Mobile Testing 

If you want a COVID-19 test, but are unable to access a testing site due to transportation, mobility, or financial limitations, we can come to you. Call 311 to find out if you qualify for a visit from the Wellness Winnie mobile testing unit. They will ask you some questions to ensure you meet the requirements, and then you’ll be scheduled for a visit.

The Wellness Winnie operates five to six days per week during normal business hours by a team of medical professionals and support staff.

What are the eligibility criteria for mobile testing?  What will they ask me? 

When callers reach 311 they will hear “if you are calling to see if you qualify for free mobile COVID-19 testing from the City & County of Denver, please press 7.”

In order to receive a free COVID-19 test you must meet the following criteria:

  1. You believe you have symptoms of COVID-19 or have been told by Public Health that you are a close contact of a positive COVID-19 case; and
  2. are unable to travel to a COVID 19 testing facility; and
  3. are a resident of the City and County of Denver.

If you can answer “yes” to these 3 items, please hold to speak to Denver Department of Public Health & Environment.” If you cannot answer “yes” to these 3 items, please hang up and go to for more information.

People who are undocumented are encouraged to get tested if they are symptomatic; ID is not required for our mobile testing program. We ask for name and DOB for records purposes – that is the only way we can confirm a person’s test results. If you are visiting another testing site, please call to confirm what is required for testing.

Documentation Required for Testing

Please have documentation that shows your name (may be current or expired). Name verification is required to identify individuals who have been tested multiple times. Examples of verification documents:

  • Photo ID
  • Passport (any country)
  • School ID
  • Library card
  • Consular ID card
  • A bill with your name on it
  • RTD pass with your name on it
  • Colorado Quest Card (EBT card) 

If you need a sign language interpreter or CART Services, contact with at least a three (3) business day notice. For other public accommodation requests/concerns related to a disability, please contact

Contact Tracing

What is Contact Tracing?

Contact tracing, coupled with rigorous testing, can counteract a potential second wave and prevent cases from spiking again. Contact tracing is part of the overall function of case management in public health.

There are three main components to case management:

  • Interviews: Trained staff interview people who have been diagnosed with COVID-19 to determine who they may have been in close contact with during the time they were considered to have been infectious.
  • Contact tracing: Staff then warns these individuals, or contacts, of their potential exposure as quickly and sensitively as possible. In order to protect patient privacy, contacts are only informed that they may have been exposed to an individual with the infection. They are not told the identity of the person who may have exposed them. They are offered resources and support.
  • Contain: People who have had contact with a COVID-19 positive patient are provided with education, information, and support to understand their risk, what they should do to separate themselves from others, how to monitor themselves for illness, and the possibility that they could spread the infection to others even if they themselves do not feel ill. If a contact becomes symptomatic, the local public health department can be contacted to assist them in getting tested. If the contact tests positive for COVID-19, their recent contacts will be traced and informed, too.

It is very important that residents help the health workers by answering the phone. Health workers will not ask any private questions about finances or social security numbers. 

The process continues until everyone who has been exposed is isolated from others to reduce virus transmission. Contact tracing, coupled with rigorous testing, can counteract a potential second wave and prevent cases from spiking again.

Denver Department of Public Health & Environment is not currently hiring or soliciting volunteers for Contact Tracing, as we are managing with internal and partner resources. If DDPHE does begin seeking volunteers or hiring staff for Contact Tracing, we will post a link on this page. Please check back in the future, and we appreciate all of the offers of support we have received thus far!

Is Denver working with other cities?

Since COVID-19 does not stop at jurisdictional boundaries, Denver will work with other regional local public health agencies to continue coordinating case investigations and to improve contact tracing. The partnership will help to ensure contact tracing will be complete and thorough.



The City and County of Denver has enacted the "Adoption of Level Red-Severe Risk" Public Health Order. Effective at 5 p.m. Friday, November 20, the State is requiring Denver to adopt greater restrictions pursuant to the amended Colorado Public Health Order

All public and private gatherings of people who are not members of a single household are prohibited except for limited purposes.

Denver’s tougher face-covering mandate, issued on October 16, 2020, is also still in effect until further notice.
