项目摘要
Aerosols are defined as any solid or liquid particle suspended in a gas (e.g. air). Aerosols may be produced by humans (e.g. by breathing, speaking, coughing and sneezing), transported in the air, and inhaled. It is well known that aerosol particles are an important vector for the spread of infectious diseases such as tuberculosis and there is strong evidence for the aerosol transmission of SARS-CoV-1. The novel coronavirus, SARS-CoV-2, which causes the disease COVID-19, is carried in the nose and throat of those infected regardless of whether they are symptomatic or asymptomatic and has been shown to remain viable in an aerosol and on surfaces. It is not yet known if SARS-CoV-2 is transmitted directly or indirectly by aerosols or what role or relative importance aerosols may play in its transmission. However, it must not be ruled out that aerosol transmission of SARS-CoV-2 is a possible mechanism for the spread of COVID-19. This work aims to test the hypothesis that SARS-CoV-2 may be aerosolized by natural expiratory events (i.e. by breathing, speaking and coughing) by using established techniques for characterization of aerosols and identification of viruses. The results may inform infection control interventions in Canada and worldwide.
气溶胶被定义为悬浮在气体(例如空气)中的任何固体或液体颗粒。气溶胶可以由人类产生(例如通过呼吸、说话、咳嗽和打喷嚏),在空气中运输和吸入。众所周知,气溶胶颗粒是结核病等传染病传播的重要媒介,并且有强有力的证据表明SARS-CoV-1的气溶胶传播。引起COVID-19疾病的新型冠状病毒SARS-CoV-2在感染者的鼻子和喉咙中携带,无论他们是否有症状或无症状,并且已被证明在气溶胶和表面上保持活力。目前尚不清楚SARS-CoV-2是否通过气溶胶直接或间接传播,或者气溶胶在其传播中可能发挥什么作用或相对重要性。然而,不能排除SARS-CoV-2的气溶胶传播是COVID-19传播的可能机制。这项工作的目的是测试的假设,SARS-CoV-2可能通过自然呼气事件(即呼吸,说话和咳嗽)气溶胶通过使用已建立的技术表征气溶胶和病毒的识别。这些结果可能会为加拿大和世界各地的感染控制干预提供信息。
