【摘要】：目的掌握云南省血吸虫病疫情动态和影响因素,为制定防治措施提供依据。方法选择4个血吸虫病疫情较重的县(市)的4个村作为国家级监测点。按全国监测方案的要求,对监测点内居民进行血吸虫感染血清学筛查(IHA)和病原学检查,并开展监测点基本情况调查、家畜病情监测和螺情调查。计算和分析人群血检阳性率、粪检阳性率、家畜感染率、钉螺感染率和活螺密度等监测指标。结果 IHA共筛查4 310人,受检率为79.68%,阳性率为8.40%,洱源县前甸村阳性率高达12.53%。女性阳性率略高于男性,30岁及以上年龄段、农民、民工和初中文化程度者感染率较高。血检阳性者中未查出粪检阳性者。现存晚期血吸虫病病人24例。4村均未检出感染性家畜和钉螺,活螺平均密度为0.023 3~0.056 6只/0.1 m2。结论监测点村疫情已得到有效控制,云南省血吸虫病处于低流行状态。
[Abstract]:Objective to understand the epidemic dynamics and influencing factors of schistosomiasis in Yunnan Province, and to provide basis for making prevention and control measures. Methods four villages of four counties (cities) with severe schistosomiasis epidemic were selected as national surveillance points. According to the requirements of the National Surveillance Program, the residents in the monitoring sites were screened for (IHA) and etiology of schistosomiasis infection, and the basic conditions of the monitoring sites, the condition of domestic animals and the snail condition were investigated. The positive rate of blood examination, fecal examination, infection rate of domestic animals, snail infection rate and live snail density were calculated and analyzed. Results there were 4 310 people screened for IHA, the positive rate was 79.68, the positive rate was 8.40 and the positive rate was 12.53 in Qiandian Village of Eryuan County. The positive rate of female was slightly higher than that of male, and the infection rate of farmers, migrant workers and junior middle school students was higher. No fecal test positive was found in the patients with positive blood test. Infected domestic animals and snails were not detected in 24 cases of advanced schistosomiasis in 4 villages. The average density of live snails was 0.023 3,0.056 animals / 0.1 m2. Conclusion the epidemic situation has been effectively controlled and schistosomiasis in Yunnan Province is in a low prevalence state.
