Antibody Responses 8 Months after Asymptomatic or Mild SARS-CoV-2 Infection

Abstract

Waning humoral immunity in coronavirus disease patients has raised concern over usefulness of serologic testing. We investigated antibody responses of 58 persons 8 months after asymptomatic or mildly symptomatic infection with severe acute respiratory syndrome coronavirus 2. For 3 of 4 immunoassays used, seropositivity rates were high (69.0%-91.4%).

Keywords: 2019 novel coronavirus disease; COVID-19; ECLIA; ELISA; SARS-CoV-2; antibody; coronavirus disease; respiratory infections; severe acute respiratory syndrome coronavirus 2; viruses; zoonoses.
