DENGUE: A PROPOSAL FOR A CONCEPTUAL MODEL USING SYSTEMS DYNAMICS

Dengue is one of the main public health concerns in Brazil, responsible for significant social and economic impacts. The proliferation of Aedes aegypti, the disease’s vector, is intensified by environmental, social, and institutional factors, making its control a major challenge. Given this complexity, this study proposes a System Dynamics model that represents the interaction between key variables related to dengue. Based on a literature review, existing models were identified and a new model was developed, integrating previous approaches into a holistic view. Stock and flow diagrams, along with causal loops, were used to represent interactions between key variables. The study revealed emergent dynamics highlighting the increased criticality of variables such as population density.
