Latest COVID variant, XEC, has spread to half of US states, reports say
The latest strain of the COVID-19 virus, XEC, is circulating across the country.
The new variant has been reported in at least 25 U.S. states, according to data from the Global Influenza Surveillance and Response System (GISRS), as WebMD reported.
Some of the states with the highest cases — 10 or more each — include California, New Jersey and Virginia, the data showed.

As of Friday, the variant is not yet being tracked by the U.S. Centers for Disease Control and Prevention (CDC) or the World Health Organization (WHO).

KP.3.1.1 is still considered the “predominant variant” of the virus, according to the CDC’s website.
Jake Glanville, PhD, an infectious diseases expert and CEO of Centivax in San Francisco, California, told Fox News Digital that XEC represents a shuffling of two descendants of last year’s JN.1 strain.
“Coronaviruses are mutating continuously, so when new strains become dominant, it tends to be because that strain has an infection or transmission advantage over all the other circulating mutant strains out there,” he told Fox News Digital during an on-camera interview.
XEC is an example of such a new, mutated strain, the doctor confirmed.

“So far, it doesn’t appear to have any distinct symptoms or mode of infection,” Glanville said.
“It might be a little more infectious than some other strains, which is why it’s becoming dominant, but there’s no unique cause for concern for the public.”
The current vaccines are based on the KP.2 strain, which itself is also a descendant of JN.1 and a reasonable match for XEC, Glanville noted.

“As XEC doesn’t appear to have any unusual infection symptoms, and is pretty similar to the vaccine strains chosen by the FDA this year, XEC is not a unique concern at this time,” the expert said.
“It’s something that vaccine developers monitor to try to understand at what point they need to make a new vaccine, because eventually XEC or some other strain will mutate enough to escape the current vaccine designs.”

It’s always possible that a new variant will evolve into mutations that cause new types of symptoms, Glanville said, but noted that isn’t currently happening with XEC.
“This looks like the coronavirus that we’re used to,” the doctor said.

Dr. Marc Siegel, senior medical analyst for Fox News and clinical professor of medicine at NYU Langone Medical Center, agreed that the current 2024-2025 vaccines should cover the emerging XEC subvariant.
“Common symptoms include sore throat, congestion, cough, fatigue, nausea and loss of taste,” he told Fox News Digital.
“Eventually, XEC or some other strain will mutate enough to escape the current vaccine designs.”
Siegel recommends the updated vaccine for the elderly, people who are immunocompromised, those with chronic illness, and young children who did not get previous COVID vaccines.

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.

“If we take the fraud out, we could double the life expectancy, which means you, your kids, your kids’ kids … they could all benefit from this beautiful safety net program.”
