abstract: OBJECTIVE
  To further master the Oncomelania hupensis snail situation in Huizhou District, so as to provide the evidence for improving the prevention and control work.
  
  
  METHODS
  According to the prevalence of schistosomiasis in history and the characteristics of residual snail points in recent years, the snail surveys were carried out with the environmental sampling and systematic sampling method in history snail environments and their surrounding suspicious environments.
  
  
  RESULTS
  Totally 5,298,940 m2 in 12 administrative villages of 3 townships were investigated and there were 24 406 m2 snail areas at 5 remaining snail spots in 4 administrative villages. The highest snail density was 283 snails/0.1 m2, and the average density of living snails was 2.31 snails/0.1 m2. A total of 4,303 snails were captured, 1,534 were checked by microscopy, and no infected snails were found.
