目的掌握我国血吸虫病流行变化趋势与规律,为2009年血吸虫感染高危地区提供预警信息。方法收集2009年80个国家级监测点及36个综合防治试点钉螺解剖数据进行预警分析,并结合2007~2008年监测点和综合防治试点人群、家畜病情资料进行比较。结果2009年感染性钉螺与2007~2008年分布基本一致,主要分布于江西省的鄱阳湖西南岸疫区以及湖南、湖北省的洞庭湖及长江沿岸的部分疫区。2008年人群感染率为0.67%,较2007年的0.92%有所下降,其中湖南、湖北及江西3省仍有大部分疫区村人群感染率>1%。2008年家畜感染率为1.62%,较2007年的2.90%有所下降,其中湖南、湖北及江西3省仍有部分疫区村家畜感染率>3%。结论鄱阳湖西南岸以及洞庭湖和长江沿岸的部分疫区感染螺分布集中,人群和家畜感染率总体呈下降趋势,但湖南、湖北及江西3省部分疫区疫情仍处于较高水平。
Objective To understand the trend and regularity of schistosomiasis prevalence in China and provide early warning information for the high risk areas of schistosomiasis infection in 2009. Methods Anatomical data of 80 national surveillance sites and 36 comprehensive prevention and cure snails collected in 2009 were collected for early warning analysis. Based on the monitoring points from 2007 to 2008 and comprehensive prevention and control pilot populations, the data of domestic animal diseases were compared. Results In 2009, Incontine snail was basically the same as the distribution in 2007-2008. It was mainly distributed in the epidemic area of the southwestern Poyang Lake in Jiangxi Province, Dongting Lake in Hubei Province and some affected areas along the Yangtze River. In 2008, the population infection rate was 0.67%, down from 0.92% in 2007, of which, most of the affected areas in Hunan, Hubei and Jiangxi provinces still had> 1% infection rates. In 2008, the infection rate of livestock was 1.62%, down from 2.90% in 2007. Among them, the infection rate of livestock in some affected areas in Hunan, Hubei and Jiangxi provinces was still> 3%. Conclusion The prevalence of infection in some epidemic areas on the southwestern coast of Poyang Lake, Dongting Lake and the Yangtze River is concentrated, and the population and livestock infection rate generally shows a decreasing trend. However, the epidemic situation in some epidemic areas in Hunan, Hubei and Jiangxi provinces is still at a high level.
