IN 1982, WHEN AIDS WAS FIRST IDENTIFIED IN SUB-SAHARAN AFRICA, there was very little concern about the roads and the large number of people whose daily activities are connected with the transport/commercial industry. Hence, very little research has been done on transport and commercial networks and their relation to sexual activity, STDs and HIV transmission. The studies conducted so far have shown high levels of HI V incidence on the highways, and both the long distance haulage drivers and the women whose daily activities are connected with the transport/commercial system have been linked to high levels of transmission ofSTDs and AIDS (Tierney 1990).
