武警部队官兵血吸虫病抗体水平与营区环境关系

Relationship between levels of antibody to schistosome of armed police officers and soldiers and their camp environment

目的了解驻长江中下游血吸虫病流行区武警部队官兵血吸虫感染情况及营区环境的影响。方法对驻疫区武警部队营区内外环境进行调查,并进行综合环境评分;采用ELISA法对官兵进行血吸虫抗体检测。结果共调查201个营区23 780名官兵,营区位于垸内亚型、洲滩亚型、洲岛亚型疫区的官兵血吸虫血检阳性率分别为1.88%、3.89%、4.73%;3种类型疫区综合环境评分为A级的营区官兵血检阳性率分别为1.23%、3.28%、3.33%,评分为B级营区血检阳性率分别为2.02%、3.81%、4.24%,评分为C级的营区血检阳性率分别为3.17%、5.79%、5.83%。结论武警部队官兵血吸虫感染情况与营区内外环境有一定关系,综合环境治理是部队血防工作关键之一。

Objective To understand the schistosome infection status of armed police officers and soldiers in endemic areas of the middle and lower reaches of the Yangtze River and the impact caused by the camp environment.Methods The inside and outside environments of camps were investigated and they were classified as Grade A,B and C according to scores.The levels of antibody to schistosome of the armed police officers and soldiers were tested with ELISA.Results A total of 23 780 officers and soldiers in 201 camps were investigated.The positive rates of antibody to schistosome of officers and soldiers stationed in the inner embankment areas,river beach areas and island areas were 1.88%,3.89% and 4.73%,respectively.In the aforementioned three types areas,the positive rates of antibody to schistosome of soldiers and officers in the camp environment scored as Grade A were 1.23%,3.28% and 3.33%,respectively,while the positive rates in the environment scored as Grade B were 2.03%,3.81% and 4.24%,respectively,and the positive rates in the environment scored as Grade C were 3.17%,5.79% and 5.83%,respectively.Conclusions There are certain correlation between the prevalence of schistosomiasis in armed police forces and the internal and external environments of their camps.The comprehensive environment management is one of the key measures of schistosomiasis control for armed police forces.
