Doctors report upticks in severe brain dysfunction among kids with flu

CDC, encephalitis, encephalopathy, flu, health, kids, MMWR, neurological / /

Doctors around the US have anecdotally reported an uptick of children critically ill with the flu developing severe, life-threatening neurological complications, which can be marked by seizures, delirium, hallucinations, decreased consciousness, lethargy, personality changes, and abnormalities in brain imaging.

It’s long been known that the seasonal flu can cause such devastating complications in some children, many with no underlying medical conditions. But doctors have begun to suspect that this year’s flu season—the most severe in over 15 years—has taken a yet darker turn for children. On February 14, for instance, health officials in Massachusetts released an advisory for clinicians to be on alert for neurological complications in pediatric flu patients after detecting a “possible increase.”

With the anecdata coming in, the Centers for Disease Control and Prevention analyzed all the data it has on neurological complications from flu this year and seasons dating back to 2010. Unfortunately, existing surveillance systems for flu do not capture neurological complications in pediatric cases overall—but they do capture such detailed clinical data when a child dies of flu.

An analysis of that data, published today in the CDC’s Morbidity and Mortality Weekly Report, can’t definitively say that this year is out of the norm. For one thing, the flu season is not yet over. But the data so far does suggest it may be one of the more severe seasons in the last 15 years.

Specifically, the CDC received reports of a severe neurological complication called influenza-associated acute necrotizing encephalopathy (ANE). ANE is a severe form of the more general category of influenza-associated encephalopathy or encephalitis (IAE), meaning brain dysfunction or inflammation from the flu.

When a child dies of the flu, clinicians are required to fill out a standardized case report form from the CDC, which collects a large variety of data, including complications. Encephalopathy or encephalitis are included as a checkbox on the form.

Between 2010 and February 8, 2025, 1,840 children died of the flu. Of those, 166 had IAE checked off as a complication. IAE was most prevalent in children aged 2 to 4 but affected children in all age groups under 18. More than half of the cases (54 percent) had no underlying medical conditions, and most (80 percent) were unvaccinated against the flu.

COVID shots protect kids from long COVID—and don’t cause sudden death

Benefits and a non-existent risk

Using an adjusted odds ratio, the researchers found that vaccination reduced the likelihood of developing long COVID with one or more symptoms by 57 percent, and reduced the likelihood of developing long COVID with two or more symptoms by 73 percent. Vaccination prior to infection was also linked to a 75 percent reduction in risk of developing long COVID that impacted day-to-day functioning. The authors note that the estimates of protection are likely underestimates because the calculations do not account for the fact that vaccination prevented some children from getting infected in the first place.

“Our findings suggest that children should stay up to date with current COVID-19 vaccination recommendations as vaccination not only protects against severe COVID-19 illness but also protects against [long Covid],” the authors conclude.

In a second short report in JAMA Network Open, researchers helped dispel concern that the vaccines could cause sudden cardiac arrest or sudden cardiac death in young athletes. This is an unproven claim that was fueled by anti-vaccine advocates amid the pandemic, including the new US Health Secretary and long-time anti-vaccine advocate Robert F. Kennedy Jr.

While previous analyses have failed to find a link between COVID-19 vaccines and sudden cardiac deaths, the new study took a broader approach. The study, led by researchers at the University of Washington, looked at whether the number of sudden cardiac arrests (SCA) and sudden cardiac deaths (SCD) among young athletes changed at all during the pandemic (2020–2022) compared with prior years (2017–2019). The researchers drew records from the National Center for Catastrophic Sports Injury Research. They also collected medical records and autopsy reports on cases among competitive athletes from the youth, middle school, high school, club, college, or professional levels who experienced sudden cardiac arrest or death at any time.

In all, there were 387 cases, with no statistically significant difference in the number of cases in the years prior to the pandemic (203) compared with those during the pandemic (184).

“This cohort study found no increase in SCA/SCD in young competitive athletes in the US during the COVID-19 pandemic, suggesting that reports asserting otherwise were overestimating the cardiovascular risk of COVID-19 infection, vaccination, and myocarditis,” the authors conclude.

