The current coronavirus disease 2019 (COVID-19) outbreak vividly demonstrates the burden that respiratory infectious diseases impose in an intimately connected world. Unprecedented containment and mitigation policies have been implemented in an effort to limit the spread of COVID-19, including travel restrictions, screening and testing of travelers, isolation and quarantine, and school closures. A key goal of such policies is to decrease the encounters between infected individuals and susceptible individuals and decelerate the rate of transmission. Although such social distancing strategies are critical in the current time of pandemic, it may seem surprising that the current understanding of the routes of host-to-host transmission in respiratory infectious diseases are predicated on a model of disease transmission developed in the 1930s that, by modern standards, seems overly simplified. Implementing public health recommendations based on these older models may limit the effectiveness of the proposed interventions.

湍流气体云和呼吸道病原体排放

当前的 2019 年冠状病毒病 (COVID-19) 爆发生动地展示了呼吸道传染病在密切联系的世界中所造成的负担。为了限制 COVID-19 的传播,已经实施了史无前例的遏制和缓解政策,包括旅行限制、旅客筛查和检测、隔离和检疫以及学校停课。此类政策的一个关键目标是减少感染者和易感者之间的接触并降低传播速度。尽管这种社会疏远策略在当前大流行时期至关重要,但目前对呼吸道传染病宿主间传播途径的理解基于 1930 年代开发的疾病传播模型,这似乎令人惊讶,按照现代标准,似乎过于简化了。实施基于这些旧模型的公共卫生建议可能会限制拟议干预措施的有效性。
