By 2019 December saw a deadly virus starting to spread across wuhan city in china and started to spread across the globe by 2020 and was named as SARS-CoV-2. The Covid-19 variant spreading in India, namely the Delta variant is found to be more contagious and has been classified as ‘being of concern’ by the World Health Organization. RTPCR positive samples from a tertiary care hospital were subjected to sequencing after fulfilling the criteria as per the standard protocol. Out of 70 samples sequenced, B.1.617.2, AY.4, AY.6, AY.12 & Delta like variants were detected. The Delta variant B.1.617.2 was found to be the predominant strain. The sub lineage of Delta variant strain like AY.6 (1.4%), AY.4 (12 %), AY.12 (14%) were also detected. Delta –like variant was found in 20% of the samples sequenced. The results of sequencing might help to understand the characteristics of the strains prevalent during second wave of SARS-CoV-2 and would be helpful to tackle further infection of COVID.
