POC-CCA = point-of-care–circulating cathodic antigen.
* All 15 study schoolchildren were followed up for 30 days. They were Schistosoma mansoni egg negative by four Kato–Katz slides/stool sample per day, and miracidial hatching test negative throughout the 30 days. They were all CCA Trace when selected and fluctuated between Negative and Trace during the 30 days, as indicated by the number and percentage of times Negative or Trace.
† Because of time constraint, a Kato–Katz S. mansoni egg–positive control subject of 35 years old was accepted (see details in Table 6).
