摘要
目的了解荆州市沙市区血吸虫病流行状况、变化趋势。方法2005—2010年每年4—5月对沙市区黄场村采取系统抽样法进行螺情监测，10月对6岁以上常住居民采用间接血凝试验（IHA）筛查，IHA阳性者采用kato—Katz法进行病原学检查，对全部存栏耕牛采用塑料杯顶管孵化法进行检查。收集每年防治措施、自然、社会因素等方面资料进行统计分析。结果2005—2010年黄场村人群血吸虫病IHA阳性率为16．47％-26．84％，呈上升趋势，粪检阳性率为2．13％一4．44％，呈下降趋势，耕牛感染率为1．56％-18．00％，呈波动下降趋势。钉螺面积、活螺框出现率、活螺平均密度均呈上升趋势。结论沙市区血吸虫病病情呈波动下降趋势，螺情呈上升趋势，须加强防治力度。
Objective To understand the changes of epidemic situation of schistosomiasis in Shashi District, Jingzhou City. Methods From 2005 to 2010, each year, from April to May, thestatus of Oncomelania snails were investigate by using the sys- tematic sampling approach; in October, the inhabitants aged over 6 years were screened by indirect hemagglutination assay （IHA） and the positive persons received the etiological examination （Kato-Katz technique）. All the farm cattle in pens were exam- ined by using the plastic cup jacking hatching method. The data of control measures, and the nature and society data were collect- ed annually. All the data were analyzed systematically. Results From 2005-2010, the positive rate of blood tests was from 16.47% to 26.84%, assuming an ascend trend; the positive rate of stool examinations was from 2.13% to 4.44%, assuming a down- ward trend; the infection rate of cattle was from 1.56% to 18.00%, assuming a downward trend in volatility. The area with snails, the appearance rate of frames with living snails, and the average density of living snails assumed ascend trends. Conclusion The prevalence of schistosomiasis presents a downward trend in volatility, and the snail status assumes a ascend trend. Therefore, the prevention and control measures still should be strengthened.
