The passenger tested positive for measles in Alberta. Public health officials in Alberta issued an alert through the Canadian Network for Public Health Intelligence on November 28.

People born after 1970 should have received two doses of a measles vaccine. It is often given as combined measles, mumps and rubella vaccine (MMR) or combined with chickenpox vaccine (varicella) vaccine (MMRV).

Those who have received only one dose of measles vaccine and are born after 1970 should obtain a second dose of vaccine. Those who were born prior to 1970 are likely to be immune due to prior measles infection.
