新型冠状病毒变异株对新型冠状病毒疾病诊治及防疫的影响分析

Impacts of SARS-CoV-2 variants on diagnosis,treatment,and control of COVID-19

新型冠状病毒在全球多国陆续演变出多个变异株,传播力和危害性逐步累积增强。目前Delta变异株已侵入我国,造成了严重的危害。新冠病毒的持续变异,已成为全球关注的焦点。本文汇总分析各典型变异株的研究数据,从生物学角度探讨变异株对病原体检测、治疗、疫苗等方面的影响,以及病毒持续变异对防疫工作造成的冲击和应对策略。

Multiple variants of SARS-CoV-2 have appeared in many countries across the world and resulted in the gradual enhancement of viral transmission and infection.Recently,Delta variant invaded China and caused serious consequences.The continuous mutation of SARS-CoV-2 is turning into a critical topic of global pandemic control.By summarizing the studies of typical variants,this article analyzed the impacts of SARS-CoV-2 variants on diagnosis,treatment,and vaccination from the perspective of biology,and discussed the strategies on how to tackle the challenge of the continuous mutation.
