Seroprevalence of Anti-SARS-Cov-2 IgG Antibodies in Tertiary Care Hospital

Background: Seroprevalence of anti-SARS-CoV-2 IgG antibodies not only provides information for tracing the missing cases but also help in implying proper measures against the infection. We estimated the seroprevalence of SARS-CoV-2 specific IgG antibodies in Chandrapur, Maharashtra. Material and Methods: Blood samples were collected randomly from 6012 individuals who were SARSCoV-2 RT-PCR negative across Chandrapur, Maharashtra. The serum samples were tested for SARS-CoV-2 IgG antibodies using Enzyme linked Immunosorbent Assay (ELISA) method. Results: Anti-SARS-CoV-2 IgG antibodies were found in 32.97% samples with slightly more prevalence amongst males than females. Also, urban population and individuals in 21-40 age group showed higher positivity. Conclusion: This study implies the importance of anti-SARS-CoV-2 IgG antibody serosurveillance amongst RT-PCR negative individuals. This will help in interrupting the -spread of infection and making protocols in prevention of infection.
