Symptoms of COVID-19 Infection and Magnitude of Antibody Response in a Large Community-Based Study [open pdf - 0B]
From the Abstract: "The majority of COVID-19 [coronavirus disease 2019] cases are asymptomatic, or minimally symptomatic with management in the home. Little is known about the frequency of specific symptoms in the general population, and how symptoms predict the magnitude of antibody response to SARS-CoV-2 [severe acute respiratory syndrome coronavirus 2] infection. [...] The researchers quantified IgG [Immunoglobulin G] antibodies against the SARS-CoV-2 receptor binding domain (RBD) in home-collected dried blood spot samples from 3,365 adults participating in a community-based seroprevalence study in the city of Chicago, USA, collected between June 24 and November 11, 2020."
