California's First Measles Surge Since 2020 Hits Shasta County
California faces its first measles outbreak in six years, driven by a cluster of eight cases in Shasta County, part of 17 confirmed statewide this year. The California Department of Public Health issued an urgent warning on Monday, highlighting the highly contagious virus's return after a lull since 2020. All Shasta patients were unvaccinated or had unknown status, fueling the spread among close contacts like family and neighbors.[1][2]
Outbreak Details and Containment Efforts
Shasta leads with the largest cluster, outpacing cases in Los Angeles, Orange, San Bernardino, and Riverside counties. Health officials note no public threat yet, as infected individuals isolated promptly, preventing new exposure sites. Early detection and contact tracing have been key, with exposure linked to spots like parks and clinics in late January. Nationwide, 2025 saw over 2,200 cases, mostly among the unvaccinated.[3][5]
Protection and Prevention Steps
Two MMR vaccine doses offer 97% protection; check records or get a blood test for immunity. Symptoms include fever, rash, cough, and red eyes—call providers if exposed. With kindergarten vaccination rates above 95%, officials urge boosters for peace of mind amid this surge.[4][1]
