Figure 1.

Parasitemia, the proportion of infected mosquitoes, and intensity of infection after feeding on symptomatic and asymptomatic Plasmodium vivax carrier samples. (A) Asexual parasite density (log₁₀ parasites/μL) per clinical group. (B) Gametocyte density (log₁₀ gametocytes/μL) per clinical group. (C) Proportion of mosquitoes (percent infection) infected by asymptomatic and symptomatic carriers. (D) Intensity of infection (mean oocyst burden/total dissected mosquitoes in one feeding experiment) by asymptomatic and symptomatic carriers. (E) Correlation between sexual parasite density with the intensity of infection and infection rate in both symptomatic and asymptomatic carriers. The parasite density for both groups was calculated using microscopy. This figure appears in color at www.ajtmh.org.
