Introduction

Genital herpes is an important public health disease and is the leading cause of genital ulcer disease worldwide. We present the latest evidence based guidelines from the British Association for Sexual Health and HIV (BASHH), the Centers for Disease Control and Prevention (CDC), and other expert committees to provide an up to date account of genital infection with herpes simplex virus (HSV), its clinical features and diagnosis, and a practical approach to management of affected patients. Treatment regimens have largely been based on evidence obtained from randomised controlled trials, while certain new diagnostic tests are limited by lower levels of evidence obtained only from descriptive or case studies.
