Assessing attitudes towards violence against women and girls, their determinants and health-seeking behaviour among women and men in South Sudan: a cross-sectional national survey.

OBJECTIVE: Investigating attitudes accepting two categories of violence against women and girls (VAWG) (intimate partner violence-IPV-and other expressions of VAWG) and their association with seven demographic/social determinants and health-seeking behaviours in South Sudan. DESIGN: Cross-sectional study using data from the South Sudan National Household Survey 2020. SETTING: South Sudan. PARTICIPANTS AND METHODS: 1741 South Sudanese women and 1739 men aged 15-49 years; data captured between November 2020 and February 2021 and analysed using binary logistic regression. RESULTS: People with secondary or higher education displayed attitudes rejecting acceptance of IPV (OR 0.631, 95% CI 0.508 to 0.783). Women and men living in states with more numerous internally displaced people (IDP) or political/military violence had attitudes accepting IPV more than residents of less violence-affected regions (OR 1.853, 95% CI 1.587 to 2.164). Women had a higher odd of having attitudes accepting IPV than men (OR 1.195, 95% CI 1.014 to 1.409). People knowing where to receive gender-based violence healthcare and psychological support (OR 0.703, 95% CI 0.596 to 0.830) and with primary (OR 0.613, 95% CI 0.515 to 0.729), secondary or higher education (OR 0.596, 95% CI 0.481 to 0.740) displayed attitudes rejecting acceptance of other expressions of VAWG. People residing in states with proportionately more IDP and who accepted IPV were more likely to have attitudes accepting other expressions of VAWG (OR 1.699, 95% CI 1.459 to 1.978; OR 3.195, 95% CI 2.703 to 3.775, respectively). CONCLUSION: Attitudes towards accepting VAWG in South Sudan are associated with women's and men's education, gender, residence and knowledge about health-seeking behaviour. Prioritising women's empowerment and gender transformative programming in the most conflict-affected areas where rates of VAWG are higher should be prioritised along with increasing girls' access to education. A less feasible strategy to decrease gender inequalities is reducing insecurity, military conflict, and displacement, and increasing economic stability.

Predictors of under-weight among children younger than 24 months in Nimule Border Town, Eastern Equatoria State, South Sudan: a community-based cross sectional study.

BACKGROUND: Underweight is a public health problem globally, and more severe in South Sudan with wide sub-regional differences. In Nimule border town, which represents other border towns in South Sudan, data on underweight among children below two years is unavailable. Thus, this study set out to assess predictors of underweight among children younger than 24 months in Nimule border town, Magwi County, Eastern Equatoria State, South Sudan. METHODS: An analytical cross-sectional study was conducted in Nimule boarder town targeting 390 children younger than two years. Systematic sampling and simple random sampling methods were used. Data were collected through a researcher-administered questionnaire with both open and closed ended questions. Data was entered in EpiData and then exported into Statistical Package for Social Sciences research (SPSS) version 20 for analysis. Descriptive data analysis was conducted and data were summarized into frequencies and percentages, means with standard deviations, and medians with interquartile ranges. Bivariate analysis was conducted with the Chi-squared and Fisher's exact tests for categorical independent variables, and the student's t-test for numerical variables. Finally, multivariate analysis was done via logistic regression analysis and results were stated as odds ratios (OR) with corresponding 95% confidence interval (CI). The level of statistical significance was set at 5%. RESULTS: Out of the total 390 participants, 112 (28.7%) were under weight. The study showed primary (aOR, 0.38; 95% CI, 0.12-1.18; P = 0.095) and secondary (aOR, 0.37; 95% CI, 0.12-1.17; P = 0.091 levels of education were associated with underweight but not tertiary level of education (aOR, 0.76; 95% CI, 0.21-2.74; p = 0.671). Household income of 5000 to 10,000 (aOR, 0.26; 95% CI, 0.10-0.68; P = 0.006) and above 10,000 (aOR, 0.11; 95% CI, 0.04-0.28; P < 0.001) South Sudanese pounds, supplementary feeding before 6 months (aOR; 0.01; 95% CI, 0.02-0.05; P < 0.001) were associated with underweight and irregular hand washing (aOR; 2.17; 95% CI, 1.14-4.11; P = 0.018) was associated with increased odds of underweight. CONCLUSIONS: This study established a high prevalence of underweight. Maternal level of education particularly primary, secondary, higher household incomes in excess of 5,000 South Sudanese pounds reduced the risk of underweight. While irregular hand washing was a risk factor for underweight.

