Abstract
OBJECTIVE: To evaluate the potential risk of schistosomiasis transmission so as to provide the evidence for formulating the control strategy. METHODS: snail status, wild faeces, and schistosome infection of the population from 2015 to 2017. RESULTS: . The occurrence rate of frames with snails was 5.41%. No schistosome-infected snails were found. The positive rate of schistosomiasis serological tests of the residents was 3.36%, but the stool examination positive cases were not found. A total of 58 wild faeces samples were collected but no schistosome infested cases were found. The risk levels of schistosomiasis transmission in both villages were Grade III. CONCLUSIONS: Although Chuxiong City has been in a low risk state of schistosomiasis transmission, the density of snails is still high, and there is a risk of infection source importation. In the future, the infection source control and snail control should be strengthened.
