Abstract
We compared levels of severe acute respiratory syndrome coronavirus 2 neutralizing antibodies in recovery plasma from 7 completely asymptomatic coronavirus disease patients with those in symptomatic patients in South Korea. We found that serologic diagnostic testing was positive for 71% (5/7) of completely asymptomatic patients, but neutralizing antibody response occurred in all 7 patients.
Keywords: 2019 novel coronavirus disease; COVID-19; SARS; SARS-CoV-2; asymptomatic; coronavirus; coronavirus disease; neutralizing antibody; respiratory infections; severe acute respiratory syndrome coronavirus 2; viruses; zoonoses.
