The<unk>  is a simple model of the airborne transmission of infectious diseases, developed by William F.<unk>  and Richard L.<unk>  for tuberculosis and measles.<unk><unk>  can also be applied to other diseases transmitted in the air, such as COVID-19. The model describes the situation where one or more infected people are sharing a room (and so the room air) with other people who are susceptible to infection. It makes predictions for the probability that a susceptible person becomes infected. The prediction is that infection is more likely for small poorly ventilated rooms, and if the infected person is highly infectious. The<unk><unk>  is a highly simplified model of a very complex process, but does at least make predictions for how the probability of infection varies with things within our control, such as room ventilation.
