Bird flu causes deaths of cats and zoo animals as virus spreads in US
Just days after the U.S. Department of Agriculture (USDA) issued a new order that all raw (unpasteurized) milk must be tested for bird flu, reports have emerged of animals dying of the virus.
In Los Angeles County, the public health department is investigating the deaths of two cats that reportedly consumed recalled raw milk.
After drinking the milk, the felines displayed symptoms that included lack of appetite, fever and neurologic issues, according to a press release from the Los Angeles County Department of Public Health.
BIRD FLU SURGES IN SEVERAL US STATES WITH REPORTS OF NEW OUTBREAKS: ‘GETTING WORSE’
“The infected cats died after severe worsening of their illness, and subsequently tested positive for influenza A, a rare result in cats,” the release stated.

Health officials are considering these “suspected H5 bird flu cases” and confirmatory testing is underway.
Cats can contract bird flu by consuming infected birds or other animals or drinking raw milk from infected cows, according to health officials.
Although it is possible for cats to transmit influenza strains to humans, there have been no reports of it happening with the current H5 bird flu outbreak.

“The risk of H5 bird flu remains low in Los Angeles County, but this suspected case of the virus in a pet cat that consumed raw milk is a reminder that consuming raw dairy products can lead to severe illness in cats,” said Dr. Barbara Ferrer, director of the Los Angeles County Department of Public Health, in the release.
“To avoid the spread of disease, including H5 bird flu, we strongly encourage residents and their pets to avoid raw dairy and undercooked meat products, limit contact with sick or dead animals, report sick or dead birds, and keep pets or poultry away from wild animals and birds.”
Fox News Digital reached out to the Los Angeles County Department of Public Health for additional comment.

Meanwhile, at the Wildlife World Zoo in Maricopa County, Arizona, a few resident animals have reportedly died after becoming infected with bird flu.
Local reports stated that a cheetah, a mountain lion, a swamphen, an Indian goose and a kookaburra died as a result of bird flu, according to a zoo official.
A white tiger also was confirmed to be infected but “appeared to be responding to treatment,” per the report.

“Maricopa County Department of Public Health (MCDPH) is working closely with state and federal partners to respond to detection of avian influenza in a small number of animals that are part of a zoo collection in Litchfield Park,” health officials stated in a press release this week.
“Overall risk to the public and zoo visitors remains low.”
A zoo representative provided an update to Fox News Digital on Friday.
“Fortunately, we are nine days out without anymore positive cases,” a zoo representative told Fox News Digital. “We also have not had any positive cases with any of our employees or volunteers as a result of avian influenza.” (iStock)
“Fortunately, we are nine days out without anymore positive cases,” the spokesperson said. “We also have not had any positive cases with any of our employees or volunteers as a result of avian influenza.”
“We are all devastated by the loss of five cherished animals, but with over 6,000 animals, we are grateful that the impact was limited thanks to our swift response and robust protocols.”
“We are all devastated by the loss of five cherished animals.”
Continued outbreaks have also been reported among dairy cattle, poultry, waterfowl and wild birds in multiple U.S. states.
Sam Scarpino, PhD, director of AI and life sciences at Northeastern University in Boston, said the animal deaths are “continued signs” that the situation with H5N1 in the U.S. is “getting worse, not better.”

“The reported infections in humans and now domestic cats due to their consumption of raw milk also highlights how dangerous it is for people to consume raw milk,” he told Fox News Digital.
“It’s important that we take steps to better control the transmission of H5N1 in dairy cows and better understand how it’s spreading between states in the U.S.”
“Studies indicate that even a single mutation could significantly enhance its infectivity in humans.”
Dr. Jacob Glanville, CEO of Centivax, a San Francisco biotechnology company, warned that H5N1 has been found in “relatively high concentrations” in raw milk.
“Without pasteurizing it, the virus remains viable in the milk and could potentially infect someone who drinks it,” he told Fox News Digital.

