HYDERABAD: A day after India's first case of BA.4 subvariant of Omicron was reported from Hyderabad, it has now emerged that the South African national, who tested positive for the variant, had enrolled himself under a corporate educational exchange programme in a city business school a week ago.
The authorities traced his infection after genome sequence data from both GISAID (Global Initiative on Sharing all Influenza Data) and Indian SARS–COV-2 Genomics Consortium (INSACOG) was revealed two days ago.
