目的:分析近5年福州市登革热监测结果,为福州市登革热流行趋势的预测、预警和制定防治对策、措施提供科学依据。方法:对2004~2008年布雷图指数、容器指数和房屋指数等进行综合分析,采用酶联免疫法(ELISA法)对监测点正常人群的登革热IgG抗体水平和发热病人的IgG和IgM进行检测。结果:04年福州市出现登革热暴发,发热病人血清抗体IgG和IgM的阳性率均为28.49%(94/330),在05~08年正常人群血清IgG和监测点发热病人的IgM和IgG抗体阳性率均为0%。年均布雷图指数均超过10,分别为20.07、15.69、26.96、12.22、20.85。05~08年均有病例报告,且经流行病学调查系境外感染。结论:布雷图指数相对较高,一旦有传染源输入,极可能导致登革热流行,必须引起高度警惕。
OBJECTIVE: To analyze the monitoring results of dengue fever in Fuzhou in recent 5 years to provide scientific evidence for the prediction and early warning of dengue fever epidemic in Fuzhou and the formulation of prevention and control measures. Methods: The Brettizer index, container index and housing index were comprehensively analyzed from 2004 to 2008. The levels of dengue IgG antibody and IgG and IgM in the normal population were detected by enzyme-linked immunosorbent assay (ELISA). Results: The positive rates of serum IgG and IgM in patients with fever in 2004 were 28.49% (94/330) in the outbreak of dengue fever in Fuzhou City. The serum IgM and IgG antibodies in the normal population and the fever in the monitoring area from 2005 to 2008 were positive Rate is 0%. The average annual Bretton Woods index was more than 10, were 20.07, 15.69, 26.96, 12.22, 20.85. 05 ~ 08 each case report, and the epidemiological survey of foreign infections. Conclusion: The Brettillt index is relatively high. In the event of a source of infection, it is highly likely to cause dengue fever and must be highly vigilant.
