Bird flu death in Washington resident connected to infected dairy cattle

Bird flu death in Washington resident connected to infected dairy cattle

A Yakima County patient with underlying health conditions is the first person in the US to die of avian influenza this year. Health officials are monitoring contacts and say the risk to the public remains low.

A Yakima County resident who contracted avian influenza from infected dairy cattle has passed away, the Yakima Health District announced on Sunday, November 1. This fatality marks the first US death linked to bird flu this year and the third since human cases associated with the ongoing animal outbreaks started in 2024, according to CNN.

The district did not release the person’s name, age or gender, citing the family’s privacy. In its November 1 statement, it said the patient had underlying health conditions, had been exposed to infected cattle at a Yakima County dairy and had been hospitalized with severe illness. The county had announced that hospitalization a day earlier, when it confirmed its second human case.

The same statement disclosed a third confirmed case in a county resident. That person has not been severely ill and has not been hospitalized.

Three cases tied to infected dairy herds

All three Yakima County cases were identified within roughly two and a half weeks, and each followed exposure to infected cows.

Announced Exposure Illness reported by officials Status
Oct. 15 Infected cattle at a county dairy Mild symptoms; no hospitalization required Recovering in home isolation
Oct. 31 Infected cattle at a county dairy Severe manifestation; hospital admission; pre-existing health issues Deceased (reported Nov. 1)
Nov. 1 Infected cattle Mild symptoms; no hospitalization required Outpatient care

The county’s releases do not state the subtype of the virus that infected the three people. The herds themselves carry highly pathogenic H5N1. Federal and state laboratories first confirmed the virus on two Yakima County dairies on October 8, the first known detection in cattle anywhere in Washington. By October 29, 33 dairy herds in the county had tested positive, the health district said.

Washington’s cattle cases arrived more than two years into a national outbreak. When the first Yakima herds were confirmed, the district noted that dairy cattle in 19 states had been infected since the outbreak began in March 2024.

Contact tracing and what “low risk” means

Public health workers are keeping track of individuals who experienced close contact with the patients to watch for signs of illness, collaborating alongside impacted dairy farms to locate employees potentially exposed to infected livestock. Testing is currently made available for any exposed individual who starts showing symptoms. Furthermore, the district noted that it has partnered with various organizations to supply protective gear to dairy facilities for their staff members.

Officials describe the threat to the general public as minimal. Individuals facing elevated danger, the district notes, comprise dairy employees alongside anyone maintaining prolonged or intimate exposure to sick livestock or tainted surroundings. Person-to-person spread of the virus remains exceedingly uncommon and has never been recorded nationwide within the United States, according to the district.

Dr. Dave Atteberry, the district’s health officer, stated that even though the public danger stays low, “we are taking this situation seriously.”

Nationally, the Centers for Disease Control and Prevention counted 72 human cases reported since February 2024 in its most recent situation summary, updated October 15, and described the current public health risk as low. Most people infected in the US worked on farms with infected cattle or poultry, and most illnesses have been mild, CNN reported.

Earlier US deaths were linked to backyard flocks

The first US death came in January 2025, when Louisiana reported that a patient older than 65 with underlying medical conditions had died after severe H5N1 illness. The CDC said at the time that it had found no person-to-person spread. That patient had been exposed to sick and dead birds in a backyard flock.

The second fatality occurred within Washington as well. During November 2025, an elderly resident suffering from pre-existing health issues, living in Grays Harbor County, passed away following an infection caused by H5N5—a specific strain that had never before been documented in human hosts. The individual maintained a backyard flock of domestic birds that had previously come into contact with wild avian populations.

The Yakima County death differs from both in its source: it followed exposure to dairy cattle rather than birds.

What officials recommend

In its October 31 release on the second case, the health district listed precautions for workers and the public:

  • Dairy employees showing signs of illness following potential contact with cattle ought to reach out to a medical professional or the public health agency. Indicators may involve eye redness or irritation, a fever, coughing, a sore throat, nasal congestion, body aches, headaches, and tiredness.
  • Refrain from handling sick or deceased creatures, animal excrement, and potentially tainted surfaces.
  • Pasteurized milk and dairy items remain completely safe, whereas raw or unpasteurized dairy options should be avoided.
  • Keep pets away from raw milk, unpasteurized dairy items, and uncooked meat, as felines are exceptionally vulnerable to H5N1.
  • Getting a seasonal flu shot is advised for individuals aged 6 months and above. While it does not block avian influenza, it decreases the likelihood of contracting both illnesses simultaneously.
  • Quarantine any livestock showing signs of sickness and immediately notify a veterinarian alongside the Washington State Department of Agriculture.

According to CNN, state authorities are also strongly encouraging dairy employees to utilize personal protective gear and to notify supervisors immediately should they develop any symptoms of illness.

The health district announced that fresh updates will be published on its bird flu page each Monday and Thursday afternoon while the investigation proceeds.
