UK on alert after H5N1 bird flu spills over to sheep in world-first

In the UK, officials said further testing of the rest of the sheep’s flock has found no other infections. The one infected ewe has been humanely culled to mitigate further risk and to “enable extensive testing.”

“Strict biosecurity measures have been implemented to prevent the further spread of disease,” UK Chief Veterinary Officer Christine Middlemiss said in a statement. “While the risk to livestock remains low, I urge all animal owners to ensure scrupulous cleanliness is in place and to report any signs of infection to the Animal Plant Health Agency immediately.”

While UK officials believe that the spillover has been contained and there’s no onward transmission among sheep, the latest spillover to a new mammalian species is a reminder of the virus’s looming threat.

“Globally, we continue to see that mammals can be infected with avian influenza A(H5N1),” Meera Chand, Emerging Infection lead at the UK Health Security Agency (UKHSA), said in a statement. In the US, the Department of Agriculture has documented hundreds of infections in wild and captive mammals, from cats and bears to raccoons and harbor seals.

Chand noted that, so far, the spillovers into animals have not easily transmitted to humans. For instance, in the US, despite extensive spread through the dairy industry, no human-to-human transmission has yet been documented. But, experts fear that with more spillovers and exposure to humans, the virus will gain more opportunities to adapt to be more infectious in humans.

Chand says that UKHSA and other agencies are monitoring the situation closely in the event the situation takes a turn. “UKHSA has established preparations in place for detections of human cases of avian flu and will respond rapidly with NHS and other partners if needed.”

measles-arrives-in-kansas,-spreads-quickly-in-undervaccinated-counties

Measles arrives in Kansas, spreads quickly in undervaccinated counties

On Thursday, the county on the northern border of Stevens, Grant County, also reported three confirmed cases, which were also linked to the first case in Stevens. Grant County is in a much better position to handle the outbreak than its neighbors; its one school district, Ulysses, reported 100 percent vaccination coverage for kindergartners in the 2023–2024 school year.

Outbreak risk

So far, details about the fast-rising cases are scant. The Kansas Department of Health and Environment (KDHE) has not published another press release about the cases since March 13. Ars Technica reached out to KDHE for more information but did not hear back before this story’s publication.

The outlet KWCH 12 News out of Wichita published a story Thursday, when there were just six cases reported in just Grant and Stevens Counties, saying that all six were in unvaccinated people and that no one had been hospitalized. On Friday, KWCH updated the story to note that the case count had increased to 10 and that the health department now considers the situation an outbreak.

Measles is an extremely infectious virus that can linger in airspace and on surfaces for up to two hours after an infected person has been in an area. Among unvaccinated people exposed to the virus, 90 percent will become infected.

Vaccination rates have slipped nationwide, creating pockets that have lost herd immunity and are vulnerable to fast-spreading, difficult-to-stop outbreaks. In the past, strong vaccination rates prevented such spread, and in 2000, the virus was declared eliminated, meaning there was no continuous spread of the virus over a 12-month period. Experts now fear that the US will lose its elimination status, meaning measles will once again be considered endemic to the country.

So far this year, the Centers for Disease Control and Prevention has documented 378 measles cases as of Thursday, March 20. That figure is already out of date.

On Friday, the Texas health department reported 309 cases in its ongoing outbreak. Forty people have been hospitalized, and one unvaccinated child with no underlying medical conditions has died. The outbreak has spilled over to New Mexico and Oklahoma. In New Mexico, officials reported Friday that the case count has risen to 42 cases, with two hospitalizations and one death in an unvaccinated adult. In Oklahoma, the case count stands at four.

mom-of-child-dead-from-measles:-“don’t-do-the-shots,”-my-other-4-kids-were-fine

Mom of child dead from measles: “Don’t do the shots,” my other 4 kids were fine

Cod liver oil contains high levels of vitamin A, which is sometimes administered to measles patients under a physician’s supervision. But the supplement is mostly a supportive treatment in children with vitamin deficiencies, and taking too much can cause toxicity. Nevertheless, Kennedy has touted the vitamin and falsely claimed that good nutrition protects against the virus, much to the dismay of pediatricians.

“They had a really good, quick recovery,” the mother said of her other four children, attributing their recovery to the unproven treatments.

Tragic misinformation

Most children do recover from measles, regardless of whether they’re given cod liver oil. The fatality rate of measles is nearly 1 to 3 in 1,000 children, who die with respiratory (e.g., pneumonia) or neurological complications from the virus, according to the Centers for Disease Control and Prevention.