RFK Jr. promptly cancels vaccine advisory meeting, pulls flu shot campaign

Indefinite changes

Stat asked the HHS specifically about the Wild to Mild campaign as well as promotional campaigns for other vaccines, but an HHS spokesperson puzzlingly responded with a statement saying: “No, the CDC was not told to take down the flu vaccination campaign webpage,” which wasn’t what the outlet had asked about.

The statement went on to say: “Unfortunately, officials inside the CDC who are averse to Secretary Kennedy and President Trump’s agenda seem to be intentionally falsifying and misrepresenting guidance they receive.” NPR received the same statement.

Meanwhile on Thursday, The Washington Post reported that the HHS told the CDC to indefinitely postpone a meeting of its vaccine advisory committee (the Advisory Committee on Immunization Practices, or ACIP), which Kennedy has criticized. ACIP, comprised of independent experts, meets regularly to review and discuss vaccine safety and efficacy data and vote on recommendations.

ACIP was previously scheduled to meet February 26 to 28 to discuss a large number of vaccines, including those against meningitis, influenza, RSV, chikungunya, HPV, mpox, pneumococcal infections, Lyme disease, COVID-19, and CMV. An HHS spokesperson told the Post that the meeting was “postponed to accommodate public comment in advance of the meeting,” but there is no rescheduled date.

Leading medical experts and organizations, such as the American Medical Association, quickly sent a joint letter urging Kennedy to preserve the meeting. “Each ACIP meeting holds tremendous weight and relevance,” the letter states. ‘Infectious diseases are constantly evolving opponents; vaccines are among the best tools for constantly adapting and responding to the latest public health threats. … Making America healthy requires healthy discussion and timely, evidence-based decisions. This meeting should be no different.”

But, also on Thursday, Politico reported that Kennedy is preparing to remove ACIP members. And, the AP noted earlier that during a speech to HHS employees on Tuesday, Kennedy vowed to investigate the CDC’s childhood vaccine schedule, despite assuring senators prior to his confirmation that he would not make changes to it.

Texas measles outbreak reaches 90 cases; 9 cases in New Mexico

health, Infectious disease, measles, New Mexico, texas, vaccination, virus / /

Other affected counties in Texas include Dawson (6 cases); Ector (1); Lubbock (1); Lynn (1); Terry (20); and Yoakum (4).

In Texas, the majority of the cases continue to be in children: 26 are in infants and young children ages 0 to 4, and 51 are between ages 5 and 17. All but five cases have been in unvaccinated people. Sixteen people (roughly 18 percent) have been hospitalized.

In New Mexico, there have been no hospitalizations, and five of the nine cases are in adults. The other four cases were between the ages of 5 and 17.

Given low vaccination rate in the area and the contagiousness of measles, health officials expect the outbreak to continue to grow. Measles is one of the most infectious viruses known; 90 percent of people who are unvaccinated and exposed will fall ill. The disease is marked by high fevers and a telltale rash and can cause severe complications in some, including younger children.

In the US, about 20 percent of people with measles are typically hospitalized. Five percent develop pneumonia, and up to 3 in 1,000 die of the infection. In rare cases, measles can cause a fatal disease of the central nervous system later in life called Subacute sclerosing panencephalitis. Measles also wipes out immune responses to other infections (a phenomenon known as immune amnesia), making people vulnerable to various illnesses.

Trump admin. fires USDA staff working on bird flu, immediately backpedals

agriculture, bird flu, dairy, H5N1, health, outbreak, poultry, Science, USDA / /

Over the weekend, the Trump administration fired several frontline responders to the ongoing H5N1 bird flu outbreak—then quickly backpedaled, rescinding those terminations and attempting to reinstate the critical staff.

The termination letters went out to employees at the US Department of Agriculture, one of the agencies leading the federal response to the outbreak that continues to plague US dairy farms and ravage poultry operations, affecting over 160 million birds and sending egg prices soaring. As the virus continues to spread, infectious disease experts fear it could evolve to spread among humans and cause more severe disease. So far, the Centers for Disease Control and Prevention has documented 68 cases in humans, one of which was fatal.

