对洞庭湖区１５个有代表性的血吸虫病流行村的血吸虫病流行各个环节进行了定量分析。发现血吸虫病人多集中在沿湖居住的居民中，男性以从事生产性接触疫水的感染率较高，女性则以从事生活性接触疫水感染率较高；血吸虫病情与感染历史及性别有关，也与年龄及感染度有关。各类传染源中以耕牛及外来流动人群为主，但不同疫区各类传染源在传播中的地位不同。易感地带的钉螺及感染性钉螺以草洲为多，感染性钉螺密度及分布与传染源的种类与数量有关，但不论感染性钉螺的分布范围如何，血吸虫病高危易感地带总是沿湖呈带状分布。
Quantitative analysis of schistosomiasis prevalence in 15 representative schistosomiasis endemic villages in Dongting Lake area was carried out. Found that schistosomiasis patients are more concentrated in the residents living along the lake, men engaged in productive contact with the higher prevalence of infected water, women engaged in living contact with higher prevalence of infectious water; schistosomiasis and infection history and gender, Also related to the age and degree of infection. Cattle and migrants are the main sources of infection of all kinds, but the status of different sources of infection in different affected areas is different. Susceptible zone of snails and infectious snails to the grassland as much, the density and distribution of infective snails and the source of infection and the type of quantity, but regardless of the distribution of infectious snails, high-risk areas of schistosomiasis always along the lake Was zonal distribution.
