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

Figure 1

Plasmodium transmission dynamics. (a) Illustration of the natural history of infection with the P. vivax parasite. The variables represent a classification of the population at any given age and time into six states: completely susceptible ( ๐‘† ); clinical malaria resulting from an infection in a completely susceptible individual ( ๐ผ 1 ); recovered with clinical immunity without any hypnozoites ( ๐‘… ); mild or asymptomatic infection resulting from exposure of recovered individuals ( ๐ผ 2 ); recovered with a certain degree of clinical immunity, carrying hypnozoites ( ๐ฟ 1 ); recovered with clinical immunity, carrying hypnozoites ( ๐ฟ 2 ). Description and values for the parameters can be found in Table 1. (b) P. falciparum transmission dynamics. This is a subset of the previous system which is retrieved by making ๐‘ 1 = 1 .
