The Middlesex-London Health Unit is alerting the community that on March 1, 2025 between the hours of 10:45 am and 3:00 pm, shoppers at the Value Village, 4465 Wellington Road South may have been exposed to a case of measles.

If exposed, the following individuals should call MLHU to discuss options for post-exposure measures for the measles virus:

• Individuals who are immunocompromised
• Individuals who are pregnant and not fully vaccinated for measles
• Infants under the age of 1

All individuals who were exposed should monitor themselves for symptoms for 21 days. Symptoms may include:

• Fever, cough and runny nose
• Red and irritated eyes
• Small white, grey or blue spots in the mouth
• Red, blotchy rash (which is the last symptom to appear).

Anyone who suspects they have measles should self-isolate at home to avoid spreading the virus to others. If medical care is required, they are asked to call ahead so that their health care provider can put precautions in place prior to their arrival.

“There are many active cases of measles across Southwestern Ontario, particularly in our neighbouring jurisdictions. Exposures to measles in the Middlesex-London region are expected. Those who are immunocompromised or unvaccinated are most at risk for serious illness,” says Dr. Janice Mok, Resident Physician for MLHU. “Vaccination is the most important protection and is safe and widely available.”

In general, those born before 1970 are considered immune against measles. Those born in or after 1970 should check their immunization records to make sure that they and their family members are up-to-date with measles vaccination (noted as MMR or MMRV in most records). Two doses are recommended for anyone born in or after 1970. Those who believe they are unvaccinated or under vaccinated should speak to their health care provider or a walk-in clinic about getting their immunizations up-to-date.
