  本文選題：血吸蟲病　切入點(diǎn)：哨鼠　出處：《中國(guó)血吸蟲病防治雜志》2017年02期

【摘要】：目的在云南省部分血吸蟲病流行區(qū)開展重點(diǎn)水域哨鼠監(jiān)測(cè),以提升血吸蟲病監(jiān)測(cè)系統(tǒng)的敏感性、完善監(jiān)測(cè)預(yù)警機(jī)制。方法選擇3個(gè)疫情較重縣(市)的6個(gè)自然村作為監(jiān)測(cè)點(diǎn),開展重點(diǎn)水域哨鼠預(yù)警監(jiān)測(cè)。對(duì)回收飼養(yǎng)后成活的哨鼠進(jìn)行解剖觀察,檢測(cè)血清抗體水平,并觀察監(jiān)測(cè)點(diǎn)人畜疫水接觸情況。此外,收集近3年來監(jiān)測(cè)點(diǎn)疫情資料并進(jìn)行分析。結(jié)果共投放哨鼠282只,回收256只,死亡8只,總回收率90.78%,總死亡率3.13%。有蟲卵肉芽腫結(jié)節(jié)的哨鼠數(shù)、檢獲成蟲數(shù)、蟲荷數(shù),以及血清抗體陽性率均為0。接觸疫水人員主要為村民和學(xué)生,接觸方式主要為收種作物和戲水。近3年來,監(jiān)測(cè)點(diǎn)釘螺面積、人群感染率和耕牛感染率均呈下降趨勢(shì)。結(jié)論云南省3個(gè)監(jiān)測(cè)縣(市)均未發(fā)現(xiàn)血吸蟲感染陽性哨鼠,人畜感染血吸蟲的風(fēng)險(xiǎn)較低。但加強(qiáng)重點(diǎn)水域的哨鼠預(yù)警監(jiān)測(cè),繼續(xù)落實(shí)以傳染源控制為主的綜合防治措施,仍應(yīng)是今后血防工作的重點(diǎn)。
[Abstract]:Objective to improve the sensitivity of schistosomiasis surveillance system and improve the early warning mechanism of schistosomiasis in some endemic areas of Yunnan Province.Methods six natural villages in 3 counties (cities) with severe epidemic situation were selected as monitoring points to carry out sentinel rat early warning surveillance in key water areas.The surviving sentinel rats were dissected, the serum antibody level was detected, and the contact of human and animal epidemic water was observed.In addition, the data of epidemic situation in monitoring sites were collected and analyzed in recent three years.Results 282 sentinel rats were put in, 256 were recovered, 8 died, the total recovery rate was 90.78 and the total mortality was 3.13.The number of sentinel rats with egg granuloma nodule, the number of adults seized, the number of worm load, and the positive rate of serum antibody were all 0. 5%.Contact with infected water mainly for villagers and students, the main way of contact with crops and water.In the last three years, the snail area, the infection rate of population and the infection rate of cultivated cattle all showed a decreasing trend.Conclusion there were no positive sentinel mice infected with Schistosoma japonicum in 3 surveillance counties (cities) of Yunnan Province, and the risk of schistosomiasis infection in humans and animals was lower.But strengthening the sentinel surveillance in key water areas and continuing to carry out comprehensive prevention and control measures based on the control of the source of infection should still be the focus of the future work of blood control.
