Abstract
Despite an impressive number of clinical trials and evidence-based data [1], no antiviral treatment is recommended in subjects with coronavirus disease 2019 (COVID-19) and no or mild symptoms [2]. Neutralizing [...]
We describe the time course of neutralizing antibody (NtAb) titer in a cohort of health care workers with mild or asymptomatic severe acute respiratory syndrome coronavirus (SARS-CoV-2) infection. NtAb levels decreased over time; however, serum neutralizing activity remained detectable after a median of 7 months from SARS-CoV-2 diagnosis in the majority of cases. Keywords. follow-up; health care workers; mild or asymptomatic infection; neutralizing antibody titer; SARS-CoV-2.
