Measles Spreads: Riverside Confirms Case
10 Feb
Summary
- Riverside County confirms its first measles case of 2026.
- The unvaccinated child had no recent travel history.
- Vaccination is crucial to prevent rapid disease spread.

Riverside County has reported its first measles case for 2026, involving an unvaccinated child who is currently recovering at home. This confirmation follows recent measles cases in adjacent Orange, Los Angeles, and San Bernardino counties, indicating a wider outbreak in Southern California.
Health officials emphasize that the risk of measles is no longer remote for the county, particularly as this case involved an individual with no recent travel outside the state or country. The situation underscores the critical need for timely measles, mumps, and rubella (MMR) vaccinations.
Public Health recommends the MMR vaccine for children, with the first dose at 12 months and a second between ages 4 and 6. Infants as young as six months may receive a dose if traveling internationally. Measles symptoms, including fever, cough, red eyes, and a rash, typically appear 7-21 days after exposure and spread through airborne droplets.
Early identification and isolation of sick individuals are vital to protect vulnerable populations such as infants under six months, pregnant women, and those with compromised immune systems. The rapid airborne transmission of measles necessitates prompt public health interventions and widespread vaccination efforts.
