Sub-Saharan Africa is the continent most affected by HIV/AIDS, which is the leading cause of death. Throughout the West and Central African region, the border zones appear to be the areas most at risk due to the mobility of the population, which consists mainly of truck drivers, traders, women offering various services, young boys and girls accompanying their parents or guardians or wandering for survival, sex workers crossing borders, etc. The nonconformism of vulnerable groups settled or using the corridors can be perceived in addition to distance of the borders.
