目的探索近十年广西新发现的残存钉螺的分布特点及流动人口血吸虫病感染情况,为血吸虫病防治提供科学依据。方法根据查到残存钉螺年份长短将广西原血吸虫病钉螺孳生地分成三类,针对不同螺区分类,对原螺区及毗邻地区采用不同的监测方案。结合血清学方法及粪便检查方法,抽样检查当地居地、原血吸虫病人及流动人口的监测检查工作,对监测结果进行考核。结果近十年来,广西发现5处残存螺点,分别位于玉林、靖西、宜州、横县等地,其中隶属南宁市辖区的横县发现残存钉螺2处。广西未发现本地血吸虫病人,流动人口监测过程中发现输入性病例23例,病人分别来自湖北、湖南、江西和安徽4省,除2例为女性外,其余均为男性。职业则以干部、商人、民工(农民)、学生及武警新兵为主。结论广西虽然保持阻断传播标准的成果,但由于不断新发现残存钉螺及输入性血吸虫病例,广西仍然面临血吸虫病的威胁。 Objective To explore the distribution characteristics of surviving snails newly discovered in Guangxi in recent ten years and the status of schistosomiasis infection among floating population so as to provide a scientific basis for the prevention and control of schistosomiasis. Methods According to the length of the surviving snail, we classified the snail habitat of the original schistosomiasis in Guangxi into three categories. According to the classification of different snail zones, different monitoring schemes were applied to the original snail zone and the adjacent area. Combined with serological methods and stool examination methods, sampling and checking the monitoring and checking work of the locality, the original schistosomiasis patients and the floating population, and examining the monitoring results. Results In the past ten years, five remaining snails were found in Guangxi, which were located in Yulin, Jingxi, Yizhou and Hengxian, respectively. Two of the remaining snails were found in Hengxian, a suburb of Nanning. In Guangxi, 23 cases of imported cases of schistosomiasis were not found. During the monitoring of floating population, 23 cases of imported cases were found. The patients were from Hubei, Hunan, Jiangxi and Anhui Provinces, respectively. Except for 2 cases, women were male. Occupation is cadres, businessmen, migrant workers (farmers), students and recruits mainly armed police. Conclusion Despite the achievements of Guangxi in blocking the transmission standard, Guangxi still faces the threat of schistosomiasis due to the continuous discovery of the remaining cases of snails and imported schistosomiasis.
