[AIDS prophylaxis: Analysis of a strategy]

This study draws attention to some of the problems encountered in developing strategiess for prophylaxis against AIDS. Some approaches have been reconsidered and amended--at least partially--although other potentially important problems remain, such as those arising from the most recent definition of the disease, now considered to be sexually transmitted, and those related with the attitudes of different target audiences of messages encouraging the use of prophylactic measures. This article attempts to highlight the practical consequences of certain theoretical claims about the disease and prophylactic measures.
