The HCA has been working with the facilities listed above to contact people who may have been
exposed to these cases and who are at increased risk of severe outcomes, such as infants,
pregnant women, and those with compromised immune systems.

People who were in the location(s) above around the same time(s) should:

  • Review their vaccination history if they have not previously had measles. People who have not had measles or the measles vaccine should talk with a health care provider about
    receiving Measles, Mumps and Rubella (MMR) vaccination.
  • Monitor themselves for illness with fever and/or an unexplained rash from 7 days to 21 days
    after their exposure (the time period when symptoms may develop); if symptoms develop,
    stay at home and call a health care provider immediately.

Residents with questions related to measles or potential exposure may also call the HCA Health

General Measles Information

Photo Source: CDC:

Measles is a highly contagious and potentially severe disease that causes fever, rash, cough, and red, watery eyes. Measles spreads very easily by air and by direct contact with an infected person. Measles is contagious from approximately 4 days before the rash appears through 4 days after the rash appears. Exposed people who have not had measles or been vaccinated generally develop symptoms approximately 8-12 days after exposure to measles, with rash appearing an average of 14 days but up to 21 days after that of the initial case.

Measles was eliminated from the United States in 2000, meaning that ongoing continuous transmission no longer occurs here. However, measles cases can still be imported from areas that have measles circulating and can spread quickly in communities with unvaccinated persons. Maintaining high vaccination rates is vital to preventing outbreaks of disease in our community. 

A safe effective vaccine is available to prevent measles and is part of the combination MMR (measles, mumps, rubella) vaccine.  Two doses are recommended for all children with the first dose routinely at 12-15 months and the second dose at 4-6 years.  Adolescents and adults who have not been vaccinated or had measles should also receive MMR.  Age appropriate vaccination against measles is required for child care, preschool, and grade school entry in California.


Measles is immediately reportable in Orange County, even if the case has not yet been confirmed but is suspected.  To report a case, health care providers/facilities should call OCHCA Epidemiology at 714-834-8180.   Zero to three (0-3) cases of measles are generally reported each year in Orange County, associated with exposure outside the County.  However, Orange County had outbreaks of measles in 2014 and 2015, and actually was in the forefront of the 2015 multi-state outbreak linked to Disneyland.
