Evaluation of sars Cov -2 variants among RT-PCR tested positive Covid-19 patients at our teriary care hospital in Telangana State, India

Background: The initial reports of coronavirus disease 2019 (COVID-19) came out with an outbreak in Wuhan, China on 30 December 2019 [1,2], SARS-CoV-2 has been spreading worldwide and, as of 15 July 2021, there have been 188.13 million confirmed infections and 4.06 million deaths [3]. New variants are thought to be responsible for re-infections, either after natural infection or after vaccination, as observed in Brazil and the United States, respectively. There is evidence that re-infections are already happening in India; a recent survey identified a re-infection proportion of 4.5% from a pool of 1,300 participants infected between January 2020 and October 2020. Another concern about the emergence of new variants is the potential failure of RT-PCR tests for diagnostics. Failure to target the gene encoding the spike protein was observed during detection of the 501Y.V1 variant in the UK2. Aim and Objectives of the study: The aim and objective of the current study are to identify the lineages and calculate the prevalence among our population. Methodology: The work was initiated following approvals from the Institutional Ethical Committee
