the BQ.1.1 sub-variant is on the rise in France

While the peak of contaminations seems to be reached as part of this new wave, this sub-variant of Omicron extends its presence.

In our country, and if we are to believe the latest figures from Public Health France, the number of Covid cases is stabilizing. However, in its latest report published on October 20, the number of patients remains “raised”and two increases appeared, namely those of critical care admissions (552, +8%) and deaths (390, +23%).

But there is another progression to note, and it is that of the presence of the BQ.1.1 subvariant of Omicron.

BQ 1.1: An impact not yet assessed

Indeed, if the BA.5 sub-lineage still constitutes the vast majority of cases of infection, the rate of BQ 1.1 between mid-September and mid-October increased from 2% to 16%. However, Public Health France advances:

However, it is still too early to assess the possible impact of BQ.1.1 on the dynamics of the epidemic.

That said, in other close countries such as Italy, the Netherlands, the United Kingdom, or more distant such as the United States, the trend seems identical.

What associated symptoms?

Admittedly, doctors have been able to observe vomiting or simple stomach aches. But the involvement of the Covid is not revealed.

If ever it were to be in the future, we must fear an epidemic difficult to control if the patients cannot make the link with the coronavirus (less tests carried out).

The Question of BQ Resistance 1.1

Experts have estimated that it would be more resistant. It would better evade the immune system, bypassing the action of antibodies due to the presence of mutations in a subregion of its protein peak. As for the severity of the infection, there is currently no indication that it is greater.

What development to expect? It is still early to assess it. According to Antony Fauci, medical adviser to the President of the United States, adds the evolution will depend “previous vaccinations, previous exposures and the region of the country in which you are located”.

Anyway it’s a fact, the Sars-Cov-2 virus continues to mutate, and a lot. But among the hundreds of sub-variants, few will come under close scrutiny.
