Waterloo Region – Region of Waterloo Public Health has been advised of a case of measles at the “Bachman-Turner Overdrive: Back In Overdrive 2025” concert at the Kitchener Memorial Auditorium on Thursday, April 24, 2025.   

Members of the public may have been exposed at the concert on the dates and times specified below:  

• Kitchener Memorial Auditorium, 400 East Ave., Kitchener, ON N2H 1Z6, from Thursday, April 24, 2025 at 6:00 p.m. to Friday, April 25, 2025 at 1:00 am.   

Anyone 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.    

Use the measles exposure self-assessment tool on Public Health’s website, www.regionofwaterloo.ca/measles.   

• Contact your local public health unit immediately if you fall into one of the following categories. Waterloo Region residents should call 519-575-4400.     

• • Immunocompromised people    
  • Pregnant people  
  • Infants less than one year of age     

• 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.   

• 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.   

• For those persons who worked and attended the concert and are not fully immunized: For this particular exposure, Public Health will be augmenting its supports by offering an additional measles immunization clinic on Wednesday April 30, 2025 from 10 a.m. to 4 p.m. in the Kitchener Aud parking lot. No appointment is required, please bring a copy of your immunization record if possible.    

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.
