摘要:

目的 了解云南省输入性登革热流行特征,为登革热防控措施的制订提供科学依据。方法 从国家传染病监测网络报告系统,收集和整理2004-2014年云南省登革热输入病例资料,采用描述性流行病学方法进行分析,登革热病毒血清型检测采用RT?PCR方法鉴定。结果 云南省2004-2014年累计报告输入性登革热病例629例,占全省登革热病例总数的28.70%(629/2 192);输入病例主要分布于德宏州(341例)、西双版纳州(159例)和昆明市(108例);各月均有输入病例报告,其中8-11月占输入病例总数的85.37%(537/629);629例输入病例中,男性419例,女性210例;以21~50岁年龄组为主(70.91%);职业分布以商业服务者为主(26.23%),其次是农民(21.30%)和学生(11.45%)。病例主要由缅甸(403例)和老挝(132例)输入;输入病例4种登革热病毒血清型均有发现,其中老挝输入病例以登革热病毒血清3型为主,缅甸以登革热病毒血清1型为主。结论 云南省2004-2014年输入病例数有逐年增加趋势,输入病例主要发生在与缅甸和老挝相邻的滇西南边境地区,云南省应重点加强边境地区输入病例监测,以防止输入病例引起的本地感染病例或暴发。

Abstract:

Objective To understand the epidemiological characteristics of imported dengue cases in Yunnan during 2004-2014, and provide the scientific information for the effective strategies of dengue control and prevention. Methods The data of imported dengue cases were collected from China Information System for Diseases Control and Prevention during 2004 to 2014. A database was established to analyze the epidemiological characteristics with method of descriptive epidemiology; dengue serotype was detected by RT-PCR.Results From 2004 to 2014, a total of imported cases were 629 (629/2 192, 28.70%) in Yunnan; The imported cases of dengue were mainly reported in Dehong Prefecture (341 cases), Xishuangbanna Prefecture (159 cases) and Kunming city (108 cases); The cases were reported every month, but 85.37% (537/629) of the cases were imported between August and November. Male cases were much more than female, 419 and 210 cases respectively. The occupations of cases mainly were business service people (165 cases), farmers (134 cases) and students (72 cases). Most cases were imported from Myanmar (403 cases) and Laos (132 cases). Four (4) dengue serotypes were found from imported cases; of those DEN-3 was the major type in those from Laos, and DEN-1 in those from Myanmar. Conclusion The imported dengue cases have been on rise in Yunnan, and their major concerns are the border areas with Laos and Myanmar. The above results suggested that colloborative efforts from various agencies should be strengthened to monitor border imported dengue cases in case of dengue outbreak.
