Breaking News: Measles Outbreak in Waterloo Region Hits 14 Cases and Counting!

The Region of Waterloo Public Health has confirmed a rise in measles cases, with the total now reaching 14. This alarming increase sparks concerns about public health as the region faces additional public exposure risks.

A recent exposure incident took place on Saturday, March 29, 2025, at the Grand River Hospital’s Emergency Department in Kitchener, Ontario. The exposure window lasted from 4 p.m. to 7 p.m. Current updates indicate that the hospital has been rebranded as WRHN @ Midtown since April 1, 2025.

Dr. Rabia Bana, the Associate Medical Officer of Health, highlighted that the majority of these cases involve unimmunized individuals. “Given the highly contagious nature of measles, we expect this number to continue to rise,” she said, urging everyone to take the situation seriously.

Public Health officials are actively working to identify individuals who may have been in contact with confirmed cases. To protect yourself and others, individuals who were potentially exposed are advised to follow these crucial steps:

Steps to Take if Exposed:

1. **Contact your local public health unit** if you fall into any of the following categories: - Immunocompromised individuals. - Pregnant women. - Anyone (children or adults) born in or after 1970 who are unvaccinated or have received only one dose of the measles vaccine.

Waterloo Region residents can reach the public health line at 519-575-4400 for assistance and guidance about potential post-exposure measures.

2. **Review your vaccination status.** The measles vaccine may appear on your records as "MMR", "MMRV", or simply "M". It is critical to confirm your immunity status: - Individuals born before 1970 are generally considered immune. - Those born in or after 1970 who have received two doses of the vaccine are typically protected from measles exposure.

In Ontario, children are recommended to receive two doses of the measles vaccine by age seven, but some may have only had one. If unsure, it's essential to consult your healthcare provider.

3. **Be on the lookout for measles symptoms.** Symptoms can manifest from 7 to 21 days post-exposure. Early signs include fever, cough, runny nose, and distinctive white spots in the mouth. Within days, a red, blotchy rash usually starts on the face before spreading downward.

Residents can use the measles exposure self-assessment tool available on the Region of Waterloo's website for further guidance.

If you suspect you have measles, contact your healthcare provider before visiting in person. This helps ensure the safety of others in waiting areas and treatment facilities.
