Respiratory Illness Data Tools

Use the following tools to learn more about respiratory illness activity locally, provincially and across Canada.

2023-24 Respiratory Season

Integrated Respiratory Virus Risk Indicators for Ontario: March 24, 2024 to April 6, 2024 is the final provincial report for the 2023-24 respiratory season.

Publishing of these provincial data will resume next season. For summary information on COVID-19, influenza, RSV and other seasonal respiratory viruses, please visit the Ontario Respiratory Virus Tool (information below).

Tracking respiratory activity in Huron and Perth Counties

Publishing of Huron Perth respiratory illness activity has also concluded for the 2023-24 season. Surveillance data will be published for the 2024-25 respiratory illness season beginning in the fall of 2024.

The health system’s readiness and response planning for respiratory illness season, including surveillance and vaccination efforts, is part of a regular annual cycle.  [ Seasonal Respiratory Pathogens Readiness and Response Planning Guide | Ontario Ministry of Health] 

This planning cycle typically runs from the first of September in the current year until the end of August the following year. (For example, Sept. 1, 2023 – Aug. 31, 2024). For the 2023 – 2024 season, the cycle started Sunday August 27 (week #35).

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. In this tool you can find:

  • Weekly case trends
  • Laboratory testing
  • Outbreaks

The tool also contains additional COVID-19-specific data including:

  • Outcomes (hospital admissions, deaths)
  • COVID-19 vaccine coverage (up to December 2, 2023, after which vaccine data are not being updated).

Gathering Surveillance Data

HPPH receives information about influenza and COVID-19 activity in the following ways:

  • Lab-confirmed cases submitted through local doctors and hospitals
  • Outbreaks at local hospitals, long-term care homes and other facilities

Because not everyone is eligible for influenza or COVID-19 testing, the number of lab-confirmed cases of either virus is only a small portion of people who may actually have influenza or COVID-19.

The number and trend of lab-confirmed cases being is a reflection of the level of influenza and COVID-19 activity in Huron and Perth, however, the actual number of  cases in our region is likely higher.
