New advances and challenges in sexually transmitted infections in the adolescent population. Document of the Working Group on HIV and STIs of the Spanish Society of Pediatric Infectious Diseases (SEIP)

Sexually transmitted infections (STIs) constitute a significant public health concern, with an increasing incidence in recent years. The management of these infections among the adolescent population represents a current challenge and should be based in comprehensive educational interventions (such as access to comprehensive sexuality education from early childhood and specialized training in sexual health for health care professionals), preventive strategies (including access to vaccination, implementation of pre- and post-exposure prophylaxis programs, and organized STI screening initiatives), and ensuring free, confidential access to public health care services for adolescents. This approach facilitates timely and appropriate diagnosis and treatment, thereby preventing complications and reducing the stigma associated with these infections. This document describes the main advances in the management of sexually transmitted infections in the adolescent population, with an analysis of the specific characteristics of this vulnerable group.
