由严重急性呼吸综合征冠状病毒2型（SARS-CoV-2）引起的冠状病毒病2019 （COVID-19）已成为全球大流行。与COVID-19相关的死亡人数每天都在迅速增加。SARS-CoV-2的主要传播途径是通过空气（空气传播）。本文详细介绍了SARS-CoV-2的空气传播、空气动力学以及不同的传播方式（如飞沫、飞沫核和气溶胶颗粒）。SARS-CoV-2可以通过感染者在呼气、咳嗽、打喷嚏和说话等活动中传播。在这些活动和一些医疗程序中，会形成被SARS-CoV-2颗粒污染的气溶胶和飞沫。根据它们的大小和环境条件，这些颗粒在空气中存活的时间不同，并可能在易感宿主中引起感染。很少有研究确定携带病毒的颗粒和飞沫引起感染的机制或空气动力学。在这篇综述中，我们讨论了SARS-CoV-2病毒颗粒可以在空气中传播并引起感染的各种形式。
Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a pandemic worldwide. On a daily basis the number of deaths associated with COVID-19 is rapidly increasing. The main transmission route of SARS-CoV-2 is through the air (airborne transmission). This review details the airborne transmission of SARS-CoV-2, the aerodynamics, and different modes of transmission (e.g. droplets, droplet nuclei, and aerosol particles). SARS-CoV-2 can be transmitted by an infected person during activities such as expiration, coughing, sneezing, and talking. During such activities and some medical procedures, aerosols and droplets contaminated with SARS-CoV-2 particles are formed. Depending on their sizes and the environmental conditions, such particles stay viable in the air for varying time periods and can cause infection in a susceptible host. Very few studies have been conducted to establish the mechanism or the aerodynamics of virus-loaded particles and droplets in causing infection. In this review we discuss the various forms in which SARS-CoV-2 virus particles can be transmitted in air and cause infections.
