Updating the management of sexually transmitted infections

The control of sexually transmitted infections relies on case-finding and treatment of sexual contacts to prevent further transmission. Screening for infections should be tailored to the demographic and sexual risk of the individual. For most sexually transmitted infections, screening is performed on self-collected, non-invasive samples using highly sensitive molecular assays. These are quick and inexpensive. Shorter courses of antivirals for genital herpes are now recommended. New chemoprophylactic strategies for preventing HIV transmission have emerged, including treatment to prevent transmission and the use of antiretrovirals for pre-exposure prophylaxis.
