Fig 2. Active S. haematobium infections based on positivity to at least one test among urine microscopy, real-time PCR from self-collected swab and real-time PCR from operator-collected swab.

On x-axis are represented participants with active schistosomiasis; the numbers above bars represent the number of eggs/10 mL urine as indicated on the right y-axis. Triangles and dots indicate positivity on self-collected and operator-collected swab, respectively, at Ct values indicated on the left y-axis.
