The highly pathogenic H5N1 bird flu virus was detected in swine for the first time in the U.S., raising concerns about cross-species transmission. The virus was found in one out of five pigs on an Oregon farm, which led to the euthanization of the swine for further analysis. The farm is under quarantine, and other animals on the premises are under surveillance. Authorities do not believe the virus poses a significant threat to the public but urge caution. Pig farmers are advised to stay vigilant for potential infections. The virus was also detected in a backyard flock in Oregon, resulting in the euthanization of 70 birds.
