Bird flu surges in several US states with reports of new outbreaks: 'Getting worse'
Avian influenza A (H5N1), commonly known as bird flu, continues to make its way through the U.S., as Hawaii joins the list of affected states.
The Hawaiian Department of Agriculture (HDOA) reported last week that bird flu was confirmed in a backyard flock of various birds in Central Oahu.
At least 10 birds — including ducks, geese and a zebra dove — were reported dead on the property on Nov. 12 and were then sent for confirmatory testing.
BIRD FLU LEAVES TEEN IN CRITICAL CONDITION AFTER COUNTRY’S FIRST REPORTED CASE
The department stated in a press release that highly pathogenic avian influenza (HPAI) causes “severe illness with a high mortality rate among affected birds.”

The presence of bird flu was detected through the National Wastewater Surveillance System, marking the first confirmed detection in Hawaii.
The HDOA has issued a quarantine order for the site of infection, requiring all birds on the property to be “depopulated and the premises cleaned and disinfected.”
FIRST CASE OF HUMAN BIRD FLU DIAGNOSED WITHOUT EXPOSURE TO INFECTED ANIMALS, CDC SAYS
It is confirmed to be the same strain that has infected dairy cows and domestic poultry in U.S. mainland states, including California.
As of Nov. 18, California has confirmed 27 human cases of bird flu, according to the California Department of Public Health (CDPH).
The California Department of Food and Agriculture also confirmed bird flu in 335 dairy farms in Central California as of that same date.
“We can’t afford to give this virus more opportunities to spill over into humans.”
These outbreaks have affected more than one-fourth of California’s farms, per reports, boosting the national total in dairy herds to 549 in 15 states.
The CDPH confirmed on its website that the agency is monitoring bird flu in animals and people working closely with poultry and cows, and has distributed protective gear to these individuals.

Meanwhile, Arizona reported its first bird flu outbreak on Nov. 15 in poultry at a commercial farm in Pinal County.
The farmers spotted signs of illness in their poultry on Nov. 11. Officials confirmed that any eggs produced after the onset of illness have not entered the food supply.
PIG INFECTED WITH BIRD FLU FOR FIRST TIME IN US, HEALTH OFFICIALS CONFIRM
Experts believe the surge stems from the Pacific Flyway, where birds are heading south for winter. The potential of human infection is less of a threat, according to state agencies.
Hawaii’s Department of Agriculture reassured that Hawaiians are “unlikely to get sick” from bird flu at this time, as human illness is “uncommon.” Symptoms among humans infected in the U.S. have been mild, the agency added.
California’s Department of Public Health has warned that while human infections are rare, it can happen if the virus enters a person’s eyes, nose or mouth.

People can also be infected by drinking raw milk; touching raw milk, cow or bird feces and other contaminated surfaces; and handling sick or dead animals carrying the virus.
Symptoms of bird flu in humans can include eye redness or discharge, cough, sore throat, runny or stuffy nose, diarrhea, vomiting, muscle or body aches, headaches, fatigue, trouble breathing, high fever, pneumonia and seizures, according to medical experts.
Expert calls for ‘decisive action’
Sam Scarpino, PhD, director of AI and life sciences at Northeastern University in Boston, said he considers the increased H5N1 influenza cases “quite concerning.”

“From ducks and geese in Hawaii and dairy cows in California to human cases in the U.S. and a severe human infection in Canada, it’s clear that the avian influenza outbreak is getting worse, not better,” he told Fox News Digital.
“We can’t afford to give this virus more opportunities to spill over into humans — and the economic costs on the agricultural side are piling up.”

Scarpino suggested that the federal government must take “decisive action” regarding testing and serosurveillance (estimates of antibody levels) of missed infections and wastewater, as well as vaccinating dairy cows against the virus.
“We also need to ensure that farm workers are protected and should strongly consider offering them access to H5N1 vaccines,” he said.
“It’s clear that the avian influenza outbreak is getting worse, not better.”
The expert added that it will be more difficult to differentiate bird flu cases from non-bird flu cases during the seasonal influenza season.
“We need investment from the federal government to ramp up public health laboratory test capacity and educate physicians and hospitals around the need to test influenza A positive samples for H5N1,” Scarpino said.

