Figure 2

Travelling wave solution. (a) The susceptible population per unit area and (b) the infected population per unit area are plotted as functions of x for t between 30 (left most) and 60 (right most), plotted in time steps of 10. Here, \(S(0,0) = 0.4\), \(I(0,0)= 1.285451998\), \(G(0,0)= 0.8186870039\), and other parametric values are as given in the text.
