San Diego County was one of seven California counties that participated in CalScope. CalScope was a study conducted by the California Department of Public Health (CDPH) to learn how many Californians had antibodies to the virus that causes COVID-19. CalScope provided the CDPH with the information they needed to make crucial decisions to help protect Californians from COVID-19.

The CalScope serosurvey took place in three separate waves during 2021-2022. Wave 1 was conducted from May-June 2021. Wave 2 was conducted from October 2021-February 2022, and Wave 3 was conducted from April-August 2022. As of July 29, 2022, participant enrollment in CalScope has ended.

To learn more about the results and findings of CalScope, visit the CDPH website to view their reports and publications. Additionally, a publication using CalScope data was published on January 16, 2023—Evaluating the association between in-person work and the risk of SARS-CoV-2 infections through June 2021—American Journal of Industrial Medicine, January 2023.
