California health officials confirmed that 13 new measles cases are connected to an outbreak at Disney theme parks last month, bringing the total number of illnesses to 39.
The new cases of the airborne illness reported Thursday include eight in San Diego County and five in Los Angeles County.
The San Diego County cases include several people who showed up with fevers and rashes Wednesday at a health clinic in the suburb of La Mesa.
Officials said 35 of the confirmed cases are in California, two are in Utah and one apiece in Colorado and Washington.
Most of the patients visited Disneyland or Disney California Adventure between Dec. 15 and Dec. 20, but some contracted the illness from others who visited.
San Diego County health officials say only one of the patients there had been vaccinated. LA County vaccination numbers weren't immediately available.
