PUNE: Three new and highly transmissible "offspring" of Omicron's BA.2 subvariant have been detected in India.
BA.2.74, BA.2.75 and BA.2.76 are "fitter" and more infectious than Omicron's BA.5, a senior scientist from the Indian SARS-CoV-2 Genomics Consortium (INSACOG) told TOI on Sunday, adding that they may be behind the ongoing surge in cases along with BA.2.38, which was identified in mid-June.
