依据传染病防控基本原则,精准预防新型冠状病毒感染

Accurately prevent SARS-CoV-2 infections based on the basic principles of infectious disease prevention and control

新型冠状病毒肺炎(简称新冠肺炎,coronavirus disease2019,COVID-19)疫情暴发流行已两年,持续在全世界肆虐。由于各国采取的防控政策和措施不同,疫苗分配不均,加之新型冠状病毒(severe acute respiratory syndrome coronavirus 2,SARS-CoV-2)变异迅速,导致疫情仍十分严重。随着疫情的发展,对新冠肺炎的临床特征、流行病学及SARS-CoV-2的生物学特征等有了深入研究和认识。人群普遍接种疫苗在控制新冠肺炎疫情中起到决定性作用,但注射疫苗后仍然存在一定比例的突破性感染。因此,依据传染病防控基本原则(管理传染源、切断传播途径、保护易感人群)进行物理防护仍十分重要。实践证明,“普遍疫苗接种+有效物理防护”是全面控制新冠肺炎疫情的根本措施,两者不可或缺。

The novel coronavirus pneumonia(coronavirus disease 2019,COVID-19)pandemic has been raging around the world for almost 2 years.Due to the different prevention and control policies and measures adopted by various countries,uneven distribution of vaccines and rapid mutation of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),the pandemic is still very serious.With the process of the pandemic,in-depth research and understanding of the clinical characteristics and epidemiology of COVID-19 and biological characteristics of SARS-CoV-2 have been made.Widespread vaccination of the population plays a decisive role in the control of the COVID-19 pandemic.However,there is still a certain percentage of breakthrough infections after vaccination.Therefore,the physical protection is still very important based on the basic principles of infectious disease prevention and control(management of the source of infection,cutting off the route of transmission and protection of the susceptible population).Practice has proved that“widespread vaccination+effective physical precautions”is a fundamental measure for comprehensive control of COVID-19 pandemic,and both are indispensable.
