Covid – Omicron: what symptoms are most common with Deltacron also called XD variant? Responses from the Institut Pasteur

The Institut Pasteur has unveiled the conclusions of its first research on the famous recombinant. And some of them are unexpected.

The crisis from Covid-19 seems behind us. But as countries lift restrictive measureshere are some elements that send a shiver down your spine: starting with these figures of contaminationdown, yes, but spectacular. Despite everything, the peak of this “small” wave of BA.2 also seems to have passed.

Still remain the recombinant. Indeed, the high circulation of virus allows him to mutate. And even to recombine. In other words, two variants can associate and give birth to another variant. This is particularly the case of Deltacron. A recombinant Where hybrid since Delta and Omicronclosely monitored by the health authorities.

So much so that this Monday, April 4, the Pasteur Institute published the first conclusions of its research on this recombinant, available on the Research Square platform.

This research was conducted Etienne Simon-Lorière, head of the Evolutionary Genomics of RNA Viruses group, on 32 confirmed cases of XD variant (in other words Deltacron) and 6 suspected cases, detected in France between January 3 and March 9, 2022.

For starters, the median age of sufferers is 32.5, the same as Omicron (35). With the difference that many more young people are affected: 25.7% of the cases studied are under 20 years old, against 11.3% for Omicron.

Another finding is that all the cases listed were symptomatic. Here is the list of symptoms The most common :

– Headaches (61.1%).

– Fatigue/Exhaustion (58.3%).

– Cough (44.4%).

– Fever (38.9%).

– Muscle pain (33.3%).

With higher rates of loss of smell and you taste than at Omicron.

Two cases were hospitalized, but were discharged less than 24 hours after admission.