Dr. Jacob Glanville, CEO of Centivax, a San Francisco biotechnology company, urged people to “stay away from any dead birds and sick birds, pigs or cows” as a preventive measure, and to keep pets away from wild animals.
“This H5N1 has proven extremely lethal in ferrets and primates, and many of the infected birds have been found dead,” Glanville told Fox News Digital. “Researchers have shown it to be capable of airborne transmission between mammals.”
“Stay away from any dead birds and sick birds, pigs or cows,” an expert cautioned. (iStock)
Among the 52 Americans who have been infected with bird flu, Glanville noted that almost all of them were farm workers who had contact with cows or birds.
“Historically, from 2003 to 2024, 261 H5N1 infections have killed about 50% of the infected, being very lethal but not easily transmissible from human to human,” he said.
“Scientists don’t understand why this current strain is causing only mild infections so far, or how many mutations it would take to make it human-human transmissible and more lethal.”

A distraught mother who thought she was having a heart attack was instead hospitalized with broken heart syndrome — otherwise known as takotsubo syndrome (TTS) — less than a year after her veteran son tragically took his own life.
Dawn Turner, 57, of the U.K., lost her son in August of last year.
Just last month, the mom of three awoke with “unbearable” chest pains, she said — and called an ambulance, worried she was going into cardiac arrest. But when she arrived at the hospital, doctors told her she was suffering from the effects of grief caused by a broken heart, as news agency SWNS reported.
SIMPLE DINNER TABLE HABIT LINKED TO POOR DIET AND HIGHER HEALTH RISKS IN ADULTS OVER 60
TTS is a temporary, reversible heart condition often triggered by extreme emotional or physical stress, such as grief, fear or severe illness, according to experts.
Symptoms usually mimic a heart attack, with sudden and severe chest pain and shortness of breath the most common — and it primarily affects women over the age of 50.

Turner, of Eckington in Worcester, said, “I was [sitting] downstairs earlier that night and thought I had a bit of indigestion. I went to bed and just couldn’t get comfortable — I was breaking out in a sweat and had heart palpitations.
“Then, around midnight, I had pain down my arm and in my jaw. I was still putting it down to indigestion… My partner Paul asked me if I was all right, and I said, ‘I think I’m having a heart attack.’”

She said she couldn’t catch her breath — “and my heart felt as though it was missing a beat and then [started] thudding again. For those moments, I truly believed I was having a heart attack.”
“Your heart is all over the place — there’s an extra beat,” Turner was told.
She said her partner called emergency services, and an ambulance arrived within five minutes.
“They came in and linked me up to an ECG. They said, ‘Your heart is all over the place — there’s an extra beat, and it’s all over the place,’” she said, as SWNS reported.
Turner was rushed to the hospital by ambulance.

In emergency care, Turner was also given blood tests.
She added, “They came back and said I didn’t have the enzymes produced from a heart attack in my blood. But they said there [was] something going on.”
After undergoing more tests and seeing a cardiologist, Turner was told she had takotsubo syndrome.

“I told [the doctor] that my heart feels broken. I told her about [my son] Rob, and she said it’s exactly that. She said it’s a real thing, and that I’d been under so much stress. The body can only take so much, and the grief and the stress can be quite physical.”
Turner’s son committed suicide in August 2025 after struggling to get help with his mental health.
He spent 10 years in the Royal Horse Artillery after joining in 2006, when he worked as an artilleryman.
Turner’s son did two tours of duty in Afghanistan, she said. After he returned to civilian life, he began suffering from a number of health conditions. She’s shown above with a flower-draped memorial to her son. (SWNS)
He did two tours of duty in Afghanistan, she said, and returned to civilian life in 2016 before suffering several worsening health conditions.
Turner, who is also the CEO of a veterans charity called Stepway, “When he left the army, he got married, and they settled down in London. He walked straight into a job as a delivery driver. But then his health took a downward spiral, and he started having digestive troubles.”
YOUR HEART MAY BE OLDER THAN YOU THINK — AND THE NUMBER COULD PREDICT DISEASE RISK
He was eventually told he had PTSD — but those symptoms may be similar to those of mild traumatic brain injury, Turner said.
“He was deaf in one ear from using the guns,” she said. “He realized he was putting so much pressure on his marriage, so he moved back up with me. He started to build himself up — then COVID hit.”