"Implementation of intensified COVID-19 vaccination optimization (ICVOPT) campaigns strategy in complex humanitarian emergency settings and hard-to-reach areas; a case of South Sudan".

INTRODUCTION: The COVID-19 pandemic is still a public health concern in South Sudan having caused suffering since the first case of COVID-19 was introduced on 28th February 2020. COVAX vaccines have since been introduced using a number of strategies including fixed site, temporary mobile, hit and run in flooded and conflict affected areas. We aim to describe the 2 ICVOPT campaigns that were conducted to improve the uptake and document lessons learnt during the initial rollout of the COVID-19 vaccination programin South Sudan between February 2022 and June 2022 each lasting for 7-days. METHODOLOGY: We conducted an operational cross-sectional descriptive epidemiological study of a series of the intensified COVID-19 vaccination Optimization (ICVOPT) campaigns from February 2022 to June 2022. Before the campaign, a bottom up micro-planning was conducted, validated by the County Health Departments (CHDs) and national MOH team. Each of the 2 campaigns lasted for 7 days targeting 30% of the eligible unvaccinated target population who were18 years and above. Each team consisted of 2 vaccinators, 2 recorders and 1 mobilizer. The teams employed both fixed site, temporary mobile, hit and run in flooded and conflict affected areas. The number of teams were calculated based on the daily workload per day (80 persons per team/day) for the duration of the campaigns. RESULTS: A total of 444,030 individuals were vaccinated with primary series COVID-19 vaccine (J&J) out of the targeted 635,030 persons. This represented 69.9% of target population in the selected 28 counties and 10 states of South Sudan in 7 days' ICVOPT campaigns. More eligible persons were reached in 7 days campaigns than the 9 months of rollout of the COVID-19 vaccine prior to ICVOPT campaigns using the fixed site strategy at the health facility posts. CONCLUSION: Intensified COVID-19 vaccination Optimization (ICVOPT) campaigns were vital and fast in scaling up vaccination coverages as compared to the fixed site vaccination strategies (2022 progress report on the Global Action Plan for Healthy Lives and Well-being for All Stronger collaboration for an equitable and resilient recovery towards the health-related Sustainable Development Goals, incentivizing collaboration, 2022) in complex humanitarian emergency settings and hard-to-reach areas of South Sudan.

Measuring refugees' capabilities: translation, adaptation, and valuation of the OxCAP-MH into Juba Arabic for use among South Sudanese male refugees in Uganda.

