摘要: 全球新型冠状病毒肺炎疫情仍处于大流行状态,Omicron仍是全球优势株,约占全球基因序列的99%。全球多个地区正在经历第7波疫情,主要由Omicron变异株亚型BA.4和BA.5引起,目前对于Omicron变异株亚型BA.4和BA.5的流行病学特征尚不明确,给各国家和/或地区的疫情防控带来很大挑战。本文就Omicron变异株亚型BA.4和BA.5的发现与流行现状、潜伏期、传播力、临床症状、病死率、疫苗对其保护效果等方面的研究进展进行综述,以期为科学防控Omicron变异株亚型BA.4和BA.5所致疫情提供参考。

Abstract:

The global COVID-19 is still in a pandemic state, and Omicron is still the dominant variant in the world, accounting for about 99% of the global gene sequence. Many regions around the world are experiencing the seventh wave of the epidemic. This round of epidemics is mainly caused by Omicron subvariants BA.4 and BA.5, but the epidemiological characteristics of Omicron subvariants BA.4 and BA.5 are still unclear, bringing great challenges to the prevention and control of the epidemic in countries and regions. In this study, discovery and epidemic status, the incubation period, transmissibility, clinical symptoms, case fatality rate, and the protective effect of vaccines of Omicron subvariants BA.4 and BA.5 were reviewed, in order to provide reference for scientific prevention and control of Omicron subvariants BA.4 and BA.5.
