【摘要】：目的分析广州口岸近年输入性登革热病例的流行病学情况,为国内登革热疫情的溯源和制定有效的预防控制措施提供依据。方法对2009-2015年经广州口岸入境、疑似登革热病例进行流行病学调查和登革病毒的实验室核酸检测,用描述性流行病学方法分析其流行特征和流行因素。结果 2009-2015年,使用实时荧光RT-PCR共检出输入性登革热病例152例,近3年输入病例逐步升高。89.5%病例来自亚洲,其中东南亚占87.5%,主要来源于泰国、越南、马来西亚、印度尼西亚、缅甸和新加坡等地。输入性登革热病例主要集中在21~40岁,男性占77%。全年均有输入性病例报告,其中第三季度和第四季度是高峰期,10月份输入性病例最多。结论东南亚地区的入境人员已成为广东省输入性登革热病例的重点人群。广东口岸地区面临输入性登革热的威胁,出入境检验检疫机构应及时掌握国内外疫情信息,加强口岸检疫查验、疾病监测,一旦发现疫情,及时采取有效的控制措施,防止输入性登革热造成本地疫情的爆发。
[Abstract]:Objective to analyze the epidemiological situation of imported dengue fever cases at Guangzhou Port in recent years, and to provide a basis for tracing the source of dengue fever epidemic in China and making effective preventive and control measures. Epidemiological investigation and laboratory nucleic acid detection of dengue virus were carried out in suspected cases of dengue fever. The epidemiological characteristics and epidemic factors of dengue virus were analyzed by descriptive epidemiological method. A total of 152 cases of imported dengue fever were detected by real-time fluorescent RT-PCR. In the last three years, the number of imported cases increased gradually. 89.5% of the cases were from Asia, of which 87.5% were from Southeast Asia, mainly from Thailand, Vietnam, Malaysia, Indonesia, Myanmar, Singapore and other places. Imported dengue fever cases are mainly concentrated in 21 to 40 years of age, and 77% of them are males. There are imported cases reported throughout the year. Among them, the third quarter and the 4th quarter were the peak periods for imported dengue fever cases in October. Conclusion the immigration population from Southeast Asia has become a key population of imported dengue fever cases in Guangdong Province, where port areas face the threat of imported dengue fever. The entry and exit inspection and quarantine institutions should grasp the information of the epidemic situation at home and abroad in time, strengthen the quarantine inspection at the port, monitor the disease, and take effective control measures to prevent the local outbreak caused by imported dengue fever once the epidemic situation is discovered.
