COVID-19 Testing

Weekly testing data is updated on Thursdays. Testing data for the most recent week are incomplete and may change in future updates.

Given the changes to testing guidance, the percent positivity estimates are now separated into before (2020 & 2021) and after (2022 & 2023). Data for these two time periods should not be compared.

Summary

  • There were 28.5 new COVID-19 tests per 10,000 population in Simcoe County and 17.0 tests per 10,000 population in Muskoka District for the most recent week (January 22). 
  • The percent positivity rate for the most recent week (January 22) in Simcoe County is 14.1% and 8.25% in Muskoka District.
  • Testing rates declined from mid-September to early November but have stabilized over the most recent weeks. Percent positivity has been decreasing since the holidays.
