【摘要】：目的分析近年来四川省肺吸虫病流行现状及流行趋势,为科学防治提供依据。方法选取10个点开展主动监测,在监测点进行人群病情、相关知识行为调查和中间宿主调查;在全省18个流行市(州)进行肺吸虫病病例报告登记,汇总分析病例报告。结果主动监测共调查2 949名居民,血清学阳性率为1.32%;回收调查合格问卷2 918份,20.49%的调查对象对肺吸虫病有所了解;34.51%的调查对象有生吃或半生吃溪蟹的行为,61.99%有玩耍溪蟹的行为,84.27%有喝生水行为;共捕获溪蟹2 154只,平均重量为25.5 g/只,感染率为13.83%,感染度为4.54,单只溪蟹感染囊蚴数最高为25个;采集拟钉螺388只,感染率为10.57%;2007年以来共登记报告肺吸虫病病例98例,主要集中于达州、泸州、宜宾三市,发病年龄主要在6~15岁,临床表现以肺外型为主。结论四川省肺吸虫病病例报告呈逐年上升趋势。流行区自然环境中存在肺吸虫传播链;流行区人群大多有不健康饮食行为习惯,若疏于防控,出现流行或暴发的可能性较大。
[Abstract]:Objective to analyze the epidemic status and trend of paragonimiasis in Sichuan Province in recent years, and to provide scientific basis for prevention and control of paragonimiasis. Methods Ten sites were selected to carry out active surveillance, and population condition, related knowledge behavior and intermediate host were investigated in the monitoring points, and the case reports of paragonimiasis were recorded and analyzed in 18 endemic cities (states) of the province. Results among the 2 949 residents surveyed, the seropositive rate was 1.32, and 2 918 questionnaires were collected, 20.49% of them knew about paragonimiasis. 34.51% of the respondents ate raw or semi-raw crabs, 61.99% played with crabs and 84.27% drank raw water. A total of 2 154 crabs were captured, the average weight was 25.5 g / mouse, the infection rate was 13.83, the infection degree was 4.54, the highest number of infected cysticercaria was 25 per crab, 388 Oncomelania hupensis were collected, the infection rate was 10.57. A total of 98 cases of paragonimiasis have been reported since 2007, mainly in Dazhou, Luzhou and Yibin cities. Conclusion the incidence of paragonimiasis in Sichuan Province is increasing year by year. There is a transmission chain of paragonimiasis in the natural environment of endemic areas, and most of the people in endemic areas have unhealthy eating habits. If they neglect prevention and control, the possibility of epidemic or outbreak is greater.
