Abstract: Both dengue fever (DF) and chikungunya fever (CHIKF) are important mosquito-borne viral diseases with global distribution, and these two diseases have relatively similar epidemiological and clinical features, with the main vectors of Aedes aegypti and Ae. albopictus. The local epidemic of DF occurred in China-Myanmar and China-Laos border areas of Yunnan province, China every year in 2013-2019, and it also occurred in China-Vietnam border area in 2019, while the local epidemic of CHIKF occurred in China-Myanmar border area for the first time in 2019. The imported cases of DF and CHIKF from Myanmar, Laos, Thailand, and/or Vietnam were the main cause of the local epidemic of these two diseases in Yunnan province. The special geographical location and ecological environment of Yunnan province are suitable for the breeding of the vector Aedes mosquitoes and the transmission of DF and CHIKF viruses. There are still high risks of re-epidemic or pandemic of DF and CHIKF in this region, with the possibility of endemic an severe cases of DF. At present, there is an urgent need to carry out in-depth research on the source of pathogens, the investigation of epidemic foci, clinical science, antibody level in population, and sustainable control of Aedes vectors, and meanwhile, control of cross-border spread, mosquito control, and joint prevention and control in China-Myanmar, China-Laos, and China-Vietnam border areas are the key prevention and control measures that need to be strengthened at present.

摘要: 登革热和基孔肯雅热均为全球性分布的重要蚊媒病毒病,二者具有较为相似的流行病学和临床特征,主要传播媒介均为埃及伊蚊和白纹伊蚊。2013-2019年位于云南省的中国-缅甸(中缅)、中国-老挝(中老)边境地区每年都发生登革热本地流行,2019年中国-越南(中越)边境地区也发生登革热本地流行,2019年中缅边境(瑞丽市)首次发生基孔肯雅热本地流行,来自缅甸、老挝、泰国和/或越南的输入性病例是引起云南省这2种蚊传疾病本地流行的主要原因。云南省特殊的地理位置和生态环境适于媒介伊蚊的孳生繁殖,也适于登革病毒和基孔肯雅病毒的传播,该地区仍然存在登革热和基孔肯雅热再次流行或大流行的风险,并有可能形成地方性流行以及引发登革热重症病例。当前急需开展病原体溯源、疫源地调查、临床学、人群抗体水平以及媒介伊蚊可持续控制的深入研究;同时,防范跨境传播,防蚊灭蚊以及中缅、中老、中越的双方边境地区联防联控是当前亟待加强的重点防控工作。
