XBB remains the dominant variant

XBB – a virus formed from a combination of the omicron sub variants BA.2.75 and BA.2 – continues to be the dominant variant in India accounting for 70% cases. The Indian Sars-CoV-2 Consortium on Genomics (INSACOG), a network of laboratories monitoring genomic variations of Covid-19 virus in the country which held a meeting last week has not found the presence of any new variant in substantial numbers in the last 2-3 weeks.

To review the Covid-19 situation in India, INSACOG will hold a meeting tomorrow again. So far it has found XBB dominating in the country, followed by B2.75 which was earlier dominant and now accounts for 20% of the cases.

INSACOG has not seen any “unusual pattern” or “clustering” in the country. “Severity depends on population immunity and local epidemiology. In the last few weeks we have seen cases going down contrary to the trend seen by some other countries, a senior government official said.

He said Omicron and its sub variants are unlikely to cause serious disease as hybrid immunity is going to protect people. The INSACOG surveillance has found that India has all the Omicron sub-lineages which are circulating in China, but in miniscule numbers and no local clustering of these has been seen anywhere in the country. India has been preparing itself for any potential upsurge in Covid-19. A nationwide mock drill was held last month across healthcare centres.
