Children surveyed in each study country (left columns). Center columns show observed prevalence of Schistosoma mansoni infection, as detected either in 1 or 3 daily stool specimens using standard Kato-Katz microscopy, or in 1 or 3 daily urine specimens using point-of-care assays for parasite circulating cathodic antigen (POC-CCA). The country-level median intensity of Kato-Katz-detected infections (in eggs per gram of feces, EPG) is indicated in the right-most column.
