Sexually transmitted diseases. Present problems-future prospects

The tools of molecular biology have brought us to a new level of understanding of the epidemiology and pathophysiology of sexually transmitted diseases, which has been augmented and concentrated by the challenge of HIV/AIDS. We enter the next millennium with an unprecedented knowledge of these infections, but lacking the resources and drive to apply this broadly, especially where most needed in the areas of socioeconomic deprivation. We may develop cures or vaccines for complex viral infections, but for whom? Eventually, the knowledge will flow and disseminate, but will practice change?
