About this data
It changes rapidly and may differ by location
This data changes rapidly and might not reflect some cases still being reported. Some areas may not have data because they haven’t published their data or haven’t done so recently. Because data availability differs by location, date ranges for 14-day data may start on different dates.

It shows positive tests, which differ from positive casesThe number of positive tests may not be equal to the number of positive cases because of reporting differences across locations. It's also common for a single person to take more than one test. This data uses reporting from polymerase chain reaction (PCR) and antigen tests.