BACKGROUND: Forcibly displaced populations are highly vulnerable to psychosocial distress and mental disorders, including alcohol misuse. In an ongoing trial that seeks to develop a transdiagnostic intervention addressing psychological distress and alcohol use disorders among conflict-affected populations, we will carry out a cost-effectiveness evaluation using a capability-based Oxford Capabilities Mental Health (OxCAP-MH) measure. The OxCAP-MH is a 16-item questionnaire developed from the Capability Approach, that covers multiple domains of functioning and welfare. The aim of the current paper is to present the results of the translation, cultural adaptation and valuation of the OxCAP-MH into Juba Arabic for South Sudanese refugees living in Uganda. We adhered to the official Translation and Linguistic Validation process of the OxCAP-MH. To carry out the translation, the Concept Elaboration document, official English version of the OxCAP-MH, and the Back-Translation Review Template were used. Four independent translators were used for forward and back translations. The reconciled translated version was then piloted in two focus group discussions (N = 16) in Rhino refugee settlement. A most important to least important valuation of the sixteen capability domains covered in the OxCAP-MH was also done. RESULTS: The Juba Arabic version of the OxCAP-MH was finalized following a systematic iterative process. The content of the Juba Arabic version remained unchanged, but key concepts were adapted to ensure cultural acceptability, feasibility, and comprehension of the measure in the local context of Rhino refugee settlement. Most participants had low levels of literacy and required support with filling in the tool. Participants suggested an additional capability that is currently not reflected in the OxCAP-MH, namely access to food. Furthermore, discussions around the valuation exercise of the sixteen domains led to two separate importance scales, which showed relevant differences. CONCLUSIONS: In this context, the OxCAP-MH was considered culturally acceptable. The valuation exercise proved cognitively demanding. Participants voiced confusion over how to answer the questions on the OxCAP-MH instrument due to low levels of literacy. These concerns invite consideration for future research to consider how measures such as the OxCAP-MH can be made more accessible to individuals with low literacy rates in resource poor settings.

Health and well-being of young mothers displaced by conflict: Experiences from South Sudan and the Kurdistan Region of Iraq.

Giving birth during adolescence is linked to a variety of negative outcomes, including poor health and well-being. Girls who have been displaced by conflict are at increased risk for becoming young mothers. While prevalence rates and health outcomes have been documented, rarely have the complex personal narratives of early motherhood been examined from the perspectives of mothers themselves, particularly in the Global South. This study relies on in-depth, inductive, narrative analysis of qualitative interviews with 67 young mothers and 10 relatives in South Sudan and the Kurdistan Region of Iraq (KRI) who had been displaced by conflict. This study provides deep insights into the contributing circumstances and consequences of young motherhood from sexual and reproductive health and well-being perspectives, with additional insights on mothering in humanitarian crisis.

From humanitarian crisis to employment crisis: The lives and livelihoods of South Sudanese refugee health workers in Uganda.

Despite the many benefits of refugee health workers for health systems, they commonly face challenges integrating into host country workforces. The Global Code of Practice on International Recruitment of Health Personnel, which should monitor and protect migrant health workers, offers little guidance for refugees and research is needed to inform strategy. Based on interviews with 34 refugee health workers and 10 leaders across two settlements supporting populations fleeing the humanitarian crisis in South Sudan since 2013, we describe the governance and social dynamics affecting South Sudanese refugee health worker employment in Uganda. Refugees in Uganda legally have the right to work but face an employment crisis. Refugee health workers report that systemic discrimination, competition from underemployed domestic workers, unclear work permit rules and expensive credentialling processes exclude them from meaningful work in public health facilities and good jobs in the humanitarian response. This pushes them into unchallenging roles in private clinics, poorly remunerated positions on village health teams or out of the health sector altogether. Health system strengthening initiatives in Uganda to integrate humanitarian and government services and to deter the domestic workforce from emigration have overlooked the potential contributions of refugee health workers and the employment crisis they face. More effort is needed to increase fairness in public sector recruitment practices for refugee health workers, support credentialling, training opportunities for professional and non-professional cadres, job placements, and to draw attention to the public benefits of refugee health worker employment alongside higher spending on human resources for health.

Simplified treatment protocols improve recovery of children with severe acute malnutrition in South Sudan: results from a mixed methods study.

