Delta新冠病毒变异株的特性及流行现状与防控研究进展

Research progress on characteristics, epidemiology and control measure of SARS-CoV-2 Delta VOC

新型冠状病毒疫情目前已在全球大流行,随着新型冠状病毒(Severe acute respiratory syndrome coronavirus 2,SARS-CoV-2)不断进化和变异,相继出现多种关切变异株。Delta新冠变异株(原称B.1.617.2)具有传播力强、感染潜伏期短、致病性强、发病进程快等特点,逐渐成为印度乃至全球主要的流行毒株,并导致多个国家和地区的疫情反弹。本文就Delta新冠变异株现阶段流行特点及核心防控措施进行综述。

COVID-2019 has become a global pandemic,and a variety of SARS-CoV-2 variants have emerged with the continuous evolution and variation.SARS-CoV-2 Delta VOC(B.1.617.2)has the characteristics of strong transmission,short incubation period of infection,high pathogenicity and rapid disease progression,which has gradually become the main epidemic strain in India and even in the world,leading to countries and regions of the epidemic rebound.In this paper,the current epidemic characteristics and core control measures of SARS-CoV-2 Delta VOC was reviewed.