Tommey noted that the sibling who died didn’t get the alternative treatments, leading the audience to believe that this could have contributed to her death. She also questioned what was written on the death certificate, noting that the girl’s pneumonia was from a secondary bacterial infection, not the virus directly, a clear effort to falsely suggest measles was not the cause of death and downplay the dangers of the disease. The parents said they hadn’t received the death certificate yet.

Tommey then turned to the MMR vaccine, asking if the mother still felt that it was a dangerous vaccine after her daughter’s death from the disease, prefacing the question by claiming to have seen a lot of “injury” from the vaccine. “Do you still feel the same way about the MMR vaccine versus measles?” she asked.

“Yes, absolutely; we would absolutely not take the MMR. The measles wasn’t that bad, and they got over it pretty quickly,” the mother replied, speaking again of her four living children.

“So,” Tommey continued, “when you see the fearmongering in the press, which is what we want to stop, that is why we want to get the truth out, what do you say to the parents who are rushing out, panicking, to get the MMR for their 6-month-old baby because they think that that child is going to die of measles because of what happened to your daughter?”

Bird flu continues to spread as Trump’s pandemic experts are MIA

Under the Biden administration, OPPR also worked behind the scenes. At the time, it was directed by Paul Friedrichs, a physician and retired Air Force major-general. Friedrichs told CNN that the OPPR regularly hosted interagency calls between the US Centers for Disease Control and Prevention, the USDA, the Administration for Strategic Preparedness and Response, the US Food and Drug Administration, and the National Institutes of Health. When the H5N1 bird flu outbreak erupted in dairy farms last March, OPPR was hosting daily meetings, which transitioned to weekly meetings toward the end of the administration.

“At the end of the day, bringing everybody together and having those meetings was incredibly important, so that we had a shared set of facts,” Friedrichs said. “When decisions were made, everyone understood why the decision was made, what facts were used to inform the decision.”

Sen. Patty Murray (D-Wash.), who co-wrote the bill that created OPPR with former Sen. Richard Burr (R-N.C.), is concerned by Trump’s sidelining of the office.

“Under the last administration, OPPR served, as intended, as the central hub coordinating a whole-of-government response to pandemic threats,” she said in a written statement to CNN. “While President Trump cannot legally disband OPPR, as he has threatened to do, it is deeply concerning that he has moved the statutorily created OPPR into the NSC.”

“As intended by law, OPPR is a separate, distinct office for a reason, which is especially relevant now as we are seeing outbreaks of measles, bird flu, and other serious and growing threats to public health,” Murray wrote. “This should be alarming to everyone.”

Florida man eats feral pig meat, contracts rare biothreat bacteria

B. suis is an extremely infectious bacteria that’s usually found in pigs. The most common symptom in pigs is reproductive losses, such as stillbirths, though they can also develop other symptoms, such as abscesses and arthritis. In humans, it causes an insidious, hard to detect infection called brucellosis, which is used to describe an infection from any Brucella species: B. suis, B. melitensis, B. abortus, and B. canis.

In the US, there are only about 80 to 140 brucellosis cases reported each year, and they’re mostly caused by B. melitensis and B. abortus. People tend to get infected by eating raw (unpasteurized) milk and cheeses. B. suis, however, is generally linked to hunting and butchering feral pigs and hogs.

Until recently, the Brucella species were designated as select agents by the US government, a classification to flag pathogens and toxins that have the potential to be a severe threat to public health, such as if they’re used in a bioterror attack. The current list includes things like anthrax and Ebola virus. Brucella species were originally listed because they can be easily aerosolized, and only a small number of the bacterial cells are needed to spark an infection. In humans, infections can be both localized and systemic and have a broad range of clinical manifestations. Those include brain infections, neurological conditions, arthritis, anemia, respiratory involvement, pancreatitis, cardiovascular complications, like aneurysms, and inflammation of the spinal cord, among many other things.

In January, federal officials removed Brucella species from the select agents list—a designation that limits the types and amount of research that can be done on a pathogen. According to the US Department of Agriculture, the reason for the removal was to ease those limits, thereby making it easier for researchers to conduct veterinary studies and develop vaccines for animals.

Perilous present

After finding B. suis, the doctors went to gather more information about how the man could have contracted this rare species. The man said he wasn’t a hunter, but recalled receiving a gift of feral swine meat on several occasions in 2017 from a local hunter. Though he couldn’t recall the specific hunter who gave him the biohazardous bounty, he did remember handling the raw meat and blood with his bare hands—a clear transmission risk—before cooking and eating it.

report:-mrna-vaccines-are-in-rfk-jr’s-crosshairs;-funding-in-question

Report: mRNA vaccines are in RFK Jr’s crosshairs; funding in question

Ars Technica has reached out to the NIH and HHS for comment and will update this story with any new information provided. The agencies did not respond to comment requests from KFF.

