The first case of measles this year in San Diego County has been confirmed in an 11-month-old infant, county health officials said Wednesday.

The County of San Diego Health and Human Services Agency said the unimmunized infant recently traveled to the Philippines and is currently hospitalized.

The county said the baby may have exposed others while seeking care at the following locations:

  • Kaiser Permanente Otay Mesa Medical Offices, 4650 Palm Ave., San Diego, CA 92154 on the following dates and times: July 29 from 6 p.m. to 9 p.m. in the Pediatric Clinic; Aug. 4 from 8:30 a.m. to 12:30 p.m. in the Pediatric Clinic, Urgent Care and Pharmacy; and Aug. 5 from 4:45 p.m. to 9:30 p.m. in the Pediatric Clinic.
  • Kaiser Permanente San Diego Medical Center, 9455 Clairemont Mesa Blvd., San Diego, CA 92123: Aug. 5 from 8 p.m. to 10 p.m. in the Emergency Department.

HHSA is working with Kaiser Permanente to identify and follow up with patients and staff who may have been exposed at those locations to check if they have been vaccinated and their potential for developing measles.

“Measles is a very contagious disease that can be spread easily by coughing, sneezing or being in the same room with an infected person,” said Wilma J. Wooten, M.D., M.P.H., County public health officer. “Anyone who was at any of these specific locations at the dates and times listed above should watch for symptoms and call their health care provider if they show any signs of the disease.”

People with symptoms are asked to telephone their doctor’s office in advance, rather than visit an office directly, so that infection control measures may be activated to prevent exposure to others.