“It’s not that common of an occurrence, as we’ve not seen a rash of H5N1 infections from raw milk drinkers, but the virus is mutating and is therefore a potential risk.”
Although most cows have only had mild infection, Glanville noted that the strain has been “highly virulent” in birds, ferrets and primates.
“The reported infections in humans and now domestic cats due to their consumption of raw milk also highlights how dangerous it is for people to consume raw milk,” an expert told Fox News Digital. (iStock)
“Studies indicate that even a single mutation could significantly enhance its infectivity in humans,” he said.
“Given the virus’ ability to persist in milk and infect mucosal membranes, along with the potential for a pandemic, avoiding raw milk is strongly recommended,” Glanville added.

Amid warnings of a Legionnaires’ disease outbreak on Manhattan’s Upper East Side, health experts say that early recognition of symptoms can mean the difference between a quick recovery and life-threatening complications, especially for high-risk groups.
New York City health officials are urging anyone who has visited the east side of Central Park or Manhattan’s Upper East Side since late June to watch for symptoms.
As of July 6, the New York City Health Department had confirmed 23 cases and 17 hospitalizations associated with the respiratory infection. No deaths have been reported.
NYC HEALTH OFFICIALS WARN OF LEGIONNAIRES’ DISEASE OUTBREAK IN CENTRAL PARK AREA
Officials are investigating contaminated cooling towers as the likely source. They have emphasized that the illness is not spread person-to-person and is not linked to the city’s drinking water.
Health experts say that early recognition of symptoms can mean the difference between a quick recovery and life-threatening complications, especially for high-risk groups. (iStock)
“Legionnaires’ disease is deadly but can be effectively treated if diagnosed early,” said NYC Health Commissioner Dr. Alister Martin in a press release. “New Yorkers at higher risk, including anyone who is 50 and older, those who smoke or people with chronic lung conditions should be especially mindful of their symptoms and seek care as soon as symptoms begin.”
What is Legionnaires’?
Legionnaires’ disease is a type of pneumonia caused by Legionella bacteria.
The bacteria is usually found in lakes, streams and other freshwater environments, but can grow in any area where water sits for a long time, according to the CDC.
RARE TICK-BORNE VIRUS TURNS DEADLY FAST AS US CASES REACH RECORD HIGH, EXPERTS WARN
That can include shower heads, sink faucets, hot tubs, water features/fountains, plumbing systems and other water systems.
When people swallow or breathe in droplets of water that contain Legionella, they can potentially become ill.
Although human transmission is possible in rare cases, the disease is not typically transmitted among people, per the Centers for Disease Control and Prevention.
Symptoms of infection
Infections can lead to severe pneumonia in older people and those with compromised immune systems, according to Dr. Andrew Handel, a pediatric infectious diseases expert at Stony Brook Children’s Hospital on Long Island, New York.
Symptoms of Legionnaires’ disease usually show up between two and 14 days after exposure.

“Legionella infections cause symptoms that are similar to other forms of pneumonia — fever, coughing, difficulty breathing, shortness of breath and chest pain,” Handel previously told Fox News Digital.
“Legionnaires’ disease is deadly but can be effectively treated if diagnosed early.”
The signs are similar to other types of pneumonia, and include the following:
- Cough
- Fever
- Shortness of breath
- Muscle aches and headaches

Some patients may also experience nausea, diarrhea and confusion, the CDC noted.
Diagnosis, treatment and prevention
A medical professional can diagnose the infection with laboratory tests and chest X-rays.
The condition is typically treated with antibiotics. In cases of severe infection, hospitalization may be required for breathing support and IV hydration.
Around 10% of people who contract Legionnaires’ disease will die from those complications — and the mortality risk rises to 25% for those who get Legionnaires’ while staying in a healthcare facility, according to the CDC.

“Treatment needs to be early and aggressive,” Dr. Nathan Goodyear, an Arizona-based integrative medicine expert, previously told Fox News Digital. “Legionella infection is an intracellular infection that requires antibiotic treatment.”
Antibiotics that are appropriate for Legionella infection include Levofloxacin and Azithromycin.

