Anyone who believes they may have been exposed to the measles virus at the above locations should do the following:
- Confirm you and your family members have two doses of measles vaccine (MMR or MMRV); those born before 1970 would likely have had measles illness as a child and are protected. Individuals who are unsure of their vaccination status should check with their health care provider.
- If you develop symptoms, stay home and do not attend work or school. Call ahead before visiting a clinic or a primary care provider and let them know you may have measles to allow them to prepare and prevent the spread of the virus. Wear a well-fitting mask when getting a medical assessment.
- Individuals with questions about airport exposures should contact their local public health unit or Health 811, the provincial health help line.
