About This Dashboard

A test represents at least one specimen tested per person per day. If a person received more than one test in a day, that person is only counted once per day.

The test positivity rate is calculated as the percent of total tests performed that are positive. Due to the preliminary nature of the most recent data, test positivity rate data in this dashboard is presented with a 7-day lag.

The 7-day average positivity rate represents the most recent positivity rate averaged over the prior 7 days.
