ABSTRACT
Sexually transmitted infection (STI) represents an often under-rated public health concern affecting mainly young, otherwise healthy and economically active adults. There remains stigma associated with diagnosis. This chapter describes clinical risk assessment, anatomical sites requiring testing (penis, urethra, pharynx and rectum) and principles of contact tracing and partner notification for men who have sex with women, and men who have sex with men. Common sexually transmitted pathogens for urethritis are described and treatment outlined, including Neisseria gonorrhoeae, Chlamydia trachomatis, mycoplasma genitalium and trichomonas vaginalis, in addition to genital dermatoses that result in ulcers and warts. The basis for asymptomatic screening of STIs is also described.
