Flow diagram illustrating epidemic spread and social distancing. At each time step t, a susceptible individual i modifies its infection radius ri,t + 1 in response to the local infection load Ii,t and current risk attitude αi,t. It then makes contact with all neighbours within its infection radius. Each contact with an infected neighbour may cause the susceptible to become infected, with probability p = 0.05. At each time step, infected individuals may recover with probability q = 0.2, and remain immune from then on
