Region of Waterloo Public Health has been advised of a case of measles at Conestoga’s Doon campus.
Members of the public may have been exposed on the dates and times specified below:
Wednesday, May 21, 2025, from 2 p.m. to 6:30 p.m.
Conestoga College, Doon Campus
299 Doon Valley Dr., Kitchener
Doon Main Building (DMB), E-Wing - 2nd floor, Classroom 2E06
Given how easily measles spreads, those who were present in classroom 2E06, at Starbucks or in any other classrooms/corridors on the 2nd floor of the E-Wing on May 21, 2025, between 2:00 p.m. and 6:30 p.m. are at risk of getting sick with measles and passing it to others.
Region of Waterloo Public Health has been working closely with Conestoga to notify students and staff who should refer to the communication provided by the college to determine if they can attend school.
Members of the public who may have been exposed should follow these steps:
- Check your vaccination record. The measles vaccine is typically noted as “MMR”, “MMRV” or “M” on records. People who have been exposed to measles should confirm if they meet the following requirements for immunity:
- People born before 1970 likely had measles in the past and are generally considered immune.
- People born in or after 1970 are considered fully protected from a known exposure to measles if they have had two doses of measles vaccine.
- Most children receive two doses of measles vaccine by age seven based on the current routine vaccine schedule in Ontario.
- Some people born in or after 1970 may have only received one dose of measles vaccine as part of their routine vaccine schedule.
- Watch for symptoms of measles. These can appear up to 21 days after exposure but usually occur within 7-12 days. Symptoms include fever, cough, runny nose, white spots in the mouth, and red watery eyes that may be sensitive to light. A few days after symptoms begin, a red rash usually develops that starts on the face and spreads down the body.
- Use the measles exposure self-assessment tool on Public Health’s website, www.regionofwaterloo.ca/measles.
- If you think you have measles symptoms, call your health-care provider before you go for in-person care. This allows health-care staff to take the necessary precautions to protect others visiting the office, clinic or hospital.
Public exposures are added on an ongoing basis to the Region’s website.
Public Health Ontario also maintains a listing of potential public exposures across Ontario and a weekly update of case numbers across Ontario, which is updated every Thursday.
With the recent increase in measles cases across southwestern Ontario, the Conestoga community is encouraged to monitor public health guidance. Questions at the college can be directed to safety@conestogac.on.ca.
