Anti-SARS-CoV-2 IgG seroprevalence among non-vaccinated healthcare workers: a study from rural North India

Abstract

Coronavirus disease 2019 (COVID-19) is novel viral disease caused by SARS-CoV-2. In December 2019, it was first reported in Wuhan, China. Around the world, the disease has spread across 210 countries with a total of more than two million confirmed cases. In India, the first case was detected on 30 January 2020 in Kerala in a student who returned from Wuhan city of China. The route of transmission of SARS-CoV-2 appears to be primarily via aerosols. Recent studies have shown that in airborne particles SARS-CoV-2 remain infectious for more than 3 hours. The infection caused by SARS-CoV-2 ranges from asymptomatic or subclinical cases with mild symptomatology to severe pneumonia, acute respiratory distress syndrome and death.
