Sexually transmitted diseases in children and adolescents.

Sexually transmitted diseases have an impact on children's health at three times in their development: during pregnancy or delivery (through maternal-neonatal transmission), during prepubertal childhood (through sexual transmission), and during adolescence (through sexual transmission). These phases must be considered distinctly by the physician, since not only the type of infection but also the management and long-term implications of the disease vary with the time period in which it was acquired.
