Washington Resident Dies from Rare Bird Flu Strain, Risk Low

A resident of Grays Harbor County, Washington, is believed to be the first person to die from the rare strain of bird flu known as H5N5. The individual, an older adult with existing health conditions, was undergoing treatment for the infection when it was reported, according to the Washington State Department of Health. Health officials emphasized on Friday that the risk to the general public remains low despite this occurrence.

The individual had a backyard flock of domestic poultry that had been exposed to wild birds, which is likely the source of the infection. The statement from the health department noted, “No other people involved have tested positive for avian influenza.” Officials are monitoring those who had close contact with the deceased, but they affirmed, “There is no evidence of transmission of this virus between people.”

Health Officials Provide Reassurances

Earlier this month, the Centers for Disease Control and Prevention (CDC) released a statement clarifying that there is no evidence suggesting an increased risk to public health as a result of this case. The H5N5 strain is not considered a greater threat to human health than the H5N1 virus, which has led to approximately 70 reported human infections in the United States during 2024 and 2025. Most of these cases involved mild illnesses among workers in dairy and poultry farming.

The critical difference between H5N5 and H5N1 lies in the proteins that facilitate the virus’s release from infected cells and promote its spread to surrounding cells. This distinction is significant for understanding the potential risks associated with these viruses.

Public Health Response and Future Monitoring

Health officials are committed to ongoing surveillance and monitoring as they continue to assess the situation. The Washington State Department of Health reassured the community that they will remain vigilant in tracking any developments related to this case. The public can expect regular updates as new information becomes available.

In the context of avian influenza, the current findings underline the importance of maintaining biosecurity measures for poultry and being alert to any unusual health changes among birds or humans. The health department encourages the public to stay informed and to report any suspected cases of illness linked to poultry.

This case serves as a reminder of the ongoing interactions between human health and animal diseases. While the situation is being closely monitored and remains under control, health officials are dedicated to ensuring that the public is well-informed and prepared.
