ABC News reports that a teenager from New Zealand who visited Disneyland, Universal Studios, and other tourist spots around Los Angeles had measles and may have exposed others.
Public health agencies say the girl arrived at LAX on August 11. She traveled to Disneyland and other attractions through August 15.
The girl has since returned to New Zealand, and authorities say there are not yet any reports of anyone contracting measles from interacting with her.
The agency is working to contact people who had close contact with her.
Orange County's health care officer Dr. Nichole Quick, said that she expects to see more cases of measles generally among international travelers because of an increase in the illness overseas.
Officials say people who may have been exposed should monitor themselves closely for symptoms such as fever and rash that occur up to 21 days from possible exposure.
