Dynamics of the infection spread: a time evolution of five subpopulations for $d=2$, $p_e=0.5$, $p_i=0.5$, $p_q=0.1$ and $p_r=0.12$ and population density $D=0.46$; b Effect of population density on the fraction of maximum infection, $i_{max}$. Here population density $D=1$ indicates that all the lattice locations are occupied by people. Other parameters are kept same as before
