COVID-19 Outbreak Locations

These data represent outbreaks of cases of COVID-19 in all setting types, except Long-Term Care/Skilled Care Facilities, Assisted Living Facilities, and Developmentally Disabled Facilities. Long Term Care Facility Outbreaks can be found Here.

Local health departments investigate outbreaks by identifying clusters from individual case investigations. This information is based on reported locations visited during their 14-day exposure period.

An outbreak is defined as five or more cases that are linked to a common location during a 14-day period. These linked cases also must be from different households and not already connected from other sources. Additionally, outbreaks do not include secondary cases from those originally linked to the outbreak (e.g., person who becomes infected from their workplace and then passes the infection onto a household member). 

Table 1 represents newer outbreaks where the first identified case in the outbreak had an onset date within the past 30 days. Table 2 represents all outbreaks since the Phase 4 reopening where cases have an onset date on or after July 1, 2020.

Many factors may result in underreporting of outbreaks. Cases may go undetected because those infected are not tested and some are asymptomatic. Additionally, cases may not respond to phone calls from contact tracers or may not disclose all the locations visited..
