Mathematical model of dengue transmission in the early-age group

Dengue fever is a disease that occurs every year and this is always a big concern for the community when entering the rainy season. Based on data from the Ministry of Health of the Republic of Indonesia, the age group that is most susceptible to dengue is less than 15 years old. At the time of the COVID-19 pandemic, dengue fever has less attention from the public and the government even in 2020, there are 160,000 cases from January through March with 100 deaths. In this study, the author interested to construct a mathematical model for dengue transmission by involving the early-age group in the population. The analysis will begin by looking at the transmission process between vectors (Aedes aegypti mosquitoes) and humans, analyzing the equilibrium points, basic reproduction number and making interpretations. Based on the model with mathematical analysis, the disease will increase with two factors are the number of recruitments in susceptible in group A and infection rate. However, several factors will suppress the transmission such as the transition of children. © 2023 Author(s).
