COVID-19 in Denver


COVID-19 Case Summary

Beginning Nov. 22, information on these dashboards is updated every weekday by 6:30 p.m.  

COVID-19 case reporting represents laboratory-confirmed and probable cases of COVID-19 among residents living in Denver County, Colorado. The Denver Department of Public Health & Environment investigates all lab-confirmed cases of COVID-19 among Denver residents through interviews and medical record reviews. These data may not reflect information for cases currently under investigation.  

The numbers and information on this page may differ from the Colorado Department of Public Health and Environment due to differences in timing of reporting and case classification. There are also delays in data entry that limit our ability to know whether recently reported cases have been hospitalized.  

Additional data on COVID-19 vaccine doses administered to Denver County residents is being tracked by the Public Health Institute at Denver Health.  

COVID-19’s disproportionate impact on neighborhoods and communities of color is critical. Public health agencies in Denver are working hard to ensure free testing and access to care and resources are available for communities that are most adversely impacted by the COVID-19 epidemic in Denver.  

The dashboards reflect data from confirmed and probable COVID-19 cases among Denver County residents.

Epi Curves 

Total Cases

The following graphs show the number of confirmed and probable COVID-19 cases among Denver residents over time. Counts may differ from other data sources depending on lags in reporting or timing of updates.



The following graphs show the number of deaths among COVID-19 cases in Denver. A death is counted when a COVID-19 patient dies within 30 days of their symptom onset or test date and is a resident of Denver County. Death data is derived from the Colorado Department of Public Health & Environment's Colorado Electronic Disease Reporting System and is based on death certificate data. Counts may differ from other data sources depending on lags in reporting or timing of updates. 

One Week Incidence Rate

Denver Hospital Census

Data shows the total number of COVID-19 patients in Denver hospitals on a given day. This includes all patients regardless of what county they live in (not just Denver residents).


Information about how the overall demographics of the COVID-19 epidemic in Denver have shifted, which aligns with a shift in exposures leading to infection. When COVID-19 cases were first reported in Denver in early March, a time when stay-at-home orders had not yet been enacted and there was still widespread travel, most cases were acquired through travel and/or exposure to a known case in specific settings (conference, health care workers). Over time as COVID-19 began spreading widely in the community, these exposures became a less likely source of exposure and more cases appeared among families and general contact with the community.


Over time, COVID-19 infection rates have varied in Denver, we have seen a notable increase over time in the proportion of cases who identify as Hispanic or Latino. Examining COVID-19’s impact on communities of color is critical and analyzing data in this way can help us to advocate for allocation of resources and outreach towards populations and communities with elevated needs.   

Race/Ethnicity Incidence


Case Percent by Race/Ethnicity


Cumulative Race/Ethnicity


We have seen shifts over time in the age groups being most severely impacted by COVID-19 that align with shifts in exposures in the community. At the beginning of the pandemic we saw increased rates of infection among older populations, notably people in their 70s and 80s, especially as long-term care facilities reported outbreaks. As COVID-19 began spreading further in the community, we began to see increased rates among people aged 20-40 years, which includes a large portion of our essential workforce. We continue to monitor trends in age demographics to better understand community spread.

Outbreaks in Denver

Denver Department of Public Health & Environment (DDPHE) is collaborating with local businesses, organizations and community partners to investigate and control COVID-19 outbreaks. Outbreaks are clusters of COVID-19 cases that appear related to a single workplace, business, school, facility or event. Learning from and controlling outbreaks helps us slow the spread of COVID-19. 

This dashboard reflects information about outbreaks and the number of cases involved in COVID-19 outbreaks in Denver since the start of the pandemic. This information is updated weekly on Wednesday afternoon and mirrors information available in Colorado Department of Public Health & Environment’s (CDPHE) public COVID-19 outbreak data page. Numbers may differ slightly from CDPHE based on when the dashboard is updated. 


Case and Outbreak Definitions

Frequently Asked Questions

When would COVID-19 cases be classified as an outbreak?

In most settings, a confirmed outbreak is defined as five or more confirmed or probable cases of COVID-19, of which at least one case has had a positive molecular amplification test or antigen test performed by a CLIA-certified provider, in a facility or (non-household) group with onset in a 14 day period.

In special settings, such as residential care facilities or correctional institutions, a confirmed outbreak is defined as:

  • Two or more confirmed COVID-19 cases in residents/inmates/detainees/etc. with onset in a 14-day period or, 
  • One confirmed and two or more probable COVID-19 cases in residents/inmates/detainees/etc. with onset in a 14-day period. 

When is a COVID-19 outbreak considered over?

In most settings, a COVID-19 outbreak is considered resolved when 28 days have passed since the symptom onset date (or test collection date, if asymptomatic) of the last newly identified COVID-19 case.

COVID-19 Outbreak Resources and Guidance for Facilities and Businesses

Report a suspected outbreak of COVID-19 in a Denver workplace or organization

Once an outbreak is reported, a DDPHE representative will be in contact to review next steps. DDPHE is unable to respond to incomplete reports, so please complete the information in the survey as completely and accurately as possible. Long-term care facilities (nursing homes, assisted living facilities, etc.) should send an email directly to to report any cases or outbreaks. Visit the Centers for Disease Control and Prevention’s Workplace Guidance for in-depth information and resources related to managing a COVID-19 outbreak.

Please note an outbreak determination does not necessarily mean all cases acquired their illness in that specific workplace/facility. It is possible that a case may have been exposed elsewhere (we can rarely prove where any individual was exposed with a person-to-person pathogen). But when a case worked/spent time in a workplace/facility with a known outbreak, we attribute their illness to that outbreak even if there is no definitive proof that the case acquired the illness there. This conservative approach is consistent across all outbreak types.  

Report a COVID-19 Outbreak

After a Suspected Outbreak is Reported

Once a confirmed or suspected outbreak is reported, a representative from DDPHE will be assigned as the main point of contact to provide resources and collect information. If the facility/workplace is located in another county, DDPHE will forward the information provided to that county for follow-up.  

While you are waiting for public health follow-up, please see the recommended steps below: 

  1. Using the appropriate line list template, please begin recording information about your staff, guests or residents who have developed COVID-19-like symptoms or who have tested positive for COVID-19.
  2. Ensure any staff, guests or residents who are currently ill or tested positive for COVID-19 are isolating according to public health isolation guidelines.
  3. Ensure any staff, guests or residents who were in close contact with a confirmed or probable COVID-19 case are quarantining according to public health quarantine guidelines.
  4. Reference CDC’s Workplace Guidance for initial recommendations regarding cleaning and disinfection, testing and maintaining a healthy work environment.
  5. If you have employees who need to take time off work due to COVID-19 illness or exposure, please reference the Families First Coronavirus Response Act page for information for your business about the law regarding this time off.
  6. If you have questions or need assistance with COVID-19 testing, please visit CDPHE’s testing page for more information.
  7. If you have questions or need assistance with COVID-19 vaccination, please visit DDPHE’s vaccination page for more information.
  8. For general questions about COVID-19, you can call CO HELP at 1-877-462-2911 or 303-389-1687.
