POC-CCA = point-of-care–circulating cathodic antigen.
* All schoolchildren were followed for 30 days. All 15 study children were CCA Trace or 1+ when selected and fluctuated between Negative, Trace, and 1+ during the 30 days, as indicated by the number and percentage of times Negative, Trace, or 1+. All were Schistosoma mansoni egg negative by 4 Kato–Katz slides/stool sample per day, and miracidial hatching test negative throughout the 30 days.
† Egg-positive control subject. Seventeen times (94.1% of the time) this positive control subject had a CCA score of 2+ (not indicated in the Table).
