This study seeks to identify and reflect on medical strategies used to ensure the systematic use of condoms for the effectiveness of AIDS prevention, in particular, when patients are involved in serodiscordant marital relationship in that only one of the partners is HIV positive. As analytical tools we used the concepts of thinking styles of epistemology (Fleck), the training process (Good), and therapeutics (Sayd, Camargo Jr. and Almeida). Among the findings of the research stood out an invisibility of the serodiscordant couples, for what turns out to be really important is adherence to treatment, which coincides with adherence to medication (ART).
