Evaluation of IgG Neutralizing Antibodies to SARS-CoV-2 Among Healthcare Workers Who Frequently Encountered COVID-19 Patients in Our Hospital

Since the severe acute respiratory syndrome Coronavirus-2 (SARS-CoV-2) first emerged in Wuhan, China, on 12 December 2019, it has spread rapidly across the world and developed into a pandemic. The pandemic has affected over 100 countries and regions, with over 132 million confirmed cases of COVID-19. The rapid spread of SARS-CoV-2 has caused considerable harm to public health and the economy. Alongside other laboratory tests and clinical findings of the COVID-19 infection, serological testing may be beneficial for epidemiological monitoring and outbreak control. The determination of antibodies enables confirmation of the SARS-CoV-2 infection in asymptomatic patients in addition to those with typical symptoms. In this study, we aimed to determine the SARS-CoV-2 seroprevalence and the IgG antibody levels among healthcare workers who frequently encountered COVID-19 patients in our hospital.
