Modeling the Effects of Relapse in the Transmission Dynamics of Malaria Parasites

Figure 2

Expected clinical malaria episodes and parasite prevalence at equilibrium, for both P. vivax and P. falciparum. (a) Bifurcation diagram, showing the influence of 𝛽 on the equilibrium levels of clinical malaria for P. vivax (blue) and P. falciparum (red). (c) Influence of 𝛽 on the equilibrium levels of parasite prevalence ( 𝐼 1 + 𝐼 2 ) for P. vivax (blue) and P. falciparum (red). (b) and (d) are similar to (a) and (c), respectively, but use 𝑅 0 as control parameter. For P. vivax, we used 𝑝 1 = 𝑝 2 = 0 . 2 5 . Dashed lines represent unstable equilibrium solutions, whilst full lines refer to stable endemic equilibria.
