Karen Aweno (48) has tuberculosis (TB). She is a resident of the Agweng camp for internally displaced people (IDPs). For 18 years the Lord's Resistance Army (LRA) rebels have terrorised the Northern provinces of Uganda abducting 20,000 children and forcing 1.6 million people to flee their homes. According to Medecins Sans Frontieres (MSF) the mortality rate among children in some areas is five times the rate internationally agreed to constitute an 'emergency out of control'. The UN's under-secretary general for humanitarian affairs has called Northern Uganda the "largest neglected humanitarian emergency in the world".
