“…This model is appropriate for diseases that spread quickly and give immunity to survivors, to example as the conventional SIR (SCHIMIT, 2010), but can, without loss of generality, be used to describe the installation of agricultural pests or spread of computer virus. In most varied lattices topologies, for instance, since the propagation processes, of the disease or information, are very similar (HASTINGS, 2003; PACHI, 2006). There are other models that take into account differences between the propagation mechanisms or even larger complexity in the individuals’ interaction, but they will not be treated in this work.…”

“…Using the law of mass action in epidemiology, we assume that the disease spreads at a rate proportional to the product of the fractions of susceptible and infectious populations, considering that individuals randomly encounter it (Pachi, 2006). Therefore, as defined in López-Flores et al ( 2021), we define the proportionality constant β as the product of the average number of individuals contacted by an infected individual per day and the probability of transmission, and is called transmission coefficient, which indicates the rate of new infections when a contact occurs between susceptible and infected individuals.…”
