Introduction to Sexually Transmitted Infections

According to the Centers for Disease Control and Prevention (CDC), sexually transmitted infections (STIs) are a group of contagious diseases most commonly transmitted “from person to person by close, intimate contact.” Although most of this contact has traditionally been sexual intercourse, many categories of sexual practices permit transmission from “person to person.” Vertical transmission from mother to newborn is also possible. The means of transmission unite these diseases—not etiologies, symptoms, or clinical consequences. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
