目的分析2005-2015年云南省楚雄市省级血吸虫病监测点疫情变化态势,为制定全市血吸虫病防治策略提供科学依据。方法按照《云南省血吸虫病监测点监测方案》,每年在监测点开展病情、螺情及相关因素监测,并对11年的病情和螺情指标进行分析。结果 2005-2015年未发现本地新感染和输入性血吸虫病患者、病畜,累计查出钉螺面积28.25 hm~2,与2005年相比,2015年钉螺面积、活螺平均密度和有螺框出现率分别下降87.70%、84.74%和83.67%,无感染性钉螺。结论楚雄市血吸虫病监测点疫情稳定,但仍存在输入性传染源可能,下一步应加强螺情监测的质量控制和外来传染源防控工作,防止疫情反弹。
Objective To analyze the epidemic situation of schistosomiasis surveillance spots at provincial level in Chuxiong City, Yunnan Province from 2005 to 2015, and provide a scientific basis for the prevention and control of schistosomiasis in the city. Methods According to the monitoring plan for schistosomiasis surveillance in Yunnan Province, the condition, snail and related factors were monitored at monitoring sites every year, and the 11 years of illness and snail indicators were analyzed. Results From 2005 to 2015, no newly diagnosed imported and imported schistosomiasis patients and sick animals were found. The area of oncomelania snails was 28.25 hm ~ 2. Compared with 2005, the area of snails, the average density of live snails and the screw frame appeared Rate decreased 87.70%, 84.74% and 83.67%, non-infected snails. Conclusion The epidemic situation of schistosomiasis surveillance in Chuxiong is stable, but there is still the possibility of imported sources of infection. The next step should be to strengthen the quality control of snail surveillance and the prevention and control of external sources of infection, so as to prevent the epidemic from rebounding.
