XE Covid Variant
Subject: Science and Technology
Section: Biotechnology
Context: India has a confirmed case of the XE variant of Covid, according to the Indian SARSCoV2 Genomics Sequencing Consortium (INSACOG) bulletin. The Union Health Ministry is yet to confirm the same or issue a statement on the findings.
Concept:
- In the weekly bulletin for April 25, INSACOG said Omicron (BA2) is the dominant variant in the country.
- 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 increased severity of disease.
- Meanwhile, a multi-institutional study has again confirmed the airborne transmission of SARS-CoV-2, highlighting the need for masks to reduce the risk of contracting the virus.
XE Covid Variant:
- The XE variant of coronavirus is a sub-variant of Omicron, which caused the third wave of Covid-19 in India in January 2022.
- It is a “recombinant virus” that cross between two strains of the Omicron variant, namely BA.1, which is the original strain, and BA.2, which is the more infectious strain.
- This was first discovered in the United Kingdom in January 2022, and so far, more than 600 samples of XE have been found in different countries.
