The HIV/AIDS epidemic has been simplistically interpreted as a phenomenon restricted to risk groups that are socially and spatially circumscribed. However, epidemic trends in recent years have demonstrated the need to employ open diffusion models that emphasize social interaction as a means of spread of HIV. This study is a spatial analysis of the AIDS epidemic in Brazil, which sought to incorporate variables reflecting economic and demographic events into a system for processing geographically referenced health information. Findings indicate that metropolises and regional urban centers, mainly those in the Southeast, play an important role in the spread of the epidemic, not only because of their population density but also because they are centers of trade and social interaction. In smaller cities located in the state of São Paulo, a large number of AIDS cases among injecting drug users are concentrated, revealing the routes and centers of cocaine use.
艾滋病毒/艾滋病疫情一直被简单地解释为一种仅限于在社会和空间上受到限制的风险群体的现象。然而，近年来的疫情趋势表明，需要采用强调社会互动作为艾滋病毒传播途径的开放扩散模型。本研究是对巴西艾滋病疫情的空间分析，旨在将反映经济和人口事件的变量纳入一个处理地理参考健康信息的系统。研究结果表明，大都市和区域城市中心，主要是东南部的那些城市，在疫情传播中发挥着重要作用，这不仅是因为它们的人口密度，还因为它们是贸易和社会互动的中心。在圣保罗州的较小城市中，注射吸毒者中的大量艾滋病病例集中在一起，揭示了可卡因使用的途径和中心。
