摘要
目的掌握江苏省血吸虫病疫情动态,为制订防治策略和考核防治效果提供依据。方法按《全国血吸虫病监测方案》的方法,在全省8个国家级监测点开展血吸虫病疫情监测。结果2个监测点发现了粪检阳性者,常住居民总感染率为0.10%。5个监测点查到钉螺,其中4个监测点查到感染性钉螺,总的感染性螺平均密度为0.00224只/0.1m2。仅在1个监测点发现粪检阳性羊、未发现阳性牛,家畜总的感染率为0.90%。结论监测区疫情总体上较2005年和2006年有所下降,但局部地区感染性钉螺面积和密度仍较高、渔船民的感染率有所上升;今后仍需加大防治力度,进一步降低血吸虫病流行水平。
Objective The present study was conducted to research the dynamic endemic situation in Jiangsu, so as to provide evidence and basis for policy-making and evaluation of schistosomiasis control in Jiangsu province. Methods According to the National Scheme of Schistosomiasis Surveillance, the endemic situation of schistosomiasis was monitored in 8 national schistosomiasis surveillance sites in Jiangsu. Results Schistosomiasis patients were found positive in fecal examination in 2 surveillance sites, and the infection rate of permanent residents were 0.10%. Oneomelania snails were found at 5 surveillance sites, and in 4 of the 5 sites infectious oneomelania snails were found. The overall density of infectious oneomelania snails was 0.002 24/0.1m^2. At 1 site, sheep were found to be positive in fecal examination; positive cattle were not found; and the overall infection rate was 0.90% of the livestock. Conclusion Compared with the situations in 2005 and 2006, the endemic prevalence in the surveillance sites decreased in 2007. However, in some places the area and density of local infectious oneomelania snails were still high, and the the schistosomiasis infection rates of fishermen increased. Therefore, stronger control is necessary in the future to further reduce the prevalence of schistosomiasis.
