Parasitological methods for the evaluation of schistosomiasis tend to be limited when parasitic burdens are low, which is a major characteristic of low intensity transmission areas.

Our main hypothesis is that HT has limitations and cannot be recommended for diagnosing light infections or as a control of cure.
