Abstract
Areas of intense migratory flow and industrial expansion present greater vulnerability to sexually transmitted infections, fostering their spread along commercial routes. Against this backdrop, this study analyzed the temporal trend and epidemiological profile of HIV in municipalities of Mato Grosso do Sul located along the Bioceanic Route (2010–2023). Specifically, temporal analyses of HIV rates were performed using data from the Notifiable Diseases Information System and the Brazilian Institute of Geography and Statistics. Additionally, we evaluated sociodemographic profiles and modes of transmission. Our results indicated an increase in HIV rates in Bataguassu, Guia Lopes da Laguna, Nioaque, Ribas do Rio Pardo, Santa Rita do Pardo, and Sidrolândia. In contrast, municipalities such as Campo Grande, Jardim, and Três Lagoas exhibited recent declining trends, possibly associated with the expansion of pre-exposure prophylaxis. Further analysis revealed that most cases occurred among males, with median ages ranging from 30 to 41 years, and a higher frequency of individuals who self-identified as brown in ethnicity. The most common probable mode of transmission was male-to-male sexual contact. These findings highlight the interiorization of the epidemic within the state and reinforce the need for combined prevention policies tailored to the context of commercial routes.
