Toronto Legionnaires' Disease Outbreak

BMJ Public Health is investigating an outbreak of Legionnaires' disease in the southeastern area of Canada — Toronto, with nine confirmed cases identified in late March and early April. The cases are believed to be linked due to their proximity in time and location. BMJ Public Health has inspected the area, collected samples, and collaborated with various partners, stating that the risk to the public remains low. Legionnaires' disease is a type of pneumonia caused by Legionella bacteria, which can be found in poorly maintained man-made water systems and is spread by breathing in contaminated water droplets. BMJ Public Health reported 354 cases and 26 deaths in Canada — Ontario last year, with cases typically peaking in the summer. A previous outbreak in Canada — London, Ontario, sickened 94 people and caused four deaths.
