Abstract:
After the optimization of control measures in December 2022，low-level SARS-CoV-2 infections have persisted in China.The predominant circulating variants globally are Omicron and its sublineages.Due to differences in mutation sites，various Omicron subvariants exhibit distinct characteristics in viral properties，clinical manifestations，and the effectiveness of vaccines and therapeutics.This review synthesizes the latest literature and epidemiological data on the six Omicron subviriants，including BA.5.2，BF.7，BA.2.75，XBB.1.5，EG.5 and JN.1，review their origin，virological characteristics，clinical characteristics in pediatric infection and prevention and control strategies，aiming to provide references for the prevention and control management of these variants and their offspring variants.
