In a potential outbreak, is bird flu testing available for humans? What to know
Several people have tested positive for bird flu in the U.S., raising questions about the availability of tests in the event of a potential outbreak.
As of July 11, the H5N1 virus has affected more than 99 million poultry (in all 50 states), more than 9,500 wild birds (in 48 states) and more than 145 dairy herds (in 12 states), according to data from the Centers for Disease Control and Prevention (CDC).
Five human cases have been reported since 2022, including a farm worker infected in Colorado and dairy workers ill in Texas and Michigan.

How do people get tested for bird flu?
At this point, only governmental health departments are providing H5N1 avian influenza testing, according to Edward Liu, M.D., chief of infectious diseases at Hackensack Meridian Jersey Shore University Medical Center.
“However, the CDC is taking steps to ramp up the nation’s capacity to test for the flu virus, asking private companies to develop and increase the number and types of tests that can effectively detect H5N1 infections in people,” Liu told Fox News Digital via email.

“A recent announcement from the CDC seemed to indicate that multiple private organizations are working on developing tests.”
Private companies, however, will likely not ramp up production unless there is a clear demand for avian flu tests due to increasing numbers, Liu added.

Neal Barnard, M.D., an adjunct professor of medicine at the George Washington University School of Medicine in Washington, D.C., and president of the Physicians Committee for Responsible Medicine, confirmed there are currently no consumer-level tests for bird flu.
“The home tests for flu (which can be bought on Amazon, for example) are not sensitive to bird flu,” he told Fox News Digital in an email.

“If a person has symptoms and an exposure history suggestive of bird flu, a doctor can send a swab sample to the state health department, which can arrange appropriate testing, but this is rarely done.”
CDC’s warning of limited availability of testing
In a June 10 memo, the CDC issued a public statement warning of a lack of testing availability.
“The World Health Organization (WHO) has identified this virus as a major public health concern, as it has the potential to cause a global pandemic,” the statement read.
“The home tests for flu are not sensitive to bird flu.”
“The current testing capabilities for influenza A(H5) are limited, which could hinder efforts to contain and control the virus in the event of an outbreak.”
Currently, only the CDC and certain jurisdictional public health laboratories are equipped to test for and diagnose bird flu, according to the agency.

“This poses a significant problem, as these laboratories may not have the capacity to handle a large number of cases in the event of an H5 epidemic or pandemic,” the statement said.
“This could result in delays in diagnosing and treating individuals, leading to the further spread of the virus.”
It also noted, “The amount of testing required in the event of an emergency may quickly exceed the capacity to test at public health laboratories, both domestically and internationally.”

To address the situation, the CDC called for private companies to design a lab developed test (LDT) to gain regulatory approval from the U.S. Food and Drug Administration (FDA).
The different types of flu tests
The tests currently available to individuals will alert that a person has the flu — but may not be able to determine if it is avian flu (which is a flu A variant) versus other circulating strains of flu, the expert said.
“However, at the least, that broad detection will give enough information for a clinician to start the patient on antiviral medication, like Tamiflu, which currently will treat avian flu,” Liu noted.
A number of tests are available to detect flu viruses, the doctor said.
The most common are rapid influenza diagnostic tests (RIDTs), which detect parts of the virus that stimulate an immune response.

“These tests can provide results within approximately 10 to 15 minutes, but may not be as accurate as other flu tests,” Liu said.
Other flu tests, called rapid molecular assays, detect the genetic material of the flu virus.

“Rapid molecular assays produce results in 15 to 20 minutes and are more accurate than RIDTs,” Liu said.
The CDC has recommended molecular tests due to their greater sensitivity.

“There are several other, more accurate flu tests available that must be performed in specialized laboratories, such as hospitals and public health laboratories,” Liu said.
These advanced tests — reverse transcription polymerase chain reaction (RT-PCR), viral culture and immunofluorescence assays — will be able to differentiate avian flu from other strains of flu, the doctor said.

“These tests require a health care provider to swipe the inside of the nose or the back of the throat with a swab and then send it for testing,” he said. “Results may take one to several hours.”

One walking habit could signal a healthier brain after 80, scientists say
NEWYou can now listen to Fox News articles!
Older adults identified as “super movers” are about half as likely to develop cognitive impairment than their peers.
That’s according to a recent study led by Stony Brook Medicine in New York, which evaluated the cognitive function of 4,000 adults 80 and over who participated in multiple aging and longevity studies over several years.
Among this group, 6% to 10% were classified as super movers, which means they walk at a much faster pace than others of the same age and gender — at speeds comparable to people three decades younger.
COMMON VITAMIN MAY INFLUENCE BRAIN AGING IN WAYS SCIENTISTS DIDN’T EXPECT
The super movers were found to have about half the risk of cognitive decline compared to seniors with typical gait speed.
The findings were published in the journal Neurology on June 16.

