COVID-19: India’s first case of Omicron XE variant confirmed by INSACOG

Express News Service

NEW DELHI: Amidst a spike in Covid instances, the Indian SARS-CoV-2 Genomics Consortium (INSACOG) has lastly confirmed the presence of Omicron’s sub-variant XE, which is 10 % extra transmissible, in India.

The affirmation from INSACOG got here after XE – a recombinant variant of BA.1 and BA.2 sub lineages of Omicron – was reported from Maharashtra, Gujarat and Kerala. The Union well being ministry has but to touch upon the variant.

In a bulletin dated April 25, INSACOG stated one of many instances reported in India is that of the XE variant. However, INSACOG, collectively initiated by the Union Health Ministry and Department of Biotechnology (DBT) in 2020, didn’t specify from which state the recombinant variant was reported.

In India, Omicron BA.2 remains to be the dominant variant to this point.

BA.2, a model of Omicron reported globally, has propelled Covid-19 surges throughout Europe and the US.

INSACOG additionally stated that BA.2.10 and BA.2.12 – BA.2 sub-lineages – have been detected, and “many old BA.2 sequences have been reclassified into these new sub-lineages.”

So far, these sub-lineages aren’t reported to be related to elevated illness severity, it stated.

The pan-India consortium of 38 laboratories to watch the genomic variations within the SARS-CoV-2 stated that as in comparison with the earlier week, 12 states have proven a rise in Covid instances. In distinction, 19 states have proven a decline.

On April 6, the Maharashtra authorities had stated that the primary case of XE was detected in Mumbai following genomic sequencing from a pattern of a 50-year-old costume designer from South Africa.

But the Union well being ministry had instantly denied the variant’s presence in India.

Three days later, Gujarat additionally introduced that the primary XE case was detected after a person from Mumbai examined constructive for Covid-19 throughout his go to to Vadodara. In Kerala additionally, one case of XE was seen on April 22.

All three instances had been reported in March, however genomic sequence outcomes got here within the first week of April.

As Covid-19 instances began rising in India in April quickly after faculties opened and plenty of states lifted restrictions, together with the masks mandate, genomic sequencing discovered eight variants of Omicron, together with BA.2.12.

In nearly all of sequenced samples in Delhi, which is reporting 45-50 per cent of all energetic instances in India, BA.2.12 was detected. Many of those that examined constructive for Covid-19 in Delhi and the NCR area had been school-going youngsters.

The World Health Organisation (WHO) has labeled BA.2 as a variant of concern.
