SAN JOSE - A person who tested positive for measles after returning from out of the country may have exposed others to the disease, according to Bay Area public health officials.

After passing through an unspecified U.S. airport, the person visited the H Mart at 1710 Oakland Road in San Jose between 7:15 p.m. and 9 p.m. on May 21, the Starbucks at 35040 Newark Blvd. in Newark between 11:45 a.m. and 2 p.m. on May 23 and the Trader Joes at 1306 Great Mall Parkway in Milpitas between 4:45 p.m. and 8 p.m. on May 25, the Alameda and Santa Clara county public health departments said in a news release.

Members of the public may be at risk of getting measles if they visited the sites at those times and are not immune to the disease or are unsure whether they were vaccinated.

Anyone who meets that criteria should review their immunization records to see if they are protected; call their health care provider if they are pregnant, the parent of an infant, have a weakened immune system or are unimmunized; and monitor for symptoms for seven to 21 days after the day of potential exposure, according to health officials.

Symptoms of the disease include fever, cough, runny nose, conjunctivitis and a rash, which usually appears 10 to 21 days after exposure. Health officials urged anyone with symptoms to call ahead to their medical facility before seeking treatment.

Health officials said the infected person may have been exposed to the disease at the airport. They were not hospitalized and are isolating at home, according to health officials.

The public health departments are planning to share additional information about the case at a news conference Friday.
