Abstract
The paper reviews factors that may have contributed to the changing epidemiology of dengue in Southeast Asia as well as challenges of disease prevention. It discusses a regional approach to active dengue virus surveillance, focusing on urban areas where the viruses are maintained. Since most of the countries in the region are developing economies, this could provide a solution to limited financial resources. A regional approach would also result in greater likelihood of success in disease prevention as high volumes of human travel contribute to the geographical spread of dengue viruses
