SEHU Urges Residents: Check Your Measles Vaccination Status Amid Ontario Outbreak

While no cases locally, Ontario has reported 177 cases.

The South East Health Unit (SEHU) is encouraging residents to check their measles vaccine status and be aware of symptoms as Ontario faces a multi-jurisdictional measles outbreak.

As of February 26, 2025, Ontario has reported 177 cases (127 confirmed, 50 probable), with outbreaks in four public health units: Southwestern Public Health, Grey Bruce Health Unit, Grand Erie Public Health, and Chatham-Kent Public Health. No cases have been reported in SEHU’s jurisdiction at this time.

The MMR vaccine is part of Ontario’s routine immunization schedule and is required for children attending school unless exempt. Individuals born before 1970 are generally presumed immune, but those born later should ensure they have received two doses. High-risk groups, including health-care workers, post-secondary students, and travelers, may require additional vaccination.

Symptoms of measles appear 4-14 days after exposure and include fever, cough, runny nose, red eyes, and rash. Anyone experiencing symptoms or potential exposure should contact their health-care provider, wear a mask, and avoid public settings.
