New Trends in Sexually Transmitted Infections Among Adolescents and Young People: Epidemiology, Clinical and Diagnostic Management

Sexually transmitted infections (STIs) are a significant public health issue, espe- cially among adolescents and young adults. Despite improvements in diagnostic tools and treatments, over 1 million new STIs occur daily worldwide, many of which are asymptomatic. These infections can severely affect quality of life and reproductive health, par- ticularly when contracted at a young age. This review provides an overview of STIs’ recent epidemiology data, clinical trends, and diagnostic challenges in Italian adolescents and young adults, focusing on the Chlamydia trachomatis, Neisseria gonorrhoeae, Treponema pallidum, Thricomonas vaginalis, and Mycoplasma/Ureaplasma species. Worrying new evidence indicates that young women are at a higher risk of contracting STIs than men and multidrug-resistant strains have increased in young heterosexuals. This evidence shows a general change in lifestyle, where a lack of awareness about the risks of STI reflects a significant educational gap. To address the rising STI rates, targeted school educational interventions and innovative multidisciplinary healthcare models, such as the hub-and-spoke approach, are needed.
