Environmental Stability of Enveloped Viruses is Impacted by Initial Volume and Evaporation Kinetics of Droplets

Our study measured the impact of initial droplet volume (50, 5, and 1 µL) and relative humidity (RH: 40%, 65%, and 85%) on the stability of influenza A virus and bacteriophage Phi6, which is often used as a surrogate for enveloped respiratory viruses. We also evaluated SARS-CoV-2 under a limited set of conditions.本研究考察了初始液滴体积（50、5和1 µL）及相对湿度（relative humidity, RH：40%、65%和85%）对甲型流感病毒（influenza A virus）以及作为包膜呼吸道病毒（enveloped respiratory viruses）替代毒株的噬菌体Phi6（bacteriophage Phi6）稳定性的影响。此外，我们还在有限的实验条件下对新型冠状病毒（SARS-CoV-2）开展了相关评估。
