Two unrelated cases of measles have been confirmed by county public health officials.
The county says both people who got the measles travel to San Diego for work.
One of the cases involved public exposure. Health officials say the infectious person, who did not have proof of measles vaccination, spent time at the Marriott Marquis Marina Hotel on West Harbor Drive on May 17th and at a Baskin Robbins on Palm Avenue in Imperial Beach on May 20th.
County Immunization staff are working with the Marriott Marquis to identify and follow up with potentially exposed employees and hotel guests.
Except for a measles case in an out of state visitor in March, there have been no other confirmed cases in San Diego County.
