San Luis Obispo County reports first measles case of 2026
The county health department confirmed a measles infection and is notifying people who may have been exposed at several local facilities.
San Luis Obispo County health officials confirmed the first measles case of 2026 in the area and have begun contact tracing to alert anyone who may have been exposed. The patient is recovering at home while investigators review potential exposure sites.
Public Health identified two locations where the virus may have been transmitted: Family Industrial Medical Center in San Luis Obispo on Oct. 5 from 8:30 a.m. to 10:30 a.m. and Oct. 6 from 12:30 p.m. to 3 p.m., and the Arroyo Grande Community Hospital emergency room on Oct. 7 from 6:30 a.m. to 1 p.m. Residents who were present at those times are advised to monitor for symptoms for up to 21 days.
"Measles is extremely contagious, but it is also preventable with vaccination," said Interim County Health Officer Dr. Rick Rosen. He urged people to verify their vaccination status and seek medical advice if symptoms appear.
Health officials explained that measles spreads through airborne droplets when an infected person coughs, sneezes or even breathes, and the virus can linger in the air for about an hour after the person leaves. The MMR vaccine, administered in two doses, provides roughly 97% protection against measles. The department will issue further updates if additional exposure sites or cases are identified.
