Figure 2.

High transmission season prevalence of parasitaemia with increasing distance from the nearest pond. Prevalence of Plasmodium falciparum parasitaemia is shown for school-aged children (5- to17-yrs, n = 560; clear bars) and adults (>17-yrs, n = 380; striped bars). Significant differences in prevalence were determined by Chi-squared analysis. *Significantly higher prevalence of malaria infection than further from the ponds (p < 0.001).
