Genital ulcer disease: A review

Area of Science:

• Infectious Diseases
• Public Health
• Microbiology

Background:

• Genital ulcer disease (GUD) significantly contributes to global morbidity and mortality.
• GUD is a critical risk factor for HIV acquisition.
• Key causative agents include herpes simplex virus 2 (HSV-2), Treponema pallidum, and Haemophilus ducreyi, with HSV-2 being the most prevalent globally.

Purpose of the Study:

• To review the current epidemiology, clinical presentations (typical and atypical), diagnostic challenges, and management strategies for GUD.
• To highlight the evolving role of HSV-1 in GUD and the limitations of traditional diagnostic methods.
• To emphasize the importance of laboratory confirmation and the syndromic approach in resource-limited settings.

Main Methods:

• Literature search of PubMed and Google using terms like "genital ulcer disease," "epidemiology of genital ulcer disease," and "clinical features of genital ulcer disease."
• Selection of relevant literature to provide current perspectives on GUD.
• Review of clinical presentations, diagnostic methods, and management guidelines.

Main Results:

• HSV-2 remains the leading global cause of GUD, but HSV-1 is increasingly implicated.
• Accurate clinical diagnosis is challenging due to atypical presentations and co-infections.
• Molecular methods offer sensitive and rapid microbiological diagnosis, surpassing limitations of standard tests.

Conclusions:

• Effective management of GUD requires accurate diagnosis, considering both typical and atypical presentations.
• Molecular diagnostics are crucial for timely and precise identification of causative pathogens.
• The syndromic management approach remains vital in settings lacking laboratory facilities.
