Measles is a highly contagious disease caused by a respiratory virus that spreads easily to those who are not vaccinated against measles or who have not previously had measles. Infants under one year of age, pregnant people, and people with weakened immune systems are at an increased risk of severe complications.
Measles symptoms begin 7-21 days after infection and may include:
- High fever of 38.8 C (101 F) or greater
- Cough
- Runny nose
- Drowsiness
- Irritability
- Red, watery eyes
- Small white spots with white centres, known as Koplik’s spots, on the inside of the mouth and throat
- Red, blotchy rash three to seven days after symptoms start
Anyone who believes they may have been exposed to the measles virus should do the following:
- Individuals who believe they have been in contact with a person with measles should contact Public Health Services at 905-546-6170 as soon as possible to speak with a Public Health Nurse who can assess your risk of developing measles. Monitor for signs and symptoms of measles for 21 days after the date of exposure.
- Check their immunization record to confirm they and their family members are up-to-date with their measles vaccinations (MMR or MMRV). Those who are unsure are asked to check with their health care provider. Two doses are generally recommended for anyone born after 1969. In general, those born before 1970 are considered protected against measles.
- Even individuals who are up to date with the measles vaccine should watch for symptoms of measles.
