  • Antibodies against SARS-CoV-2 were found in 80% of a community sample of 30 individuals who shared a household with a confirmed COVID-19 case but who had not had a prior SARS-CoV-2 diagnosis. McDade et al. tested for anti-SARS-CoV-2 antibodies using a dried blood spot assay from self-collected samples.
