AIDS and HIV infection in Brazil: a multifaceted epidemic

摘要

The HIV/AIDS epidemic is a dynamic unstable global phenomenon, constituting a veritable mosaic of regional sub-epidemics. As a consequence of the deep inequalities that exist in Brazilian society, the spread of HIV infection has revealed an epidemic of multiple dimensions undergoing extensive epidemiological transformations. Initially restricted to large urban centers and markedly masculine, the HIV/AIDS epidemic is currently characterized by heterosexualization, feminization, interiorization and pauperization. The evolution of the profile of AIDS in Brazil is above all due to the geographical diffusion of the disease from large urban centers towards medium and small municipalities in the interior, to the increase in heterosexual transmission and the persistent growth of cases among injecting drug users. The increase in transmission through heterosexual contact has resulted in substantial growth of cases among women, which has been pointed out as the most important characteristic of the epidemic's current dynamic in Brazil.