Prior to Trump taking office, health experts had criticized the country’s response to H5N1 for lack of transparency at times, sluggishness, inadequate testing, and its inability to halt transmission among dairy farms, which was once considered containable. To date, 972 herds across 17 states have been infected since last March, including 36 herds in the last 30 days.

In a statement to Ars Technica, a USDA spokesperson said that the agency views the response to the outbreak of H5N1—a highly pathogenic avian influenza (HPAI)—as a priority. As such, the agency had protected some positions from staff cuts by granting exemptions, which went to veterinarians, animal health technicians, and others. But not all were exempted, and some were fired.

“Although several positions supporting HPAI were notified of their terminations over the weekend, we are working to swiftly rectify the situation and rescind those letters,” the spokesperson said.

The USDA did not respond to Ars Technica’s questions regarding how many employees working on the outbreak were fired, how many of those terminations were rescinded, or how many employees have been reinstated since the weekend.

The cuts are part of a larger, brutal effort by the Trump administration to slash federal agencies, and the cuts have imperiled other critical government and public services. In recent days, several agencies, including the National Institutes of Health, the CDC, the National Science Foundation, and the Department of Energy, among others, have been gutted. At CDC, cuts devastated the agency’s premier disease detectives program—the Epidemic Intelligence Service—members of which are critical to responding to outbreaks and other health emergencies.

“The country is less safe”: CDC disease detective program gutted

CDC, EIS, health, outbreaks, public health, Trump / /

The cadre of elite disease detectives at the Centers for Disease Control and Prevention is expected to be left in ruin today as the Trump administration continues to slash the federal workforce.

Many members of the CDC’s Epidemic Intelligence Service, EIS—a globally revered public health training program—were informed earlier Friday that they were about to be fired, according to reporting from Stat News. Multiple sources told CBS News that half of EIS officers are among the ongoing cuts.

The Trump administration is ousting thousands of probationary federal workers in a wide-scale effort to dramatically slim agencies.

The EIS is a two-year program filled with competitively selected, highly educated and trained experts. EIS officers are the ones deployed in critical public health situations, such as deadly outbreaks or bioterror attacks. The program has a long, rich history since its establishment in 1951, which includes contributing to the eradication of smallpox, among other achievements.

The deep cuts to the program have horrified those in the public health sphere.

“The country is less safe,” Dr. Anne Schuchat, a former top-ranking CDC official and alumna of the program, told CBS News. “These are the deployable assets critical for investigating new threats, from anthrax to Zika.”

“It’s almost beyond belief,” former CDC director Bill Foege told Stat. He noted that the EIS trainees were critical to stopping the spread of the disastrous West Africa Ebola outbreak of 2014–2016.

The cuts to EIS are just some of those that CDC is facing. CBS News reports that around 1,270 are being cut from the agency, which is around 10 percent of its staff.

Louisiana officially ends mass vaccinations as RFK Jr. comes to power

“Rather than instructing individuals to receive any and all vaccines, LDH staff should communicate data regarding the reduced risk of disease, hospitalization, and death associated with a vaccine and encourage individuals to discuss considerations for vaccination with their healthcare provider,” he wrote.

“Ripped in half”

Susan Hassig, an infectious disease epidemiologist and professor emerita at Tulane University’s School of Public Health, told the Times-Picayune that this is problematic advice. Many people don’t have primary care providers. “They go to an urgent care or a clinic,” Hassig said. “In Louisiana, they go to the emergency room.”

The memo lands amid widespread fear that Kennedy’s appointment will lead to further erosion of America’s trust in vaccination and its vaccination rates. Already, rates of routine childhood vaccination in kindergartners across the nation have slipped into the range of 92 percent, woefully below the 95 percent threshold to prevent onward disease spread. Exemptions from school vaccination requirements are at an all-time high.

Further, the country is also in the midst of the worst flu season in 15 years. The percent of doctor’s visits for influenza-like illnesses (a standard metric for flu season) hit 7.8 percent this week, a high not seen since the 2009–2010 season amid the emergence of the H1N1 swine flu. The Centers for Disease Control and Prevention estimates that there have been at least 29 million illnesses, 370,000 hospitalizations, and 16,000 deaths from flu so far this season. This week, 11 children died of flu, bringing the 2024–2025 pediatric death toll to 68.

