Some signs point to greater pathogenicity of the new sublines of the Omicron BA.4 and Centaur coronavirus strains, immunologistNickolay Kryuchkov, M.D., says. "If we understand that the contagiousness will increase already weakly, the virus will adjust to immunity, the pathogenicity may jump up. There is indirect data that Omicron sublines, BA.5 and Centaur, are more pathogenic than BA.1 and BA.2," Kryuchkov said. According to URA.RU, a more pathogenic variant of the coronavirus, according to the specialist, may appear at the most unexpected moment; it is this variation in pathogenicity in the new dominant lines that poses the main danger.
