Sexually transmitted diseases in Riyadh, Saudi Arabia. A study of patients attending a teaching hospital clinic.

Of 716 men attending consecutively a dermatovenereological clinic in Riyadh, Saudi Arabia, over a period of a year 70·1% had non-specific genital infection, a figure which is four times that for gonorrhoea and 13 times that for syphilis. Most of the patients were single men aged between 20 and 29 years and had acquired their infections abroad. Although Riyadh is a cosmopolitan city with a large foreign population 79% of the infections occurred in local inhabitants.
