AIDS, Acquired Immunodeficiency Syndrome, is a disease that arose in the XVth century and had a great impact on contemporary society. The earliest records of human contamination with the HIV virus were in mid-west Africa, at the beginning of the last century. However, AIDS began to spread around the globe between the late 20 and early 70 years. The first record in Brazil occurred in the city of São Paulo, in 80. At that time, most of the infected included men who had sex with other men, ie, homosexuals and bisexual men. In 1982, the Ministry of Health in Brazil launched the National AIDS Control Program, with the goal of dealing with the growing number of cases and avoiding a possible AIDS epidemic. Today, the Brazilian AIDS program is considered one of the most successful in the world. One of the main points of this policy is the universal and free distribution of medicines antiretroviral pelo SUS – Sistema Único de Saúde. Atualmente, o Brasil vem registrando quedas dramáticas em mortes pela AIDS.
