血吸虫病是中华人民共和国（和其他地方）的主要公共卫生问题之一，严重威胁健康以及社会和经济发展。2007 - 2009年，湖北省江陵县实施了以传输控制为主，温室气体减排为辅的综合防治策略。选择了三个村庄进行试点研究，除常规控制措施外，还将牛从邻近的蜗牛出没的草地上赶走，改善卫生条件，建造家庭沼气生产单位。实施两年后，居民区钉螺感染率和感染强度均大大降低，而三个村的人血吸虫病患病率分别下降了29%、34%和24%。牛的迁移和沼气生产单位的建设产生了额外的积极影响，因为甲烷（CH 4）和二氧化碳（CO2）等温室气体的年平均排放量估计分别减少了7.8吨和80.2吨。
Schistosomiasis is one of the major public health problems in the People's Republic of China (and elsewhere), seriously threatening health as well as social and economic development. An integrated control strategy, emphasising transmission control but also aimed at reducing greenhouse gases, was carried out in Jiangling county, Hubei province from 2007 to 2009. Three villages were chosen for a pilot study involving removal of cattle from neighbouring, snail-infested grasslands, improving sanitation and construction of units for household biogas production in addition to routine control measures. Both prevalence and intensity of infection in the snails in the neighbourhood were greatly reduced after two years of implementation, while the prevalence of schistosomiasis in humans in the three villages had been reduced by 29%, 34% and 24%, respectively. The removal of cattle and construction of biogas production units had an additional positive effect in that the annual, average emission of greenhouse gases such as methane (CH4) and carbon dioxide (CO2) were reduced by an estimated 7.8 and 80.2 tons, respectively.
