The H5 avian influenza has spread to Washington state, with 11 confirmed cases and three suspected cases reported by the Department of Health. The state veterinarian, Amber Itle, from the Washington State Department of Agriculture, warns that bird flu is always circulating but can be more pathogenic this year due to its stability.
Birds carry flu viruses just like humans do, and it changes every year. However, the current strain has been circulating for three years without significant mutations. Waterfowl, such as migrating birds, play a crucial role in spreading the virus, which affects backyard flocks, chickens, emus, and turkeys more severely.
Songbirds, on the other hand, are less susceptible to avian influenza viruses due to their higher metabolic rate. Nevertheless, bird feeders can attract waterfowl, posing a risk to pets, especially cats and dogs that don’t avoid dead birds.
While the risk is currently low for the general public, experts recommend taking precautions. If you have pets or backyard flocks, be more cautious. Avoid contact with dead or sick birds, as fecal bacteria can carry the virus.
