First fatal bird flu case in WA

What we know:

A Washington resident has died from bird flu after exposure to infected cattle at a dairy farm in Yakima County, marking the first avian influenza fatality in the state this year, according to the Yakima County Health District.

The individual had underlying medical conditions. Health officials stated that two other people contracted bird flu from a dairy farm in Yakima County this year, but neither required hospitalization.

WDFW confirms presence of bird flu in Monroe, WA. Here's what we know

The Washington Department of Fish and Wildlife has confirmed the presence of bird flu in birds at Lake Tye Park in Monroe, the city said on Monday. Here's what we know.

The infection pathway stems from wild bird migration. As wild birds fly over Washington, they can introduce the virus to the local environment. When dairy cows encounter infected wild birds or their contaminated surroundings, the cattle can catch bird flu.

Beyond commercial dairy herds, agricultural officials confirmed a bird flu case at a commercial poultry facility in Pierce County, marking the first commercial poultry detection this year. Several other cases have also emerged in small, backyard bird flocks across Kittitas County.

Despite the spread among livestock and birds, the Centers for Disease Control and Prevention reports that human-to-human transmission is extremely rare, has never been documented in the United States, and the general public faces a low health risk.

What we don't know:

The Yakima County Health District did not disclose the deceased person's name, age, or gender, citing medical privacy considerations.

Farmworker advocates raise undercount concerns

What they're saying:

The United Farm Workers union stated it believes official numbers represent a significant undercount of actual infections among agricultural laborers.

According to the union, "workers report symptoms that range from mild upper respiratory infection with pinkeye to severe flu symptoms with bone pain, severe cough and high fever."

The organization added: "Given the current and ongoing ICE surge in the Yakima Valley, many or most of the workers are understandably reluctant to proactively engage with public agencies. Most workers report being given goggles and PPE, but they need comprehensive training on risk and best practices."

Union representatives also indicated that workers fear employer retaliation if they do not follow work instructions.
