Ontario Respiratory Virus Tool
The Ontario Respiratory Virus Tool provides comprehensive epidemiological information of respiratory virus activity in Ontario, including COVID-19, influenza and other respiratory viruses. Explore respiratory virus data including weekly case trends, laboratory testing, and outbreaks. The tool also contains additional COVID-19-specific data including: outcomes (hospitalizations, deaths, and ICU and hospital bed occupancy) and COVID-19 vaccination and dose administration.
- COVID-19 vaccine coverage data is no longer updated. View COVID-19 vaccines data up to December 2, 2023 in the ‘COVID-19 Vaccines’ tab.
- For the week of December 3 to 9, 2023 (Week 49), Ontario surpassed the 5% positivity threshold, indicating the start of seasonal influenza activity in the province.
- Due to data reporting delays in the provincial Case and Contact Management (CCM) system where PHO pulls the data from, please interpret COVID-19 death and hospitalization data from November 26, 2023 onwards with caution. View our technical notes for more information about the ORVT’s data sources.
The tool is updated Fridays. The tool will be updated the next business day following a holiday.
