目的调查武警某部驻血吸虫病流行区官兵血吸虫感染状况,并分析流行因素。方法采用酶联免疫吸附试验(ELISA)进行血吸虫抗体检测,同时进行与血吸虫感染相关的训练、生产和生活行为方式的问卷调查,调查血吸虫感染的途径。结果共调查12459名官兵,年龄18～36岁,均为男性,血吸虫ELISA阳性率为1.2%,后勤班阳性率高于战斗班,差异有统计学意义(P<0.05);来自疫区官兵的阳性率高于来自非疫区者(P<0.05);2150名官兵参与问卷调查,100%的被调查对象均知晓感染血吸虫必须接触疫水,均认为接触疫水的方式是参加抗洪抢险和下河游泳,75人(3.5%)认为接触河边露水可以感染,163人(7.6%)认为还有其他不明原因可以感染;营区所处的地理位置、营区结构及营区内粪便的无害化处理与血吸虫感染密切相关。结论武警某部驻血吸虫病流行区官兵血吸虫ELISA阳性率较低;营区所在的地理环境、营区的结构和官兵的生产行为、生活方式是导致血吸虫病流行的主要因素。
Objective To investigate the status of schistosomiasis among officers and soldiers of a certain armed police station in schistosomiasis endemic areas and analyze the epidemic factors. Methods The enzyme-linked immunosorbent assay (ELISA) was used to detect the antibody of schistosomiasis. Meanwhile, a questionnaire survey on the training, production and lifestyle behaviors related to schistosomiasis infection was conducted, and the way of schistosomiasis infection was investigated. Results A total of 12 459 officers and men aged 18-36 years were enrolled in this study. All of them were male. The positive rate of schistosoma japonicum ELISA was 1.2%. The positive rate of logistics class was higher than that of combat class. The difference was statistically significant (P <0.05) (P <0.05); 2,150 officers and soldiers involved in the questionnaire survey, 100% of the respondents were aware of infected Schistosomiasis must contact with water, are considered to be exposed to the way of water is to participate in flood fighting and the next River swims, 75 (3.5%) believed that exposure to river water dew was contagious and 163 (7.6%) believed there were other unidentified infections; the geographical location of camps, camp structures and the decontamination of manure in camps And schistosome infection is closely related. Conclusions The seropositive rate of schistosomiasis seropositive was low in some departments of Armed Police Forces in the endemic area of schistosomiasis. The geographical environment, the structure of barracks and the production behavior and life style of officers and soldiers were the main factors leading to the prevalence of schistosomiasis.
