A Washington state resident has been hospitalized after contracting an uncommon strain of bird flu, marking the first known human infection tied specifically to this version of the virus. Health officials say the patient—an older individual with underlying health conditions—remains hospitalized as of the most recent update.
The Washington State Department of Health announced that the patient, who keeps backyard poultry, first sought treatment in early November after developing flu-like symptoms. The birds on the property had been exposed to wild birds, long recognized as carriers of the A(H5) avian influenza strain. The case was identified in Grays County.
The infection comes at a time when bird flu has been spreading across the country, with general outbreaks already affecting more than 1,000 dairy cattle herds in 17 states since March 2024. Although the virus has circulated widely among animals, the U.S. Centers for Disease Control and Prevention continues to maintain that the threat to the broader public remains low.
Health officials report that the United States has recorded 71 human cases of bird flu, with California experiencing the highest number. Symptoms in infected individuals resemble those of seasonal influenza, and officials emphasize that there has been no documented person-to-person transmission.
State and local health departments are working alongside the Washington State Department of Agriculture to trace how the patient became infected. While the virus primarily spreads among wild birds, it can also infect poultry and a range of other mammals, a pattern that has increasingly challenged state and federal health agencies.
The rare human case in Washington has drawn attention to the broader implications of animal-borne infections, particularly as outbreaks continue to strain agricultural operations across multiple states. The spread among cattle herds—now confirmed in 17 states—has forced health authorities to balance public-health messaging with reassurance, reiterating that the overall risk to Americans has not changed.
For Washington state officials, the focus remains on containing the local impact. Backyard poultry, especially when exposed to wild birds, presents a known risk factor, and the state has worked to coordinate surveillance and testing efforts across agencies. The involvement of the Washington State Department of Agriculture underscores the dual public-health and agricultural concerns surrounding avian influenza.
Nationally, the wave of animal infections has prompted closer monitoring but not a shift in federal assessments. The CDC continues to note the absence of human-to-human transmission, a key indicator in determining whether an animal-origin virus poses a wider threat.
Still, the emergence of a rare strain in a human patient adds a new dimension to an already extensive series of outbreaks. While officials stress that the risk to the general population is minimal, the case illustrates the persistent challenges posed by viruses that can move between species, particularly in regions where domestic animals and wildlife interact closely.
As the patient continues to receive treatment, public-health agencies say they will maintain investigations into the source of the infection and monitor for any additional cases, even as they continue to emphasize that current evidence does not point to broader risk.
