摘要
目的了解喜德县消除血吸虫病后的传播风险因素和疫情变化趋势,为巩固血吸虫病防治成果及推动今后防治工作提供科学依据。方法收集2014—2020年喜德县血吸虫病防治资料,分析各年度、各乡镇的人畜血吸虫病情、螺情、自然和社会因素的变化情况,采用Excel 2010软件建立数据库并进行描述性数据分析,发现当地血吸虫病传播风险,并提出针对性的防控措施。结果2014—2020年喜德县累计查螺面积为3361.50万/m^(2),查出钉螺面积288.32万/m^(2),累计解剖钉螺46660只,未发现阳性钉螺。2014—2020年红莫镇、李子乡、东河乡和鲁基乡进行血清学检测人数分别为26351人次、14736人次、15968人次和7562人次,血检阳性率分别为1.90%、1.43%、1.43%和3.50%,对血检阳性者全部粪检,未发现病原学确诊病人。2014—2020年耕牛存栏数总体有所下降,从657头下降到122头;6年共检查耕牛1592头,未发现血吸虫病牛。结论喜德县环境复杂仍有钉螺分布,血吸虫传染源种类众多,人群血清学抗体阳性率较高、血吸虫病的传播风险仍然较高,须建立血吸虫病预警机制,加强血防综合治理,巩固血吸虫病消除成果。
Objective To understand the spreading risk factors and the trend of epidemic situation after the elimination of schistosomiasis in Xide County so as to provide a scientific basis for consolidating the results of schistosomiasis control and promoting future work.Methods Data on schistosomiasis control in Xide County from 2014 to 2020 were collected.Changes in human and animal schistosomiasis conditions,snail conditions,natural and social factors were analyzed in order to discover local schistosomiasis transmission risks and propose targeted prevention and control measures.Excel was used for data description and analysis.Results From 2014 to 2020,the total area of snails examined was 33.615 million square meters in Xide County,and 2.8832 million square meters were detected with snails.The total number of snails was 46660 dissected,and no positive snails were found.From 2014 to 2020,the number of blood tests in Hongmo Town,Lizi Township,Donghe Township,and Luji Township were 26351,14736,15968,and 7562,respectively.The positive rates of blood tests were 1.90%,1.43%,1.43%,and 1.43%,3.50%,respectively.All patients with blood positive feces were examined,and no patients with confirmed etiology were found.From 2014 to 2020,the number of cattle on the farm has been declining year by year from657 to 122.A total of 1592 cattle have been inspected in six years,and no schistosomiasis cattle have been found.Conclusion There are still some Oncomelania snails in Xide County,and high positive rates of blood tests.A sound early warning mechanism for schistosomiasis should be established,comprehensive management of schistosomiasis should be strengthened,and the achievements of Xide County in eliminating schistosomiasis should be consolidated in Xide County.
