Dear All,
Here is a simple model for the "infectivity" per unit time of a room with covid-containing droplets that fall to the ground at the limiting velocity of Stokes's drag in air. If anyone wants to build on this please feel free to do so, but let me know what is going on. If you like I can sent you the LaTeX file. I am not averse to collaborating, but I am too ignorant at the moment to take this simple model much further.
Stay safe!
Wayne
