Example of time-dependent virus transmission. The parameters are as follows: N = 1000, M = 2000, t = 1. At the initial state, mmax was set to 100 and is reduced to mmax = 0 when the number of detected infections reaches 1% (10 people). Infected patients are infectious for 15 steps (five steps as non-detectable asymptotic persons and ten steps as a symptomatic and detectable patient). After fifteen steps, they are removed from the system: they cannot be infected nor become infectious a second time. Parameters are given in the figures.
