(CTV Montreal) — The MUHC is warning people that visited its Glen site between March 23 and 27 that they may have been exposed to measles.

In a release, the hospital said that an employee with the virus worked at the site for that five-day stretch.

They are asking people who were present at the site during those dates to confirm their immunization status.

If they are not immunized, they should call the MUHC at 514-934-8007.

“Though the employee in question had limited contact with patients and staff during the incubation period, it is vital that we take all necessary measures to ensure the disease is not spread further within the MUHC,” said Dr. Marie-Astrid Lefebvre, MUHC Infectious Diseases Specialist, in the statement.

“For the moment, there is no evidence that the disease has been transmitted to other people, but we will continue to monitor the situation closely until the end of the incubation period. In addition, we are reassured that the vast majority of people exposed are most likely immune to the measles virus.”

Symptoms of measles include fever, cough, runny nose, stuffy nose, red eyes, and tiny, white spots in the mouth.
