https://www.kiro7.com/news/local/washington-bird-flu-outbreak-spread-seals-study-finds/EJL72QGHTZCM5GPQ4UMQZWZK6U/For some reason they are putting out old information on infections that occurred before the dairy virus existed. It is likely the H5N1 genotype B3.13 that eventually infected dairy cattle, but the birds and seals were infected in 2023 when the virus was still propagating mostly in wild birds. The virus is not the same one that infected the recent Washington poultry flocks. The poultry flocks were not infected by wild birds, but dairy cattle. Early in the dairy infection in both Texas and Michigan it was determined that the infection was spreading herd to herd and from herd to poultry flocks, and that there was no evidence of a wild bird intermediate. Basically all states that have infected cattle also started getting infected poultry flocks because it was found that some dairy workers also worked on other dairy farms and 7% of them also worked on poultry farms.
Washington should be testing their dairy herds because the dairy virus is spread herd to herd and then infects local poultry flocks. It might be transmitted back to dairy herds from infected poultry workers, but flocks are rapidly depopulated, but herds are allowed to shed the virus and infect the human workers for months.
