The WHO estimates that 340 million new cases of syphilis, gonorrhoea, chlamydia and trichomoniasis occur annually in adults between 15 and 49 years old. For all STD’s there is a gradient with the vast majority occurring in developing countries, in particular sub-Saharan Africa and Asia. STD’s and their complications rank among the top five disease categories in developing countries for which adults seek health care1. The main factor in the spread of STD’s is unprotected sex especially among high-risk population groups. Not surprisingly venereal diseases occur predominantly in the age groups with greatest sexual activity and more frequently among people in certain vulnerable occupations including mobile and migrant workers such as those in the maritime trades.2
