Figure 1

Prevalence and parasite density by blood smear (BS) and PCR/LDR-FMA. Panels A and B illustrate the proportion of study participants with infections measured by BS (A) and PCR/LDR-FMA (B) each week of the study. The parasite density (mean + SD) was calculated from infection positive samples as measured by BS (C) and PCR/LDR-FMA (D). No statistical difference was detected in BS parasite densities between weeks 3–11, but an increase in parasite densities measured by PCR/LDR-FMA was detected (weeks 3–11; Kruskal-Wallis test, p < 0.0001). The number of infected samples by BS by week: 0 (n = 116), 1 (n = 0), 2 (n = 0), 3 (n = 10), 4 (n = 36), 5 (n = 61), 6 (n = 69), 7 (n = 80), 8 (n = 72), 9 (n = 79), 10 (n = 75), 11 (n = 67). The number of infected samples by PCR/LDR-FMA by week: 0 (n = 112), 1 (n = 39), 2 (n = 25), 3 (n = 52), 4 (n = 73), 5 (n = 81), 6 (n = 83), 7 (n = 99), 8 (n = 85), 9 (n = 103), 10 (n = 118), 11 (n = 94).
