Previous crises, such as the Ebola virus disease (EVD) in West Africa in 2014, indicate the direct impact movement restrictions and disease containment efforts have on food availability, access, utilization and violence – particularly gender-based violence (GBV). The importance of maintaining and upscaling food security interventions for the most vulnerable populations, alongside the health sector’s efforts to avert disease spread, is therefore undeniable. The COVID-19 outbreak in South Sudan threatens to paralyze an already fragile food system and negatively impact more than 6.5 million people in South Sudan who remain vulnerable. At the same time, the core national capacities for prevention, preparedness and response for public health events is limited, and the healthcare system has been weakened by years of conflict, poor governance and low investments.
