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). Data for these two time periods should not be compared.
