CDPHE Links to the CO Exposure Notifications app and COVID-19 Resources

The Colorado Department of Public Health and Environment (CDPHE) has launched their CO Exposure Notifications service to help stop the spread of COVID-19.

One of the key tools to fight COVID-19 and slow its spread is right in your pocket. CO Exposure Notifications is a free and voluntary service developed in partnership with Google and Apple that can notify users of possible exposure to COVID-19. 

By opting in, your Android or iPhone device will share anonymous tokens with other CO Exposure Notifications users using your phone’s Bluetooth. If another user you’ve been near tests positive for COVID-19 within a 14-day period, the service will notify you. If you test positive, you can easily and anonymously notify others to stop the spread of COVID-19.

Tokens contain no personal information or location data and everything is completely anonymous.

Knowing about a potential exposure allows you to self-quarantine immediately, get tested, and reduce the risk to your family, friends, neighbors, coworkers and community.

Android users can download CO Exposure Notifications on the Google Play store

iPhone users can enable CO Exposure Notifications in their phone settings by finding Settings > Exposure Notifications > United States > Colorado.
