Summary
More than 2,700 measles cases have been confirmed in the United States this year, CDC data show, pushing infections to their highest level since 1991 with officials expecting the total to keep rising.
Fresno County, which has no local measles cases so far in 2026, urged residents to check whether vaccinations are current and to watch for symptoms as the national outbreak expands.
Two Fresno County cases were recorded in 2025 after exposure to a traveler who returned sick from abroad; the infected people were unvaccinated or not up to date, county health officials said.
The two-dose MMR vaccine remains the main protection, with county officials saying it is more than 90% effective and available through doctors' offices, public health clinics and California's immunization record system.
