Using land change data from MapBiomas (1985–2022), we assessed land cover shifts, including forest, deforestation, and urbanization, and their impact on Trypanosoma cruzi vectors. Urban growth has largely replaced mixed-use and forest areas, bringing some populations closer to remnants of the forest and increasing triatomine presence indoors. We documented 1,518 triatomine records, with ~ 50% testing positive for T. cruzi . Statistical models showed that deforestation and the remaining forest patches within neighborhoods are key factors influencing triatomine frequency. This urban expansion raises the risk of parasite transmission among vulnerable groups. To mitigate this, we recommend enhanced surveillance, control strategies, and health education in high-risk neighborhoods, aiming to reduce exposure and prevent disease transmission associated with deforestation and habitat changes.</p>
