摘　　要：严重急性呼吸综合征冠状病毒2(SARS-CoV-2)的一种新亚变体EG.5在全球占据主导地位,它于2023年2月17日被首次报告,7月19日被世界卫生组织(WHO)指定为受监测变异株(VUM)。EG.5及其亚分支EG.5.1、EG.5.1.1等是奥密克戎变异株XBB.1.9.2的后代谱系。经WHO评估,EG.5及其亚分支于2023年8月9日被指定为关注变异株(VOI)。本综述旨在通过对文献及数据库检索分析,对EG.5及其亚分支流行病学特征进行总结,为新冠病毒防控策略的制定提供科学建议,以期更好地控制新冠疫情。EG.5, a novel subvariant of Severe Acute Respiratory Syndrome Coronavirus 2(SARS-CoV-2),was globally dominant and was reported for the first time on Feb 17, 2023. It was designated as a variant under monitoring(VUM) by the World Health Organization(WHO). EG.5 and its sublineages EG.5.1, EG.5.1.1 were the progeny lineages of the Omicron variant XBB.1.9.2. EG.5 and its sublineages were designated as a variant of interest(VOI) by the WHO on Aug 9, 2023. The review aims to summarize the epidemiological characteristics of EG.5 and its sublineages by analyzing literatures and retrieving data from databases so as to provide scientific bases for developing prevention and control strategies for SARS-CoV-2 and control the COVID-19 epidemic.
