ABSTRACT
Introduction Gonorrhoea is caused by the Gram-negative diplococcus Neisseria gonorrhoeae In the UK, the various conditions caused by the bacterium declined in incidence throughout the 1980s and into the early 1990s, but since 1994 it has become more common, In 2002 there were about 26000 cases diagnosed at Genitourinary Medicine clinics in the UK. An unknown number of people were diagnosed in other settings. The increase in cases is thought to be due to increased sexual activity, in particular more people having concurrent sexual partners.
