General Measles Information | |
|
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. |
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.
