AIDS is a great human tragedy. Still, the only currently recognized cure for the disease is risk prevention. Unbelievable as it seems, these two facts have "opened up a great opportunity for social sciences to show their relevance and to test their models at both practical and theoretical levels" (Paicheler, 1992: 11). In particular, AIDS offers a unique opportunity to social scientists to observe responses to a new fatal disease as it occurs in different social settings. The research is interdisciplinary, incorporating basic premises from several fields including economics, sociology, social psychology, and development studies (Schoepf, 1992).
