India records first case of BA.4 variant in Hyderabad


Hyderabad: The first possible case of an infection with the BA.4 variant of the Sars-CoV-2 has detected in India, people involved in the genome surveillance of the coronavirus have said, adding that  does not yet pose a concern since it is an offshoot of the Omicron variant, which has already spread widely in the country.

(INSACOG) in its latest bulletin said the BA.2 variant continues to be dominant in India. “BA.2.10 and BA.2.12 are BA.2 sub-lineages that have been detected and many old BA.2 sequences have been reclassified into these new sub-lineages. So far these sub-lineages are not reported to be associated with increase severity of disease,” said INSACOG in its latest bulletin on results of genome sequencing.

According to data submitted to GSAID during the past four weeks, 773 samples were of the Omicron variant, making it about 97.2% of the total submitted samples of the said variant. “Suspected recombinant sequences are under further analysis,” said the consortium in the bulletin.

The BA.4 variant was detected earlier this month detected in Hyderabad in samples taken from a traveller from South Africa, where this strain of Omicron has been causing the current Covid-19 wave, people aware of the matter said, adding that this information is subject to an official confirmation.
