NEW COVID VARIANT. The XE variant is one of the recombinants of the Omicron BA.1+ BA.2 variant and is circulating worldwide. 10% more contagious than BA2, it makes the patient positive for 10 days. Case, danger, symptoms… The latest information on the XE variant of Covid and the situation in France.
[Mis à jour le 6 mai 2022 à 15h56] After the variants of Covid, recombinants. the XE variant is a †recombinant of the BA.1 and BA.2 subvariants (Omicron)“explained the dr. Maria Van Kerkhove, epidemiologist at the World Health Organization (WHO) on April 5. It would be 10% more contagious than BA.2 and would pollute longer infected patients: the PCR test would be positive for 10 days or more, much more than the usual 6,”which means the virus is more than opportunities to spread on a larger scale† said Professor Denis Kinane, Scottish immunologist, told The Mirror newspaper on May 3. †There are 470 XE variant case sequences until April 19 between UK, Denmark, Finland, Germany and IsraelSanté Publique France reported on April 20. In FranceXE is detected on “a very low level. What is this new XE variant † What are the? symptoms † what is being transfer † Is the dangerous † Update on current knowledge.

Definition: what is the XE variant?
The XE variant was first discovered on January 19, 2022 in England. That is “a recombinant of the BA.1 and BA.2 subvariantssaid World Health Organization (WHO) epidemiologist Dr Maria Van Kerkhove.Recombinant variants are not an uncommon phenomenon, especially when multiple variants are in circulation, and several have been identified to date during the pandemic. As with other variants, most will die pretty quicklysaid Professor Susan Hopkins, chief medical adviser to the British Health Security Agency (UKHSA). the majority of the virus (XE) genome belongs to BA.2.
Is the XE variant present in France?
In France†the BA.1/BA.2 XE recombinant is detected, but at a very low level : a sequence on the database on April 19″ reports Public Health France.
What are the symptoms of the XE variant?
Symptoms of the XE variant doesn’t seem to be any different from those of other variants and recombinants of the coronavirus. In Israel, the two patients with the XE variant”presented mild symptoms, including fever, headache, and muscle achesand did not require specialized medical care” the Haaretz media reported on March 16.
In which countries has the XE variant been detected?
► In England† The first case of the XE variant was detected lon January 19, 2022. “He currently represents less than 1% of the total number of consecutive cases. On March 22 there were 637 cases of XE variant in England† according to the UK Health Security Agency.
► In Israel† Two persons were detected as carriers of the combination of the BA.1 and BA.2 variants (the XE variant). †Both patients tested positive after undergoing a PCR test upon landing at Ben Gurion International Airport, and their samples were sequenced in IsraelThe Haaretz newspaper reported.
► In Thailand† the April 2, a first positive case to the XE variant was detected according to the Bangkok Post.
► In India : De first Indian case of the XE variant of the coronavirus was reported in Mumbai on 6 April according to the Brihanmumbai Municipal Corporation (BMC).
► To Canada † A case of XE variant was discovered in Quebec, the Journal des Montreal announced on April 7
► In New Zealand : The first case was formalized on Saturday, April 23, in a press release from the New Zealand Ministry of Health.
► In Spain† The first cases of XE variants were discovered on April 21. †According to information that has come to us from the UK, it is [le variant XE] has progressed at a faster rate than BA.2 . in recent weeks“says the Spanish Ministry of Health.
The XE variant is also detected in Denmark, Finland and Germany.
Is the XE variant more contagious than the others?
“The XE variant is 10% more infectious than the BA.2 subline but we are still studying itWHO Dr Maria Van Kerkhove told on April 6This particular recombinant, XE, has shown: variable growth rate and we can’t confirm yet if it has any real growth benefit [par rapport à BA.2]† So far there is not enough evidence to draw conclusions about transmissibility, severity, or vaccine effectiveness† nuanced Professor Susan Hopkins, chief medical adviser to the British Health Security Agency.
Is the XE variant dangerous?
The XE variant would infect longer infected patients: the PCR test would be positive for 10 days or more, much more than the usual 6,”which means the virus is more than opportunities to spread on a larger scale† said Professor Denis Kinane, Scottish Immunologist on 3 May. “There is no no worrying signal about XE† There is no particular severity associated to this new variant” indicated Étienne Simon-Lorière, head of the evolutionary genomics unit of RNA viruses, at the Pasteur Institute, on April 13.
