目的 了解西昌市血吸虫病目前的流行现状 ,为制定防治策略提供依据。方法 采用 3送3检尼龙袋集卵孵化法和 Kato- Katz法对邛海湖周边地区的 2 0个自然村居民进行血吸虫感染率和感染度的调查。结果 检查 5 - 6 0岁居民 3415人 ,血吸虫感染率为 2 8.81% ,病人 EPG为 36 .0 7。各年龄组中 ,15 - 19岁组感染率最高 ,达 36 .0 2 % ,病人感染度 (EPG)以 5 - 9组最高 ,为 4 1.96 ,5 - 9岁、2 5 - 2 9岁、30 - 34岁 3个年龄组 IPC及 RIPC均高于其他年龄组 ;男女性别感染率及感染度无明显差异。文化程度及家庭经济收入高的血吸虫感染率低。种植烟草、蔬菜的居民感染率分别为72 .4 6 %和 4 9.5 3% ,高于其他职业人群。阶、梯地居民感染率及感染度明显高于平坝地区。结论 该地区血吸虫病流行仍较严重 ,居民感染率及感染度均高。血吸虫感染与当地居民的文化程度、家庭收入有密切关系 ,从事经济作物种植的居民感染率明显高于其它职业者。
Objective To understand the current epidemic situation of schistosomiasis in Xichang and provide the basis for making prevention and cure strategies. Methods The infection rate and infection rate of Schistosoma japonicum among 20 villages living in the surrounding area of Qionghai Lake were investigated by egg hatching method and Kato-Katz method. Results A total of 3415 residents aged 5-60 years were examined. The infection rate of schistosomiasis was 2 8.81%. The EPG of patients was 36.07. Among all age groups, the highest infection rate was found in the 15-19 age group (36.2%), and the highest EPG prevalence in the 5-9 group was 4 1.96, 5-9 years old, 25-29 years old, The age group of 30-34 years old had significantly higher IPC and RIPC than the other age groups. There was no significant difference in the infection rate and infection rate between male and female. Schistosomiasis infection rate is low with high education and family income. Residents infected with tobacco and vegetables were 72.46% and 4.953% respectively, higher than other occupational groups. Step, ladder residents infection rate and infection was significantly higher than the Pingba area. Conclusion The prevalence of schistosomiasis in this area is still serious, and the infection rate and infection rate among residents are both high. Schistosomiasis infection is closely related to the education level of local residents and family income, and the infection rate of residents engaged in economic crop cultivation is obviously higher than that of other professionals.
