There's a theory that relative humidity indoors modulates transmission. At low humidity, water evaporates from droplets, making them lighter. The lighter they are, the longer they can stay suspended in the air. At higher humidity it is more likely for droplets to accumulate more water, which makes them heavier until they fall down. https://www.tropos.de/en/current-issues/press-releases/details/coronavirus-sars-cov-2-breitet-sich-bei-niedriger-luftfeuchtigkeit-in-innenraeumen-staerker-aus https://www.tropos.de/en/current-issues/press-releases/detai...
