Figure 1From: Revisiting the circulation time of Plasmodium falciparum gametocytes: molecular detection methods to estimate the duration of gametocyte carriage and the effect of gametocytocidal drugsModels describing change in gametocyte density and gametocyte prevalence over time. S, sequestered gametocytes; G, circulating gametocytes; E, gametocyte-negative infected individuals (i.e. gametocytes not yet released into circulation); I, gametocyte-positive individuals; ρ rate of release of gametocytes from sequestration into the bloodstream; μ, rate of decay/removal of gametocytes; f, rate at which gametocyte-negative individuals become gametocyte-positive; r, rate at which gametocyte-positive individuals become gametocyte negative.Back to article page
