Abstract:

目的对广东和香港(粤港)地区2004-2006年报告的输入性登革热病例情况进行流行病学分析及比较.方法通过广东省登革热疫情监测报告系统收集广东省输入性登革热的流行资料,香港的资料由香港卫生署卫生防护中心提供;对收集到的两地资料进行描述性流行病学分析.结果 2004-2006年广东省报告输入性登革热病例数44例,香港报告93例;广东省病例的输入国主要是新加坡(13例)、印度尼西亚(9例)、柬埔寨(6例),香港病例的输入国主要是印度尼西亚(31例)、菲律宾(16例)、泰国(15例);两地发病高峰期均为7-9月,非高峰期香港的病例数高于广东省;两地病例的男女性别比:广东省1.2:1,香港1.1:1;广东省病例年龄从6～80岁,大部分为20～39岁(占63.6%,28/44),职业以商业及服务业、家务及待业为主(占40.9%,18/44);香港病例年龄从10～72岁,大部分为20～39岁(占58.1%,54/93),职业以商业及服务业、工人为主(占47.3%,44/93);广东省入境前发病的病例比入境后发病多(27:17),而香港入境前发病的病例比入境后发病少(35:57);两地病例从发病到诊断的平均时间间隔分别为7 d和9 d.结论造成粤港两地登革热输入的主要原因是旅游及商务人员在夏季与东南亚国家之间的频繁往来.

English Abstract:

Objective To analyze the epidemiological characteristics of imported cases of dengue fever in Guangdong province (GD) and in I-long Kong (HK) during 2004-2006 to provide evidence for further cooperation in the prevention and control programs on dengue fever in the two places.Methods Descriptive statistical analysis was performed on data obtained from dengue fever surveillance and reporting network in GD and from Centre for Health Protection,Department of Health,HK.Results Both from GD and HK 44 and 93 imported cases of Dengue fever were reported during 2004-2006.Most patients from GD acquired their infection from Singapore (13 cases),Indonesia (9 cases) or Cambodia (6 cases) while patients in HK mainly were imported from Indonesia (31 cases),the Philippines (16 cases) and Thailand (15 cases).The peak seasons of the two places were both from July to September.During the non-peak season period,the number of cases in Hong Kong was higher than that in Guangdong.Male/ female ratio was 1.2 : 1 in GD and 1.1 : 1 in HK.Age of patients in GD appeared to range from 6-80 years,with 63.6% (28/44) of them aged 20-39 years.40.9% (18/44) of the cases were engaged in business,services,housework or unemployed.Those cases in HK were between 10-72 years of age,with 63.6%(28/44) of them aged 20-39 years while 47.3%(44/93) of the patients were with the occupation of business,services and industry.More cases in GD had a onset of disease before entering the border (27 : 17) than the cases in HK (35 : 57).The average time interval between onset and diagnosis were 7 and 9 days for GD and HK respectively.Conclusion Frequent travel between Southeast Asia in summer among the working class appeared to be the main factor,causing imported cases of dengue fever in GDand HK.It is crucial to provide health education targeted at these high risk groups in order to prevent importation of dengue fever in the two areas.
