SANTA ANA, Calif. -- A New Zealand teenager who travelled to Southern California this month was infectious with highly contagious measles and may have exposed others at Disneyland and a nearby hotel, health officials said Friday.

The Orange County Health Care Agency said the exposures could have occurred Aug. 11 at the Desert Palms Hotel in Anaheim and on Aug. 12 at Disneyland and the Disney California Adventure Park. The girl remained in Southern California through Aug. 15 and has since returned to New Zealand, said Dr. Nichole Quick, the county's health care officer.

The agency said it has been working with the facilities to reach people who had close contact. There are no current reports that anyone has contracted measles from the teen, Quick said.

She said she expects to see more measles cases, generally, among international travellers who visit California because of an increase in the illness overseas.

"We're in general concerned with the outbreaks going on in places in this country as well as internationally," she said.

The teen also travelled to nearby Los Angeles County. A message left for that county's health care agency was not immediately returned.

Disneyland officials on Friday said no employees at the theme park were reported to have contracted the illness. Dr. Pamela Hymel, Disneyland's chief medical officer, said in a statement that health officials said the risk to employees and visitors "is likely low."

The park boosted an existing immunization program earlier this year for employees, she said.

Disneyland and adjacent Disney California Adventure Park are major tourist destinations, drawing tens of thousands of visitors a day.

In 2015, a measles outbreak involving Disneyland sickened 147 people and spread across the U.S. and into Canada.

As of early this month, Los Angeles County health officials reported 16 measles cases among county residents this year and 10 others among non-residents who travelled through.

The Orange County health agency says people who may have been exposed should monitor themselves for symptoms such as fever and rash occurring up to 21 days from exposure. Quick urged anyone who has symptoms to call their health care provider before going to the doctor to avoid additional exposures. People are also urged to check their records to determine if they have been vaccinated or previously had measles.
