Data were aggregated into 133 Intermediate Geographic Regions (IGRs). IGRs without a confirmed case during the studied period were excluded. A composite risk score was calculated for each IGR by combining (i) transmission duration (months with reported cases per year, score 0\u201312) and (ii) disease burden, based on national quartiles of monthly incidence and mortality (score 1\u20134). Annual scores were summed to produce risk maps for each arbovirus. High-risk IGRs (defined as the top quartile of composite score) were overlaid with popular tourist destinations to create an intuitive visual guide.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>We analysed 4.35 million dengue, 294\u2009921 chikungunya, and 2312 YF cases, resulting in 7846, 565, and 794 deaths, respectively. Dengue affected all IGRs, with high-risk IGRs in the Midwest, including the Pantanal. Chikungunya was also identified in all IGRs, with high-risk IGRs in the Northeast, overlapping with popular beaches such as Recife. YF was identified in 38.3% of IGRs, notably in the Southeast, including S\u00e3o Paulo state.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Arboviruses pose a diverse risk across Brazil.
