About this data Sources: State and local health agencies (cases, deaths); U.S. Department of Health and Human Services (tests, hospitalizations). The seven-day average is the average of a day and the previous six days of data. Currently hospitalized is the most recent number of patients with Covid-19 reported by hospitals in the state for the four days prior. 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. Tests represent the number of individual P.C.R. viral test specimens tested by laboratories and state health departments and reported to the federal government.

Outbreak clusters

Since March 2020, The Times has paid special attention to cases in the types of places with some of the worst outbreaks, like nursing homes, food processing plants and correctional facilities.

Cases Connected To Location Cases
University of Colorado Boulder Boulder, Colo. 3,676
Colorado State University Fort Collins, Colo. 3,103
University of Denver Denver, Colo. 1,280
Colorado Mesa University Grand Junction, Colo. 1,234
Colorado School of Mines Golden, Colo. 746
University of Northern Colorado Greeley, Colo. 682
University of Colorado Colorado Springs Colorado Springs, Colo. 344

About this data Information on cases linked to these places comes from official releases by governments, companies and institutions directly. The Times is publishing lists of groupings of 50 or more cases related to a specific site, workplace or event.

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. Colorado typically releases new data each day. Weekend counts may be lower because fewer sources report to the state. The state reports cases and deaths based on a person’s permanent or usual residence.

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

  • 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.
