[Factors affecting differentiation between <i>Oncomelania hupensis</i> and <i>Tricula</i> snails among schistosomiasis control professionals in Yunnan Province].

Schistosomiasis control professionals in Yunnan Province have a low accuracy rate for distinguishing between the morphology of <i>O. hupensis</i> and <i>Tricula</i> snails, and gender and classification of schistosomiasis epidemics in endemic foci are factors that affect their ability to distinguish. The presence of <i>Tricula</i> snails causes a high degree of interference with <i>O. hupensis</i> surveys in <i>O. hupensis</i> snail-infested areas of Yunnan Province. Reinforced training for distinguishing between <i>O. hupensis</i> and <i>Tricula</i> snails is required among schistosomiasis control professionals in Yunnan Province.