Kennedy’s misinformation

Before becoming the top health official in America, Kennedy had long railed against vaccines, becoming one of the world’s most prominent anti-vaccine advocates and most prolific spreaders of misinformation and disinformation about vaccines. A 2019 study found Kennedy was the single leading source of anti-vaccine ads on Facebook. Kennedy subsequently faced bans from YouTube, Facebook, and Instagram for spreading misinformation.

Researchers directly blame Kennedy and the Trump administration for the attack on vaccine research.

“Kennedy’s war on vaccines has started,” the mRNA vaccine researcher in Philadelphia told KFF.

“There will not be any research funded by NIH on mRNA vaccines,” the scientist in New York similarly told the outlet. “MAGA people are convinced that these vaccines have killed and maimed tens of thousands of people. It’s not true, but they believe that.”

Kennedy has made various statements against vaccines generally, as well as mRNA vaccines specifically. He falsely claimed the vaccine causes severe harms, including causing neurodegenerative diseases, such as Parkinson’s. In 2021, during the height of the pandemic, Kennedy petitioned the Food and Drug Administration to revoke the authorization of COVID-19 vaccines and refrain from approving any future COVID-19 vaccines. A study in 2022, meanwhile, estimated that the vaccines had saved more than 3 million lives and prevented more than 18 million hospitalizations.

The NIH’s recent moves aren’t the first sign that Kennedy will use his powerful position to attack mRNA vaccines. Late last month, Bloomberg reported that HHS was considering canceling a $590 million grant to vaccine-maker Moderna to develop mRNA vaccines against potential pandemic influenza viruses. That includes the H5N1 virus that is currently devastating US poultry and spreading wildly in dairy cows.

An HHS spokesperson told media at the time that “while it is crucial that the US Department and Health and Human Services support pandemic preparedness, four years of the Biden administration’s failed oversight have made it necessary to review agreements for vaccine production.”

It remains unclear what is happening with that grant review. Moderna declined to comment when Ars reached out for any potential updates Monday.

us-measles-outlook-is-so-bad-health-experts-call-for-updating-vaccine-guidance

US measles outlook is so bad health experts call for updating vaccine guidance

With measles declared eliminated from the US in 2000 and national herd immunity strong, health experts have recommended that American children get two doses of the Measles, Mumps, and Rubella (MMR) vaccine—the first between the ages of 12 and 15 months and the second between the ages of 4 and 6 years, before they start school.

Before 12 months, vulnerable infants in the US have been protected in part by maternal antibodies early in infancy as well as the immunity of the people surrounding them. But if they travel to a place where population immunity is unreliable, experts recommend that infants ages 6 to 11 months get an early dose—then follow it up with the standard two doses at the standard times, bringing the total to three doses.

The reason they would need three—and the reason experts typically recommend waiting until 12 months—is because the maternal antibodies infants carry can interfere with the vaccine response, preventing the immune system from mounting long-lasting protection. Still, the early dose provides boosted protection in that 6-to-11-month interval.

In the past, this early, extra dose was recommended for infants traveling internationally—to countries that hadn’t achieved America’s enviable level of herd immunity and were vulnerable to outbreaks. But now, with US vaccination rates slipping, herd immunity becoming spotty, cases rising by the day, and outbreaks simmering in multiple states, the US is no longer different from far-off places that struggle with the extremely infectious virus.

In an article published today in JAMA, prominent health experts—including former Centers for Disease Control and Prevention Director Rochelle Walensky—call for the US to update its MMR recommendations to include the early, extra dose for infants who are not only traveling abroad, but domestically, to any areas where measles is a concern.

“With some local immunization levels inadequate to avert outbreaks and ongoing disease spread in various regions of the country, a dichotomy between domestic and international travel is not appropriate,” the experts write. “For many travel itineraries, there may even be a higher risk of measles exposure at the US point of departure than at the international destinations.”

Vaccinating at-risk infants early is critical to their own health—as well as the people around them, the experts note. “[I]nfants younger than one year face a heightened risk of severe measles-related complications such as pneumonia, encephalitis, and death. Younger infants are also at increased risk of developing subacute sclerosing panencephalitis (SSPE), a rare measles complication that has a high fatality rate and may surface years after initial infection,” according to the experts.

US measles cases reach 5-year high; 15 states report cases, Texas outbreak grows

The US has now recorded over 300 measles cases just three months into 2025, exceeding the yearly case counts for all years after 2019. The bulk of this year’s cases are from an outbreak that erupted in an undervaccinated county in West Texas in late January, which has since spread to New Mexico and Oklahoma.

