Seattle Coronavirus Assessment Network

Working Alongside Community Organizations And Connecting Experts In Medicine, Science, And Public Health To Enable Researchers And Health Officials Track The Coronavirus

The Greater Seattle Coronavirus Assessment Network (SCAN) ended active recruitment of new participants on July 31, 2022. The SCAN study provided crucial information about the spread of COVID-19 in the Seattle area. It became one of the first community surveillance programs for COVID-19 in the United States, meeting a critical gap in testing and providing crucial data on how the virus was spreading and changing. Learn more about the history and accomplishments of SCAN.

The Greater Seattle Coronavirus Assessment Network, (SCAN) emerged in March of 2020 to help researchers and public health leaders track the spread of the coronavirus. It supports efforts to control coronavirus by providing public health leaders in the Greater Seattle region and researchers worldwide with information about how the virus spreads. SCAN connects experts in medicine, science, and public health from across Seattle and beyond to help protect our community.

It provides free at-home testing for COVID-19. The findings are helping BBI’s research partners, including Public Health – Seattle & King County and Tacoma-Pierce County Health Department, keep people informed and make the best possible, data-driven decisions. Whether you are healthy or sick, you or a family member may be able to support SCAN’s research by collecting your own nasal swab at home and returning it to BBI’s laboratories. One of the research project’s main goals is to use testing resources to understand how children, high-risk, and underrepresented communities are affected by the virus.
