Measles is a highly contagious virus spread through coughing and sneezing that can live for up to two hours in the air. Symptoms of measles include fever, a red blotchy rash, red watery eyes and Koplik (white) spots in the mouth. Measles is prevented by vaccination. Children in Ontario receive two doses of measles-containing vaccine before the age of 7. Endemic measles has been eliminated in Canada; however, imported cases continue to occur.
To obtain or inquire about an immunization record, or for general immunization information, please contact your local public health unit.
