SANTA CLARA (CBS SF) — Health officials issued a warning Tuesday after they say an international traveler to the Silicon Valley may have exposed thousands of local residents to the measles at locations including Stanford, the Apple Visitor Center and several popular restaurants.

The adult visitor was not identified by name, but health officials released a long list of locations in Santa Clara County where the person visited during a recent stay in the valley.

The patient is an adult exposed to measles overseas, not in the Bay Area. They were hospitalized, officials said, as a result of their illness. Further information about the individual will not be released for reasons of medical privacy.

“Individuals who are not immune to measles and who visited the sites below at the dates and times indicated may be at risk of developing measles due to exposure,” the officials warned.

“People present at these sites who are not immune to measles may be at risk of developing measles and should watch for symptoms of the illness,” the warning continued. “Common symptoms of measles include fever, cough, runny nose, red eyes, and a rash, which can appear 7 to 21 days after the exposure.”

Health officials said if you develop these symptoms, call your doctor right away.

“The good news is that most people living in Santa Clara County have been vaccinated and are protected from measles,” said Dr. Sara Cody, County Health Officer and Public Health Department Director. “However, if you or a family member are not immune to measles and you think you were exposed to measles, watch closely for fever, cough, red eyes, runny nose and a rash that starts on the face. Call your doctor right away if you develop any of these symptoms.”
