长江抗洪抢险转退官兵血吸虫感染状况的调查研究

目的 在非血吸虫病流行区对参加９８长江抗洪抢险转退官兵开展血吸电病流行病学调查，为其它省区应付类似的突发事件提供可借鉴的经验，方法 制定实施方案和组织技术措施，受检者均做血吸虫病皮内试验，皮试阳性者再做间接血凝试验（ＩＨＡ），并结合临床症状、体征确定为血吸虫感染者，结果 实查 ２８１６人（占应检人数的７１．８２％），查出血吸虫病感染者３９人，阳性率为 １．３８％（３９／１８１６）．患者均获治愈，数据作统计分析。结论 进入血吸虫病流行区的抗洪抢险官兵中血吸虫感染者有地域分布特征，且采取防护措施者的血吸虫感染率显著低于未采取防护措施者（ｐ＜０．０５）。本次调查对其他省区卫生防疫部门应付类似的突发事件有指导性意义。

Investigation into the infectionus status of schitosomaiasis in the ex-officers and ex-soldiers participated in fighting the blood and taking rescue activities in the Yangtse valley

Objective To conduct epidemiological investigations of schistosomiasis infection in lgrge population of ex-officers and soldiers in non-schistosomiasis endemic areas and provide valuable experiences for antiepidemic activities in dealing with similar emergency in other provines. Methods: Epidemiological plan, organizational and technical measures were worked out, all the target population were examined by intradermal test and the positives were further tested with indirect hemoglutination(IHA), and schistosomiasis patients were asertained by intradermal test and IHA in combination with clinical signs and manifestations. Results: Totally 2 816 persons( accounting for 71 .82% of the target population) were investigated and 39 schistosomiasis patients were detected with a positive rate of 1 . 38%(39/2816) . All the patients were treated and the data statistically analyesd. Conclusion: The distribution of the patients entered into the Yangtse Valley Prevalent with schistosomiasis for fighting the flood and taking rescue activities was concentrated in the areas heavily prevalent with schistosomiasis. In addition, the infection rate in the ex-officers and soldiers with preventive measures was significantly lower than those without taking preventive measures( P < 0. 05). The results of investigation also showed that the plan and measures employed are practicable. This investigation is of directive significance in guiding the investigation of schistosomiasis infection in similar emergency carried out by anti-epidedemic departments in other provinces.
