Abstract
AIM: To set up statistical methods for calculation of intensity of schistosome infection in residents in nationwide sampling survey of schistosomiasis. METHODS: Based on the epidemiological survey of schistosomiasis and according to the medical statistics for multiple stratifying and clustering random sampling, the calculation method on intensity of schistosome infection was inferred. RESULTS AND CONCLUSION: Nine formulas were worked out for the calculation of the intensity of schistosome infection in different endemic provinces with different ecotypes. These formulas are of practical value.