Among the recent deaths was a healthy 9-year-old girl in North Carolina, who died from flu complications on January 29. “I literally feel like my heart has been ripped in half,” her mother told WRAL News.

Seasonal flu shots significantly reduce the risk of death, particularly in children.

Measles outbreak in undervaccinated Texas area doubles—again

gaines county, health, measles, outbreak, texas, vaccination rate / /

A measles outbreak in an area of Texas with abysmal vaccination rates continues to mushroom, with cases doubling since Tuesday and expanding into additional counties.

A week ago, officials reported nine confirmed cases in Gaines County, at the border of New Mexico, which has one of the lowest vaccination rates among kindergartners in the state at just about 82 percent. On Tuesday, the cases climbed to 24, all in Gaines. In Friday’s update, the state health department reports that the case count has now reached 48 and spread to three nearby counties, which also have vaccination rates below the 95 percent threshold that prevent vaccine-preventable diseases from spreading onward.

Gaines now reports 42 cases. There’s one case reported in Lynn County to the northeast, which has a 91 percent vaccination rate. Terry County, with a vaccination rate of 94 percent, reports three cases, and Yoakum County, with a vaccination rate of 92.5 percent, reports two cases. Terry and Yoakum are both directly north of Gaines.

As before, all cases are in unvaccinated people or people with unknown vaccination status. Of the 48 cases, 42 are in children, including 13 between the ages of 0 and 4. Thirteen people (27 percent) have been hospitalized.

H5N1 testing in cow veterinarians suggests bird flu is spreading silently

bird flu, CDC, health / /

Three veterinarians who work with cows have tested positive for prior infections of H5 bird flu, according to a study released today by the Centers for Disease Control and Prevention.

The finding may not seem surprising, given the sweeping and ongoing outbreak of H5N1 among dairy farms in the US, which has reached 968 herds in 16 states and led to infections in 41 dairy workers. However, it is notable that none of the three veterinarians were aware of being infected, and none of them worked with cows that were known or suspected to be infected with H5N1. In fact, one of them only worked in Georgia and South Carolina, two states where H5N1 infections in dairy cows and humans have never been reported.

The findings suggest that the virus may be moving in animals and people silently, and that our surveillance systems are missing infections—both long-held fears among health experts.

The authors of the study, led by researchers at the CDC, put the takeaway slightly differently, writing: “These findings suggest the possible benefit of systematic surveillance for rapid identification of HPAI A(H5) virus in dairy cattle, milk, and humans who are exposed to cattle to ensure appropriate hazard assessments.”

Burning in woman’s legs turned out to be slug parasites migrating to her brain

It started with a bizarre burning sensation in her feet. Over the next two days, the searing pain crept up her legs. Any light touch made it worse, and over-the-counter pain medicine offered no relief.

On the third day, the 30-year-old, otherwise healthy woman from New England went to an emergency department. Her exam was normal. Her blood tests and kidney function were normal. The only thing that stood out was a high number of eosinophils—white blood cells that become active with certain allergic diseases, parasitic infections, or other medical conditions, such as cancer. The woman was discharged and advised to follow up with her primary care doctor.

Over the next few days, the scorching sensation kept advancing, invading her trunk and arms. She developed a headache that was also unfazed by over-the-counter pain medicine. Seven days into the illness, she went to a second emergency department. There, the findings were much the same: Normal exam, normal blood tests, normal kidney function, and high eosinophil count—this time higher. The reference range for this count was 0 to 400; her count was 1,050. She was given intravenous medicine to treat her severe headache, then once again discharged with a plan to see her primary care provider.

At home again, with little relief, a family member gave her a prescription sleep aid to help her get some rest. The next day, she awoke confused, saying she needed to pack for a vacation and couldn’t be reasoned with to return to bed. After hours in this fog, her partner brought her to an emergency department for a third time, this time the one at Massachusetts General Hospital.

Getting warmer

In a case report published in the New England Journal of Medicine, doctors explain how they figured out the source of her fiery symptoms—worms burrowing into her brain. By this point, she was alert but disoriented and restless. She couldn’t answer questions consistently or follow commands.

