Sexually Transmitted Infections: Global Trends, Diagnostic Advances, and Emerging Challenges

Sexually transmitted infections (STIs) continue to pose a major public health challenge and have profound social, economic and health impacts. These infections, which are caused by a variety of bacteria, viruses and parasites, are primarily transmitted through sexual contact, but can also be passed from mother to child during childbirth or through contaminated needles and blood products. Despite advances in medicine and public health, the prevalence of STIs continues to rise, fueled by factors such as stigma, limited access to sexual health services, and evolving pathogens. This review will examine the global burden of STIs and highlight their prevalence and impact on different populations. It will discuss some of the diagnostic challenges that hinder the effective management and control of these infections. It will also discuss the wider public health implications, including the economic costs, and identify emerging challenges and potential strategies to mitigate their impact.