As of the afternoon of March 14, Texas reports 259 cases across 11 counties, 34 hospitalizations, and one death, which occurred in an unvaccinated 6-year-old girl. New Mexico reports 35 cases across two counties, two hospitalizations, and one death. That death occurred in an unvaccinated adult who did not seek medical treatment and tested positive for the virus posthumously. The cause of death is still under investigation. Oklahoma reports two probable cases linked to the outbreak.

In addition to Texas, New Mexico, and Oklahoma, 12 other states have reported at least one confirmed measles case since the start of the year: Alaska, California, Florida, Georgia, Kentucky, Maryland, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, and Washington. According to the Centers for Disease Control and Prevention, this year has seen three measles outbreaks, defined as three or more related cases.

As of March 13, the CDC reported 301 confirmed cases, which do not include 36 new cases reported today in Texas and two in New Mexico.

“Measles is back”

Since 2000, when health officials victoriously declared measles eliminated from the US thanks to concerted vaccination campaigns, only three other years have had higher tallies of measles cases. In 2014, the country saw 667 measles cases. In 2018, there were 381 cases. And in 2019—when the country was on the verge of losing its elimination status—there was a startling 1,274 cases, largely driven by massive outbreaks in New York. Measles is considered eliminated if there is no continuous spread in the country over the course of at least 12 months. (This is not to be confused with “eradication,” which is defined as “permanent reduction to zero of the worldwide incidence” of an infectious disease. Smallpox and rinderpest are the only pathogens humans have eradicated.)

UMass disbands its entering biomed graduate class over Trump funding chaos

Many schools are now bracing for steep declines in support. At Duke University, administrators have implemented hiring freezes, scaled back research plans, and will cut the number of admitted biomedical PhD students by 23 percent or more, according to reporting by The Associated Press. The school took in $580 million in grants and contracts from the National Institutes of Health last year.

At Vanderbilt University, faculty were sent an email on February 6 instructing them to reduce graduate admissions by half across the board, according to Stat. The outlet also reported that faculty at the University of Washington’s School of Public Health have reduced admissions.

Faculty at the University of Pennsylvania also reported having to rescind admission offers to applicants and were directed to significantly reduce admission rates, according to The Daily Pennsylvanian. The University of Wisconsin-Madison, too, is shrinking its graduate programs, according to the WKOW.com.

Beth Sullivan, who oversees graduate programs at Duke, told the AP that the shrinking classes mean a shrinking pipeline into America’s medical research community, which dominates the world’s health research fields and is a significant force in the country’s economy. “Our next generation of researchers are now poised on the edge of this cliff, not knowing if there’s going to be a bridge that’s going to get them to the other side, or if this is it,” Sullivan said.

“This is a severe blow to science and the training of the next generation of scientists,” Siyuan Wang, a geneticist and cell biologist at the Yale School of Medicine in New Haven, Connecticut, told Nature. “With fewer scientists, there will be less science and innovation that drive societal progress and the improvement of public health.”

large-study-shows-drinking-alcohol-is-good-for-your-cholesterol-levels

Large study shows drinking alcohol is good for your cholesterol levels

The good and the bad

For reference, the optimal LDL level for adults is less than 100 mg/dL, and optimal HDL is 60 mg/dL or higher. Higher LDL levels can increase the risk of heart disease, stroke, peripheral artery disease, and other health problems, while higher HDL has a protective effect against cardiovascular disease. Though some of the changes reported in the study were small, the researchers note that they could be meaningful in some cases. For instance, an increase of 5 mg/dL in LDL is enough to raise the risk of a cardiovascular event by 2 percent to 3 percent.

The researchers ran three different models to adjust for a variety of factors, including basics like age, sex, body mass index, as well as medical conditions, such as hypertension and diabetes, and lifestyle factors, such as exercise, dietary habits, and smoking. All the models showed the same associations. They also broke out the data by what kinds of alcohol people reported drinking—wine, beer, sake, other liquors and spirits. The results were the same across the categories.

The study isn’t the first to find good news for drinkers’ cholesterol levels, though it’s one of the larger studies with longer follow-up time. And it’s long been found that alcohol drinking seems to have some benefits for cardiovascular health. A recent review and meta-analysis by the National Academies of Sciences, Engineering, and Medicine found that moderate drinkers had lower relative risks of heart attacks and strokes. The analysis also found that drinkers had a lower risk of all-cause mortality (death by any cause). The study did, however, find increased risks of breast cancer. Another recent review found increased risk of colorectal, female breast, liver, oral cavity, pharynx, larynx, and esophagus cancers.

