A Grays Harbor, Washington resident who was hospitalized with influenza symptoms earlier this month has been confirmed to have influenza A H5, a type of avian flu. Additional testing shows the virus to be H5N5, an avian influenza virus that has previously been reported in animals but never before in humans. The Centers for Disease Control and Prevention and the Washington State Department of Health currently considers the risk to the public from avian influenza to be low.
According to a news release, the person is an older adult with underlying health conditions and remains hospitalized. The affected person has a mixed backyard flock of domestic poultry at home that had exposure to wild birds. The domestic poultry or wild birds are the most likely source of virus exposure; however, the public health investigation is ongoing. The Washington State Department of Health is working with the local health department and the Washington State Department of Agriculture to complete exposure and animal health investigations.
Public health disease experts have not identified any increased risk to the public.
