DENVER — As Colorado's positivity rate and hospitalizations have declined, so has the number of COVID-19 outbreaks reported to the state.
At the peak of the third wave of heightened novel coronavirus activity in Colorado, there were nearly 1,300 active outbreaks. This week's report from the Colorado Department of Public Health and Environment (CDPHE) shows 982 outbreaks listed as active and another 2,352 listed as resolved.
Two cases of the novel coronavirus constitute an outbreak, and the numbers are cumulative, meaning if an entity has a certain number of cases, that doesn't mean all those people were sick at once.

For an outbreak to be resolved, CDPHE said 28 days must pass with no new illnesses.
The largest active COVID-19 outbreaks are at colleges and prisons. Other outbreaks have been reported at retailers like Home Depot and Target, grocery stores, ski areas and more.
