SF Confirms First Measles Case Since 2019

San Francisco has reported its first measles case since 2019. Health officials confirmed on Monday evening that an unvaccinated infant under 12 months old tested positive for the virus. The child had recently traveled internationally before becoming infectious upon returning to the Bay Area. The infant is currently recovering at home, and their household contacts are vaccinated.

Health authorities are reaching out to close contacts outside the home to assess potential exposure. The risk to the general public is considered low at this time. Measles is a highly contagious airborne disease, with symptoms including fever, cough, and rash. Complications can be severe, especially for children.

Officials strongly urge residents to get the measles, mumps, and rubella (MMR) vaccine, noting its 97% effectiveness after two doses. Infants as young as six months can receive an early dose if traveling internationally. Residents are encouraged to consult their healthcare provider for vaccination information.
