目的分析广东省佛山市禅城区2012年登革热暴发疫情流行病学特征和处置情况,为有效控制登革热疫情提供科学依据.方法采用流行病学方法对疫情数据,相关的现场调查和蚊媒调查资料等进行统计与分析.结果 2012年9-11月,佛山市禅城区登革I型病毒引起的登革热暴发疫情,共报告登革热病例239例,罹患率为21.68/10万,无重症及死亡病例.9月份发病数急骤上升,9-10月共发病192例,占总病例数80.23％,是发病的高峰时间,至11月下旬发病数明显下降,流行基本停息.各年龄组均有发病,经趋势检验,随着年龄增加罹患率上升,差异有统计学意义(x2趋势=34.89,P＜0.01).职业以商业服务、离休人员、工人居多,占病例总数的69.46％;17.15％的病例具有家庭聚集性(x2=2 402 734.60,P＜0.01).流行期间,蚊媒密度高峰后约10 d出现一波登革热发病高峰,截至11月中旬,布雷图指数并未降至＜5的安全线以下,导致发病数无明显下降.结论该次登革热发病水平高、持续时间长与蚊媒密度居高不下相关,对登革热流行的最有效控制关键在于迅速降低伊蚊密度.

Objective To analyze the epidemiological characteristics and disposition of a dengue outbreak in Chancheng District of Foshan in 2012,so as to provide scientific basis for effective control of dengue fever.Methods Epidemic data,the data from field investigation and mosquito survey were statistically analyzed.Results A total of 239 cases of dengue patients were reported in the outbreak from September to November 2012,with a incidence rate of 21.68/100 000.No severe or fatal disease was reported.The pathogen of this outbreak was dengue virus type I.The number of patients rose sharply from September,reaching 192 cases (80.23％)during the peak period of September and October,and then decreased in late November.There were cases reported in each age group,and the incidence rose with the increasing age by trend test (x2rend=34.89,P＜0.01).The dengue mainly occurred in commercial service staff,retiree and workers,accounting for 69.46％.About 17％ of cases showed family clustering (x2=2 402 734.60,P＜0.01).During the epidemic period,a peak of dengue cases always happened 10 days later after the mosquito density peak.By the middle ten days of November,Breteau Index didn't decrease below the safety line(＜5),so the incidence didn't decrease obviously.Conclusions The dengue outbreak lasted for a long time and affected a wide range,which may attribute to sustained high mosquito density.The key to effective control of dengue epidemic is to quickly decrease Aedes density.
