What should you do if you were exposed to measles?
Check immunization records
Make sure you and your family are up to date with measles vaccines (MMR or MMRV).
- Most people need two doses if born in 1970 or later
- People born before 1970 are usually considered protected
- Check your immunization records or ask your health care provider to confirm
Watch for symptoms
Measles symptoms can appear up to 21 days after exposure. Even if you are vaccinated, stay alert for:
- Fever
- Cough, runny nose, red eyes
- Rash that starts on the face and spreads
If you are not vaccinated, avoid contact with:
- Pregnant individuals
- Young children
- People with weakened immune systems
Call before visiting a health care setting
If you think you have measles, were exposed, or are a close contact, call before visiting a doctor, hospital, clinic or any other health care setting. This helps protect others and allows health care providers to prepare for your visit.
Vaccination
The best way to protect against measles is vaccination. Two doses of measles-containing vaccine (MMR and/or MMRV) is 99 per cent effective in preventing a measles infection.
The measles vaccine is a publicly funded, routine childhood vaccine in Ontario. Check your immunization records or ask your healthcare provider to confirm your vaccinations.