BACKGROUND: As part of COVID-19 mitigation strategies, emergency nutrition program adaptations were implemented, but evidence of the effects is limited. Compared to the standard protocol, the full adapted protocol included adapted admissions criteria, simplified dosing, and reduced visit frequency; partially adapted protocols consisting of only some of these modifications were also implemented. To enable evidence-based nutrition program modifications as the context evolved, this study was conducted to characterize how protocol adaptations in South Sudan affected Outpatient Therapeutic Feeding Program outcomes. METHODS: A mixed methods approach consisting of secondary analysis of individual-level nutrition program data and key informant interviews was used. Analyses focused on program implementation and severe acute malnutrition treatment outcomes under the standard, full COVID-19 adapted, and partially adapted treatment protocols from 2019 through 2021. Analyses compared characteristics and outcomes by different admission types under the standard protocol and across four different treatment protocols. Regression models evaluated the odds of recovery and mean length of stay (LoS) under the four protocols. RESULTS: Very few (1.6%; n = 156) children admitted based on low weight-for-height alone under the standard protocol would not have been eligible for admission under the adapted protocol. Compared to the full standard protocol, the partially adapted (admission only) and partially adapted (admission and dosing) protocols had lower LoS of 28.4 days (CI - 30.2, - 26.5) and 5.1 days (CI - 6.2, - 4.0); the full adapted protocol had a decrease of 3.0 (CI - 5.1, - 1.0) days. All adapted protocols had significantly increased adjusted odds ratios (AOR) for recovery compared to the full standard protocol: partially adapted (admission only) AOR = 2.56 (CI 2.18-3.01); partially adapted (admission + dosing) AOR = 1.78 (CI 1.45-2.19); and fully adapted protocol AOR = 2.41 (CI 1.69-3.45). CONCLUSIONS: This study provides evidence that few children were excluded when weight-for-height criteria were suspended. LoS was shortest when only MUAC was used for entry/exit but dosing and visit frequency were unchanged. Significantly shorter LoS with simplified dosing and visit frequency vs. under the standard protocol indicate that protocol adaptations may lead to shorter recovery and program enrollment times. Findings also suggest that good recovery is achievable with reduced visit frequency and simplified dosing.

A quasi-experimental study to estimate effectiveness of seasonal malaria chemoprevention in Aweil South County in Northern Bahr El Ghazal, South Sudan.

BACKGROUND: Seasonal malaria chemoprevention (SMC) is an effective intervention to prevent malaria in children in locations where the burden of malaria is high and transmission is seasonal. There is growing evidence suggesting that SMC with sulfadoxine-pyrimethamine and amodiaquine can retain its high level of effectiveness in East and Southern Africa despite resistance concerns. This study aims to generate evidence on the effectiveness of SMC when delivered under programmatic conditions in an area with an unknown anti-malarial drug resistance profile in the Northern Bahr el-Ghazal region of South Sudan. METHODS: A non-randomized quasi experimental study was conducted to compare an intervention county with a control county. Five monthly SMC cycles were delivered between July and November 2022, targeting about 19,000 children 3-59 months old. Data were obtained from repeated cross-sectional household surveys of caregivers of children aged 3-59 months using cluster sampling. Wave 1 survey took place in both counties before SMC implementation; Waves 2 and 3 took place after the second and fourth monthly SMC cycles. Difference-in-differences analyses were performed by fitting logistic regression models with interactions between county and wave. RESULTS: A total of 2760 children were sampled in the study across the three survey waves in both study counties. Children in the intervention arm had 70% lower odds of caregiver-reported fever relative to those in the control arm during the one-month period prior to Wave 2 (OR: 0.30, 95% CI 0.12-0.70, p = 0.003), and 37% lower odds in Wave 3 (OR: 0.63, 95% CI 0.22-1.59, p = 0.306) after controlling for baseline difference between counties in Wave 1. Odds of caregiver-reported RDT-confirmed malaria were 82% lower in the previous 1-month period prior to Wave 2 (OR: 0.18, 95% CI 0.07-0.49, p = 0.001) and Wave 3 (OR: 0.18, 95% CI 0.06-0.54, p = 0.003). CONCLUSION: These results show high effectiveness of SMC using SPAQ in terms of reducing malaria disease during the high transmission season in children 3-59 month. Despite the promising results, additional evidence and insights from chemoprevention efficacy cohort studies, and analyses of relevant resistance markers, are required to assess the suitability of SMC for this specific context.

