Durham Region’s health department has confirmed measles in an unimmunized child who recently travelled internationally and is warning of possible public exposure, CBC reported Saturday.

The department said it is investigating and contacting people known to have been in contact with the child. People who may have been exposed are being asked to monitor for symptoms until Nov. 24.

Residents who believe they were exposed should confirm they have received two doses of measles vaccine, the department advised. Anyone who develops symptoms should stay home, call ahead before visiting a clinic or primary care provider, and wear a well-fitted mask when getting a medical assessment.

Symptoms include high fever, cough, runny nose, red and watery eyes, sensitivity to light, and a red rash lasting four to seven days. Symptoms typically develop seven to 21 days after infection, according to the department.

Measles is highly contagious and spreads easily among people who have not been vaccinated or previously had the disease. The virus can remain in the air and on surfaces for up to two hours, the department said.

Children younger than one, unimmunized pregnant people and people with weakened immune systems face an increased risk of complications.
