Exposure Notifications ceasing operations May 11, 2023

Due to the end of the federal public health emergency, the Colorado Department of Public Health and Environment’s CO Exposure Notifications system ceased operations on May 11, 2023. A message will appear on users’ phones alerting them that the system is no longer operational and prompting them to delete their data. CDPHE will continue to send text messages to anyone with a reported positive COVID-19 test result that include a link to disease control information through July 2023, if their phone number is on file.

Receive a notification? Here’s what to do next: 

  • Get tested at least five days after the date of exposure (as indicated in the notification), or immediately if symptoms develop. Find a testing site
  • Wear a well-fitted mask around others at home, in public, and at work for 10 days from the date of exposure.
  • Watch for symptoms for at least 10 days from exposure. Begin isolation if you start to develop symptoms or test positive. Learn more about how to isolate.  
  • Notify others that you have been in close contact with since the date of exposure that you have received an exposure notification and that you are waiting for test results.

Tested positive? 

Begin isolation immediately if you test positive for COVID-19. Upload a code to the Exposure Notification service to let others you’ve been in contact with know they may have been exposed.

If you’ve tested positive or have started to feel symptoms, ask your health care provider about treatment as soon as you can. If you don’t have a provider, find a place to seek treatment using our treatments map. Treatment can help keep you from getting seriously sick and keep you out of the hospital if you take it soon enough. Some providers offer both testing and treatment in a seamless experience.

How do I know this notification is real?

An Exposure Notification will come as a push notification through the app (Android) or the phone (iPhone). You will never receive an Exposure Notification as a text message or phone call. Here’s an example of what the notification looks like:

As a reminder, the Exposure Notification program does not record any personal information or location data. Everything is completely anonymous. To learn more about the program, visit the Exposure Notifications page.


What does this notification mean? 

If you received an Exposure Notification, it means that you and your phone have been in close proximity to someone who uses the technology and tested positive for COVID-19. You may have been exposed to the virus.

I’m experiencing symptoms...

Symptoms of COVID-19, especially early on, may be mild and feel like a common cold. Early symptoms could include a combination of cough, body aches, fatigue, and chest tightness. Some people may not develop fever or fever may not appear until several days into the illness. If you are experiencing symptoms, you should get tested for COVID-19 immediately, even if you are fully vaccinated or previously tested negative. To find a testing site near you, visit the Testing for COVID-19 page. Seek emergency medical care immediately if you have trouble breathing, pain or pressure in your chest that doesn’t go away, blue-tinged lips or face, or other serious symptoms. Notify your provider that you were exposed to COVID-19.
