Boulder County COVID-19 Illness & Recovery Summary

The information below is a summary of information about Boulder County residents who have tested positive for COVID-19 or are likely positive (Probable*) for COVID-19. The information is compiled and analyzed by Boulder County Public Health from disease investigations conducted with those who have tested positive for COVID-19 in the county combined with reports from the Colorado Department of Public Health and Environment, local hospitals, and the Boulder County Coroner.

Information will be updated daily by 4 p.m. Please note that details provided on the Colorado Department of Public Health and Environment website may not match this information due to delays in reporting. This information is subject to change at any time as disease investigations are ongoing.

Updated: June 6 at 3:00 p.m. (Beginning May 25, graphs are updated on Tuesdays and Thursdays.)

Illness and Recovery

The information below only represents individuals who have tested positive or are considered probable for COVID-19. There is confirmed community-wide spread in the community so it is likely that many more Boulder County residents have or have had the illness.

Boulder County Public Health is notified of Boulder County residents who test positive for COVID-19. Unfortunately, we are not notified, and do not have access to the total number of Boulder County residents who are tested for the disease (e.g. negative COVID-19 test results).

Status Number of Individuals in Boulder County
Tested positive or considered Probable* (likely positive) for COVID-19, to date 999
Hospitalized due to COVID-19, to date 166
Recovered 479
Disease investigation currently in progress 165
Deceased due to COVID-19** 63


The following information includes data about COVID-19 PCR (diagnostic) testing among Boulder County residents. Data presented includes 3 days prior to receiving the test result due to the approximately 3 day average lag between the time a test is conducted and when the results are reported to the Colorado Department of Public Health and Environment.

Total PCR (diagnostic) COVID-19 Tests Among Boulder County Residents, to Date Percent of Positive Tests (PCR only)
9,162 9.3%

Transmission Source

The graph below represents the source of transmission among residents who tested positive or are considered probable for COVID-19 and who knew the source of their exposure. Weeks with an asterisk (*) have incomplete data due to testing/reporting delays.

Community: transmission that occurred within Boulder County or another Colorado county where the ill person attends work or school. Limited person-to-person: primarily transmission within the household. Travel: transmission from travel outside of Boulder County, including to other Colorado counties, other states, and other countries.

*Some data are missing due to ongoing disease investigations. Includes confirmed and probable.


This graph presents case counts by day rather than growth rates in total cases over time to increase interpretation and actionability of the data.

Town/City of Residence

There is confirmed community-wide spread of COVID-19 in Boulder County, so regardless of where we live, we must all take the recommended precautions to stop the spread of the virus. Please note: The previous graphs used a street address to determine the municipality. The current method uses actual boundaries for cities as well as for unincorporated Boulder County. The new method is more accurate, though the actual case count may differ slightly from the previous graphs.

To protect patient privacy, municipalities with fewer than 3 people with confirmed or probable COVID-19 are not included, in alignment with the Colorado Department of Public Health and Environment.

Note: Due to rate instability, rates are not calculated for municipalities with fewer than 5 people positive or probable for COVID-19.


At the heart of disparities is systematic racism which research illustrates creates institutional barriers to things like preventive medical care, healthy food, safe and stable housing, quality education, reliable transportation, and clean air impact health outcomes. Hispanic/Latinx individuals in Colorado are also more likely to have some chronic diseases known to increase the potential severity of COVID-19, namely, overweight or obesity and diabetes. These chronic conditions are closely linked to the institutional barriers mentioned above.

Long-Term Care Facilities in Boulder County

Older individuals, those with underlying health conditions, and anyone who lives in a congregate setting, such as a long-term care facility is more at risk for contracting COVID-19, and at greater risk for severe illness and death from the virus. For detailed information about outbreaks in Boulder County long-term care facilities, visit the CDPHE outbreak data webpage.

Hospital Status

About this information

Currently Hospitalized

We do not have access to information about who is no longer hospitalized due to COVID-19. Gathering this information would require our staff to conduct a medical record review for patients as well as contact patients/family. Unfortunately, we currently don’t have the resources.


Boulder County Public Health reports deaths due to COVID-19 of Boulder County residents only while the Boulder County Coroner reports all deaths that occur within the county, regardless of county of residence.

Disease Investigations

As with all reportable diseases, Boulder County Public Health staff contact each Boulder County resident who tests positive for COVID-19 to identify any person who may have come in close contact with the ill person. Each close contact who is identified as at risk of contracting the disease is then contacted and provided guidance for next steps, including isolation, quarantine, and/or testing, if needed.

We have requested additional support to be able to continue these contact tracing and monitoring practices as more of our residents become ill from COVID-19. These practices are vital to identifying the presence of disease and the response actions needed to protect residents.


It may be deemed that a person is “Probable” (e.g. probably positive for COVID-19) if they came in close contact with a person who has tested positive for COVID-19 and was determined to be high risk during the disease investigation, AND they became symptomatic in the two weeks after contact with the ill person or the two weeks before, while they were infectious.


An individual is considered “Recovered” if at least 7 days has passed since symptom onset (10 days after discharge for individuals who have been hospitalized) AND they have been fever-free for at least 3 days AND moving towards resolution of symptoms. “Recovered” may also include individuals who we were unable to follow-up with, but for whom more than 14 days have passed since symptom onset.
