The UK Health and Safety Agency (UKHSA) has confirmed that a recombinant variant of the Omicron sub-strain has been found in the UK, currently named XE! XE is a recombinant of Omicron BA.
1 and BA.
2 - however, this is not uncommon and has actually happened several times throughout the pandemic
.
However, not all recombinants turn into pandemics
.
At present, the number of people infected with XE in England is still very small, less than 1%
.
However, it is growing extremely fast, even 9.
8% higher than the fastest spreading BA.
2
.
It means that XE has the potential to be popular on a large scale
.
While experts are closely watching the new variant, UKHSA has assured people there is currently not enough evidence to draw conclusions about how it might have grown and spread
.
So far, 637 confirmed cases of the XE variant have been found in the UK! And the virus is spreading fast! Professor Susan Hopkins, UKHSA's Chief Medical Adviser, said: "Recombinant variants are not uncommon, especially when there are several in circulation and several have been identified over the course of the pandemic sofar
.
Like the variants, most die out relatively quickly
.
This particular recombinant XE shows variable growth rates and we can't say for sure if it has a real growth advantage
.
So far, there is not enough evidence to conclude Conclusions on infectivity, severity or vaccine effectiveness
.
UKHSA will continue to monitor the situation closely as normal as we process all data related to SARS-CoV-2 variants in the UK and internationally
.
"The World Health Organization warns all European countries to never underestimate or underestimate the dangers of recombinant strains! In addition to XE, there are two other recombinant strains that are currently attracting the attention of experts around the world - XF and XD
.
Delta and Omicron's There are two types of recombination, called XD and XF, both of which are Deltacron
.
Among them, XD is the recombination of Omicron BA.
1 and Delta variants
.
Among them, XF is the recombination of UK Delta and BA.
1.
A total of 38 people in the UK have been diagnosed, but The speed of transmission has not exceeded BA.
2 for the time being, so there is a high probability that it will not spread; since the discovery of XF in mid-February, a total of 38 cases have been confirmed by monitoring
.
A total of
49 cases have been confirmed in XD, mainly in France
.
There is a high probability that Deltacron cannot be widely popular
.
However, as soon as XE appeared, it reached 637 cases in the UK, so it is the most interesting
.
However, there is still very little information about XE
.
From this picture, XD is too close to Delta , so it is difficult to become popular, just as Delta was suppressed by Omicron
.
And XF, although most of BA.
1, but currently BA.
1 is being replaced by BA.
2, because of the speed of BA.
1's popularity Still lower than BA.

Only XE seems to have inherited the rapid spread of BA.

As for its toxicity, it remains to be seen

This may be due to the loss of six mutations (ins214EPE, S371L, G496S, T547K, N856K and L981F) from BA.
