From: Time-to-infection by Plasmodium falciparum is largely determined by random factors
Schematic of time-to-infection model. (A) Given a constant force of infection, the time-to-initiation of blood-stage infection is exponentially distributed. (B) After emergence from the liver, there is a distribution of parasite growth rates (shaded purple triangles). (C) Parasites grow until they reach the threshold for detection by PCR (red dots and lines) or microscopy (green dots and lines). It is then possible to compare the growth rates for individuals detected early (blue box in C, blue-shaded shape in D) or late (yellow box in C, yellow-shaded shape in D).
