High seroprevalence for SARS-CoV-2 among household members of essential workers detected using a dried blood spot assay

14 Aug 2020

Abstract excerpt

OBJECTIVE: Serological testing is needed to investigate the extent of transmission of SARS-CoV-2 from front-line essential workers to their household members. However, the requirement for serum/plasma limits serological testing to clinical settings where it is feasible to collect and process venous blood. To address this problem we developed a serological test for SARS-CoV-2 IgG antibodies that requires only a...
