Figure 1. The dynamics of reinfection.

Panel A. The rates of reinfection in the clinical cohort are shown for each age group over time. The proportion uninfected is shown as a ‘survival curve’ for each age group. Patients were censored if they had missing values or were treated prior to reinfection. Blue triangle and blue line - C1, green diamond and green line - C2, orange square and orange line - C3, red circle and red line - A. Panel B. Schematic illustration of parasite growth in blood. Infection commences with an infected bite, followed by a liver stage of one week. Once the blood stage commences, rapid parasite growth (high PMR) will lead to early detection on infection. Factors that slow parasite growth in the blood will delay the time until detection. Panel C. Exponential fit to field study data for group C1.
