摘要

The global burden of arboviral diseases, such as dengue, Zika, and chikungunya, has increased significantly in recent years, driven by various factors including climate change, rapid urbanization, increased global mobility, and vector resistance to conventional control measures. This review synthesizes current knowledge on the emergence and transboundary spread of these diseases, emphasizing the intricate relationship between environmental, biological, and socio-economic factors. A comprehensive analysis was conducted, incorporating data from a variety of sources including climate models, surveillance studies, and vector control programs. The results indicate that rising temperatures and altered precipitation patterns have expanded the range of key vectors such as Aedes aegypti and Aedes albopictus, the two principal mosquito species responsible for arbovirus transmission, facilitating the transmission of arboviruses in regions previously considered low-risk. Furthermore, urbanization has amplified the spread of these diseases, with densely populated areas providing optimal conditions for vector breeding. The review also highlights the growing concern of insecticide resistance, which complicates efforts to control vector populations. Emerging technologies, including genetic modification of vectors and innovative surveillance systems, show promise for enhancing control measures. The findings underscore the need for a coordinated, multidisciplinary approach to mitigate the impact of arboviral diseases and emphasize the importance of continued research in vector biology, climate dynamics, and public health interventions.
