目的分析湖北省2009年国家级血吸虫病疫情监测点疫情变化,了解湖北省血吸虫病流行现状,为制定血吸虫病防治对策提供科学依据。方法根据《全国血吸虫病监测方案》的要求,16个监测点开展人群及家畜病情、螺情和相关因素调查,采用SPSS12.0软件统计分析监测结果。结果湖北省16个监测点居民感染率为1.03%,耕牛感染率为1.98%,活螺平均密度为0.2934只/0.11m2,感染螺平均密度为0.00041只/0.11m2,钉螺感染率为0.139%。各项疫情指标较前4年有所下降。结论监测点人畜感染率呈现持续下降,但部分监测村钉螺感染率仍较高,因此,应加强钉螺控制措施,提高药物灭螺质量,防止疫情反弹。
Objective To analyze the epidemic situation of national schistosomiasis surveillance spots in 2009 in Hubei Province, understand the current situation of schistosomiasis prevalence in Hubei Province, and provide a scientific basis for the development of schistosomiasis control strategies. Methods According to the requirements of “National Schistosomiasis Surveillance Program”, 16 monitoring sites were surveyed for the prevalence of disease, snail and related factors, and SPSS 12.0 software was used to analyze the monitoring results. Results The infection rate of cattle in 16 monitoring points in Hubei Province was 1.03%, the rate of cattle was 1.98%, the average density of live snails was 0.2934 /0.11m2, the average density of infected snails was 0.00041 /0.11m2, and the infection rate of snails was 0.139% . The epidemic index decreased from the previous 4 years. Conclusion The infection rate of human and animal in the monitoring sites showed a continuous decline, but the infection rate of some snails in some monitoring villages was still high. Therefore, snail control measures should be strengthened to improve the quality of drug snail and prevent the epidemic from rebounding.
