COVID-19 testing patterns have changed over time. Current case counts includes reports of people tested with a molecular test (confirmed cases) and those tested by a health care provider using an antigen test (probable cases). Individuals testing themselves using at-home antigen tests are not included. Case counts represent only a portion of people with COVID-19 and should be interpreted with caution. Current case counts should not be compared to earlier parts of the pandemic.
Note: The number of deaths related to COVID and flu has not been updated on the dashboards since June 1, 2025, due to a temporary technical issue. The data will be updated as soon as possible.
