South Africa's around 35,000 truck drivers are an extremely high-risk group when it comes to contracting and spreading HIV. The drivers spend a lot of time away from home and some visit sex workers at truck stops.
As part of the Trucking Against AIDS project, 12 roadside wellness clinics have been put up on trucking routes around South Africa.
At the clinics drivers are encouraged to be tested and get information on HIV and AIDS and other sexually transmitted infections, STIs.
Since the start the clinics have received more than 4,000 visitors, 42% of whom tested positive for STIs. The clinics have noted a significant reduction in the prevalence of STIs.
Says Monde Qunta, or "Dr Condom" as the drivers call him, who works at a clinic in Nelson Mandela Bay: "I have seen changes. The guys and women use condoms now and there are less STIs compared to when we started."
