Respiratory Virus Surveillance
Please Note: Weekly updates for the 2024/25 respiratory season concluded on May 28, 2025 and will resume in Fall 2025 for the 2025/26 respiratory season.
The Weekly Respiratory Virus Update is an interactive dashboard that is updated weekly, usually on Wednesday mornings, for the respiratory virus season to date (September 1 to end of May). It describes the most recent week’s local influenza, COVID-19 and RSV activity throughout the respiratory season, providing an overview of circulating respiratory viruses in Simcoe Muskoka and Ontario (where available).
Annual surveillance data for COVID-19 and Influenza are available as part of the Infectious Diseases dashboard.
