Abstract:
Infections that cause genital ulcers are one of the themes comprising the Clinical Protocol and Therapeutic Guidelines for Comprehensive Care for People with Sexually Transmitted Infections, published by the Brazilian Ministry of Health in 2020. The Protocol and Guidelines have been developed based on scientific evidence and validated in discussions with specialists. This article addresses clinical genital ulcer syndrome caused by sexually transmitted infections, and its most common etiological agents: Treponema pallidum (syphilis), herpes simplex virus-2 (genital herpes) and herpes simplex virus-1 (perioral herpes), Haemophilus ducreyi (chancroid), Chlamydia trachomatis serotypes L1, L2 and L3 (venereal lymphogranuloma), and Klebsiella granulomatis (donovanosis). Epidemiological and clinical aspects of these infections are presented, as well as guidelines for their diagnosis and treatment, in addition to strategies for surveillance, prevention and control actions, with the purpose of supporting health managers and professionals in the qualification of care.
