2000～2004年湖北省血吸虫病监测点疫情分析

Analysis of Endemic Situation of the Surveillance Sites of Schistosomiasis in Hubei Province from 2000 to 2004

目的分析湖北省血吸虫病监测点5年来的疫情变化规律,为今后防治规划提供科学依据。方法按照《全国血吸虫病疫情监测点方案,》选择4个血吸虫病流行村作为监测点,并对其疫情进行流行病学监测。结果范渊村、挖沟村和新湖村2004年居民感染率比2000年分别下降了2.84%、62.98%和24.14%,西寺台村2004年居民感染率比2000年上升了30.84%;4个监测村的螺情仍未得到有效控制;各监测村耕牛感染率年间高低不一,仍维持在较高水平。结论现有防治措施在疫情控制上有一定效果,但要长期坚持,并需进一步加强完善监测工作方法,制订更科学、合理、有效的血吸虫病监测体系。

Objective To analysis the trends of endemic situation among 4 surveillance sites in Hubei province from 2000 to 2004 for making the strategies to control schistosomiasis. Methods According to the design of the national surveillance sites,four villages with schistosomiasis in Hubei province were selected for the study,and their epidemiological situation were observed between 2000 and 2004. Results Infection rates in residents of Fanyuan village, Wagou village and Xinhu village in 2004 dropped by 2.84%, 62.98%and 24.14% compared with those in 2000, respectively. But infection rates in residents of Xisitai village in 2004 rose 30.84% compared with those in 2000. Snarl was not well controlled in four villages and the infection rate of cattle was fluctuated yearly and maintained at a high level. Conclusion Current control strategies have some effects on control of morbidity. However, these control measures should last for longer time and the protocol of surveillance on schistosomiasis should be improved. A more scientific, more reasonable, and more effective surveillance system should be established for the control of schistosomiasis.
