It has been known for a long time that people whose jobs require them to travel a lot such as truckers traders seafarers army personnel etc. are extremely vulnerable to HIV and STIs. In the case of truck drivers overnight stays away from home less social control long waiting periods in ports and border stations the availability of commercial sex and other factors work together in creating this vulnerability. In various countries of the world mainly in South Asia South Africa and Western Africa projects have been set up to increase HIV/AIDS awareness among truckers and their occasional sexual partners and teach them about the importance of consistent condom use. In South Africa several roadside container clinics for HIV/AIDS education and treatment of STIs were set up by the road freight industry. In South Africa national HIV prevalence rates grew from 0.8% in 1990 to 22.4% in 1999. By the end of 2001 an estimated five million South Africans were living with HIV/AIDS and 1600 people were contracting HIV daily. Long-distance truck drivers and their sexual partners were found to be especially vulnerable population groups. To counteract the spread of HIV/STIs among its mobile personnel the South African road freight industry set up several mobile health clinics along the main roads of the country. The project is carried out by the Learning Clinic a local NGO. (authors)
