目的分析广州市白云区2014年登革热流行病学特征,为制定登革热防控措施提供科学依据。方法收集白云区2014年登革热病人资料和蚊媒监测资料,采用描述性流行病学方法分析其流行特征,采集病例血清进行登革热病原学检测,使用布雷图指数及标准间指数、成蚊密度进行蚊媒密度调查分析。结果2014年白云区共报告登革热11 842例,其中男性5 911例,女性5 931例;发病高峰集中在8-10月份,11月份开始回落;各街镇均有发病病例;发病主要集中在青壮年;职业分布以家务及待业人员最多。按临床分型,普通型登革热11 245例,重症登革热51例,普通型登革热与重症登革热多数临床表现差异有统计学意义(P<0.05)。平均布雷图指数4.69,4-9月份布雷图指数在5以上;平均诱蚊诱卵器指数13.18%,8-10月份诱蚊诱卵器指数均在5以上。结论 2014年白云区登革热呈多点高强度流行态势;有必要加强登革热的监测和防蚊、灭蚊工作,防止登革热疫情的持续暴发。
Objective To analyze the epidemiological characteristics of dengue in Baiyun District of Guangzhou in 2014 and provide a scientific basis for dengue prevention and control measures. Methods The data of dengue fever and mosquito media monitoring in Baiyun District in 2014 were collected. Descriptive epidemiology was used to analyze the epidemiological characteristics of dengue fever. Serum samples were collected for pathogenicity detection of dengue fever. Breeding index and standard deviation index Media density analysis. Results A total of 11 842 cases of dengue fever were reported in Baiyun District in 2014, including 5 911 males and 5 931 females. The peak incidence peaked at 8-10 months and began to decline in November. The incidence of dengue was in all towns and townships. Zhuang years; occupation distribution to the most domestic workers and unemployed. According to the clinical classification, there were 11,255 cases of common dengue fever and 51 cases of severe dengue fever. The clinical manifestations of common dengue fever and severe dengue fever were statistically significant (P <0.05). The average Brettip index was 4.69, the BrettiAp index was above 5 in April-September, the average mosquito-respired lacquer index was 13.18%, and the mosquito-evacuated index was above 5 in August-October. Conclusion In 2014, dengue fever in Baiyun District showed a multi-point, high-intensity epidemic situation. It is necessary to strengthen the monitoring of dengue fever and prevention and control of mosquitoes and mosquitoes and prevent the outbreak of Dengue Fever.
