Although many cases of vaginal discharge are not caused by sexually transmitted infections and do not need to be treated, common curable sexually transmitted infections can present with this symptom. Controlling the spread of sexually transmitted infections and HIV are key public health priorities worldwide.1 Recent advances are changing investigation techniques and the management of vaginal discharge. Clinicians need to be aware of emerging epidemiological data, the different presentations of vaginal discharge, and how to approach their management so that the symptom can be treated according to its aetiology (box 1).

Cervical ectopy can be associated with a mucoid discharge and if symptomatic is widely treated with cryotherapy or diathermy, although evidence to support the effectiveness of these treatments is poor.
Sources and selection criteria
We searched various sources to identify evidence on the aetiology, diagnosis, and treatment of vaginal discharge. Searches of the Cochrane databases, Clinical Evidence, Bandolier, and Medline were undertaken using the keywords “vaginal discharge” and “bacterial vaginosis”, “candidiasis”, “Chlamydia trachomatis”, “gonorrhoea”, “Trichomonas vaginalis”, “nucleic acid amplification techniques”, “polymerase chain reaction”, and “ligase chain reaction”. We consulted generalist and specialist colleagues regarding clinical areas of uncertainty or those lacking evidence.
