From: Modelling knowlesi malaria transmission in humans: vector preference and host competence
(A) Vectorial Capacity as a function of human host preference when humans are dead-end hosts (i.e. C H = 0). The black line corresponds with equal human and macaque density (H:M); blue with H:1/3M; red with H:3M. (B) Vectorial Capacity as a function of human host preference when humans are competent hosts. Colours correspond with (A), broken lines denote vectors that are 'exclusive' in their host choice and solid lines denote 'mixed' preferences. (C) The effect of variable parasite infectivity as a function of its transmission route. Purple corresponds to a parasite that transmits human to mosquito to human more effectively (line, CH:1/2CM; cross markers CH:1/4CM), and green corresponds to a parasite that transmits macaque to mosquito to human more effectively (line, CH:2CM; cross markers CH:4CM). Unless stated otherwise we use H:10V; H:M; C H :C M (= 0.05); b = 0.25; g = 0.15 and T = 10.
