Dengue fever is the most serious mosquito-borne disease in China and around the world. There are great challenges in the prevention and control of this disease, which poses a great threat to public health and national biosecurity in China. There were significant increases in the number and spatial distribution of dengue cases in China in 2019, which has reached an unprecedented level. Specific and universally applicable strategies and measures for the prevention and control of this disease should be developed and implemented in accordance with local conditions. On the basis of the surveillance of the vector Aedes and cases, risk assessment and early warning should be performed with reference to meteorological data, environmental factors, and demographic data. Sustainable control strategies and measures should be adopted based on local conditions. This article analyzes the dengue epidemic situation in 2019 and discusses the challenges and strategies for its prevention and control in future China, in order to provide a scientific basis for precise prevention and control of dengue fever in various regions of China.
