摘要
目的分析广州市近年来登革热疫情特点及流行规律,为制定预防控制措施提供依据。方法收集广州市2001-2010年登革热疫情资料,用描述性流行病学方法分析其流行特征和流行因素。结果 2001-2010年广州市共报告登革热病例2458例,每年均有本地感染病例和输入病例的报告,其中本地感染病例2366例,输入性病例92例。年发病率在0/10万～20.14/10万之间。疫情涉及12个区县,主要集中在荔湾区(26.24%)、越秀区(25.65%)、天河区(14.41)、白云区(12.00%)和番禺区(8.77%)。4-12月均有病例报告,其中5月份前为输入性为主的散发病例,6-12月为流行期,8-10月病例数占总病例数的88.12%,为发病高峰期。男女性别比为1.06∶1。各年龄组均有发病,但发病率以中壮年和老年人群居高。职业分布以家务及待业、工人和学生为主。病例输入地主要以印尼、越南、泰国等东南亚地区为主。暴发的疫情主要由登革病毒Ⅰ型引起。结论广州市登革热仍为输入或输入引起本地传播的传染病,至今仍无证据表明已成为地方性疾病。
Objective To analyze characteristics and risk factors of dengue fever in Guangzhou and provide evidence for followed actions of prevention and control. Methods Descriptive statistical methods were used on epidemiological data analysis of dengue fever between 2001 and 2010. Results A total of 2 458 local cases were reported as well as 92 external cases in Guangzhou between 2001 and 2010. The incidence was from 0 to 20.14 per 100 thousands annually. Cases were found in 12 districts but clustered in central areas of Guangzhou, and mainly from April to December. Epidemic sustained from June to December and peaked from August to October. The male / female ratio is 1∶1.06. Every age group had reported cases and the incidence grew high in the middle and the older age groups. Most cases were household workers, workers waiting for employment, ordinary workers and students. Imported cases from foreign countries were reported each year which were mainly imported from southeast Asia countries such as Indonesia, Vietnam, Thailand et al. Primary serotype of dengue virus caused endemic outbreaks was the type I strain. Conclusion The dengue fever epidemics of Guangzhou were closely related to imported cases or importer-induced endemic prevalence. However, the endemic nature of the disease had not been identified yet.
