An avian influenza outbreak first detected at Año Nuevo State Park has spread from birds to other species, including northern elephant seals, and is appearing on nearby Bay Area beaches. Researchers are documenting symptoms in individually flipper‑tagged seals while wildlife and public‑health officials monitor the outbreak's geographic and species expansion for risks to humans and domestic animals. The recent detection of a mutated COVID-19 variant in a San Francisco traveler represents an additional regional infectious threat and may complicate public‑health response and resource allocation.
