Droplet fate in indoor environments, or can we prevent the spread of infection ?

From the epidemiological point of view, the main pathway to infection spread is airborne transport. The droplet size is the most important factor affecting their dispersion and deposition on surfaces, it determines the survival of microorganisms within the droplets.
This paper is a review of the state of knowledge concerning mechanisms of droplet spread and the solutions available to minimize their spreading and thus to prevent infections.
