As France is deconfining, a cluster of at least 46 people infected with a very rare variant of the English strain of Covid-19 has just been discovered in the Bacalan district. This will lead to anticipating the vaccination of all adults unconditionally in this area.
Where does the cluster come from?
At least 46 people from this district in the north of Bordeaux – where the Cité du Vin is located, along the Garonne – have been detected as positive for a very rare variant of Covid 19 since the weekend of May 15-16, not to mention the return of the results of the first day of the massive screening launched Friday, May 21.
“During the screening of patients, it was found that there was an abnormality and suspected that it was not a usual English variant, but having a particular mutation, this was confirmed on sequencing”, said Professor Patrick Dehail, medical adviser to the director general of the Nouvelle-Aquitaine regional agency. “We have two transmission chains linked together on these 46 cases.” The track of an “intrafamilial departure” of the contamination, which would then have been transmitted to the school of the district, closed on Thursday, was evoked.
What do we know about this variant?
“This is a variant already identified at national level but very rare so far, explained Professor Dehail. It is a “Variant of concern” (VoC), that is to say worrying, as for example the English and Indian variants ”. At this point, five variants are classified as “Variants of concern” in France, according to the health agency: the English, South African, Brazilian, Indian variants, and the one detected in Bordeaux (counted with another, almost similar, called VOC 20I / 484K). The list of “Variants of concern” may vary by country depending on the local situation.

Especially since according to him, “The Bordeaux population is relatively naive about the virus”, in a region “Relatively spared” and or “Collective immunity is for the moment very low”.
