Comparison of stochastic and deterministic models for gambiense sleeping sickness at different spatial scales: A health area analysis in the DRC
Fig 2
The purple and blue boxes denote the low-risk and high-risk human infection states, respectively. Low-risk people, who randomly participate in active screening are given the subscript H1 and high-risk people, who do not participate, have the subscript H4 (this notation is used to align with previously published versions of this model). Tsetse dynamics are given by red boxes. All rates given by arrows are exponentially distributed, except where stated as Erlang. A proportion fA = 1 − fH of tsetse bites will be taken on non-human animals, but this does not contribute to the infection dynamics. This figure is adapted from Crump et al. [8] under a CC-BY licence.
