[Sexually transmissible diseases in adolescence (author's transl)].

: Sexually transmissible diseases affect adolescents as well as the rest of the French population. It is difficult to estimate their frequency from official statistics since not all cases are reported. However, the recrudescence of these diseases is certain, with adolescents representing 10 to 50 0/00 of all cases. These diseases threaten the obstetrical and gynecologic future of adolescents and cost society a great deal of money. In the combat against them, prevention and public education are as important as early screening.
