Simulation landscape and interaction neighbourhood: a A zone of interest with $400\times 400$ cells. Density of small blue boxes represent population density. b A small sub-zone, denoting the distribution of susceptible and empty cells. c Interaction conventions: staying home, $d=0$; sphere of influence includes only first nearest neighbours denoted by $d=1$; sphere of influence includes first as well as next nearest neighbours denoted by $d=2$, and so on
