LOS ANGELES (AP) - California health officials say a measles outbreak that originated at Disneyland has grown to 99 cases in the state.
The California Department of Public Health said Wednesday two-thirds were infected when they visited Disney theme parks last month or had contact with a sick person who went there.
Health officials say it's unknown how the others got measles. Measles cases also have been confirmed in half a dozen states and Mexico.
Doctors say the best way to prevent measles is to get vaccinated against the highly contagious virus, which spreads easily through coughing or sneezing. Most of those infected in the latest outbreak were adults who weren't vaccinated.
While the U.S. has not seen homegrown measles in years, outbreaks still occur when people travel overseas and bring the virus back.
