COVID-19: Facility-Wide Public Health Investigations

On August 11, 2022, Centers for Disease Control and Prevention (CDC) updated the COVID-19 guidance for community, school, and early childhood education settings. The Wisconsin Department of Health Services (DHS) supports these updates and is currently working to update its website and materials to reflect these changes.

Information on COVID-19 reported by nursing homes to the Center for Disease Control and Prevention (CDC's) National Healthcare Safety Network (NHSN) COVID-19 Long Term Care Facility Module is available on the U.S. Centers for Medicare and Medicaid Services (CMS) data portal.

Data shown below are subject to change. As individual cases are investigated by public health, there may be corrections to the status and details of cases. Below, there is also a list of nursing homes with active COVID-19 facility-wide public health investigations in Wisconsin by county.

Understanding our data: What does this chart mean?

This dashboard shows the number of active and total investigations by setting, including a list of nursing homes with active public health investigations. This data helps us identify which settings are experiencing a larger proportion of investigations due to COVID-19 cases.

*When nursing homes detect COVID-19, it is a sign that they are following proper notification procedures. It also indicates that the nursing home is working with public health experts to test and protect their residents and employees with appropriate isolation and infection control practices. Proactive testing helps address outbreaks early on when they are easier to manage.

Please note: 

  • February 16, 2022: This visualization was updated to include both confirmed and probable cases. Data prior to February 1, 2022 includes only confirmed cases.

About our data: How do we measure this?

A single confirmed or probable case in the following setting initiates a facility-wide public health investigation:

  • Long-term care facilities include skilled nursing facilities (nursing homes) and assisted living facilities (community-based residential facilities and residential care apartment complexes).

Two or more confirmed or probable cases in the following settings initiate a facility-wide public health investigation:

  • Group housing facilities include correctional facilities, homeless shelters, dormitories, and group homes.
  • Health care facilities include hospitals, clinics, dialysis centers, hospice, and in-home care.
  • Workplace (non-health care) settings include manufacturing and production facilities, distribution facilities, offices, and other indoor workplaces.
  • Educational facilities include schools, colleges, universities, and child day care centers.
  • Other settings include adult day care centers, restaurants, event spaces, and religious settings.

A case investigation and contact tracing is conducted with all people reported with COVID-19, regardless of setting.

Facility-wide and outbreak investigations are considered closed when two maximum incubation periods have passed since the last possible exposure to a COVID-19 case in the facility without any new cases. For COVID-19, two maximum incubation periods are 28 days (maximum incubation period is 14 days).

We plan to update our data each Wednesday by 2 p.m.
