@i_petersen @CathNoakes @BallouxFrancois That's an important question but not the only one. There are people who would like to (or have no choice to) particulate in at least some aspects of society while being exposed to less transmission. Clean air at least in a number of essential facilities would facilitate this.
@i_petersen @CathNoakes @BallouxFrancois 这是一个重要的问题，但不是唯一的问题。有些人希望（或别无选择）至少在社会的某些方面出现微粒，同时减少传播。至少在一些基本设施中的清洁空气将有助于实现这一目标。
