【摘要】：目的掌握云南省血吸蟲病疫情動態(tài)和影響因素,為制定防治措施提供依據(jù)。方法選擇4個血吸蟲病疫情較重的縣(市)的4個村作為國家級監(jiān)測點。按全國監(jiān)測方案的要求,對監(jiān)測點內(nèi)居民進行血吸蟲感染血清學篩查(IHA)和病原學檢查,并開展監(jiān)測點基本情況調(diào)查、家畜病情監(jiān)測和螺情調(diào)查。計算和分析人群血檢陽性率、糞檢陽性率、家畜感染率、釘螺感染率和活螺密度等監(jiān)測指標。結(jié)果 IHA共篩查4 310人,受檢率為79.68%,陽性率為8.40%,洱源縣前甸村陽性率高達12.53%。女性陽性率略高于男性,30歲及以上年齡段、農(nóng)民、民工和初中文化程度者感染率較高。血檢陽性者中未查出糞檢陽性者。現(xiàn)存晚期血吸蟲病病人24例。4村均未檢出感染性家畜和釘螺,活螺平均密度為0.023 3~0.056 6只/0.1 m2。結(jié)論監(jiān)測點村疫情已得到有效控制,云南省血吸蟲病處于低流行狀態(tài)。
[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.
