Dengue fever is an acute mosquito-borne infectious disease caused by dengue virus and widely spread worldwide. Many factors, such as pathogens, vector organisms, climate, and social environment, affect its transmission and prevalence. The local dengue fever epidemic caused by imported cases in China shows a trend of increasing epidemic latitude and more widespread epidemic areas. However, the traditional monitoring and early warning models of dengue fever mainly focus on researching a single factor and a single area. Establishing a multi-factor forecast and early warning system is urgent to strengthen the early warning capability for the dengue fever epidemic. This paper mainly discusses the epidemic characteristics, the influencing factors, and the surveillance and early warning models of dengue fever in China to provide a reference for the effective prevention and control of dengue fever in China.
登革热是由登革病毒引起的、在全球范围广泛传播的急性蚊媒传染病，其传播和流行受病原体、病媒生物、气候和社会环境等多种因素影响。目前，由输入病例引起的本土登革热疫情在我国呈现流行纬度越来越高、流行区域越来越广的趋势。然而，传统的登革热疫情监测预警模型，大多集中于单一因素、单一地区的研究，因此，迫切需要建立多因素监测预警系统，以提高早期预警能力。本文主要对我国登革热的流行特征、流行的影响因素及监测预警模型相关研究进展进行综述，以期为我国登革热疫情的科学防控提供参考。.
