Abstract

Dengue disease is a febrile viral disease that can be found in the tropical regions of the world. This disease is transmitted to human by the bites of infected Aedes Aegypti mosquitoes. It has increased in both incidence and distribution over the past 40 years. In each year, it is estimated that there are 20 million cases of dengue infection, around 24,000 deaths due to this disease. The data of dengue patients in Thailand indicates that the age structure of the population plays a role in the transmission of this disease. The effects of age structure and tourists on the transmission of dengue virus are the focus of this study. The effects are determined through a mathematical formulation of the transmission cycle.
