Abstract: Dengue fever is an acute infectious disease caused by the bite of mosquitoes of Aedes albopictus or Aedes aegypti that carries dengue virus, and it is widely prevalent in the tropical and subtropical areas. In Yunnan, the first case of dengue fever was reported in 1975, and in 2013, the first outbreak triggered by imported cases occurred in the China-Myanmar and China-Laos border areas. By summarizing and analyzing the research findings pertinent to the distribution characteristics of the reported dengue fever cases, etiological features, and transmission vectors in Yunnan Province in recent years, this paper has basically clarified the epidemiological characteristics of dengue fever in the province, thereby providing a reference for prevention and control of dengue fever in the future in Yunnan.