Turner said there were unfortunate delays as her son tried to get access to various services and facilities.
“When people lose loved ones, you’re obviously distraught, but you eventually find closure,” she said, per SWNS. “I found peace when I lost my sister in 2015. But with Rob, I can’t find closure because there’s no justice there.”
“I had never really understood that a person could become so overwhelmed by stress and grief that it physically affects the heart,” said the grieving mom. “Broken heart syndrome can look and feel like a heart attack.” (iStock)
Turner is now on the mend and hopes to be fully recovered in a couple of weeks, SWNS reported.
“Until that moment, I had never really understood that a person could become so overwhelmed by stress and grief that it physically affects the heart,” she shared. “Broken heart syndrome can look and feel like a heart attack. It was a warning sign for me, and for anyone. It can change the shape of one of your heart chambers … it can cause some serious damage.”
She added, “The cardiologist told me that thankfully, my heart itself is healthy and there was no damage, but that it will take around two weeks to a month for my heart to reboot itself.”
“Maybe the extra [heart]beat is for Rob. You are carrying on living for him,” her partner told her.
Turner was told she needed to rest, seek counseling and make lifestyle changes to reduce stress.
“Things have settled down, and I’m taking things easy — I’m pacing myself now, and I feel a lot better. Paul said, ‘Maybe the extra beat is for Rob. You are carrying on living for him.’”

Turner said, “That broke me and healed me a little bit all at once.”
Fox News Digital previously reported that broken heart syndrome, which causes the heart to temporarily weaken, has been linked to the brain’s reaction to stress, as studies have found.

In an article published in the European Heart Journal in March 2019, Swiss researchers said they found that the syndrome is linked to the way the brain communicates with the heart.

Caused by intense emotional events, TTS is a rare, temporary condition that weakens the left ventricle and disrupts its normal pumping function.
The syndrome causes the heart’s main pumping chamber to change shape and get larger. The heart muscle becomes weaker, and its pumping action loses strength.

Eating too much salt has long been linked to high blood pressure, but new research suggests it could trick the immune system into prematurely aging the blood vessels.
A preclinical study recently published in the Journal of the American Heart Association has identified a biological chain reaction that links a salty diet to cardiovascular decay.
Scientists at the University of South Alabama observed that mice on a high-salt diet experienced rapid deterioration in their blood vessel function.
HIGH SALT INTAKE LINKED TO FASTER MEMORY DECLINE IN ONE GROUP, STUDY FINDS
After just four weeks of high sodium intake, the small arteries responsible for regulating blood flow lost their ability to relax, according to a press release.
The team found that the cells lining these vessels had entered a state of cellular senescence, a form of premature cellular aging in which cells stop dividing and release a mix of inflammatory signals that can damage surrounding tissue.

The researchers tried to replicate this damage by exposing blood vessel cells directly to salt in a laboratory dish, but the cells showed no harmful effects.

This suggests that salt isn’t directly causing damage to the vascular lining but that the real culprit may be the body’s own defense mechanism, the researchers noted.
Excess salt may trigger the immune system to release a molecule called interleukin-16 (IL-16), which acts as a messenger that instructs blood vessel cells to grow old before their time, according to the study.

Once these cells age, they fail to produce nitric oxide, the essential gas that tells arteries to dilate and stay flexible.
To test whether this process could be reversed, the team turned to a class of experimental drugs known as senolytics.

Using a cancer medication called navitoclax, which selectively clears out aged and dysfunctional cells, the researchers were able to restore nearly normal blood vessel function in the salt-fed mice, the release stated.

By removing the decaying cells created by the high-salt diet, the drug allowed the remaining healthy tissue to maintain its elasticity and respond correctly to blood flow demands.

The study did have some limitations. The transition from mouse models to human treatment remains a significant hurdle, the team cautioned.

Senolytic drugs like navitoclax are still being studied for safety, and the team emphasized that previous trials have shown mixed results regarding their impact on artery plaque.
Additionally, the researchers have not yet confirmed whether the same IL-16 pathway is the primary driver of vascular aging in humans.
