Care home scenario. Each individual is represented by a cylinder and gives a colour according to their infection status. The concentration of infectious aerosols is represented using a colour scale. Two snapshots of the simulation are shown at (a) 8:30 a.m. (all individuals are resting in their bedrooms) and (b) 5:30 p.m. At 5:30 p.m., three more individuals are likely to be infected.
