摘要
目的掌握全国血吸虫病疫情监测点2002年的疫情。方法根据《全国血吸虫病疫情监测点方案》,对2002年全国21个疫情监测点的疫情进行监测,其中重度和轻度流行区各3个,中度流行区14个。结果(1)人群血吸虫病粪检阳性率最低为0.6%(江苏丹徒),最高17.72%(江西南昌),年龄和职业是影响感染水平的重要因素;当年共发生急性血吸虫病感染2例,新发现晚期血吸虫病1例;(2)各点耕牛感染率普遍较高,地区间差异较大(0～58.33%);(3)各监测点2002年均发现活螺,其中8个点的活螺框率超过40%,除上海金山、湖北蔡甸和四川丹棱外均发现感染性钉螺,其中湖南君山首次在垸内发现感染性钉螺。结论2002年全国监测点防治工作取得了一定的成效,但因存在疫情反复的因素,须进一步加强对各个监测点血吸虫病疫情的监测和控制工作。
Objective To review the endemic situation among twenty one national surveillance sites in 2002. Methods According to the design of national surveillance sites, surveillance of endemic situation of schistosomiasis was carried out on twenty one surveillance sites in 2002. There were 3 high endemic sites and 3 low endemic sites, and the others were all moderate endemic sites.Results (1) The infection rate of Schistosoma japonicum varied from 0.6 percent (Dantu) to 17.72 percent (Nanchang). Age and occupation were the main factors influencing the infection levels. Two acute cases and one advanced case were found. (2)The infection rates of cattle were still generally high, and the rates greatly varied far from each surveillance site (from 0 to 58.33%). (3) In 2002, living snails were found in each site, and the living rate of the snails in the quadrat were over 40% in eight surveillance sites. Infective snails were found in all sites except Jinshan、Caidian and Danling,and it is the first time infected snails were found in inner embankment in Junshan surveillance sites. Conclusion The control on schistosomiasis has reached some achievements. However, because of the fluctuation of the endemic situation, the surveillance should be enhanced.
