Seroprevalence of Anti-SARS-CoV-2 Antibodies in COVID-19 Patients in Hyderabad, Sindh

Abstract

Aim: The world is affected by the severe acute respiratory syndrome coronavirus2 (SARS-CoV-2) pandemic. This virus has emerged as a human pathogen that can cause symptoms ranging from fever to Pneumonia, but it remains asymptomatic or mild. To better understand the virus's ongoing spread, identify those who have been infected, and track the immune response, accurate and robust immunological monitoring and SARS-CoV-2 detection assays are needed. Methods: The estimation of serology tests to assess the presence of antibodies to SARS-CoV-2 in COVID- 19 patients at Asian Institute of Medical Sciences (AIMS) and Isra University & hospital. 1229 patients were selected including males and females with the age being 25 to 65 years living in the territories from 1st August to 30th November 2020. The anti-SARS-CoV-2 test was performed by an electrochemiluminescence immunoassay analyzer. Results: Out of 1229 participants 206 (17%) were positive with COVID-19, and 1023 (83%) were negative. The results further revealed that a higher percentage of positive COVID-19 were detected in males in all age groups as compared to females, and most of them are affected at age of 46-65 years male 40 (24.69%) and female 14(17.5%). Conclusion: The seroprevalence of SARS-COV-2 antibodies has increased in the old age population, which may aid in determining the true number of infected cases. Although the current study is based on a small sample of participants, the findings suggest a study with a larger population to implement stronger and targeted interventions.