The doctors at Mass General, including a neurologist specializing in infectious diseases, quickly focused their attention on the fact that the woman had recently traveled. Just four days before her feet began burning, she had returned from a three-week trip that included stops in Bangkok, Thailand; Tokyo, Japan; and Hawaii. They asked what she ate. In Thailand, she ate street foods but nothing raw. In Japan, she ate sushi several times and spent most of her time in a hotel. In Hawaii, she again ate sushi as well as salads.

“A sicker America”: Senate confirms Robert F. Kennedy Jr. as health secretary

The US Senate on Thursday confirmed the long-time anti-vaccine advocate Robert F. Kennedy Jr. as Secretary of Health and Human Services.

The vote was largely along party lines, with a tally of 52 to 48. Sen. Mitch McConnell (R–Ky.), a polio survivor and steadfast supporter of vaccines, voted against the confirmation, the only Republican to do so.

Before the vote, Minority Leader Charles Schumer (D–N.Y.) claimed that if there had been a secret ballot today, most Republicans would have voted against Kennedy. “But sadly, and unfortunately for America, Republicans are being strong-armed by Donald Trump and will end up holding their nose and voting to confirm Mr. Kennedy… What a travesty,” Schumer said.

Senator Mike Crapo (R–Idaho) shot back, supporting Kennedy’s nomination and chastising his colleagues for their continued “attacks” on Kennedy. “He has made it very clear that he will support safe vaccinations and just wants to see that the research on them is done and done well,” Crapo said, seemingly not acknowledging the vast wealth of high-quality research that has already been done on vaccine safety and efficacy.

As the top health official for the Trump administration, Kennedy says he will focus on improving nutrition and reducing chronic diseases, in part by cracking down on food additives, processed foods, and the influence of food and drug makers on federal agencies. Prior to his confirmation, he campaigned on the slogan “Make America Healthy Again,” aka MAHA, which he has moved to trademark.

Anti-vaccine advocacy

While his stated goals have drawn support and praise from some lawmakers and health advocates, his confirmation has been highly controversial because he is one of the most prominent and influential anti-vaccine advocates in the country. He has worked for decades to erode trust in safe, life-saving vaccinations as the head of the anti-vaccine organization he founded, Children’s Health Defense, and spread misinformation and conspiracy theories. Upon seeking the confirmation, he transferred his trademark application to an LLC managed by Del Bigtree, another prominent anti-vaccine advocate who has spread conspiracy theories.

Nine unvaccinated people hospitalized as Texas measles outbreak doubles

In an interview with Ars Technica last week, Zach Holbrooks, the executive director of the South Plains Public Health District (SPPHD), which includes Gaines, said that the area has a large religious community that has expressed vaccine hesitancy.

Additional cases likely

Pockets of the county have yet lower vaccination rates than the county-wide averages suggest. For instance, one independent public school district in Loop, in the northeast corner of Gaines, had a vaccination rate of 46 percent in the 2023–2024 school year.

Measles is one of the most infectious diseases known. The measles virus spreads through the air and can linger in the airspace of a room for up to two hours after an infected person has left. Ninety percent of unvaccinated people who are exposed will fall ill with the disease, which is marked by a very high fever and a telltale rash. Typically, 1 in 5 unvaccinated people with measles in the US end up hospitalized, and 1 in 20 develop pneumonia. Between 1 to 3 in 1,000 die of the infection. In rare cases, it can cause a fatal disease of the central nervous system called Subacute sclerosing panencephalitis later in life. Measles can also wipe out immune responses to other infections (a phenomenon known as immune amnesia), making people vulnerable to other infectious diseases.

“Due to the highly contagious nature of this disease, additional cases are likely to occur in Gaines County and the surrounding communities,” the state health department said.

While Gaines is remarkable for its low vaccination rate, vaccination coverage nationwide has slipped in recent years as vaccine misinformation and hesitancy have taken root. Overall, vaccination rates among US kindergartners have fallen from 95 percent in the 2019–2020 school year into the 92 percent range in the 2023–2024 school year. Vaccine exemptions, meanwhile, have hit an all-time high. Health experts expect to see more vaccine-preventable outbreaks, like the one in Gaines, as the trend continues.