“The study reinforces that mobility and brain health are closely connected,” lead study author Dr. Joe Verghese, MD, neurologist at Stony Brook Medicine, told Fox News Digital. “This suggests that preserving mobility may be an important marker of healthy brain aging and resilience.”
‘LONGEVITY GENE’ MAY PROTECT THE BRAIN FROM ALZHEIMER’S BY BOOSTING DNA REPAIR, STUDY FINDS
The most intriguing finding, according to Verghese, was that super movers maintained cognitive function despite having similar dementia-related brain changes as their peers.
In postmortem brain analysis, there was no difference in dementia-related pathologies between the super movers and the slower walkers, the study stated.

“This suggests they may possess resilience mechanisms that help preserve brain function even in the presence of age-related changes,” he said. “Understanding these resilience factors could lead to new strategies for promoting healthy brain aging.”
As the study was observational, there were some limitations, and it does not prove that walking faster prevents dementia, the researchers noted.

“Other factors, such as cardiovascular health, physical fitness or genetics, may also contribute to both faster walking and better cognitive outcomes,” Verghese said.

This study adds to growing evidence that what’s good for the heart and muscles also benefits the brain, he noted, adding that “staying physically active remains one of the most effective, evidence-based ways to support healthy aging.”
“Walking speed is best viewed as a marker of overall health, not a treatment.”
“The broader message is that physical activity is important at any age,” Verghese said. “Walking is an easy step-up point because you don’t need any special equipment. You can do it inside or outdoors, and you can do it on a regular basis. You can walk with a dog, you can walk with a friend.”
Any activity is beneficial if it’s done regularly and with the right intensity, he added.

Rather than just trying to walk faster, the neurologist recommends that seniors focus on maintaining mobility through regular physical activity, strength training, balance exercises and good cardiovascular health.
“Walking speed is best viewed as a marker of overall health, not a treatment,” Verghese noted.
Major public health guidelines from the CDC and U.S. Physical Activity Guidelines recommend at least 150 minutes of moderate-intensity aerobic activity each week, such as brisk walking.

This can be achieved by walking 30 minutes a day, five days a week, or about 20 to 25 minutes most days. Another option is to engage in shorter sessions that add up over the day.

“You have to do it within your health limitations and medical conditions,” Verghese advised. “So if there are any medical concerns, I would get your physician to clear you before starting exercise.” The good thing about walking, he added, is that you can start at a slow pace and then gradually build up to a brisker pace.
“And then adding on strength and balance training, whatever age you are, I think is also important.”

Dr Oz warns Medicare scammers are stealing billions — and your personal information could be next
NEWYou can now listen to Fox News articles!
Washington, D.C. – Medicare fraud is a multibillion-dollar problem that government officials say threatens both taxpayer dollars and Americans’ personal identities.
In a July 6 interview with Fox News Digital at the Great American State Fair in Washington, D.C., Dr. Mehmet Oz warned that every dollar stolen through Medicare fraud is a dollar taxpayers lose – a problem that has worsened since the COVID pandemic.
“If I had to just pick one thing to focus on to make healthcare more affordable in America, I’d go to health fraud and all the waste and abuse that accompanies it,” said Oz, who is the administrator of the Centers for Medicare & Medicaid Services. “And just to put this in perspective, we think it’s about $100 billion a year.”

Medicare fraud can include billing for services that were never provided, overcharging for medical equipment, using stolen patient or doctor information, or performing unnecessary procedures, according to the U.S. Government Accountability Office.

As the Trump administration ramped up efforts to combat fraud, CMS reported $41.9 billion in Medicare program integrity savings in 2025, up 59% from $26.3 billion in 2024.

Medicare fraud not only harms the federal budget and steals from taxpayers, but exposes seniors to identity theft, unnecessary care, higher premiums and reduced access, Oz cautioned.

Removing corruption from the healthcare system will have the greatest impact among seniors, since “so much of the fraud is perpetrated against them,” the administrator said.
“I’m talking about people tricking seniors to give up their Medicare beneficiary numbers, which is like a credit card basically,” he said. “These scammers can take those numbers and use them for all kinds of illegitimate purposes.”

“People are stealing from you by pretending to send you drugs you don’t want, wheelchairs you don’t need, [and] services you never asked for or don’t benefit from,” Oz added.
To prevent this, he shared his top advice for seniors: Do not give your Medicare beneficiary number to anybody, do not answer questions on a phone call from an unknown person and do not give away personal information.

“These scammers are calling seniors, tricking them, and once they have key information, they can steal it,” he said. “And I won’t know it and you won’t know it.”
“We want to protect people who need these programs the most,” Oz went on. “You do that by making sure scoundrels don’t corrupt the systems and steal money out of the till that is designed to help folks in dire straits when they’re vulnerable and in need of services.”
Seniors should never share their Medicare information with unknown people, the administrator advised. (iStock)
Removing fraud could “double the life expectancy of the trust fund that makes all this possible,” Oz predicted.
“If you’re worried about Medicare being there when you’re ready to retire in a couple decades, depending on how old you are, and you’re concerned that it might not last because of all the fraud that’s hitting it … you’ve got a good [reason to] worry,” he said.
