Plumas County Public Health has been notified by the California Department of Public Health that four cases of measles have been reported in the past five days in California. Three of the four people visited Disneyland around January 28, 2026. One of the cases lives in Shasta County.
Local health departments are working to find people who may have been exposed and to help prevent further spread. If you or someone you know went to Disneyland around that time period you should watch for measles symptoms (see below), especially if unvaccinated or have only had one dose.
Measles symptoms usually appear 11 to 12 days after a person is exposed to the virus but can be anywhere from 7-21 days.
What to Know About the Measles Vaccine
• The measles vaccine is usually given as the MMR vaccine (measles, mumps, rubella).
• MMR vaccine is safe and effective.
• People need two doses for strong protection.
• Two doses of MMR are about 97% effective at preventing measles
• Children usually get:
o A first dose at 12 months or older
o A second dose before kindergarten (or at least one month after the first dose)
• Some adults vaccinated before the 1990s may have received only one dose. Public Health encourages these adults to talk with their health care provider about whether they need a second dose.
• People born before 1957 are likely to already have immunity.
Symptoms:
Measles is more than just a rash. Symptoms may include:
• A rash that usually starts on the face, near the hairline and behind the ears, then spreads
to the rest of the body
• High fever (can be over 104° F)
• Cough
• Runny nose
• Red, watery eyes (conjunctivitis)
Measles is a very contagious virus. It can make people very sick and may lead to hospitalization or worse. People with measles can spread the virus from about four days before the rash appears to four days after the rash begins.
What to Do If You Have Symptoms
To help stop the spread of measles if you think you may have it:
• Do not go out in public.
• Do not go to a clinic, hospital, or doctor’s office without calling first.
• Call your health care provider if you have symptoms and tell them you are worried about measles: They can give you instructions on what to do next and help protect others from being exposed.
