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 (); clinical malaria resulting from an infection in a completely susceptible individual (); recovered with clinical immunity without any hypnozoites (); mild or asymptomatic infection resulting from exposure of recovered individuals (); recovered with a certain degree of clinical immunity, carrying hypnozoites (); recovered with clinical immunity, carrying hypnozoites (). 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 .
