Bolivia showed consistent and statistically significant growth in the HIV incidence rate, with an increase of 83.8% over the decade analyzed (R<jats:sup>2<\/jats:sup>\u202f=\u202f0.67; <jats:italic>p<\/jats:italic>\u202f=\u202f0.0022). On the other hand, Guyana, although still among the countries with the highest incidence rates, showed a significant reduction of 31.6%. Suriname remained one of the countries with the highest rates throughout the period, exceeding 100 cases per 100,000 inhabitants in certain years. Spatial analysis revealed considerable disparities, particularly in border areas, where there is a higher concentration of cases, indicating the need for targeted public policies and shared surveillance efforts. Countries such as Peru, Colombia, and Paraguay also showed a growing trend, while Argentina, Uruguay, and Venezuela showed a decline or stagnation, although in some cases this apparent stability may be linked to underreporting.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Some countries need to strengthen actions and services to monitor and break the chain of transmission, and implement public policies, as well as re-evaluate and ensure in countries with socio-economic and political crisis, in order to transform this aggravating panorama in Latin and South
