WHO Weekly Situation Update on Ongoing Health Emergency Events in South Sudan – Week #: 22; Date: 5th June 2026

Country: South Sudan Source: World Health Organization Please refer to the attached file. Introduction During this reporting period, South Sudan continued to face sustained public health emergency pressures driven by multiple disease outbreaks, climate-related shocks, displacement, and access constraints, which continued to strain response operations and health system capacity. Despite these challenges, progress was recorded across preparedness, surveillance, coordination, and response activities through continued partner collaboration and delivery of critical public health interventions, although operational constraints, resource gaps, and evolving emergency risks remain key concerns. Priority Disease Outbreak and Public Health Threats Updates Cross-Border Ebola Threat to South Sudan: The Ebola Virus Disease (EVD) outbreak caused by the Bundibugyo strain continues in the Democratic Republic of Congo, with 381 cumulative confirmed cases and 64 confirmed deaths reported to date. A total of 6 recoveries have been recorded, while 25 health zones have reported confirmed cases, and 16 healthcare workers have been infected. In Uganda, a total of 16 confirmed cases have been reported across 2 affected districts, including 1 confirmed death, with 13 patients currently admitted, 2 recoveries discharged from care, and 5 healthcare workers infected. Given South Sudan’s absorbent borders, population movement, and strong epidemiological linkages with both countries, the risk of importation remains high. South Sudan continues to strengthen readiness and preparedness measures, with the national EVD readiness score improving from 29% on 18 May to 45% following a repeat EVD Readiness Checklist assessment on 4th June 2026. However, sub-national readiness remains lower than the national average, highlighting gaps in preparedness & readiness capacities at state, county, and point-of-entry levels that require continued investment. Key Readiness activities: Coordination and Surveillance: EVD coordination mechanisms are operational in all 15 priority counties, achieving 95% zeroreporting coverage, with strengthened alert verification, EIOS monitoring, and cross-border collaboration. Point of Entry Readiness: Digital screening is operational at Juba International Airport, while screening and preparedness have been strengthened across Yei, Nimule/Magwi, and Kaya/Morobo PoEs, with over 2, 000 travelers screened at JIA. Case Management and IPC: The Yei Road IDU (8 beds) and Yei Civil Hospital isolation unit (10 beds) are operational, supported by trained health workers, IPC/WASH supplies, PPE, and strengthened isolation capacity. RCCE and Logistics: Risk communication has been scaled up through radio programs, community engagement, and mobile messaging, while laboratory, IPC, specimen transport, and case management supplies have been mobilized to support rapid response readiness.
