Background & objectives: Dengue is considered one of the greatest public health challenges in the world, especially, for tropical and subtropical countries. Brazil highlights with considerable number of registers associated with this arbovirus, with emphasis on the state of Minas Gerais and its municipalities in regions such as the midwest. We aimed to evaluate the economic and epidemiological impact of dengue in the midwest region of minas Gerais, from SUS perspective.

Methods: Our study evaluated the epidemiological impact of dengue fever in the midwest region of Minas Gerais using data applied to Divinópolis city from SUS perspective between 2000 to 2015 considering SIH/SUS database (hospitalization registers) and 2007 to 2017 using the SINAN database (notification cases). We analyzed the number of notification registers and hospital services, as well as their costs, from a SUS perspective associated with this infection.

Results: There were 26,516 notifications associated with dengue, with 21,953 cases being confirmed by SEMUSA, with a median incidence of 211 cases/100,000 inhabitants of dengue notifications between 2007 and 2017. The southeast and southwest regions in the municipality are highlighted with high number of cases. Additionally, 160 hospitalizations were recorded with 33.79% in individuals between 15 and 34 years old and expenses of USD 53,737.21 for SUS between 2000 and 2015.

Interpretation & conclusion: Divinópolis is the reference (social and economic) municipality of the midwest region in Minas Gerais state. Our study is the first conducted involving a long period of follow up applied to dengue context in this locality, especially, including the costs associated with hospitalization services. We hope to contribute to the discussions regarding the coping strategies of the disease, considering the impact in its different regions, highlighting the need for continued efforts and initiatives aimed at combating the vector of this and other arboviruses such as Zika and chikungunya.
