Ebola Cross-Border Preparedness: WASH and IPC Standards for South Sudan Health Facilities

South Sudan's Equatoria States share a land border with both Uganda and the Democratic Republic of the Congo — the two countries at the centre of the current Bundibugyo virus disease outbreak that WHO declared a Public Health Emergency of International Concern on 17 May 2026. As of 24 May, more than 1,010 suspected and confirmed cases and at least 231 deaths had been reported, with transmission continuing to spread across Ituri Province and into Uganda. For WASH officers and health facility managers in South Sudan, the question is not whether to prepare but how to prepare — fast, with the supplies and infrastructure already in-country.

The challenge is severe. A peer-reviewed cross-sectional study of 151 health facilities in six high-risk States of South Sudan, published in the Pan African Medical Journal in 2022 and commissioned by WHO, found that only 13.19% of facilities had functioning IPC committee structures and only 21.85% had relevant guidelines or standard operating procedures. The three Equatoria States — Western, Central, and Eastern Equatoria — which sit directly on the DRC and Uganda borders, recorded the worst preparedness scores in the entire study. Western Equatoria scored 34.45% overall, the lowest of all six States assessed.

That baseline was poor before the current outbreak was declared. It has not improved at the speed required. NGO programme managers and WASH teams operating in southern South Sudan need to act on their WASH and IPC gaps now, in the preparedness window that still exists. This post sets out the specific WASH requirements for non-ETU health facilities on the Ebola preparedness pathway — primary health care centres, county hospitals, and IDP site health posts — and identifies the procurement priorities that can close the gap between current baseline and minimum acceptable readiness.

Quick answers for field teams:

• WHO requires a functional handwashing point at every patient entry and every point of care in any health facility designated for Ebola preparedness, including those not acting as treatment centres

• Free residual chlorine of at least 0.5 mg/L must be maintained at all water distribution points within health facilities; during active outbreak response this rises to 1.0 mg/L

• WHO's 2023 IPC guideline for Ebola and Marburg disease specifies 40–60 litres of water per patient per day for general health facilities and at least 100 litres per patient per day in isolation units — far above standard Sphere minimums

• P&G Purifier of Water sachets are an appropriate pre-treatment for turbid source water in Equatoria and southern health facilities before chlorine disinfection is applied

• South Sudan's UNGM-registered in-country supplier, Specialized Logistics Solutions (SLS), holds pre-positioned stock of chlorination products, water treatment sachets, and storage bladders in Juba for rapid dispatch

Why the Equatoria Border Zone Is the Highest-Risk Area in South Sudan Right Now

South Sudan's southern border is not a hard boundary. Free population movement for trade, family, and seasonal labour has always characterised the Equatoria-Uganda-DRC borderlands. The same movement pattern that WHO identified as driving Ebola transmission dynamics in the 2018–19 North Kivu outbreak is present in this corridor — informal crossings, shared market networks, and migratory routes that do not pass through monitored ports of entry.

WHO's 17 May 2026 PHEIC statement explicitly directed that unaffected States Parties with land borders adjoining States Parties with documented Bundibugyo virus disease transmission should urgently enhance their preparedness and readiness capacity. For South Sudan, this is not a distant contingency. Exit screening has been implemented at border points, but, as WHO also noted, the large network of informal healthcare facilities and ongoing population mobility means that a case presenting to a primary health care centre in Yambio or Nimule cannot be ruled out.

The consequences of an undetected case presenting to a health facility without functioning IPC-WASH infrastructure are amplified in this environment. At least four deaths among healthcare workers in DRC were reported in the PHEIC statement, attributed directly to healthcare-associated transmission and gaps in infection prevention and control. An unprepared health facility does not just fail to contain an outbreak — it amplifies it.

What WASH Standards Apply to Non-ETU Health Facilities

Most WASH guidance for Ebola focuses on Ebola Treatment Unit requirements. The less-discussed operational challenge is what standards apply to the far larger number of health facilities that are not designated as ETUs but may nonetheless receive a suspected case before referral, or may need to provide care for contacts under monitoring.

