A brand new COVID-19 variant made up of two strains of Omicron is regarded as much more infectious than the one presently driving circumstances up world wide.
Well being officers are monitoring the pressure, known as XE, which was first detected within the UK however is now being reported in circumstances elsewhere.
It’s simply the most recent in a protracted line of variants that scientists are actually maintaining a tally of, because the world continues to battle coronavirus outbreaks.
XE: A hybrid variant of Omicron
Based on the UK Well being Safety Company (UKHSA), XE is a mixture of BA.1 and BA.1.
BA.1 is the unique Omicron variant, which sparked new waves of COVID-19 infections world wide and led to strengthened public well being restrictions in lots of international locations.

Ought to we fear in regards to the XE variant?
Dr. Simon Clarke, an Affiliate Professor in Mobile Microbiology on the College of Studying, instructed the AP information company on April 8 that it was too quickly to make judgements about XE.
"There's loads to be learnt about this recombinant virus,” he stated.
“That is the place two viruses have gotten collectively and mixed their genetic materials and you find yourself with a mosaic. It appears in the intervening time that it's not as match and as profitable as BA.2, though I believe it is nonetheless pretty early days”.
“When it comes to its potential to trigger illness, you possibly can't actually choose that till you have obtained a good variety of individuals contaminated, that is a way more troublesome willpower to make," he added.
The World Well being Group is holding tabs on XE however has not but deemed it a variant of concern or curiosity.
The place has the XE variant been detected?
XE was first detected through sequencing in England on January 19, 2022.
As of 5 April, the UKHSA stated there had been 1,125 circumstances in England, and the variant is believed to be spreading by group transmission, with nearly all of the circumstances presently within the east of England, London, and the South East.
