An active conflict in South Sudan in late 2013/early 2014 dis-placed approximately 2 million people over the course of several months. In May 2015, the International Rescue Committee and UNICEF conducted a mixed-methods case study of the impact of that acute emergency on integrated community case management (iCCM) of childhood illness programming in Payinjiar County, Unity State. The objective was to document the operations of an iCCM program during an acute crisis and to assess the program’s ability to continue operations.
