COVID-19 Case Investigation and Contact Tracing Dashboard

The data in this dashboard provide information about case investigation and contact tracing efforts by the Public Health Department.​ Case investigation and contact tracing (CICT) are core interventions used by local and state health departments to control the spread of many communicable diseases, including COVID-19. The primary goals of CICT are to ensure that people who test positive for COVID-19 or have been exposed are able to safely stay home and away from others and not expose more people. The program also works to make sure people who need health care, housing and food assistance, or other supports to safely stay home while they are infectious or exposed to COVID-19 are able to receive them.  
 
CICT is part of the process of supporting patients and warning contacts of exposure in order to stop chains of transmission. Tracking key metrics such as those below can help the Public Health Department improve the effectiveness of this important tool.

Data Notes: Contacts are individuals that had a close contact to someone with COVID-19. A close contact is defined as someone who was within 6 feet or less for 15 minutes or longer of a person diagnosed with COVID-19 during the period that person was infectious. Contacts may have multiple entries if they have more than one exposure. The percent of cases interviewed is the percent of COVID-19 cases reported to the Public Health Department that completed an interview with a CICT staff, including discussion of isolation guidelines and elicitation of contacts. The percent of contacts interviewed is the percent of contacts that completed an interview with a CICT staff, including discussion of quarantine guidelines. The percent of cases with any contacts elicited is the percent of COVID-19 cases reported to the Public Health Department that provided information for at least one contact. The weekly average number of contacts elicited is the 7-day average number of close contacts for whom cases provided information to the Public Health Department, among all cases that provided at least one contact during the interview. The percent of cases and contacts requesting resources is the percent of all cases and contacts reported to the Public Health Department that requested support in order to safely isolate or quarantine. Unable to reach/other includes individuals that do not have contact information, were reported to the Public Health Department more than 28 days after the initial onset or exposure, or were unable to be reached despite six or more attempts. For all cases and contacts with contact information reported within 28 days of onset/exposure, the CICT team attempts to contact the person within 24 hours of receiving the report, and usually within 2-4 hours.
