Washington state resident believed to be the first to die from a rare
strain of bird flu
[November 22, 2025]
GRAYS HARBOR COUNTY, Wash. (AP) — A Washington state resident is
believed to be the first person to die from a rare strain of bird flu,
but state health officials said Friday the risk to the public is low.
The person, an older adult with underlying health conditions, was being
treated for a bird flu called H5N5 after becoming seemingly the first
known human infected by the strain, according to a statement from the
Washington State Department of Health.
The person from Grays Harbor County, about 78 miles (125 kilometers)
southwest of Seattle, had a backyard flock of domestic poultry that had
been exposed to wild birds, health officials said.
“The risk to the public remains low," the statement from state health
officials said. “No other people involved have tested positive for avian
influenza.”
Health officials said they will monitor anyone who came in close contact
with the person, but “there is no evidence of transmission of this virus
between people."

 Earlier this month, the Centers for
Disease Control and Prevention issued a statement about the
infection that said no information would suggest “the risk to public
health has increased as a result of this case.”
H5N5 is not believed to be a greater threat to
human health than the H5N1 virus behind a wave of 70 reported human
infections in the U.S. in 2024 and 2025. Most of those have been
mild illnesses in workers on dairy and poultry farms.
The distinction between H5N5 and H5N1 lies in a protein involved in
releasing the virus from an infected cell and promoting spread to
surrounding cells.
