More than 80 COVID-19 outbreaks were resolved in Colorado over the past week, cutting the total number of clusters by a third.

There now are 152 active outbreaks in Colorado, the lowest number of clusters since Sept. 16 and just the third time the state has dipped below 200 since the end of September, according to data released weekly by the Colorado Department of Public Health and Environment.

It keeps pace with several weeks of consistent declines, which have plummeted since early May as the vaccination levels improve.

Making direct comparisons to previous months comes with a caveat: The health department earlier this month revised its definition for most outbreaks, raising the number of cases needed to qualify. That didn’t resolve existing small outbreaks, but it will limit which ones can now qualify.

Still, the dipping numbers come alongside a general COVID-19 decline statewide. Though pockets such as Mesa County are far above the state as a whole, Colorado’s situation has dramatically improved over the past two months.

In late April and early May, the state was teetering into a fourth wave, after weeks of nearly constant declines in cases, hospitalizations and outbreaks.

But climbing vaccination rates flattened the curve, and Colorado has regularly posted its lowest COVID-19 case rates in nearly a year.
