’s still a real virus,” Wyler said, so it would have to be used carefully.

As women continue to die due to pregnancy or childbirth each year in the United States, new federal data shows that the nation’s maternal death rate rose significantly yet again in 2021, with the rates among Black women more than twice as high as those of White women.

Experts said the United States’ ongoing maternal mortality crisis was compounded by Covid-19, which led to a “dramatic” increase in deaths.

The number of women who died of maternal causes in the United States rose to 1,205 in 2021, according to a report from the National Center for Health Statistics, released Thursday by the US Centers for Disease Control and Prevention. That’s a sharp increase from years earlier: 658 in 2018, 754 in 2019 and 861 in 2020.

That means the US maternal death rate for 2021 – the year for which the most recent data is available – was 32.9 deaths per 100,000 live births, compared with rates of 20.1 in 2019 and 23.8 in 2020.

The new report also notes significant racial disparities in the nation’s maternal death rate. In 2021, the rate for Black women was 69.9 deaths per 100,000 live births, which is 2.6 times the rate for White women, at 26.6 per 100,000.

The data showed that rates increased with the mother’s age. In 2021, the maternal death rate was 20.4 deaths per 100,000 live births for women under 25 and 31.3 for those 25 to 39, but it was 138.5 for those 40 and older. That means the rate for women 40 and older was 6.8 times higher than the rate for women under age 25, according to the report.

The maternal death rate in the United States has been steadily climbing over the past three decades, and these increases continued through the Covid-19 pandemic.

Questions remain about how the pandemic may have affected maternal mortality in the United States, according to Dr. Elizabeth Cherot, chief medical and health officer for the infant and maternal health nonprofit March of Dimes, who was not involved in the new report.

“What happened in 2020 and 2021 compared with 2019 is Covid,” Cherot said. “This is sort of my reflection on this time period, Covid-19 and pregnancy. Women were at increased risk for morbidity and mortality from Covid. And that actually has been well-proven in some studies, showing increased risks of death, but also being ventilated in the intensive care unit, preeclampsia and blood clots, all of those things increasing a risk of morbidity and mortality.”

The American College of Obstetricians and Gynecologists previously expressed “great concern” that the pandemic would worsen the US maternal mortality crisis, ACOG President Dr. Iffath Abbasi Hoskins said in a statement Thursday.

“Provisional data released in late 2022 in a U.S. Government Accountability Office report indicated that maternal death rates in 2021 had spiked—in large part due to COVID-19. Still, confirmation of a roughly 40% increase in preventable deaths compared to a year prior is stunning new,” Hoskins said.

“The new data from the NCHS also show a nearly 60% percent increase in maternal mortality rates in 2021 from 2019, just before the start of the pandemic. The COVID-19 pandemic had a dramatic and tragic effect on maternal death rates, but we cannot let that fact obscure that there was—and still is—already a maternal mortality crisis to compound.”

Health officials stress that people who are pregnant should get vaccinated against Covid-19 and that doing so offers protection for both the mother and the baby.

During the early days of the pandemic, in 2020, there was limited information about the vaccine’s risks and benefits during pregnancy, prompting some women to hold off on getting vaccinated. But now, there is mounting evidence of the importance of getting vaccinated for protection against serious illness and the risks of Covid-19 during pregnancy.

The Covid-19 pandemic also may have exacerbated existing racial disparities in the maternal death rate among Black women compared with White women, said Dr. Chasity Jennings-Nuñez, a California-based site director with Ob Hospitalist Group and chair of the perinatal/gynecology department at Adventist Health-Glendale, who was not involved in the new report.

“In terms of maternal mortality, it continues to highlight those structural and systemic problems that we saw so clearly during the Covid-19 pandemic,” Jennings-Nuñez said.

“So in terms of issues of racial health inequities, of structural racism and bias, of access to health care, all of those factors that we know have played a role in terms of maternal mortality in the past continue to play a role in maternal mortality,” she said. “Until we begin to address those issues, even without a pandemic, we’re going to continue to see numbers go in the wrong direction.”

Some policies have been introduced to tackle the United States’ maternal health crisis, including the Black Maternal “Momnibus” Act of 2021, a sweeping bipartisan package of bills that aim to provide pre- and post-natal support for Black mothers, including extending eligibility for certain benefits postpartum.

As part of the Momnibus, President Biden signed the bipartisan Protecting Moms Who Served Act in 2021, and other provisions have passed in the House.

In the United States, about 6.9 million women have little or no access to maternal health care, according to March of Dimes, which has been advocating in support of the Momnibus.

The US has the highest maternal death rate of any developed nation, according to the Commonwealth Fund and the latest data from the World Health Organization. While maternal death rates have been either stable or rising across the United States, they are declining in most countries.

“A high rate of cesarean sections, inadequate prenatal care, and elevated rates of chronic illnesses like obesity, diabetes, and heart disease may be factors contributing to the high U.S. maternal mortality rate. Many maternal deaths result from missed or delayed opportunities for treatment,” researchers from the Commonwealth Fund wrote in a report last year.

The ongoing rise in maternal deaths in the United States is “disappointing,” said Dr. Elizabeth Langen, a high-risk maternal-fetal medicine physician at the University of Michigan Health Von Voigtlander Women’s Hospital. She was not involved in the latest report but cares for people who have had serious complications during pregnancy or childbirth.

“Those of us who work in the maternity care space have known that this is a problem in our country for quite a long time. And each time the new statistics come out, we’re hopeful that some of the efforts that have been going on are going to shift the direction of this trend. It’s really disappointing to see that the trend is not going in the right direction but, at some level, is going in the worst direction and at a little bit of a faster rate,” Langen said.

“In the health care system, we need to accept ultimate responsibility for the women who die in our care,” she added. “But as a nation, we also need to accept some responsibility. We need to think about: How do we provide appropriate maternity care for people? How do we let people have time off of work to see their midwife or physician so that they get the care that they need? How do all of us make it possible to live a healthy life while you’re pregnant so that you have the opportunity to have the best possible outcome?”
