Potential geographic displacement of Chagas disease vectors under climate change.

ABSTRACT: Climate change is projected to profoundly alter global biodiversity with significant implications for vector-borne disease dynamics. In tropical regions, rising temperatures and shifting precipitation patterns influence the distribution and behaviour of insect disease vectors, thereby affecting disease transmission cycles. Chagas disease, caused by the Trypanosoma cruzi and transmitted by triatomine bugs, is a major public health concern in Latin America. Brazil is particularly vulnerable to climate-driven vector redistribution due to its vast land area, diverse ecosystems and rapid land-use changes. Using ecological niche modelling and 11,640 unique occurrence records, we assessed the potential geographic displacement of 55 triatomine species under two climate scenarios: a moderate warmin
