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.
Please note that during the dramatic increase in the number of Santa Clara County residents contracting COVID-19 between November 2020 and January 2021, the County of Santa Clara Public Health Department’s Case Investigation and Contact Tracing (CICT) Team temporarily shifted its contact tracing procedures to prioritize the notifying cases of their need to isolate, offering support for isolation, and gathering critical information to guide policy decisions. Positive cases were asked to provide quarantine and testing information to contacts in their own household, while our CICT Team attempted to contact only non-household contacts. Therefore, the data highlighted in red in the graphics below reflect a substantial change in activities and cannot be compared to current or previous efforts.
