C.D.C. Study Finds Silent Bird Flu Infections in Dairy Veterinarians
Three dairy veterinarians, including one who worked only in states with no known bird flu outbreaks in cows, had recent, undetected bird flu infections, according to a new study from the Centers for Disease Control and Prevention. The results are based on antibody testing of 150 veterinarians working in 46 U.S. states.
The findings were not entirely surprising, experts said, but did suggest that the virus, known as H5N1, could be infecting cows and people in more states than have been officially reported.
“We do not know the extent of this outbreak in the U.S.,” said Seema Lakdawala, a virologist at Emory University. “There are clearly infections happening that we’re missing.”
Since the bird flu outbreak in dairy cows was first reported last March, the virus has been confirmed in more than 950 herds in 16 states. It has also been detected in 68 people, 41 of whom had contact with sick cows. Most people have had mild symptoms.
The new study, which was published in the C.D.C.’s flagship Morbidity and Mortality Weekly Report, was initially slated for publication several weeks ago but was delayed by the Trump administration’s pause on public communications from health and science agencies.
“It’s important for public health preparedness that we have this data,” said Dr. Nahid Bhadelia, the director of the Boston University Center on Emerging Infectious Diseases.
The study was conducted at a veterinary conference last September; participating vets practiced in 46 different states, as well as in Canada. Of the 150 veterinarians enrolled in the study, 25 of them reported having worked with cows who were either known to have or suspected of having bird flu.
Three of the vets tested positive for antibodies to the virus. None of those three vets had reported working with cows believed to have bird flu. (One had worked with infected poultry.) None recalled any flulike symptoms.
One of the vets worked with cows only in Georgia and South Carolina, states that had not reported any affected herds.
“I think we’ve all suspected that there are many more states, potentially, where the virus is that are not being detected,” Dr. Bhadelia said.
Dr. Lakdawala said that she was surprised that none of the 25 veterinarians who knew that they had worked with infected cows had tested positive for antibodies. But it’s possible that those who knew they were working with infected animals “were taking more precautions,” she said.
None of the three vets who tested positive for antibodies reported wearing masks or goggles. Such precautions are not recommended when working with healthy animals in unaffected regions, the study notes.
Precisely how veterinarians are being infected remains unclear, and vets may have less contact with virus-laden milk than the farm workers who spend their days in milking parlors, Dr. Lakdawala said.
“The vets that we’ve talked to on these farms are involved in all aspects of care for these animals,” she said. “They’re all over these cows, looking at everything.”
The findings highlighted the need for far more testing, experts said, including testing of asymptomatic dairy workers and bovine vets, as well as expanded testing of the nation’s milk supply.
The U.S. Department of Agriculture announced a national program to test bulk samples of milk in December. As of Feb. 7, 40 states were enrolled and actively conducting testing. In Nevada, the bulk testing of milk recently revealed that dairy herds had been infected with a new version of the virus, distinct from the one that had been spreading in dairy cows over the past year.
“The states that haven’t onboarded bulk milk testing should do that, just not assume that because they haven’t had infected herds reported that they have a little bit of leeway,” Dr. Bhadelia said.
When the study was conducted last fall, the virus had been detected in dairy herds in 14 states, as well as in 14 people, four of whom had contact with dairy cows.

Greater weight loss promised by higher-dose Wegovy shot, now approved by FDA
Novo Nordisk to slash Wegovy, Ozempic list prices
Board certified rheumatologist Dr. Mahsa Tehrani discusses Novo Nordisk’s decision to dramatically cut the U.S. list prices for its popular diabetes and weight-loss drugs Ozempic and Wegovy on ‘America Reports.’
NEWYou can now listen to Fox News articles!
The U.S. Food and Drug Administration announced on Thursday its approval of a new, higher-dose Wegovy (semaglutide) injection.
The 7.2 mg dosage, called Wegovy HD, is intended for weight loss and long-term weight loss maintenance for adult patients. It is triple the previous maximum dose of 2.4 mg.
This marks the fourth approval in the FDA’s National Priority Voucher pilot program, which “seeks to expedite approval of applications that address critical national health priorities,” according to FDA Commissioner Dr. Martin Makary.
NEW WEGOVY PILL OFFERS NEEDLE-FREE WEIGHT LOSS – BUT MAY NOT WORK FOR EVERYONE
“The new FDA is moving with unprecedented efficiency on products that advance national priorities,” he said in a press release. “Today’s approval is another demonstration of what the FDA can accomplish when we try bold new things.”

The higher-dose GLP-1 is indicated to “reduce excess body weight and maintain weight reduction long-term in adults with obesity, or overweight with at least one weight-related condition,” per the FDA’s statement.

“The approval of a new higher dose will provide adult patients with an additional therapeutic option, offering the potential for greater weight loss,” the agency stated.
The FDA’s approval, granted to drugmaker Novo Nordisk, was supported by clinical data that found higher doses resulted in additional average weight reduction compared to previous dosing.

