Figure 2. Histograms of Schistosoma haematobium egg counts and community piped water coverage for the re-infection cohort participants (n = 378).

Panel (A) shows the distribution of egg counts/10 mL among children observed at follow-up round 1 and 2, and panel (B) shows the distribution of community piped water coverage among all study participants. Community piped water coverage in the community surrounding each child was derived from the population-based 2007 piped water use survey conducted in all households in the study area.
