Abstract
Dengue fever, a vector-borne disease spread by bites of infected female Aedes mosquitoes, has
spread globally with several outbreaks. Thus, understanding the life cycle of Aedes mosquitoes,
reproduction, transmission mechanisms, and weather variables is crucial for effective control of
mosquitoes and surveillance of dengue fever. This paper systematically presents a novel
stochastic agent-agent-based model implemented using GAMA 1.9.2 that simulates the trans-
mission dynamics of dengue virus and the life cycle of Aedes Aegypti mosquito in low-resource
environments in Dar es Salaam-Tanzania. The simulation results indicated that changing
weather parameters influenced the vector population dynamics. The vector population
increased gradually when weather conditions were favourable and vice versa. The simulation
results revealed a continuous dengue prevalence throughout the year, indicating a silent
spread of dengue. During the silent spread of dengue, it may be optimal to intervene in
mosquito production at the egg and larva stages and eradicate adult mosquitoes.
