Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can be transmitted via respiratory droplets, aerosols, and to a lesser extent, fomites. Defining the factors driving infectivity and transmission is critical for infection control and containment of this pandemic. We outline the major methods of transmission of SARS-CoV-2, focusing on aerosol transmission. We review principles of aerosol science and discuss their implications for mitigating the spread of SARS-CoV-2 among children and adults.
严重急性呼吸综合征冠状病毒 2(SARS-CoV-2)可通过呼吸道飞沫、气溶胶传播,在较小程度上也可通过接触传播。明确导致感染性和传染性的因素对于感染控制和大流行的遏制至关重要。我们概述了 SARS-CoV-2 的主要传播途径,重点介绍了气溶胶传播。我们回顾了气溶胶科学的原理,并讨论了它们在减轻 SARS-CoV-2 在儿童和成人中的传播方面的意义。
