Mask Guidance

Mask-wearing and vaccination are the two most important tools residents can use to prevent the spread of COVID-19 and bring us closer to the end of the pandemic. Now that all Coloradans age 12 and older have access to safe and effective COVID-19 vaccines, masks are only required in certain places for people who are not fully vaccinated per CDPHE's Fourth Amended Public Health Order 20-38. Fully vaccinated people can go without masks in public indoor spaces unless the setting requires otherwise. 

However, as of July 27, 2021, the Centers for Disease Control and Prevention (CDC) issued new guidance recommending mask wearing for the general public, including those who are fully vaccinated, in areas where there is substantial COVID-19 transmission (defined by 50-99.99 new cases per 100,000 people in the past 7 days). Based on current COVID-19 incidence rates in Jefferson County (77.2 per 100,000 people as of July 28, 2021), Jefferson County is in the substantial transmission category. For this reason, JCPH strongly recommends that all residents ages 2 and older, regardless of vaccination status, return to wearing a mask in indoor public spaces to minimize risk and maximize protection from COVID-19, including the highly infectious Delta variant. 

Businesses may have their own mask restrictions. We encourage everyone to keep masks with them in public and wear them if asked. Everyone age 2 and older must still wear masks on planes, buses, trains and other forms of public transportation traveling into, within, or out of the United States, and in U.S. transportation hubs such as airports and stations. This is required by federal law for both vaccinated and unvaccinated people.

Quick Tips for Wearing a Mask

  • Choose a mask that has two or more layers of washable, breathable fabric and a nose wire to prevent air from leaking out of the top. 
  • Masks should completely cover your nose and mouth and fit snugly against the sides of your face without gaps. 
  • Wash your hands before and after putting your face covering in place. 
  • Do not touch the face covering again until you remove it. 
  • Remove your mask to eat and drink and if it is still in good repair, you may continue to use it.
