【摘要】 [目的 ]开展疫情监测和媒介调查 ,防止登革热暴发流行。 [方法 ]采集可疑病人双份血清、不明原因发热病人和健康人静脉血 ,以血凝抑制和免疫萤光法检测 Ig M和 Ig G;以房屋指数、容器指数和布雷图指数确定媒介种群密度。[结果 ]1999年原流行区发现可疑病人 3例 ,Ig G阳性 1例 ,患者系境外感染 ;福州、漳州不明原因发热 73例 ,Ig M和 Ig G抗体均为阴性 ;以免疫萤光法检测 1999年流行区健康人群血清 10 0份 ,Ig G阳性率为 17.0 % ,其它地区 2 5 0份均为阴性。11个县 (市、区 ) 38个媒介调查点仅捕获白纹伊蚊 ,其幼虫密度平均房屋指数 37.3% ,容器指数 4 5 .0 % ,布雷图指数78.9;沿海地区白纹伊蚊密度远较山区县为高。白纹伊蚊各类孳生环境多达 2 7种。[结论 ]登革热在福建沿海地区存在流行的危险性。

【Abstract】 Objective] To carry out surveillance of dengue fever and investigation of the vector for the disease control and prevention in Fujian, China. [Methods] The IgM or IgG were identified by immunofluorescence tests using serums from suspected patients, febrile patients and healthy people. The density of vector was investigated from July to September in 38 communities of 11 cities or counties.[Results] The IgG was positive in one of the three suspected patients from epidemic area in 1999, a traveler return from Thailand. Both IgG and IgM were negative in 73 febrile patients of unknown causes in Fuzhou and Zhangzhou. The IgG positive rate was 17% in 100 healthy people from epidemic region and 0% in 250 healthy people from non epidemic regions. Only Aedes albopictus (AA) were caught from 38 vector surveying sites in 11 counties. Of AA larvae density, the average house index was 37 3%, container index was 45 0% and Breteau index was 78 9. The density of AA was higher in coastal areas than in mountain areas. AA was found to breed in 27 different containers accumulating water.[Conclusion] There exists potential epidemic of dengue fever in Fujian coastal areas.
