This first French case would have been detected on March 28, in the Center-Val de Loire region.

Placed under surveillance by the World Health Organization, this new mutant of Sars-Cov-2 does not seem to cause more severe forms of the disease. It would also not be more contagious or more lethal than the original BA.1 (Omicron) source.

Its “cousin” BA.4, resulting from a “recombination” of BA.1 and BA.3, is also monitored.
