Gov. Jared Polis extended Colorado’s statewide mask mandate for another 30 days in an executive order signed Tuesday.

The order, previously set to expire around Dec. 10, will now be in effect until Jan. 7.

This is the sixth time the statewide mask order has been extended since it came out on July 16. The state’s first mask order was issued on April 15, requiring only essential workers to wear face coverings.

“We have learned that widespread mask use is a low cost and highly effective way to reduce the spread of COVID-19 infections by as much as 65%,” the order reads.

“Broad adoption of mask wearing in Colorado may have significant economic benefits by allowing the State to prevent re-closures of businesses and schools and, ultimately, return to our normal lives more quickly.”

One in 40 Coloradans are currently contagious with the coronavirus, according to the Colorado Department of Health and Environment.

Total cases in Colorado have reached 268,589, including 3,411 new cases reported Tuesday alone. The state’s two-week cumulative incident rate is at 1,043 per 100,000 population.
