First U.S. Bird Flu Death of 2026 Confirmed in Washington State

A resident in Yakima County, Washington, died on November 1 after developing a severe illness following exposure to infected dairy cattle, according to the Yakima Health District. The death is the first reported U.S. human fatality from bird flu in 2026. The individual had underlying health conditions and had been hospitalized prior to their death, the Yakima Health District stated. Officials have not released the person's age, gender, or occupation.

Human Infections and Public Health Risk

The Yakima Health District has confirmed three human infections associated with infected dairy cattle in Yakima County this fall. The cases include:

• A mild case in a dairy worker announced on October 15.
• The individual who died on November 1.
• A third confirmed patient, announced November 1, who had not developed severe illness or required hospitalization.

Public health officials continue to emphasize that the risk to the general population remains low. While the death in Washington demonstrates that zoonotic infections can have serious consequences for those exposed to infected animals, the CDC has not announced any change to its low-risk assessment for the general public. Regarding transmission, the Yakima Health District stated that transmission between people is "extremely rare" and "has never been documented in the United States."

Outbreak in Dairy Cattle

The human death occurs as an H5N1 avian influenza outbreak expands among dairy cattle. In Washington, the number of infected herds has grown significantly since the state's first detections in October. According to the Washington State Department of Agriculture, as of October 29, 33 dairy herds in Yakima County and one in Benton County had confirmed H5N1. Washington confirmed its first infected dairy herds on October 8.

On November 2, the U.S. Department of Agriculture announced the first confirmed detection of H5N1 genotype B3.13 in dairy cattle in Indiana. This detection resulted from routine testing through the National Milk Testing Strategy rather than testing associated with cattle movement.

Safety and Occupational Precautions

Federal officials maintain that commercially pasteurized milk is safe for consumption because pasteurization effectively inactivates the virus. Milk from affected animals is excluded from the commercial supply. However, health officials caution against drinking unpasteurized milk or eating raw dairy products, which can carry the virus.

People at greatest risk include dairy workers, milkers, veterinarians, and others with close or prolonged contact with infected cows or contaminated environments. To reduce exposure, officials suggest using eye protection, a well-fitted respirator or mask, gloves, and coveralls. Workers are advised to change clothes and boots before going home and to wash hands before eating.

Symptoms of bird flu can include fever, cough, sore throat, muscle aches, trouble breathing, and red or irritated eyes. The CDC states that antiviral flu medicines work best when started early, ideally within 48 hours of symptoms.
