Objective: To analyze the surveillance results of schistosomiasis and understand the transmission situation in Hubei Province in 2014.
Methods: According to the Scheme of Schistosomiasis Surveillance in Hubei Province (the 2009 edition), 207 endemic sites were selected, where the schistosome infections of residents and livestock, and the distribution of Oncomelania hupensis snails were investigated.
Results: In the 207 sites, there were 27 sites without positive results of the blood tests and 129 sites without positive results of the stool tests. The infection rates of residents and cattle were 0.17% and 0, respectively. The density of living snails was 0.339 3 snails/0.1m2, the rate of living snails was 10.12%, and the infection rate of snails was 0. The infection rate of residents in the inner embankment type was 0.22%, higher than the rates in the other types. In different age groups, the infection rate in the 50-59 years age group was higher than the rates in other age groups. The infection rates of residents in farmer and fisherman were higher than those in the other occupation groups. The infection rate of floating people was 0, and no acute schistosomiasis patients were found.
Conclusions: The endemic situation of schistosomiasis has decreased obviously in Hubei Province, and the whole province has achieved the criteria for transmission control of schistosomiasis.
[摘要]目的 分析2014年湖北省血吸虫病疫情监测资料, 掌握全省血吸虫病流行态势。方法 根据《湖北省血吸虫 病监测方案》 (2009年版) 的要求, 在全省13个市的63个血吸虫病流行县 (市、区) 共设立207个有代表性的监测点, 开展 人畜血吸虫病病情和螺情监测, 并对监测点内的防治措施落实情况进行调查。结果 2014年湖北省207个血吸虫病监 测点中, 27个监测点无血检阳性病例, 129个监测点无粪检阳性病例。居民血吸虫感染率为0.17%, 耕牛感染率为0, 活 螺平均密度为0.339 3只/0.1 m2, 有螺框出现率为10.12%, 钉螺感染率为0。不同流行类型中, 垸内型地区居民血吸虫感 染率最高, 为0.22%; 不同年龄组人群中, 50~岁年龄组居民血吸虫感染率最高, 为0.3%; 不同职业居民中, 农民和渔民 血吸虫感染率较高, 分别为0.21%和0.67%。2014年全部监测点内均未发现流动人口血吸虫感染病例, 未发生急性血吸 虫感染。结论 湖北血吸虫病疫情大幅下降, 全省血吸虫病各项疫情指标均已达到血吸虫病传播控制标准。.
