title: Strategies to prevent HIV transmission to serodiscordant couples.
abstract: BACKGROUND
  The use antiretroviral reduces the sexual transmission of HIV, expanding interventions for serodiscordant couples.
  
  
  OBJECTIVE
  This article aims to review the use of antiretroviral and other prevention interventions among serodiscordant couples and to analyze its use in Brazil.
  
  
  METHODS
  A retrospective review was performed through the MEDLINE database and bases included in the Biblioteca Virtual em Saúde.
  
  
  RESULTS
  The articles recovered exhibit four main strategies: (1) condom; (2) reduction of risks in sexual practices; (3) use of antiretrovirals, particularly early initiation of antiretroviral therapy (TASP) and pre-exposure prophylaxis (PrEP); (4) risk reduction in reproduction.
  
  
  CONCLUSIONS
  TASP is highly effective in reducing sexual transmission, PrEP was tested in serodiscordant couples and both reduce the sexual transmission risk in different sexual practices, enabling individualized prevention strategies.
  
  
  CONCLUSIONS
  When used in combination, antiretrovirals and sexual practices with condoms offer greater efficacy than any single strategy. The combined use of new and old strategies allows us to build a prevention policy for all.
