Hindustan Times. One recombinant that health authorities are tracking closely is a BA.1-BA.2 hybrid called XE, which was first detected in the United Kingdom in January.
About 600 cases have been reported, and scientists believe it may be about 10% more contagious than BA.2. The new XE variant of Covid-19 is not a matter of concern as it is not likely to cause any more severity than other sub-variants of Omicron (BA.1 and BA.2) did, Dr Gagandeep Kang, Professor at Christian Medical College in Vellore, said on Thursday. “Variants will come because people are travelling.
Of what we know of the variant (XE) is that it is not a point of concern," Kang said. “We were worried about BA.2 but it did not cause more serious disease than BA.1.
XE does not cause more serious disease than BA.1 or BA.2," she said on the sidelines of a panel discussion organised by John Hopkins Gupta-Klinsky India Institute The World Health Organisation (WHO) has issued warning against XE, a new variant of Omicron first detected in the UK.
