Two species of snails, namely, Tricula fujiansis and Semisulcospira libertina were found, but only the former was the first intermediate host. The infection rate of snails was 0.7%(4/569).
Being aware of the distribution of Tricula snails in the basin of Lanchang River (the upper reaches of Mekong River) in Yunnan Province of China, investigations were carried out since 1981.
