Health officials in California have announced that the measles outbreak that started at Disneyland is officially over.
The outbreak began at the theme park in December, and measles infected 131 people in California. The disease eventually spread to seven other states as well as to Mexico and Canada.
Many of the people infected with measles weren't vaccinated against the disease, The Associated Press reports. And while the Disneyland outbreak may be over, the U.S. also has other outbreaks that aren't related to the one at Disneyland.
"We are pleased this outbreak is over, but caution that measles can be reintroduced in California at any time when an infected person brings it to the state," Karen Smith, director of the California Department of Public Health, told The Los Angeles Times. "The best defense for protection against the highly infectious measles is vaccination."
