Introduction: Coronavirus belongs to the family of Coronaviridae, in the order of Nidovirales. It is formed by a positive sense single-stranded RNA, usually appearing spherical with the size of 80-120nm and with crown-like spikes on the surface. This large family of viruses is commonly circulating among vertebrates, such as camels, cats, and bats. Novel coronavirus COVID-19 has been identified as a new strain of coronavirus. It can cause viral pneumonia and dyspnea in humans.1

Objective: The objective of this study is to analyze the demographic aspect of the number of RTPCR tests performed in the virology laboratory, Department of Microbiology, AIMS, B.G. Nagara for a period of two years i.e, July 2020 To June 2022.

Materials and Methods: Nasopharyngeal and oropharyngeal samples collected from patients were subjected to RT-PCR testing using Emeril kit results were tabulated based on different demographic profiles.

Conclusion: In the present study with the overall data the strain causing the second wave was highly communicable and account for the highest infection rate and mortality. The least virulent strain was Omicron which caused the third wave. The positivity rate of our district was highest in the month of May 2021 (11.1%). Positivity was high in the age group of 40 years and above.
