The department said in a news release Saturday that the person with measles is an adult who was exposed during international travel. The department did not say whether the person was vaccinated against the virus. On Monday, June 8, the contagious individual visited San Francisco International Airport’s International Terminal — including passport control, customs and the international baggage claim area — between 8:30 a.m. to 11 a.m., the agency said, and also went to Trader Joe’s on Coleman Avenue and the International Halal Market on E Santa Clara Street between 8 p.m. to 10 p.m. Members of the public who visited the sites at those times on June 8 may be at risk of developing measles seven to 10 days after they were exposed, the department said. Officials also warned that any unvaccinated individual traveling or joining large gatherings should be aware of their increased risk of measles if exposed. The department advised any individual who may have been affected to review their immunization records and call their healthcare provider immediately if they are pregnant, have a weakened immune system or are not immunized. They should monitor symptoms for seven to 21 days after the potential exposure. If symptoms develop, the agency urged anyone who believes they may be infected to call ahead to any medical facility before arriving and tell them about the exposure. The department also urged anyone with measles or at risk of developing measles not to attend large gatherings, as measles “is one of the most infectious diseases in the world and spreads very rapidly.” “Given the number of large international events currently happening throughout the Bay Area, it is especially important that any unvaccinated, exposed individual quarantines to the best of their ability and avoids contact with others if feeling unwell,” the department said. In February, the department warned of the first confirmed measles case since May 2025, [when a Santa Clara County resident with measles visited a Panda Express restaurant in Burlingame](https://www.mercurynews.com/2026/02/27/person-with-measles-dined-twice-at-panda-express-in-burlingame/) while infected. Prior to 2025, the last confirmed case of measles in a Santa Clara County resident was in 2019. Common symptoms of measles include fever, cough, runny nose, red eyes, and a rash, which can appear seven to 21 days after the exposure, the agency said. The two-shot measles, mumps and rubella vaccine series is [97% effective at preventing measles](https://www.mercurynews.com/2026/01/12/california-eluded-major-u-s-measles-outbreaks-in-2025/) if a person is exposed and cases are typically milder in vaccinated people. According to the CDC, the virus may infect a vaccinated person if their immune system didn’t respond correctly to the vaccine, or if they were near someone with the virus for a long time. Disease symptoms are generally milder in vaccinated people and vaccinated individuals are less likely to spread the disease to others, according to the CDC. The Santa Clara County Public Health Department said the Bay Area region benefits from very high rates of vaccination against measles. “Exposures like this one remind us of the importance of vaccination. Fortunately, the Bay Area region has strong community immunity, because of our very high rates of vaccination or from childhood exposure decades ago,” said Dr. Sarah Rudman, Health Officer and Public Health Director for the County of Santa Clara. “Two shots of MMR or MMRV vaccine continue to be the best protection against measles and can stop a measles outbreak in its tracks, which is especially important during times of gathering and travel.”
