About this data Sources: State and local health agencies (cases, deaths); U.S. Department of Health and Human Services (test positivity, hospitalizations, I.C.U. patients). Test positivity, hospitalizations, I.C.U.s and deaths show seven-day averages. Test positivity is based only on P.C.R. test results reported to the federal government. Test positivity, hospitalization and I.C.U. data may not yet be available for yesterday. Figures shown are the most recent data available.

Latest trends

  • An average of 329 cases per day were reported in Colorado in the last week. Cases have decreased by 23 percent from the average two weeks ago. Deaths have decreased by 25 percent.
  • Since the beginning of the pandemic, a total of 1,771,010 cases have been reported. At least 1 in 404 residents have died from the coronavirus, a total of 14,245 deaths.
  • January 2022 was the month with the highest average cases, while December 2020 was the month with the highest average deaths in Colorado.

How to read Covid data now

Higher test positivity rates are a sign that many infections are not reported — even if they are tested for at home. This results in a more severe undercount of cases. The number of hospitalized patients with Covid is a more reliable measure because testing is more consistent in hospitals. Read more about the data.

Daily new hospital admissions by age in Colorado

This chart shows for each age group the number of people per 100,000 that were newly admitted to a hospital with Covid-19 each day, according to data from the U.S. Department of Health and Human Services. Dips and spikes could be due to inconsistent reporting by hospitals.

About this data Sources: State and local health agencies (cases, deaths); U.S. Department of Health and Human Services (test positivty, hospitalizations, I.C.U. patients). The seven-day average is the average of the most recent seven days of data. Cases and deaths data are assigned to dates based on when figures are publicly reported. Figures for Covid patients in hospitals and I.C.U.s are the most recent number of patients with Covid-19 who are hospitalized or in an intensive care unit on that day. Dips and spikes could be due to inconsistent reporting by hospitals. Hospitalization numbers early in the pandemic are undercounts due to incomplete reporting by hospitals to the federal government. Test positivity is based on P.C.R. viral test specimens tested by laboratories and state health departments and reported to the federal government. Hospitalizations and test positivity are reported based on dates assigned by the U.S. Department of Health and Human Services and are subject to historical revisions.

This calendar shows data through 2022 and will no longer be updated in 2023. The Times will continue to report the data for other displays on this page.

About the data

In data for Colorado, The Times primarily relies on reports from the state, as well as health districts or county governments that often report ahead of the state. The state does not update its data on weekends. Prior to July 2021, it released new data daily. The state reports cases and deaths based on a person’s permanent or usual residence.

The Times has identified reporting anomalies or methodology changes in the data.

More about reporting anomalies or changes
  • Nov. 16, 2022: The Times began using state data for the Tri-County region after local officials stopped reporting data regularly, resulting in a one-time decrease in cases and deaths.
  • Nov. 11, 2022: The Times began including death certificate data reconciled by the C.D.C., resulting in a one-day increase in total deaths.
  • Sept. 15, 2022: Colorado added many older cases.
  • Sept. 1, 2022: Colorado added many older cases.
  • Aug. 4, 2022: Colorado added many older cases.
  • July 21, 2022: Colorado added many older cases.
  • July 7, 2022: Colorado added many older cases.
  • June 23, 2022: Colorado added many older cases.
  • June 9, 2022: Colorado added many older cases.
  • May 26, 2022: Colorado added many older cases.
  • May 12, 2022: Colorado added many older cases.
  • May 3, 2022 to May 4, 2022: Colorado added many deaths.
  • April 13, 2021: The local health department for Adams, Arapahoe and Douglas Counties added many deaths.
  • March 1, 2021: Colorado added about 800 cases from recent months representing people who were infected twice.
  • April 25, 2020: Colorado revised downward the number of deaths after removing "about 29 duplicates" from the number of probable deaths included in the total.
  • April 24, 2020: Colorado added a number of cases from a testing backlog.

The tallies on this page include probable and confirmed cases and deaths.

Confirmed cases and deaths, which are widely considered to be an undercount of the true toll, are counts of individuals whose coronavirus infections were confirmed by a molecular laboratory test. Probable cases and deaths count individuals who meet criteria for other types of testing, symptoms and exposure, as developed by national and local governments.

Governments often revise data or report a single-day large increase in cases or deaths from unspecified days without historical revisions, which can cause an irregular pattern in the daily reported figures. The Times is excluding these anomalies from seven-day averages when possible. For agencies that do not report data every day, variation in the schedule on which cases or deaths are reported, such as around holidays, can also cause an irregular pattern in averages. The Times uses an adjustment method to vary the number of days included in an average to remove these irregularities.
