In April 2021, co-circulation of Kappa (37%) and Delta (L452R/T478K, 59%) variants was recorded. During May and June 2021, the Delta variant became the predominant circulating variant, and this coincided with a significant decline in the number of COVID-19 cases. Of the 20 full genome sequences, six isolates each exhibited signature mutations of the Kappa and Delta variant. With several states witnessing a reduction in the number of COVID-19 cases, continuous monitoring of newer mutations and assessment of their effect on viru
