A new sub-variant of Omicron, called BA.2, has been spotted in a few countries. But should we be worried? According to the director of the Institute of Global Health in Geneva, it is to be watched.
Jean Castex has just announced some changes to health restrictions, while France has reached a new peak in contamination with more than 436,000 positive cases this Wednesday, January 19, 2022. At the same time, variants of Covid-19 continue to flourish around the world. After Delta and Omicron, a new sub-variant has been seen in a few countries around the world. Mutation of Omicron, it was baptized BA.2.
“We don’t know much yet. It has been spotted in several countries, such as Israel, Singapore, India and China.”, explains Professor Antoine Flahault, director of the Geneva Institute of Global Health, at LCI. “We do not know its origin, its virulence, or its ability to escape immunity, including that conferred by Omicron. On the other hand, it seems to be more contagious“, he continued. According to the scientist, BA.2 would already be in the majority in Denmark.
An increase in contamination to be expected?
According to Pr Antoine Flahault this new sub-variant should be taken seriously, unlike Deltacron for example. He assures that as this mutation has been spotted in several parts of the world, it will be necessary to look into it a little more to know in particular if it “escapes the immunity conferred by the vaccine and previous infections and learn more about its virulence.” He adds : “It’s unlikely, but it needs to be studied closely. Until we have the answer to this question, forecasting is a very perilous exercise.“It is therefore difficult to know whether BA.2 will be the cause of a new peak in contamination. According to the confidences of the scientist to the news channel, the solution to date remains to observe how the situation is Denmark: In France, we do not yet know to what extent this sub-variant has spread over the territory or if it is even present there.