Vaccination coverage and adverse events following a reactive vaccination campaign against hepatitis E in Bentiu displaced persons camp, South Sudan.

INTRODUCTION: Hepatitis E (HEV) genotypes 1 and 2 are the common cause of jaundice and acute viral hepatitis that can cause large-scale outbreaks. HEV infection is associated with adverse fetal outcomes and case fatality risks up to 31% among pregnant women. An efficacious three-dose recombinant vaccine (Hecolin) has been licensed in China since 2011 but until 2022, had not been used for outbreak response despite a 2015 WHO recommendation. The first ever mass vaccination campaign against hepatitis E in response to an outbreak was implemented in 2022 in Bentiu internally displaced persons camp in South Sudan targeting 27,000 residents 16-40 years old, including pregnant women. METHODS: We conducted a vaccination coverage survey using simple random sampling from a sampling frame of all camp shelters following the third round of vaccination. For survey participants vaccinated in the third round in October, we asked about the onset of symptoms experienced within 72 hours of vaccination. During each of the three vaccination rounds, passive surveillance of adverse events following immunisation (AEFI) was put in place at vaccination sites and health facilities in Bentiu IDP camp. RESULTS: We surveyed 1,599 individuals and found that self-reported coverage with one or more dose was 86% (95% CI 84-88%), 73% (95% CI 70-75%) with two or more doses and 58% (95% CI 55-61%) with three doses. Vaccination coverage did not differ significantly by sex or age group. We found no significant difference in coverage of at least one dose between pregnant and non-pregnant women, although coverage of at least two and three doses was 8 and 14 percentage points lower in pregnant women. The most common reasons for non-vaccination were temporary absence or unavailability, reported by 60% of unvaccinated people. Passive AEFI surveillance captured few mild AEFI, and through the survey we found that 91 (7.6%) of the 1,195 individuals reporting to have been vaccinated in October 2022 reported new symptoms starting within 72 hours after vaccination, most commonly fever, headache or fatigue. CONCLUSIONS: We found a high coverage of at least one dose of the Hecolin vaccine following three rounds of vaccination, and no severe AEFI. The vaccine was well accepted and well tolerated in the Bentiu IDP camp community and should be considered for use in future outbreak response.

Empowerment Transformation Training Reduces Rape Among Girls and Young Women in South Sudan and the Kakuma Refugee Camp.

PURPOSE: Rape occurs at high rates in South Sudan and Kakuma refugee camps, a region characterized by armed conflict, gender inequity, and economic crisis. To date, we know little about how to prevent rape in this region of the world. As such, the purpose of this study was to examine outcomes of Empowerment Transformation Training (ETT) (an adapted empowerment self-defense program; empowerment self-defense) among female participants in South Sudan and the Kakuma refugee camp. METHODS: Schools were assigned to the treatment (ETT) condition (n = 7) or control (life skills) condition (n = 9) and used as the unit of analysis given the cluster-randomized design. Female participants anonymously completed a baseline (T1) and 12-month follow-up (T2) paper and pencil survey. RESULTS: Annual rape victimization rates decreased from 10.7% to 5.5% in the ETT schools (risk ratio [RR] = 0.51); there was no change in the control schools (10.0%-9.0%). Empowerment Transformation Training (ETT) schools had increased confidence at T2 (T1: 42.4%; T2: 75.4%; RR = 1.79) and greater rates of confidence at T2 compared to control schools (54.3%; RR = 1.39). Knowledge of effective self-defense strategies (T2) was greater for ETT schools (47.4%) compared to control schools (30.1%) (RR = 1.57). DISCUSSION: The ETT program reduced rates of rape, increased confidence, disclosures of rape (among victims), and knowledge of effective self-defense strategies. Empowerment self-defense programs are a critical component to rape prevention across global communities, including those characterized by armed conflict, gender inequity, and economic crisis.

Lessons From the COVID-19 Pandemic Response Implementation: A Case Study of South Sudan and Sierra Leone.

