Active coronavirus outbreaks at Colorado retailers, ski resorts, grocery stores and more

The number of active COVID-19 outbreaks in Colorado has decreased since December.

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.
