Toronto Public Health is alerting the public that individuals who attended a concert at the Coca-Cola Coliseum on April 1 may have been exposed to measles.

The potential exposure is linked to a visitor who was at the venue between 5:30 p.m. and midnight. According to the venue’s website, contemporary Christian artist Forrest Frank performed that evening.

Attendees are advised to monitor for measles symptoms until April 22. These symptoms include fever, runny nose, cough, red eyes, a red rash that typically starts on the face and spreads, and small blue-white spots inside the mouth and throat.

Anyone experiencing symptoms is urged to seek medical care promptly and to notify the clinic or hospital in advance to help prevent further spread.
