COVID-19 Case Investigation and Contact Tracing Dashboard

Published by data.kingcounty.gov | King County, Washington | Metadata Last Checked: July 29, 2025 | Last Modified: 2021-09-22
Case investigation and contact tracing are essential strategies for limiting the spread of COVID-19, along with face coverings, social distancing, handwashing and testing. Public Health's Case Investigation and Contact Tracing Team calls King County residents who have recently tested positive for COVID-19 ("cases"). And they call people who were exposed to COVID-19 ("contacts"). The phone calls include an explanation of isolation and quarantine guidelines, how to get testing and support services, and collecting information that helps Public Health's infection control programs.
