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.

Key words: Schistosomiasis, sampling survey, intensity of infection, mean
