Newer and emerging sexually transmitted infections: A narrative review.

Sexually transmitted infections (STIs), including traditionally curable diseases like syphilis and gonorrhoea, have seen a recent resurgence. Concurrently, newer atypical infections presenting as STIs have emerged, driven by changes in pathogen virulence, host behaviours, and environmental factors. The spectrum of STIs is expanding due to evolving behaviours, globalisation, and pathogen adaptability. This review aims to highlight key viral, bacterial, fungal, and enteric infections that are newly identified or increasingly transmitted through sexual contact, introducing the concept of sexually transmissible infections. Though sexual transmission plays a minor role in their spread, it cannot be neglected and thus requires heightened awareness among clinicians and public health officials to ensure timely identification, management, and prevention.
