三峡工程湖北段二期库区卫生清理及蓄水后人畜共患病监测

Faeces clearance and surveillance of zoonosis-borne diseases in Three Gorges reservoir area before and after the second sluicing in the Three Gorges Project

目的探讨三峡库区湖北段卫生清理过程中的经验和问题,掌握蓄水后库区病媒生物和人畜共患病的变化动态,分析蓄水后环境改变对库区人群健康的影响。方法依据长江三峡库底卫生清理技术规范,统计分析库区内人畜共患病发病情况。结果卫生清理工作符合国家标准规定要求,顺利通过验收,满足了蓄水的需要;蓄水后库区监测点肾综合征出血热、钩端螺旋体病和流行性乙型脑炎均为散发。结论三峡库区卫生清理有效地清除了库区污染源,蓄水后库区内未出现病媒生物异常及人畜共患病的流行暴发,至今尚未发现三峡库区蓄水对库区人群健康产生显著影响。

Objective To evaluate diseases prevention and control in the reservoir before the sluicing, and to understand the morbidity level and trend of zoonosis in the population in the Three Gorges Area after the sluicing. Methods The standard disinfection and vector control practises issued by China CDC, to analysis the data of zoonosis in Three Gorges area. Results After the clearance of waste out of the reservoir before the slucing, no outbreak of Epidemic Hemorrhagic Fever, leptospirosis and Encephalitis B is reported. Conclusion Waste clearance can protect the water from being polluted after the sluicing, no outbreak of zoonosis-borne diseases is reported, and no significant effect of environment change on the zoonnosis is found.
