Contemporary Challenges in Sexually Transmitted Diseases: From Diagnostics to Drug Resistance

Sexually transmitted diseases (STDs) continue to represent a substantial burden on public health and society worldwide. With significant implications for social, economic, and public health, STDsare a major global health concern. Despite advances in treatment, the global control of STDs is increasingly threatened by high prevalence of asymptomatic infections, delayed diagnosis and the rapid emergence of antimicrobial resistance (AMR). This emergence includes the value of asymptomatic screeningand the ensuing collateral damage resulting from the overuse of our declining potent antimicrobial resources. This review article critically examines current trends in the epidemiology, clinical significance, and laboratory diagnosis of major sexually transmitted pathogens, including Treponema pallidum, Chlamydia trachomatis, Trichomonas vaginalis, human papillomavirus, herpes simplex virus, and emerging sexually transmissible infections. Major emphasis is focused on contemporary diagnostic technologies and strategies, with a major focus on nucleic acid-based and point-of-care testing and their applicability in routine testing. The review also highlights evolving AMR patterns, resistance-guided therapy, and the role of global and national surveillance systems in informing treatment guidelines, with the integration of diagnostic strategies with resistance-guided therapy and surveillance systems. Strengthening diagnostic capacity, antimicrobial stewardship, and integrated surveillance is essential to mitigate resistance, improve patient outcomes, and advance effective STD management in venereology practice.
