A Washington State resident receiving treatment for H5N5 avian influenza died on Friday, the state’s health department said, in the first confirmed human case of this variant globally.
The deceased, a resident of Grays Harbor County, was an older adult with underlying health conditions, the department said in a statement released late on Friday, adding the person owned a backyard flock of mixed domestic birds.
WHY IT MATTERS: Avian influenza has been devastating to Canadian poultry farmers and has led to human illness and death—though recent human cases have been the H5N1 strain.

Bayer’s proposed Roundup settlement faces first signs of pushback in court
Law firms representing nearly 20,000 people who sued Bayer over alleged injuries from its Roundup weedkiller urged a Missouri judge to delay reviewing the German company’s proposed US$7.25 billion nationwide settlement, arguing that rushing would violate the rights of cancer patients and their families.
The department found the avian flu in the flock’s environment, pointing to domestic poultry or wild birds as the likely source of exposure.
It said that the risk to the general public remains low, and no other individuals involved in the case have tested positive for avian influenza, commonly called bird flu.
“Public health officials will continue to monitor anyone who was in close contact with the patient for symptoms,” the department said, adding: “There is no evidence of transmission of this virus between people.”
Those who had exposure to the backyard flock and its environment were also being monitored for potential symptoms, the department said.
