Figure 5.
The endemic number of infectious humans varies in relation to: (a) the level of protection and the probability of having G6PD deficiency, (b) the latent period of hypnozoites and the probability of having G6PD deficiency with weak protection (σ = 0.7), (c) similar to (b) but with strong protection (σ = 0. 3). All of the probability of having G6PD deficiency, the level of protection, and the latent period of hyponozoites are important factors in determining the endemic level of P. vivax.
