Isolation and Quarantine Guidance


Should you have questions about being exposed to COVID-19 or about how to isolate after testing positive for COVID-19  please call  720-412-9503 or email [email protected]


If you have tested positive for COVID-19, OR if you develop symptoms, follow these instructions. These instructions are for people who have been told to isolate or who are voluntarily isolating due to symptoms.  A person’s residence is the preferred setting for isolation.

Isolation or self-isolation includes people who:

  • Have a positive COVID-19 test.
  • Have symptoms of COVID-19.
  • Are getting ill and think they might have COVID-19. Symptoms, 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.


  • separates sick people with a contagious disease from people who are not sick.
  • Is for people who are already sick.
  • Can be voluntary, but public health agencies have the legal authority to issue isolation orders to sick people.

For additional information on isolation please visit covid19.colorado.gov/how-to-isolate


Quarantine is an important strategy for reducing the spread of COVID-19 after you have had close contact with someone who has COVID-19.

Exposure to COVID-19
Exposure happens when you have close contact with someone who has COVID-19. Close contact means you have been within six feet of an infected person for a total of 15 minutes over a 24-hour period. That doesn’t have to be 15 minutes in a row. If you were close to an infected person for 5 minutes in the morning and 10 minutes in the afternoon on the same day, you’ve had close contact with someone with COVID-19

What is quarantining?

  • Quarantining prevents the ongoing spread of the virus to other people by individuals who know they have been exposed or are likely to have been exposed, but do not yet know if they have been infected. It’s a precaution and an effective tool to prevent viral spread since people infected with COVID-19 can be contagious even without having symptoms.
  • Quarantining can be voluntary, and people should self-quarantine if they have known exposure and do not know whether they have been infected.  Colorado also has the legal authority to issue quarantine orders to people who were exposed to a contagious disease. This will not occur in most cases and is reserved for circumstances where it is difficult for people to voluntarily quarantine.

For additional information on how long should quarantining last, what to do if you get sick, and what you should do if you are in quarantine – please visit covid19.colorado.gov/how-to-quarantine
