INSACOG on Sunday confirmed the presence of BA.4 and BA.5 subvariants of Omicron in India, saying the disease was not severe in those infected with these subvariants.
According to the Indian SARS-CoV-2 Genomics Consortium (INSACOG), the two cases have been found in Tamil Nadu and Telangana.
BA.4 and BA.5 are subvariants of the Omicron variant circulating globally. These were reported first from South Africa earlier this year and are now reported from several other countries. These variants have not been associated with disease severity or increased hospitalization.
