San Mateo County, Calif. - San Mateo County Health is working with Santa Clara County Public Health to notify the public of a confirmed case of measles in the area. The case is an adult who recently returned from international travel. The individual, a Santa Clara County resident, was vaccinated and is now isolating at home.

The individual visited Panda Express at 1453 Burlingame Avenue in Burlingame on February 23 and 24, 2026. People who were at the restaurant between 11:30 a.m. and 1:30 p.m. on those days may be at risk of developing measles, especially if unvaccinated, pregnant or immunocompromised.

If you were at this location during these times and develop symptoms, stay home and call your health care provider immediately before seeking care so they are prepared to take care of you. Symptoms include fever, cough, runny nose, red eyes and a rash that spreads over the body.

Those who have been symptom free for more than 21 days after being exposed are no longer at risk for developing measles.

Although the risk of contracting measles is low for those who are fully vaccinated, members of the public should be aware of the situation and watch for symptoms.

There have been two confirmed cases of measles in San Mateo County in 2026, with one case reported in 2025.

San Mateo and Santa Clara counties continue to follow the existing state vaccination guidelines, and those recommended vaccines continue to be covered by health insurance for almost everyone in California. The measles, mumps and rubella (MMR) vaccine and other recommended vaccines help people live long, healthy lives not impaired or cut short by a preventable disease.
