有效通风作为对抗新冠肺炎的措施之一的重要性在世界范围内得到广泛认可。在日本，在疫情初期，即2020年3月，官方宣布了针对新冠肺炎的基本通风措施。世卫组织还在2021年12月首次使用了“远程气溶胶或远程空中传播”一词。基于日本政府2021年前的气溶胶感染控制措施，我们对隔断放置相关方法进行了实验，作为有效通风方法的一个要素。2022年7月，新型冠状病毒疾病控制政府小组委员会提出了一项关于有效通风方法的紧急建议，以防止两种类型的气溶胶感染：大气溶胶在气流上的感染和小漂浮气溶胶在房间内扩散的感染。他们还展示了设置防飞沫隔板的方法，根据这项调查结果，这些隔板不会阻碍通风。
The importance of effective ventilation as one of the measures against COVID-19 is widely recognized worldwide. In Japan, at the early stage of the pandemic, in March 2020, an official announcement was made about basic ventilation measures against COVID-19. WHO also used the term “long-range aerosol or long-range airborne transmission” for the first time in December 2021. Based on the aerosol infection control measures before 2021 by the Japanese government, we conducted experiments on methods related to partition placement as an element of effective ventilation methods. In July 2022, the governmental subcommittee on Novel Coronavirus Disease Control provided an emergent proposal about effective ventilation methods to prevent two types of aerosol infection; infection by large aerosol on the air current and infection by small floating aerosol diffusion in a room. They also showed the way of setting droplet prevention partitions, which do not block off ventilation based on this investigation’s results.
