The Washington State Department of Health (DOH) has confirmed that a resident of Grays Harbor County is the first person in the U.S. known to be infected with the H5N5 strain of avian influenza.
The case also marks the country’s first human bird flu diagnosis since February.
The patient, described by officials as “an older adult with underlying health conditions,” remains hospitalized after showing influenza-like symptoms in early November.

The DOH stated that the individual “had a mixed backyard flock of domestic poultry at home that had exposure to wild birds.
“Additional testing shows the virus to be H5N5, an avian influenza virus that has previously been reported in animals but never before in humans.”

Domestic poultry and wild birds are considered the most likely sources of the virus exposure, though the health investigation is ongoing.
Public health experts have not found any increased risk to the public to date, according to the press release.

“Transmission of avian influenza between humans is extremely rare and has never been documented in the United States,” the report states.

The DOH urges poultry owners, wildlife handlers and others who have contact with animals to exercise caution.
Measures include avoiding contact with sick or dead birds, using appropriate protective equipment and reporting sick wildlife or domestic animals to the Washington State Department of Agriculture (WSDA).

The release also emphasizes that although the seasonal flu vaccine does not prevent bird flu infections, it is important because “infection with both viruses could result in the emergence of an avian influenza virus that is more easily transmitted from person to person.”

Previously this year, the CDC declared the bird flu emergency officially over.
The agency’s emergency response to H5N1 bird flu, which was activated in 2024, was “deactivated” July 2, the agency told Reuters, citing declining animal infections and an absence of human cases since February.

The H5N5 virus is a close cousin of H5N1. While both viruses come from birds and share part of their genetic code, H5N5 has a different “end piece” of its structure that changes how it behaves, experts say.

While H5N1 has caused human illness — and even deaths — for years, H5N5 has mostly been limited to birds until now, per health officials.

Dementia risk signals could lie in simple blood pressure readings, researchers say
NEWYou can now listen to Fox News articles!
Simple measurements taken during routine blood pressure checks could predict dementia risk years before symptoms appear.
That’s according to new research presented this week at the American College of Cardiology’s Annual Scientific Session in Louisiana.
The findings draw on two studies led by researchers at Georgetown University, which suggest that monitoring how blood vessels age and stiffen over time can provide a window into future cognitive health.
LURKING DEMENTIA RISK EXPOSED BY BREAKTHROUGH TEST 25 YEARS BEFORE SYMPTOMS
Data shows rates of dementia and aging-related cognitive decline are expected to increase as populations age, and half of U.S. adults have high blood pressure (hypertension).
Scientists believe that efforts to better address hypertension, a key contributor to heart disease and a risk factor for dementia, could affect both cardiac and brain health.

“Blood pressure management isn’t just about preventing heart attacks and strokes; it may also be one of the most actionable strategies for preserving cognitive health,” Dr. Newton Nyirenda, the study’s lead author and an epidemiologist at Georgetown University in Washington, said in a press release.
The research focused on two metrics, the pulse pressure-heart rate index and estimated pulse wave velocity. Both were calculated using data collected during standard doctor visits, such as heart rate, age and blood pressure.
“Blood pressure management isn’t just about preventing heart attacks and strokes; it may also be one of the most actionable strategies for preserving cognitive health.”
Researchers examined five years of data patterns for more than 8,500 people in the SPRINT trial, a large study of adults 50 years and older with hypertension. In the follow-up, 323 of the participants developed probable dementia.
HIDDEN BRAIN CONDITION MAY QUADRUPLE DEMENTIA RISK IN OLDER ADULTS, STUDY SUGGESTS
In one study, the team found the pulse pressure-heart rate index was a strong independent predictor of dementia risk in adults over 50. For participants under 65, every one-unit increase was associated with a 76% higher risk of developing dementia.

The second study found that adults with consistently elevated or rapidly increasing pulse wave velocity were more likely to develop dementia than those with stable velocity, even after accounting for factors like smoking, gender and cardiovascular history.

“Our findings suggest that vascular aging patterns may provide meaningful insight into future dementia risk,” said Nyirenda. “This reinforces the idea that managing vascular health earlier in life may influence long-term brain health.”

The team emphasized that clinicians should tailor risk assessments and treatment strategies to the individual.
Further studies are needed to confirm these parameters and determine whether changing vascular aging trajectories reduces dementia risk. (iStock)
“You don’t want to wait until a patient starts manifesting cognitive decline before you act,” said senior study author Sula Mazimba, an associate professor at the University of Virginia.

Researchers noted the study could not establish causation. Other limitations included the fact that participants already had hypertension and elevated cardiovascular risk, meaning the findings may not apply to people without those conditions.

Further studies are needed to confirm these findings and to determine whether improving blood vessel health over time could reduce dementia risk.

‘Gas station heroin’ banned in another state amid nationwide crackdowns
NEWYou can now listen to Fox News articles!
A dangerous substance dubbed “gas station heroin” continues to alarm medical professionals, with more states making moves to restrict or ban tianeptine.
Fourteen states have officially classified the tricyclic antidepressant as a Schedule I controlled substance.
Connecticut is the latest state to crack down, officially banning the sale and use of the substance starting on Wednesday.
HEALTH OFFICIALS WARN OF DANGEROUS SUBSTANCE AVAILABLE IN STORES ACROSS THE NATION
Tianeptine, which can produce euphoria in higher doses, can be more potent than morphine and addictive opioids, according to the U.S. Food and Drug Administration.
Some countries have taken steps to restrict how tianeptine is prescribed or dispensed, and have even revised the labels to warn people of its potential addictive qualities.

Misuse of tianeptine can cause severe adverse health effects, including respiratory depression, severe sedation and death, according to the Drug Enforcement Administration.
Some companies market the drug as an aid for pain, anxiety and depression, or as a means of improving mental alertness in a pill, powder, salt or liquid form.
The products are typically sold at convenience stores, gas stations, vape shops and online retailers, and go by names like Tianaa, ZaZa, Neptune’s Fix, Pegasus and TD Red.

Connecticut Lt. Gov. Susan Bysiewicz said in a press release that the schedule change is a necessary step to combat addiction.
“With false marketing that led consumers to believe these are safe products, and with candy-like flavor options, these substances posed a clear threat to those battling substance-use disorder and our youngest residents,” she added.

The Nutmeg State also added Mitragyna speciosa (kratom), 7-hydroxymitragynine, Bromazolam, Flubromazolam, Nitazenes and Phenibut to the schedule classification.
Earlier this month, FDA Commissioner Martin Makary penned a letter sounding the alarm on what he called a “dangerous and growing health trend.”

“I am very concerned,” Makary wrote. “I want the public to be especially aware of this dangerous product and the serious and continuing risk it poses to America’s youth.”
New York-based Robert Schwaner, M.D., vice chair of system clinical affairs at Stony Brook Emergency Medicine, told Fox News Digital that the FDA has never approved tianeptine as a dietary supplement.
“As with heroin and other opioids, significant mu-opioid receptor stimulation ultimately results in a loss of respiratory drive and subsequent cardiac arrest.” (Dekalb County Sheriff’s Office)
“The euphoria at low doses is primarily due to increased serotonergic activity from its serotonin reuptake effects. With increasing doses, the mu-opioid receptor stimulation may become lethal,” said Schwaner. “As with heroin and other opioids, significant mu-opioid receptor stimulation ultimately results in a loss of respiratory drive and subsequent cardiac arrest.”
Schwaner said he believes the substance requires national regulation due to its addictive qualities.

“Acting at the same receptor as opioids, tianeptine has the potential for an individual to develop tolerance, subsequent dependence and withdrawal from its use,” he cautioned.
