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