Brazil holds approximately 1/3 of population living infected with AIDS(acquired immunodeficiency syndrome) in Central and South Americas, and it wasalso the first developing country to implement a large-scale control andintervention program against AIDS epidemic. In this scenario, we investigatethe temporal evolution and current status of the AIDS epidemic in Brazil.Specifically, we analyze records of annual absolute frequency of cases for morethan 5000 cities for the first 33 years of the infection in Brazil. We foundthat (i) the annual absolute frequencies exhibit a logistic-type growth with anexponential regime in the first few years of the AIDS spreading; (ii) theactual reproduction number decaying as a power law; (iii) the distribution ofthe annual absolute frequencies among cities decays with a power law behavior;(iv) the annual absolute frequencies and the number of inhabitants have anallometric relationship; (v) the temporal evolution of the annual absolutefrequencies have different profile depending on the average annual absolutefrequencies in the cities. These findings yield a general quantitativedescription of the AIDS infection dynamics in Brazil since the beginning. Theyalso provide clues about the effectiveness of treatment and control programsagainst the infection, that has had a different impact depending on the numberof inhabitants of cities. In this framework, our results give insights into theoverall dynamics of AIDS epidemic, which may contribute to select empiricallyaccurate models.