WHO's 2023 infection prevention and control guideline for Ebola and Marburg disease sets the minimum water supply for any health facility on the Ebola preparedness pathway at 40 to 60 litres per patient per day for general wards. Isolation units — including any designated holding room for a suspected case before transfer to an ETU — require a minimum of 100 litres per patient per day. The WHO guideline further specifies that all handwashing points must have running water or, where that is not available, a tippy-tap or bucket-and-tap equivalent with soap or 70% alcohol hand rub available at the point of use at all times.

The WHO WASH FIT tool, which underpinned the South Sudan IPC/WASH study, assesses seven minimum WASH requirements for health facilities: reliable water supply, functional handwashing points at care stations, toilets accessible to patients and staff separately, waste management systems, safe disposal of sharps and infectious waste, environmental cleaning protocols, and a designated cleaning area. In the South Sudan study, the IPC/WASH supplies component scored below 50% across most of the six high-risk States, even during an active EVD preparedness programme funded at $30.5 million. This points to a procurement and logistics gap rather than a knowledge gap.

The Specific Supply Priorities: Chlorine, Treatment, and Storage

Three product categories address the majority of WASH preparedness gaps at non-ETU health facilities in southern South Sudan.

Chlorine for surface disinfection and water treatment. HTH Calcium Hypochlorite at 65–70% available chlorine is the correct bulk product for both applications. For surface decontamination in a suspected-case isolation room, a 0.5% chlorine solution is required. A standard 45 kg drum of 65% HTH treats approximately 585,000 litres of water to a 1 mg/L dose — the elevated standard recommended during active Ebola response — or produces roughly 9,000 litres of 0.5% surface decontamination solution. Facility managers need to calculate their isolation capacity, patient throughput, and cleaning frequency to determine minimum drum requirements before a case presents.

Point-of-use water treatment for turbid source water. Health facilities in Equatoria's rural areas draw water from boreholes, rivers, and springs with variable quality. Chlorine disinfection is ineffective above 5 NTU turbidity, and source water in Equatoria during the onset of the rainy season regularly exceeds this threshold. P&G Purifier of Water sachets are the operationally correct pre-treatment product: each sachet treats 10 litres of highly turbid water by coagulation and disinfection within 30 minutes, reducing turbidity to near-zero before chlorine residual is established. They require no electricity, no specialist equipment, and minimal training.

Water storage for continuous supply. Ebola preparedness requires continuous water supply — isolation rooms cannot be cleaned between shifts if water supply is intermittent. At 40–60 litres per patient per day for general wards and 100 litres for isolation, a ten-bed health facility with one isolation room needs a minimum of 650 litres of stored water per day even without accounting for staff requirements. Butyl Products (UK) water bladders and tanks, available through Specialized Logistics Solutions (SLS), provide the flexible on-site storage capacity appropriate for this setting.

Structural Gaps: Isolation Capacity Without an ETU

The South Sudan IPC/WASH study identified infrastructure compliance as one of the better-performing components at 54.69% — a figure largely attributable to the four isolation units built under the 2018–2020 EVD preparedness programme in Equatoria. But isolation infrastructure built for a preparedness programme that ended years ago may not be in operational condition today.

A functional isolation room for a suspected Ebola case requires separated air flow or negative pressure, a dedicated toilet or latrine accessible only from the isolation space with a chlorine solution bucket immediately outside the door, a handwashing station with running water or a functional tippy-tap and soap supply at the entry point, and a donning and doffing area with adequate space for PPE removal without self-contamination.

Where permanent isolation infrastructure does not exist or is not operational, a modular shelter erected adjacent to the main facility — physically separated, with its own WASH infrastructure — provides an equivalent solution. Hallgruppen modular structures are available through Specialized Logistics Solutions (SLS) and can be erected within 72 hours with basic tools and local labour. At the health facility level, a single modular unit provides the isolation room, anteroom, and PPE station required for a non-ETU suspected case holding space.

Procurement Timing: The Window That Still Exists

The PHEIC declaration on 17 May 2026 opened a preparedness window for South Sudan. That window will close either when a case is confirmed in-country — at which point response replaces preparedness — or when the outbreak is brought under control in DRC and Uganda. Neither outcome is certain on a short timeline. As of 26 May 2026, case counts in DRC have exceeded 1,000 and Uganda has confirmed seven cases.

