PLUMAS COUNTY, Calif. — Four cases of measles were reported in California over the past five days, with three of the four people having visited Disneyland recently, according to public health officials.

Plumas County Public Health officials called on community members to watch out for measles symptoms if they or someone they know went to Disneyland around Jan. 28. 

Officials said they were notified about the cases by the California Department of Public Health, adding that one of the cases lives in Shasta County. 

Local health departments are working to find anyone who might have been exposed to help prevent spread.

Measles symptoms include a rash that usually starts on the face, near the hairline, and behind the ears, and then spreads to the rest of the body along with high fever, cough, runny nose, and red, watery eyes. Symptoms usually appear 11 to 12 days after a person is exposed to the virus, but it can be anywhere from 7-12 days. 

The measles vaccine is considered safe and effective, with people needing two doses for strong protection.
