From 23 July to 9 September 2022, 38 SARS-CoV-2 complete genomes were sequenced. Genomics data reveals that only Omicron variants were circulating in Dhaka City; 26 Omicron BA.5 and 12 Omicron BA.2. Initially, Omicron BA.5 was the only circulating subvariant, then a major shift was observed from BA.5 to BA.2 during the last 3 weeks (Fig.1). During this period, 2 new subvariants emerged, i.e. BA.2.75 (n=6), and BJ.1 (n=1) from the parent BA.2. This emergence of new subvariants is most likely responsible for the current surge of COVID-19 infection in the country.
