As an example, the WHO found that after violence erupted following the 2007 elections in Kenya, "30% of the health facilities are not functioning.  This disruption in the health system is affecting routine health care delivery and emergency care services.  Already there are reports of patients on Anti-Retroviral Therapy for HIV and Tuberculosis treatment being unable to access their drugs." These sorts of shortages are quite common in conflict-affected zones, due to the increased logistical frustrations of avoiding fighting or insurgents who might steal supplies.
