The patients with the new variants of the virus don't have any severe symptoms so far. The new mutant might be more transmissible than any strain of COVID-19, World Health Organisation (WHO) had said last week when it was detected in the UK.
 
 
XE is a "recombinant" - a mutation of BA'1 and BA.2 Omicron strains. Recombinant mutations emerge when a patient is infected by multiple variants of Covid. The variants mix up their genetic material during replication and form a new mutation, UK experts said in a paper published in British Medical Journal.

The WHO had said that the new mutation XE appears to be 10% more transmissible than the BA.2 sub-variant of Omicron.

"Early-day estimates indicate a community growth rate advantage of 10 percent as compared to BA.2, however, this finding requires further confirmation," the global health body had added.

Of the 230 Mumbai patients whose samples were sent for genome sequencing, 228 are positive for Omicron, one Kappa and one XE. 21 of the total 230 patients had to be hospitalised, though none of them needed oxygen or intensive care. 12 of those hospitalised were unvaccinated and 9 had taken both doses.
