Shanghai has experienced multiple severe dengue fever outbreaks in recent years, which is a vector-borne viral disease spread by mosquitoes and poses a great challenge to the local public health. Studies show that the transmission patterns of dengue fever are complex and diverse, involving multiple factors, including climate change, urbanization process, and human activities.
