The Middlesex-London Health Unit is alerting the community that between the hours of 10:43 pm on February 28 and 1:10 am on March 1, 2025 patients in the Adult Emergency Department at Victoria Hospital may have been exposed to a case of measles.

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 thinks they have measles should 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. Measles is very contagious and spreads through droplets in the air. One infected person can easily and unknowingly spread the virus to an entire room of people.

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 two doses of measles vaccination (listed 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.
