目的了解蓄水后三峡库区湖北省宜昌段自然疫源性疾病的动态变化,为及时制定卫生防病措施提供依据。方法连续收集2003-2015年监测点自然疫源性疾病发病资料、人群血清学和鼠类监测资料,进行综合分析。结果 2003-2015年三峡库区湖北省宜昌段报告钩端螺旋体病(钩体病)、疟疾、狂犬病各1例,未发现鼠疫、肾综合征出血热(HFRS)及其他自然疫源性疾病病例;HFRS和钩体病抗体人群血清阳性率分别为2.22%和14.12%;室内鼠密度先上升后下降,室外鼠类捕获率呈波动性下降趋势。鼠肾钩端螺旋体、鼠肺HFRS阳性率分别为3.49%和0.35%。结论尚未发现三峡库区湖北省宜昌段自然疫源性疾病对人群健康造成明显影响,但应继续开展监测。
Objective To understand the dynamic changes of natural foci of Yichang, Hubei Province in the Three Gorges Reservoir after impoundment, and to provide the basis for timely formulation of health and disease prevention measures. Methods The incidence data of natural foci of the epidemic-prone diseases at the monitoring points from 2003 to 2015, the population serological and rodent surveillance data were continuously collected for comprehensive analysis. Results One case of leptospirosis (leptospirosis), malaria and rabies was reported from Yichang section of Three Gorges Reservoir in Hubei Province from 2003 to 2015. No plague, hemorrhagic fever with renal syndrome (HFRS) and other natural foci were detected . The seroprevalence of HFRS and leptospirosis patients was 2.22% and 14.12% respectively. The indoor rat density increased first and then decreased, and the outdoor rat catch rate showed a decreasing trend. The positive rate of HFRS in mice was 3.49% and 0.35%, respectively. Conclusion The natural epidemic diseases in the Yichang Section of the Three Gorges Reservoir Area in Hubei Province have not been found to have a significant impact on the health of the population, but monitoring should be continued.
