One person in Long Beach was confirmed to have contracted the disease after visiting Disneyland between Dec. 15 and Dec. 20, said Dr. Mitchell Kushner, Long Beach's city health officer.
Two people in San Bernardino County were also diagnosed with measles. Officials from the county's Department of Public Health declined to release further information other than the cases are "in conjunction" with those arising from Disneyland and Disney's California Adventure theme parks.
It's unclear if either of the two people from San Bernardino County visited the parks or were exposed to measles by those who visited and became infectious.
Between Dec. 15 and Dec. 20, visitors to the Anaheim theme parks may have been exposed to measles, according to California's Department of Public Health.
The three new cases bring the statewide total up to 22 as of Monday, plus at least two confirmed cases in Utah and one each in Colorado and Washington.
Measles has been confirmed in Riverside, Los Angeles, Alameda and San Diego counties, with Orange County having eight cases as of Friday. One case was reported in Ventura County, state officials said.
Of those diagnosed, 12 were unvaccinated and four were vaccinated, state officials said. Six others either had no records of their vaccination or didn't know their vaccination status.
Nine others are being monitored for measles symptoms. Of those, five have no known links to the Disney outbreak.
