大山区家畜交易与血吸虫病传播的关系(英文)

RELATIONSHIP OF THE LIVESTOCK TRADE TO SCHISTOSOMIASIS TRANSMISSION IN MOUNTAINOUS AREA

[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 。

Objectice] To study the relationship between the livestock trade and schistosomiasis transmission and to provide an evidence for making a strategy of schistosomiasis control in mountainous areas. [Methods] A retrospective survey and analysis was conducted to investigate the prevalence of schistosomiasis in both humans and livestock (cattle, horses, mules, donkeys and pigs), and the number and migration of livestock in Weishan County, Yunnan Province in 1980～1991. [Results] A positive correlation was found between the infection rate of residents and the numbers of livestock migration (R=0 9151, P <0 01). During 1980 to 1991 the infection rate was increased gradually along with the development of livestock husbandry, especially, from the economic reforms since 1984. In 1984 there was positive correlation in the infection rate both human and livestock (R=0 8458, P <0 05).The results show that the infection rates of livestock on sale including cattle, horses, mules, donkeys and pigs are 9 54%, 29 39%, 16 38%, 14 47%, 25 73% and 11 11%, respectively. [Conclusion] The infection rate of human and livestock arises by parallel. The high frequency of livestock trade resulted in serious spreading of the infection source of schistosomiasis. The migration of the infected livestock might be an important factor in transmitting schistosomiasis.