In all, the new cholesterol findings aren’t an invitation for nondrinkers to start drinking or for heavy drinkers to keep hitting the bottle hard, the researchers caution. There are a lot of other risks to consider. For drinkers who aren’t interested in quitting, the researchers recommend taking it easy. And those who do want to quit should keep a careful eye on their cholesterol levels.

In their words: “Public health recommendations should continue to emphasize moderation in alcohol consumption, but cholesterol levels should be carefully monitored after alcohol cessation to mitigate potential [cardiovascular disease] risks,” the researchers conclude.

texas-measles-outbreak-spills-into-third-state-as-cases-reach-258

Texas measles outbreak spills into third state as cases reach 258

Texas and New Mexico

Meanwhile, the Texas health department on Tuesday provided an outbreak update, raising the case count to 223, up 25 from the 198 Texas cases reported Friday. Of the Texas cases, 29 have been hospitalized and one has died—a 6-year-old girl from Gaines County, the outbreak’s epicenter. The girl was unvaccinated and had no known underlying health conditions.

The outbreak continues to be primarily in unvaccinated children. Of the 223 cases, 76 are in ages 0 to 4, and 98 are between ages 5 and 17. Of the cases, 80 are unvaccinated, 138 lack vaccination status, and five are known to have received at least one dose of the Measles, Mumps, and Rubella vaccine.

One dose of MMR is estimated to be 93 percent effective against measles, and two doses offer 98 percent protection. It’s not unexpected to see a small number of breakthrough cases in large, localized outbreaks.

Across the border from Gaines County in Texas sits Lea County, where New Mexico officials have now documented 32 cases, with an additional case reported in neighboring Eddy County, bringing the state’s current total to 33. Of those cases, one person has been hospitalized and one person (not hospitalized) died. The death was an adult who did not seek medical care and tested positive for measles only after death. The cause of their death is under investigation.

Of New Mexico’s 33 cases, 27 were unvaccinated and five did not have a vaccination status, and one had received at least one MMR dose. Eighteen of the 33 cases are in adults, 13 are ages 0 to 17, and two cases have no confirmed age.

On Friday, the Centers for Disease Control and Prevention released a travel alert over the measles outbreak. “With spring and summer travel season approaching in the United States, CDC emphasizes the important role that clinicians and public health officials play in preventing the spread of measles,” the agency said in the alert. It advised clinicians to be vigilant in identifying potential measles cases.

The agency stressed the importance of vaccination, putting in bold: “Measles-mumps-rubella (MMR) vaccination remains the most important tool for preventing measles,” while saying that “all US residents should be up to date on their MMR vaccinations.”

US health secretary and long-time anti-vaccine advocate Robert F. Kennedy Jr, meanwhile, has been emphasizing cod liver oil, which does not prevent measles, and falsely blaming the outbreak on poor nutrition.

NCI employees can’t publish information on these topics without special approval

The list is “an unusual mix of words that are tied to activities that this administration has been at war with—like equity, but also words that they purport to be in favor of doing something about, like ultraprocessed food,” Tracey Woodruff, director of the Program on Reproductive Health and the Environment at the University of California, San Francisco, said in an email.

The guidance states that staffers “do not need to share content describing the routine conduct of science if it will not get major media attention, is not controversial or sensitive, and does not touch on an administration priority.”

A longtime senior employee at the institute said that the directive was circulated by the institute’s communications team, and the content was not discussed at the leadership level. It is not clear in which exact office the directive originated. The NCI, NIH and HHS did not respond to ProPublica’s emailed questions. (The existence of the list was first revealed in social media posts on Friday.)

Health and research experts told ProPublica they feared the chilling effect of the new guidance. Not only might it lead to a lengthier and more complex clearance process, it may also cause researchers to censor their work out of fear or deference to the administration’s priorities.

“This is real interference in the scientific process,” said Linda Birnbaum, a former director of the National Institute of Environmental Health Sciences who served as a federal scientist for four decades. The list, she said, “just seems like Big Brother intimidation.”

During the first two months of Donald Trump’s second presidency, his administration has slashed funding for research institutions and stalled the NIH’s grant application process.

Kennedy has suggested that hundreds of NIH staffers should be fired and said that the institute should deprioritize infectious diseases like COVID-19 and shift its focus to chronic diseases, such as diabetes and obesity.

Obesity is on the NCI’s new list, as are infectious diseases including COVID-19, bird flu and measles.

The “focus on bird flu and covid is concerning,” Woodruff wrote, because “not being transparent with the public about infectious diseases will not stop them or make them go away and could make them worse.”
