CARE has been operating in Southern Sudan since 1993, initially providing humanitarian relief to internally displaced people in Western Equatoria. The signing of the Comprehensive Peace Agreement in 2005 allowed CARE to expand into Jonglei and Upper Nile States to support returnees from the refugee camps, and the organization has since broadened its operations to include development programs.
With the outbreak of violence in December 2013, CARE is providing emergency water, sanitation, hygiene services and education, in addition to nutrition and livelihoods assistance. CARE also supports over 40 health facilities in Unity and Upper Nile States, two of the states most heavily affected by fighting.
