Seroprevalence of anti-SARS-CoV-2 IgG antibody among health care workers of anaesthesia departments from various hospital settings in India

BackgroundHealth care workers (HCWs) are the most susceptible group to get COVID-19 infection and this group always need special attention as they are the key human resource to contain this pandemic. ObjectiveTo track down the seroprevalence among a particular group of HCWs working in the anaesthesia department in hospital settings. Study designTwo rounds of serosurvey were done to track the dynamicity among the 128 and 164 HCWs participants in the first round and second round, respectively. 5 mL of blood was collected and IgG SARS-CoV-2 antibody was tested in Abbott Architect i1000SR. ResultsThe seroprevalence found in the first and second round was 12.5% and 38.4%, respectively. A significant number (n=61, 77.21%) of seropositivity came from the asymptomatic HCWs group as found in both the survey. There was no significant association among different age, gender and RT-PCR tested groups. ConclusionRoutine diagnosis of COVID-19 should be referred among HCWs to identify and act upon unrecognized SARS-CoV-2 infection.
