Measles Exposure Alert at York Region Hospital
Public health officials warn of potential measles exposure at Mackenzie Health's emergency room on May 19. Residents who attended should verify vaccination status.
York Region Public Health issued an alert Friday after a confirmed measles case exposed anyone in Mackenzie Health Hospital's emergency room between 10:30 a.m. and 2:15 p.m. on Tuesday, May 19.
Measles is a highly contagious viral infection that spreads through respiratory droplets. Health officials are urging anyone who may have been present during that window to immediately confirm they have received two doses of the measles vaccine and to monitor themselves for symptoms including fever, cough, runny nose, and the characteristic rash.
York Region Public Health emphasized that vaccination is the most effective protection against measles. Those who cannot confirm two vaccine doses should contact their healthcare provider immediately. The alert serves as a reminder that measles, while preventable through vaccination, remains a public health concern — especially as travel and gatherings increase heading into summer.
Residents with questions or concerns should contact York Region Public Health directly for guidance on vaccination status and next steps.
