[目的 ]为探讨家畜交易与血吸虫病传播的关系 ,并为大山区制订血吸虫病防治策略和措施提供依据。 [方法 ]收集和分析云南省巍山县近 10年 (1980～ 1991)每年的人畜血吸虫病感染情况、家畜 (牛、马、驴、骡及猪等 )数量、家畜交易情况 ,并进行统计分析。 [结果 ]居民感染率同家畜数量呈正相关 (R=0 .915 1P<0 .0 1)。 1980年至 1989年间 ,随着家畜数量的增加。居民的感染率逐渐上升。尤其是 1984年经济体制改革后 ,畜牧业的迅速发展加剧了血吸虫病的流行 ;1984年后 ,人、畜感染率呈显著相关 (R=0 .845 8P<0 .0 5 ) ,表明巍山县 1990～ 1992年卖出家畜黄牛、水牛、马、骡和猪血吸虫阳性率分别为9.5 4%、 2 9.39%、16 .38%、14.47%、2 5 .73%和 11.11%。 [结论 ]人与家畜血吸虫的感染呈平行发展 ,由于家畜交易的频繁 ,造成了血吸虫病传染源的严重扩散 ,病人与病畜互为传染源 ,从而加剧了血吸虫病的流行
[Objective] The research aimed to discuss the relationship between the transaction of livestock and the spread of schistosomiasis, and provide the basis for the formulation of prevention and cure strategies and measures for schistosomiasis in the mountainous area. [Method] The annual infection rates of human and animal schistosomiasis, the number of domestic animals (cattle, horses, donkeys, mules and pigs) and livestock transactions in Weishan County of Yunnan Province during the past 10 years (1980 ~ 1991) were collected and analyzed and statistically analyzed . [Results] The infection rate of residents was positively correlated with the number of livestock (R = 0.915 1P <0.01). Between 1980 and 1989, as the number of livestock increased. Infection rate of residents gradually increased. Especially after the economic reform in 1984, the rapid development of animal husbandry exacerbated the prevalence of schistosomiasis. After 1984, there was a significant correlation between infection rates of humans and livestock (R = 0.845 8P <0.05), indicating that Weishan The positive rates of domestic cattle, buffalo, horse, mule and swine schistosomes sold between 1990 and 1992 were 9.54%, 9.39%, 16.38%, 14.47%, 25.73% and 11.11% respectively. [Conclusion] The infection of schistosomiasis in human and livestock was in parallel. Because of the frequent trading of livestock, the source of schistosomiasis was seriously spread, and the mutual transmission of patients and sick animals increased the prevalence of schistosomiasis.
