Outbreak data

Data include all CONFIRMED outbreaks of COVID-19 reported in Colorado.

Data on case counts is provided by each facility with an outbreak. Data is requested each week.

How do you know a case wasn't exposed elsewhere in the community and not the outbreak facility?
It is possible that a person may have been exposed elsewhere (and we can rarely prove where any individual was exposed with a person-to-person pathogen), but when a person worked/lived/spent time in a facility with a known outbreak, we attribute their illness to the outbreak even if there is no definitive determination that the case acquired the illness at the facility. This approach is consistent across all outbreak types.

Investigation status

Outbreak is ongoing if investigation status = ACTIVE. Outbreak is over if investigation status = RESOLVED.

  • In health care settings, including long-term care facilities, assisted living facilities, independent living facilities/senior communities that offer health care, inpatient rehab facilities, and long-term acute care hospitals.
  • In correctional settings, including state prisons, county and city jails, community corrections, detention settings, work release facilities.
  • In other settings, including factories, workplaces with crowded work conditions, camps, schools, child care centers, and independent living facilities/senior communities that do not offer health care. 

  • Confirmed COVID-19 Outbreak: Two or more Confirmed cases of COVID-19 in a facility or (non-household) group with onset in a 14 day period.
  • Confirmed COVID-19 Outbreak in a Healthcare Facility: Two or more Confirmed COVID-19 cases in residents with onset in a 14 day period.
  • Confirmed COVID-19 Outbreak in a Correctional Setting: Two or more Confirmed COVID-19 cases in residents/inmates/detainees/etc with onset in a 14 day period.

In general, the definition is the same: Two or more confirmed cases that began in a 14-day period. The definition for non-hospital health care facilities is more specific because outbreaks of any kind in these facilities tend to spread very rapidly and because the residents are at higher risk of severe illness and death. A more lenient definition means interventions to control the outbreak can occur more quickly

We use illness in residents to define outbreaks in nursing homes and correctional settings because it's a better indicator of spread of infection in the facility. Once we’ve identified there is an outbreak, staff are included in the case counts. 

 

A COVID-19 outbreak is over when 28 days have passed with no new illness.

  1. A facility suspects an outbreak based on defined criteria and notifies local or state public health.
  2. Public health assesses the facility’s current practices and provides the facility with l assistance and support regarding infection prevention, personal protective equipment, testing strategies, and staffing recommendations.
  3. The facility implements appropriate mitigation measures, focusing on controlling the outbreak.
  4. The facility submits a final outbreak report to CDPHE once the outbreak is considered over.

CDPHE 's nursing home rules require that all nursing homes have a policy regarding notification to a resident's representative. Notifications must be made for incidents, accidents, and changes of status, which could include illness. These rules do not specify notification of a family member when a resident is ill, but each facility's policy should address when and for what reasons notifications to resident representatives occur. CDPHE recommends communication with residents and families in the COVID-19 Preparation and Rapid Response guidance. To be as transparent as possible during the pandemic, CDPHE is releasing facility outbreak information before investigations are complete. Anyone can go to covid19.colorado.gov for the latest weekly update.

Outbreaks should be reported to the local public health agency in the county where the  suspected outbreak is located.

The state updates information about outbreaks weekly on Wednesdays by about 4 p.m.

Although public health is typically notified immediately about a possible outbreak, specific information, like the number of cases, is not available until epidemiologists can investigate the facility to gather more details. There are many complexities in this type of investigation that require further information gathering and analysis to provide an accurate account of the outbreak. Some of these factors include:

  • Some sites, such as hospice care facilities, have populations that already exhibit a variety of illnesses and who experience a higher mortality rate than the general population. It is not necessarily obvious whether someone is ill or died due to COVID-19 or due to their existing medical conditions.
  • Some residents of the facilities have do-not-resuscitate orders in place. This can mean that they will not receive advanced medical care and testing that might determine the cause of their death. 
  • Laboratory-confirmed positive cases are only reported as long as facilities are testing. Once there is confirmed transmission in a facility, it isn’t necessary to continue testing all new cases since they meet the probable case definition.
  • All facilities must report probable cases, as well as confirmed cases, to public health. Probable cases change frequently as epidemiologists investigate further and facilities require additional testing to rule out other respiratory illnesses. Facilities must report a full accounting of probable cases after an outbreak is over.

Because facilities are focused on disease control measures during an outbreak, the number of cases reported for each facility may be incomplete. A full accounting of all cases in an outbreak is made available when a facility submits their final report at the end of the outbreak.