“Therapy can be prescribed orally in healthy individuals… but intravenous antibiotics often prove to be the initial option for treatment secondary to the pathogenicity of the disease,” Goodyear said.
Currently, there are no vaccines for Legionnaires’ disease.

The best strategy to prevent infection is to reduce the growth and spread of the Legionella bacteria. The CDC recommends that building owners and managers use a water management program to reduce the risk.
“New Yorkers at higher risk, including anyone who is 50 and older, those who smoke or people with chronic lung conditions should be especially mindful of their symptoms and seek care as soon as symptoms begin,” city officials stated. (iStock)
To prevent serious illness from Legionnaires’, Goodyear recommends that all smokers kick the habit, and also emphasizes the need to “aggressively support” chronic pulmonary disease.

“Increasing immune support (vitamin D3, vitamin C, Zinc) is required to counter the immune dysfunction associated with advancing age.”
Obesity is another foundational risk factor for all chronic inflammatory diseases, the doctor added.

Journalist Katie Couric is sharing a scary medical episode that she experienced on June 27.
In a post on Substack titled “The Day I’ll Never Remember,” she detailed a sudden episode that left her unable to recall the current month, year and president.
“I thought it was 2024. And I believed Joe Biden was president,” she wrote.
ONE WALKING HABIT COULD SIGNAL A HEALTHIER BRAIN AFTER 80, SCIENTISTS SAY
The event occurred while Couric was attending the Aspen Ideas Festival in Colorado, during which she participated in two public panels — one on AI and one on journalism — both of which she cannot remember at all.
“I have no idea what we talked about, or of what occurred when the panels ended,” she said.

John Molner — Couric’s husband, who was in attendance at the festival and the two panels — also shared his account.
After the event, someone told Molner that Katie wasn’t feeling well. When he reached her, an EMT and a doctor were tending to her. “I could tell something was off,” he wrote. “It could have been altitude sickness, but Katie was definitely not all there.”
WOMAN WITH ADVANCED ALZHEIMER’S REGAINED SPEECH AND MEMORIES AFTER TAKING MAGIC MUSHROOMS
At the hospital, when Couric struggled to recall the year, the president and her grandchildren’s names, doctors began checking for a stroke.
An MRI revealed no signs of stroke, which was a relief, but “Katie’s ‘fog’ became a lot more apparent,” Molner wrote.

“She repeatedly asked me the same questions: ‘What was I doing before we got to the hospital?’ ‘Why am I at the hospital?’”
Couric was ultimately diagnosed with transient global amnesia, a sudden, temporary episode of memory loss that prevents a person from forming new memories and may also erase some recent memories, according to Mayo Clinic.
“The cause seems to be as mysterious as the brain itself.”
It is not caused by a stroke, seizure or head injury, and it usually resolves completely within 24 hours.
“[It’s] just a very weird neural episode that’s pretty uncommon and, at least in most cases, is a ‘one and done’ experience,” Molner said.

Couric said she finally began feeling “like herself” again around 9 p.m. and went to sleep at 2 a.m.
As TGA leaves a “permanent gap in memory” for the duration of the episode and for hours beforehand, Couric said that from around noon on that day until at least 7 p.m. will remain a “big, black hole.”

Data shows that approximately three to eight people per 100,000 will have an episode of transient global amnesia, with people 50 years of age and older at higher risk.
The specific cause of TGA is not known, but some experts believe it stems from a “temporary dysfunction in the brain’s hippocampus — the area responsible for creating new memories,” Couric shared.

“Doctors believe this is driven by brief interruptions in blood or oxygen flow, or microscopic spasm in the blood vessels.”
Episodes could potentially be triggered by intense physical exertion, emotional distress, extreme temperature changes or migraines, experts say.

Approximately 15% of patients will have a recurrence 10 years later.
“Why did this happen to me? Was the altitude an issue? Was I dehydrated? Tired? Stressed? The literature doesn’t seem to indicate that these are contributing factors, but the cause seems to be as mysterious as the brain itself,” Couric wrote.

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.”
