Traditional chiefs travelled more than 1,000 kilometres recently through Burkina Faso's northern Sahel in a caravan, organized in cooperation with UNDP, to help stop the spread of HIV/AIDS, which has spread dramatically in the west African country. The three-day car caravan visited the region's two main provinces, Seno and Soum, holding meetings in six towns and villages to alert residents about the epidemic and encourage local HIV/AIDS awareness and prevention activities.
