Of the national chains with the most outbreaks of COVID-19 in Colorado, some seem to be doing a better job of keeping the virus at bay. But the number of outbreaks at others continues to grow, and so does the size of the outbreaks.
Just two chain outbreaks have spawned more than 100 cases each, while many others have infected dozens of staffers.
The Colorado Department of Public Health and Environment considers an entity an outbreak after two or more COVID-19 cases among residents, staffers or other people connected to a specific location are confirmed within a fourteen-day period, or two or more cases of respiratory illness with an onset of symptoms within a fourteen-day period are paired with at least one additional COVID-19 diagnosis. The vast majority of businesses and facilities identified as outbreaks remain open while working with the department to monitor symptoms and prevent future infections.
