Maximum Equilibrium Prevalence of Mosquito-Borne Microparasite Infections in Humans

Figure 1

Plot of 𝐼^∗_𝑀 (3) as a function of the biting rate, 𝑎, calculated in two ways: (a) the red dotted line shows the number of infected vectors calculated with the host prevalence 𝐼^∗_𝐻/𝑁^∗_𝐻 directly derived from the numerical solution of the dynamics of system (1); (b) the blue dashed line shows the number of infected vectors calculated with the host prevalence 𝐼^∗_𝐻/𝑁^∗_𝐻 derived from (4). For 𝑎 such that 𝑅₀ is less than one, we have 𝐼^∗_𝐻/𝑁^∗_𝐻<0. For 𝑎 such that 𝑅₀ is greater than one, the two curves coincide.