Procurement decisions made this week will determine whether facilities in Yambio, Torit, Nimule, and Juba have the WASH supplies required to safely receive and isolate a suspected case when one presents. The 2018–19 experience in North Kivu demonstrated that preparedness materials procured after a cross-border case is confirmed arrive too late to protect the health workers who manage the first presenting patients.

The South Sudan IPC/WASH study concluded that inadequate supply chain management for essential IPC/WASH supplies was a primary driver of low facility readiness, independent of training or knowledge levels. The implication for NGO and UN procurement teams is direct: the gap between current baseline and minimum readiness is a logistics and supply problem, solvable through procurement orders placed now.

What This Means for Your Programme

South Sudan is not in the Ebola response zone — but it shares a border with both affected countries, has a documented history of cross-border case importation risk from the 2018–19 outbreak, and enters this period with health facility IPC/WASH readiness below the minimum threshold required to safely manage a suspected case. Every week of preparedness inaction translates directly into healthcare worker exposure risk when the first case eventually presents.

The operational priorities for programmes in Equatoria and southern South Sudan are: audit isolation infrastructure in your facilities, calculate WASH supply requirements for a 21-day preparedness stock (the contact monitoring period under WHO guidance), place procurement orders for HTH chlorine, P&G Purifier of Water sachets, and bladder tank storage capacity, and confirm staff have received point-of-care handwashing training.

Specialized Logistics Solutions (SLS) holds pre-positioned stock of HTH Calcium Hypochlorite drums, P&G Purifier of Water sachets, Aquatabs 67mg tablets, and Butyl Products water bladders in Juba and Kampala, available for rapid dispatch. Contact the team at sales@maji-safi.org.

Frequently Asked Questions

What WASH requirements apply to a health facility that is NOT an Ebola Treatment Unit?

WHO's 2023 IPC guideline for Ebola and Marburg disease sets the minimum at 40–60 litres of water per patient per day in general wards and 100 litres per patient per day in isolation units. Every patient contact point must have a functional handwashing station. Surfaces in any area where a suspected case is assessed must be decontaminated with a 0.5% chlorine solution after contact. These standards apply to any facility on the Ebola preparedness pathway, including primary health care centres and county hospitals.

How should a South Sudan health facility calculate chlorine stock for preparedness?

Calculate the number of isolation beds, multiply by 100 litres per bed per day for supply requirements, then calculate the chlorine required to maintain 1.0 mg/L FRC in that supply volume and to prepare 0.5% decontamination solution for daily surface cleaning. HTH Calcium Hypochlorite at 65% active chlorine requires approximately 1.5 grams per 1,000 litres of water to achieve 1 mg/L FRC. A minimum 21-day preparedness stock — the Ebola contact monitoring window — is the planning standard.

Why is P&G Purifier of Water needed if the facility already has chlorine tablets?

Chlorine tablets and HTH calcium hypochlorite lose most of their disinfection effectiveness in water with turbidity above 5 NTU. Health facilities in Equatoria drawing from surface sources during the rainy season will regularly encounter water above this threshold. P&G Purifier of Water sachets combine coagulation and disinfection, reducing turbidity to near-zero before the disinfection step, making them the correct primary treatment for any turbid source water before chlorination is applied or relied upon.

What is the correct isolation infrastructure for a non-ETU health facility expecting a suspected Ebola case?

At minimum: a room with dedicated ventilation that does not feed general ward air circuits, a dedicated toilet or latrine accessible only from the isolation space, a handwashing station with soap and running water or equivalent at the room entry, and a donning and doffing area outside the isolation room where PPE can be removed safely. If existing infrastructure cannot meet these requirements, a modular shelter erected adjacent to the main facility is a field-appropriate solution that can be installed within 72 hours.

Has there been formal assessment of South Sudan health facility readiness for Ebola?

Yes. A WHO-commissioned cross-sectional study published in the Pan African Medical Journal in 2022 (Freeman et al., doi: 10.11604/pamj.supp.2022.42.1.33906) assessed 151 health facilities across six high-risk States including the three Equatoria States. The study found only 13.19% had functioning IPC committee structures, only 21.85% had relevant guidelines or SOPs, and Western Equatoria — the State bordering both Uganda and DRC — had the lowest overall IPC/WASH readiness score of all States assessed at 34.45%.
