估量人体血吸虫寿命的资料来自病例报告及社群患病率分析两方面。血吸虫病患者离开流行区到非流行区定居后发现血吸虫卵的最长年限;埃及血吸虫为27年(Berbertan,1953),曼氏血吸虫为32.5年(Harris,1984),日本血吸虫为46年(Hall等,1980)。 从流行区一个社群不同年龄组患病率用数学模型的分析结果,Hairston(1973)及Warren(1973)认为平均寿命在2～5年之间,即埃及血吸虫为3.8年,曼氏血吸虫为3.5年,日本血吸虫为4.5年。根据埃及血吸虫、曼氏血吸虫及日本血吸虫每年自然消失30、34及25％计算,三种血吸虫留存1％虫数的年限分别为12、11及16年。
Information on the life expectancy of human schistosomiasis comes from both case reports and community prevalence analyzes. Schistosoma japonicum for 27 years (Berbertan, 1953), Schistosoma mansoni for 32.5 years (Harris, 1984), and Schistosoma japonicum for 46 years (Hall Et al., 1980). From the epidemiological analysis of the prevalence of different age groups in a community using mathematical models, Hairston (1973) and Warren (1973) found that the average life expectancy is between 2 and 5 years, ie, Schistosoma mansoni is 3.8 years. Schistosoma mansoni is 3.5 years, Schistosoma japonicum is 4.5 years. According to the fact that schistosoma schistosomiasis, Schistosoma mansoni and Schistosoma japonicum naturally disappear by 30, 34 and 25% annually each year, the three schistosomes retain 1% of their worms for 12, 11 and 16 years, respectively.
