REPACK Download Remnant Records V2.1.1

Here we present a blueprint and the early results of the ongoing SCALE-IT study (Serosurveillance for Continuous, ActionabLe Epidemiologic Intelligence of Transmission), leveraging residual sera samples from two large hospital systems in San Francisco, California to quantify the prevalence of SARS-CoV-2 antibodies. Importantly, these remnant samples are linked to electronic health records (EHRs) enabling careful algorithmic selection based on demographic and clinical variables, improving their representativeness to the general population. We tested over 5000 samples collected from late March to June 2020 from San Francisco residents, and calculated raw and adjusted seroprevalence estimates over space, time, and socio-demographic indicators. These data provide estimates of the overall seroprevalence in San Francisco during the initial phase of the local SARS-CoV-2 outbreak and highlight spatial and demographic heterogeneities in transmission across the city.
