• Use the controls to select a virus and a measure of respiratory virus activity. The map displays selected data for the most recent surveillance week, presenting a geographic comparison of the current situation. Hover over or tap areas to display trends over time.

Figure 4: Data notes

• Different provinces and territories may use different testing practices which can affect indicators such as percentage of tests positive. Interpret with caution.
• Respiratory viruses other than SARS-CoV-2 are shown at the regional and national levels. Note that some regions do not test for/report on all RVDSS viruses.
• Weekly percent positivity estimates are suppressed (not shown) for the Northwest Territories when the number of weekly COVID-19 tests reported is under 45. For small counts such as this, it is difficult to provide an accurate weekly percent positivity estimate.
