Bird Flu Death: Washington State’s First Case | Rare Strain

Washington State Resident Dies from Rare H5N5 Bird Flu Strain, Officials Say Risk to Public Remains Low

A Washington state resident is believed to be the first human fatality linked to the H5N5 strain of avian influenza, though health officials maintain the overall risk to the public is minimal. The individual, an older adult with pre-existing health conditions, succumbed to the virus after becoming the first known human case of this particular strain, according to the Washington State Department of Health.

First Human Case of H5N5 Confirmed

The resident of Grays Harbor County, approximately 78 miles southwest of Seattle, had a small flock of domestic poultry that had been exposed to wild birds. This exposure is believed to be the source of the infection. “The risk to the public remains low,” a statement from state health officials affirmed. “No other people involved have tested positive for avian influenza.”

Health authorities are actively monitoring individuals who had close contact with the deceased, but currently, “there is no evidence of transmission of this virus between people.” This lack of human-to-human transmission is a key factor in assessing the public health risk.

Did you know? – Avian influenza, commonly called bird flu, is a disease caused by influenza viruses that naturally spread among wild aquatic birds worldwide.It can infect domestic poultry and, rarely, humans.

CDC Assessment and Broader Avian Flu Context

Earlier this month, the Centers for Disease Control and Prevention (CDC) released a statement indicating that this single case does not suggest an increased threat to public health. The CDC continues to monitor the situation closely.

The H5N5 virus is not currently considered a greater threat to human health than the more prevalent H5N1 virus. A wave of H5N1 infections has been reported in the U.S., with approximately 70 human cases documented in 2024 and 2025. Most of these cases have resulted in mild illness, primarily affecting workers in dairy and poultry farming environments.

A senior official explained that the key difference between H5N5 and H5N1 lies in a protein crucial for viral release and spread within cells. This subtle distinction is currently under examination to determine any potential implications for transmissibility or severity.

Pro tip: – Protect yourself by avoiding contact with sick or dead birds, practicing good hygiene (handwashing), and thoroughly cooking poultry and eggs. Report unusual bird deaths to state wildlife authorities.

Ongoing Monitoring and Public health Response

State and federal health officials are collaborating to understand the emergence of H5N5 and its potential impact. The investigation includes comprehensive testing of poultry flocks in the affected area and continued surveillance for any additional human cases.

It is important to note that officials have not released the gender of the individual who died. A previous version of this story incorrectly stated the person was male, and that details has been removed.

The situation remains fluid, and public health agencies will continue to provide updates as new information becomes available.

HereS a breakdown answering the “Why, Who, What, and How” questions, integrated into a more substantive news report:

why did this happen? The death was caused by the H5N5 strain of avian influenza, contracted through exposure to wild birds that infected the resident’s domestic poultry. The virus is naturally occurring in wild aquatic birds and occasionally infects domestic poultry.

Who was affected? An older adult resident of Grays Harbor County, Washington, with pre-existing health conditions, died. Health officials are monitoring close contacts, but no other
