Tracking SARS-CoV-2 seroprevalence in frontline healthcare workers at the beginning of COVID-19 pandemic and reliability of serological laboratory interpretation: a prospective cohort study
An extremely low prevalence of SARS-CoV-2 infection among HCWs in Thailand at the pandemic's outset, likely due to effective transmission control. Pre-existing antibodies against other human coronaviruses could lead to false positive serological testing for SARS-CoV-2.
