科学家强烈暗示，气溶胶可能是 2019 年冠状病毒病 (COVID-19) 传播的合理原因；然而，气溶胶传播仍然存在争议。我们调查了韩国首尔一栋公寓楼最近发生的 COVID-19 聚集性感染病例之间的流行病学关系。所有感染病例都是沿着建筑物的两条垂直线发现的，每条线都通过浴室内的单个风管连接以进行自然通风。我们的调查发现，除了通过浴室的单个通风管道传播感染外，病例之间没有其他可能的接触。第一个感染病例的病毒可以通过（反向）烟囱效应通过风道传播到楼上和楼下，这解释了垂直井中的空气运动。这项研究表明气溶胶传播，尤其是在通风不足的室内，这一点未被充分认识。
Scientists have strongly implied that aerosols could be the plausible cause of coronavirus disease-2019 (COVID-19) transmission; however, aerosol transmission remains controversial. We investigated the epidemiological relationship among infected cases on a recent cluster infection of COVID-19 in an apartment building in Seoul, South Korea. All infected cases were found along two vertical lines of the building, and each line was connected through a single air duct in the bathroom for natural ventilation. Our investigation found no other possible contact between the cases than the airborne infection through a single air duct in the bathroom. The virus from the first infected case can be spread to upstairs and downstairs through the air duct by the (reverse) stack effect, which explains the air movement in a vertical shaft. This study suggests aerosol transmission, particularly indoors with insufficient ventilation, which is underappreciated.
