Oregon Reports First Human Case of Bird Flu

Health officials in Canada and Oregon have reported separate cases of H5N1 avian influenza in humans. A teenager in British Columbia tested positive for the virus, marking the first presumptive human case of avian flu contracted in Canada, with investigations ongoing to determine the source of exposure. In Oregon, a confirmed case is linked to a poultry outbreak affecting approximately 150,000 birds, with the individual recovering from mild symptoms and receiving antiviral treatment. Both health authorities emphasized that there is no evidence of person-to-person transmission and that the public risk remains low. The CDC noted that 52 people across the U.S. have tested positive for H5N1 this year, primarily among farm workers exposed to infected birds. Meanwhile, the H5N1 virus has significantly impacted poultry populations, leading to the deaths of over 100 million birds since 2022.
