Targeted HIV-prevention programs
Des, J., Padian, N., & Winkelstein, W. (1994). Targeted HIV-prevention programs. New England Journal of Medicine, 331(21), 1451-1453.
An effective program to prevent HIV infection must have both universal and targeted components. The universal component includes reducing HIV-related discrimination, removing commercial restrictions on the materials necessary for safer behavior, and providing information about the risk of HIV. The targeted component involves focusing the limited resources for intensive programs of behavioral change on situations in which the risk of HIV transmission is highest. Such a strategy would follow the dictum 'Warn widely and spend wisely.'
