New Delhi, May 4: Omicron sub-variant XBB1.16 has been found in 100 per cent samples in the northeast region, according to INSACOG data.
More than 1,300 samples of Omicron sub-variant XBB2.3 have been detected in India, while XBB.1.16 has become the dominant strain in the country.
The samples of XBB2.3 have been found across 24 states and Union territories.
At 307, the highest number of samples was found in Gujarat, followed by 183 in Delhi, 178 in Karnataka and 164 in Maharashtra, the Indian SARS-CoV-2 Genomics Consortium (INSACOG) data stated.
XBB1.16 sub-variant has been found in 100 per cent of samples in northeast India, 91.7 per cent of samples in central India, 75 per cent in south India, 67.1 per cent in west India, 52.8 per cent in north India, and 50 per cent in east India, it showed.
XBB.2.3 seems to be growing across the world, with the earliest samples found in mid-December in Karnataka and Delaware in the US. So, the origin is somewhat unclear, a senior scientist said.
Also, the domination of the XBB recombinant variant and its sub-lineages is almost complete in India, with XBB1.16 becoming the dominant strain in most of the country, he said.
