PUNE: Omicron's BA.2, which caused the third wave in India, remains the dominant variant of the virus in the country, top officials overseeing genomic surveillance told TOI on Monday.
Recently, subvariants BA.4 and BA.5 - both capable of marginally faster spread than BA.2 - were detected in parts of the country (including in Maharashtra) raising fears of Covid surges. But Dr Sujeet Kumar Singh, director of the National Centre for Disease Control, confirmed on Monday that BA.2 continues to be dominant.