Higher-dose patients with both obesity and type 2 diabetes saw similar lowering of blood sugar compared to the lower dose, the agency noted.
The safety profile is consistent with the known side effects of semaglutide, which commonly include gastrointestinal reactions like nausea, vomiting, diarrhea, constipation and abdominal pain.

Skin sensitivity, pain or burning occurred more frequently with higher doses of Wegovy, but generally resolved on their own or with dose reduction, the FDA reported. The agency is investigating these adverse effects.
The FDA warned that Wegovy should not be used by patients with a personal or family history of medullary thyroid carcinoma (a type of thyroid cancer) or who have multiple endocrine neoplasia syndrome type 2 (a rare inherited genetic disorder that causes tumors to develop in certain hormone-producing glands). All patients should see a doctor for guidance on proper use.

Jamey Millar, executive vice president of U.S. operations for Novo Nordisk, commented on this approval in a press release.
“We are excited to bring Wegovy HD injection to adults with obesity who are looking for powerful weight loss, as no other weight-loss medicine has been studied to show superiority to Wegovy HD,” he said.
Millar also noted that Wegovy has been shown to reduce the risk of events such as stroke, heart attack or cardiovascular death in those who also have known heart disease.

Dr. Peter Balazs, a hormone and weight-loss specialist practicing in New York and New Jersey, reflected on results of the STEP UP clinical trial, on which the drug’s approval was based.
Patients taking the higher dose experienced an average weight loss of 20.7% compared to about 16% on the standard dose, the doctor noted. About one-third lost 25% or more of their body weight.

“For patients who start on 2.4 mg and then hit a frustrating plateau, or for those with a very high baseline BMI who may need a stronger metabolic push, this creates a legitimate, evidence-based escalation path rather than forcing an early switch to another drug class,” Balazs, who was not involved in the study, told Fox News Digital.
“That said, I think this is an interesting approval, but I do not expect it to dramatically reshape the GLP-1 landscape,” he went on. “It gives Novo Nordisk an opportunity to remain competitive on efficacy while it continues developing next-generation therapies.”
“This creates a legitimate, evidence-based escalation path.”
“Other drugs have already shown greater efficacy in prior studies, and the broader GLP-1 space is likely to see much more significant change as new molecules enter the market.”
Balazs called the higher dosage a “major jump,” noting that the incidences of stomach- and skin-related side effects at this higher dose are “meaningful.”

“This approval is for obesity management, not diabetes treatment,” the expert emphasized. “For patients with type 2 diabetes, currently approved semaglutide dosing remains lower unless the primary treatment goal is weight loss under the obesity indication.”

March Madness sparks surprising surge in sexual procedure for men
NEWYou can now listen to Fox News articles!
For some men, March Madness isn’t just about brackets — it’s also prime time for a vasectomy.
Previous research has shown that demand for the procedure tends to spike during the NCAA Division I men’s and women’s college basketball tournaments, which are held every spring.
Some surgeons have agreed that this is a real phenomenon, largely because the steady stream of games offers the perfect activity for men recovering on the couch.
MALE FERTILITY RATES CRASH AS DOCTORS REVEAL HEALTH THREATS: ‘SOMETHING VERY WRONG’
A vasectomy is a simple surgical procedure for men that blocks the vas deferens, the tube that transports sperm, serving as a permanent form of contraception.
Recovery typically takes a few days to a week, with doctors recommending rest for 48 hours and light activity soon after.

David Gentile, MD, chief of the department of urology at Highland Hospital, recently spoke to the University of Rochester Medical Center about the uptick in vasectomies during March Madness.
“It’s a great excuse to watch without interruption.”
“We tell patients they should plan on going home and putting their feet up after a vasectomy, so timing the procedure to watch some games while you recover works well,” he said.
“And it’s a great excuse to watch without interruption, as you won’t be able to do physical labor around the house while you’re recovering.”

Jim Dupree, MD, associate professor of urology at Michigan Medicine, has also spoken about the trend.
“Major sporting events are a popular time for men to schedule a vasectomy because we advise them to take it easy for two to three days after the procedure,” he said in a press release for Michigan Medicine.

“For most men, this means sitting on the couch in front of their television, and sporting events offer them something to watch while resting.”

Yet another surgeon, Dr. Ali Dabaja, director of male reproductive and sexual medicine at the Vattikuti Urology Institute at Henry Ford Hospital in Detroit, Michigan, weighed in on the topic in 2024.

“After a vasectomy, we ask men to rest, not to lift anything heavy, and to go back to light duties during that week. So, timing the procedure for watching some games while you recover works well, and it’s a great excuse to watch March Madness without interruption,” he told the Urology Care Foundation.
“Historically, we have usually seen a rise in vasectomy consultations and vasectomies during March Madness,” he went on. “Other urology offices have reported a rise in vasectomies between 20% to 40%.”

A 2018 study published in the journal Urology found that March was one of the higher-volume months for vasectomy procedures, but the highest peaks were actually later in the year, particularly November and December.

There were some limitations to that study, primarily that the monthly variation was observational, and the data lacked context of patients’ behaviors and scheduling.
