All statistics were calculated using data from 29 individual experimental infections.

^a Child age in years, ^b Trophozoite density per ml of blood, ^c Gametocyte density per ml of blood, ^d Number of mosquitoes offered a blood meal, ^e Number of mosquitoes that took a blood meal, ^f Number of mosquitoes dissected seven to eight days following infection, ^g Number of mosquitoes that died between feeding and dissection, ^h Number of mosquitoes with at least one midgut oocyst, ⁱoocyst intensity (average number of midgut oocysts in mosquitoes with ≥1 midgut oocyst).
