Measles Exposures in Ontario

Ongoing measles transmission in Ontario is impacting multiple public health units. Detailed information on measles cases in Ontario can be found in the Measles in Ontario Enhanced Epidemiological Summary.

For each measles case reported in Ontario, a public health investigation is completed to identify places where people may have been exposed to the measles virus.

Individuals who are not protected against measles AND who were in places where they may have been exposed to a case of measles on the following places and dates of possible exposure should check the website for their local public health unit for more information.

Getting vaccinated is the best way to protect yourself against measles.

In response to the current outbreak, in addition to routine immunizations, some public health units are offering early doses of measles vaccine (i.e., a dose of MMR vaccine for infants 6 to 11 months; a second dose of measles-containing vaccine before the age of 4) in affected regions and communities where the risk of exposure to measles is higher. Please see Routine and Outbreak-related Measles Immunization Schedules for more information.

The information on this webpage is updated on Tuesdays and Fridays, or the next business day following a holiday. Please check your local public health unit website for updated information.

On this page:

Places and dates of exposure to a case of measles

Places visited by recent measles cases while infectious have been identified. Individuals who were in the following places during the dates and times specified should contact their local public health unit if they are not protected against measles. See the section What to do if you are exposed to measles to find out more.

These exposure sites have been compiled from public advisories issued by public health units and will be updated regularly, as the information may change as new cases are identified and current exposures become out of date. Please note: this list includes only known exposure sites and there may be sites that have not yet been identified.

What is measles?

Measles is a respiratory infection that is highly contagious. Individuals with measles spread the virus by coughing or sneezing into the air. It can also be transmitted by touching your eyes, nose, or mouth after touching an infected surface. Symptoms of measles include fever, cough, runny nose, red watery eyes, and a red blotchy rash.

What to do if you are exposed to measles

If you are protected against measles, it is very unlikely that you will develop the disease. As a precautionary measure, watch for the onset of measles symptoms until 21 days after the date of exposure (see Places and dates of possible exposure to a case of measles) to find out more.

People are considered protected if they have at least one of the following:

  • Proof of vaccination with two valid doses of measles-containing vaccine (e.g. MMR vaccine)
  • Blood work showing antibodies to measles
  • Documentation of prior laboratory-confirmed measles infection
  • Are born before 1970 (with the exception of health care workers)
    • All health care workers require evidence of vaccination with two valid doses of measles-containing vaccine or bloodwork suggestive of immunity (measles IgG reactive) regardless of year of birth

If you do not have any of the above, you are not protected against measles.

If you think you have been exposed and you are not protected against measles or if you are unsure about your immunization history:

  • If you attend or work at a school, childcare, or healthcare setting, you MUST stay home and contact your local public health unit for further direction.  
  • If you have had no doses of MMR vaccine, stay at home and contact your local public health unit for further direction.
  • If you have had one dose of MMR vaccine, call your healthcare provider or local public health unit to receive an additional dose of MMR vaccine. Notify your healthcare provider of your exposure so that they can take appropriate precautions to limit the spread of measles. Unless you work in a healthcare setting, you can immediately return to work, school, or daycare after you get a second dose of measles-containing vaccine.
  • If you (or a family member) are at high risk of complications as listed below, contact your healthcare provider or local public health unit to discuss options to reduce the risk of measles infection through vaccination or a product called immunoglobulin. For these to be effective, they must be given very soon after exposure.
    • Babies under one year age who have not received measles vaccine
    • People with a severely weakened immune system
    • Pregnant individuals who are not protected against measles
  • If you are uncertain about your vaccination status, call your healthcare provider or your local public health unit to determine if you have received an MMR vaccine in the past.
    • If you develop symptoms and need medical care, call ahead before you visit the doctor, clinic, or hospital to inform them of your exposure to measles so they can prepare for your arrival and take appropriate precautions.
    • If you develop symptoms and do not need medical care, call your local public health unit.
