While international travel was the initial source of these outbreaks, all the people with recent measles infections were exposed to the virus in Canada.

The majority of measles cases reported in Canada occur among unvaccinated people, many of whom are children and include infants under the age of one who are more vulnerable and have not yet had the opportunity to be vaccinated… that is why we need to remain vigilant and I recommend that we keep up-to-date with the recommended vaccinations.
