Central California records new HPAI H5N1 case in Morro Bay sea lion
A deadly avian influenza strain (HPAI H5N1) has been found in a dead California sea lion along Morro Strand State Beach in Morro Bay, San Luis Obispo County—the first reported case in this county and the third sea lion overall to contract the virus since the outbreak began. Lab confirmation came March 25 after a March 16 sample; previously detections occurred in San Mateo County and at Point Reyes National Seashore, part of a broader Bay Area seabird mortality event. Officials say human risk remains low and advise against approaching sick wildlife, reporting sightings to NOAA. The outbreak has affected multiple marine mammals and seabirds along California’s coast.
