Canada eliminated measles back in 1998 through widespread vaccination programs. Here, the vaccine is given to children astwo doses of a combined shotthat also protects against a combination of infections either measles, mumpsand rubella, or measles, mumps, rubellaand varicella.

The annual case count remains small only a dozen confirmed infections were reported country-wide in 2023 and most cases are now acquired through travel outside the country.

But clinicians say outbreaks are still a risk. Measles spreadeasily between those who haven't been vaccinated or haven't previously had measles, public health said.

Symptoms begin one to three weeks after infection and include a high fever over 38.8 C, cough, runny nose, drowsiness, irritability, red, watery eyes, small white spots with white centres on the inside of the mouth and throat, and a red, blotchy rash.

Infants under one year of age, pregnant people and people with weakened immune systems are at an increased risk of severe complications.

People who think they may have been exposed to the measles virus should:

• Contact public health.
• Check immunization records of themselves and their family members to see if they are up-to-date on their measles vaccinations. Two doses are recommended for anyone born after 1969.
• Watch for symptoms, even if they've been vaccinated.
