2026 California Measles Outbreak: 40 Cases Linked to Homeschool Programs Amid Declining Vaccination Rates
Overview
In early 2026, an unvaccinated toddler from Sacramento contracted measles during travel to South Carolina and introduced the virus to Northern California, sparking an outbreak concentrated in Sacramento and Placer counties. The outbreak mainly affected unvaccinated children connected through homeschool enrichment programs, where low vaccination rates and gaps in tracking created vulnerability. Despite California's overall high vaccination coverage, these pockets allowed the highly contagious virus to spread. Public health officials responded quickly with contact tracing and vaccination campaigns, preventing hospitalizations so far. However, the outbreak reflects a broader national resurgence driven by declining vaccination rates, travel-related introductions, and ongoing policy challenges, threatening the U.S. measles elimination status.