INTRODUCTION: The COVID-19 pandemic caused havoc to health systems worldwide and in countries that already had weak health systems. There are lessons to be learned that could contribute to improved response preparedness to future public health emergencies, but there is little documentation on best practices in fragile countries. We describe lessons from South Sudan and Sierra Leone during the COVID-19 response implementation. METHODS: We conducted a retrospective descriptive analysis of COVID-19 vaccination implementation at national and subnational levels between 2020 and 2022 in South Sudan and Sierra Leone to identify those practices that had a positive impact on public health. RESULTS: Several interventions were identified that not only improved the COVID-19 situation but also had a positive effect on routine immunizations. The development of a near-real-time vaccination dashboard gave stakeholders a quick look at vaccine implementation, allowing them to make decisions based on current data. The experience acquired from deploying the COVID-19 dashboard has since been applied to the development of a routine immunization dashboard in South Sudan. Surge vaccination was an effective approach to improving COVID-19 vaccination uptake. A measles reactive campaign was conducted during the initial stages of the pandemic when movement was restricted; experience gained from that effort was subsequently applied to COVID-19 mass vaccination initiatives and outbreak reactive campaigns. Additional vaccinators recruited for COVID-19 response also received comprehensive Immunization in Practice training, allowing them to provide routine childhood vaccinations alongside COVID-19 vaccination, contributing to the maintenance of routine vaccination services in both countries. CONCLUSION: Lessons were learned during the COVID-19 response implementation that have had a positive impact on routine health services. However, it is essential that these effects are maintained and further refined to strengthen the country's preparedness for future public health emergencies and better support the broader immunization service delivery.

Leveraging the CORE Group Partners Project Polio Infrastructure to Integrate COVID-19 Vaccination and Routine Immunization in South Sudan.

INTRODUCTION: Countries with fragile health systems like South Sudan experienced significant impacts on routine immunization during the COVID-19 pandemic. Routine immunization in children aged younger than 1 year declined due to pandemic-related constraints and was compounded by the introduction of the COVID-19 vaccine, which was met with hesitancy and reluctance. When South Sudan reported the first COVID-19 case in March 2020, the CORE Group Partners Project (CGPP) rapidly integrated the COVID-19 outbreak response into its ongoing polio eradication activities, leveraging the existing polio infrastructure and human resources. We describe the integration process, results, and challenges and detail the impact of the integration on coverage for both routine immunization and COVID-19 vaccinations. METHODS: Efforts to integrate COVID-19 vaccination and routine immunization service delivery were implemented in 5 phases: assessing the need, developing multisector collaborations, developing a service delivery plan, assessing implementation readiness, and implementing and evaluating the service delivery plan. Integration efforts prioritized coordination, training vaccinators and volunteers, development of microplans, data management, and last-mile vaccine delivery. Integrated service delivery was implemented through "one-stop shop" sessions where communities accessed routine immunizations for children, COVID-19 vaccinations for adults, and other primary health services. RESULTS: Integrating health service delivery contributed to improved routine immunization coverage among children, improved COVID-19 vaccination coverage among adults, reduced cost for service delivery, and increased access to more comprehensive health services in hard-to-reach communities. COVID-19 vaccinations were delivered at US$4.70 per dose, a cost substantially lower than other reported delivery mechanisms. CONCLUSION: Integration can yield positive results and improve access to vaccination and other health services for communities. However, it requires clear policy guidelines, commitment, and strong collaboration. Challenges included resistance from stakeholders, overstretched human resources, and diversion of funding and attention from program areas, which were overcome through deliberate high-level advocacy, partnership, and intensified community engagement.

Risk factors for food contamination among children discharged from community management of acute malnutrition programmes in South Sudan: A cross-sectional study and hazard analysis critical control point approach.

Children under-5 years of age are particularly vulnerable to severe acute malnutrition (SAM), and the risk factors associated with relapse to SAM are poorly understood. Possible causes are asymptomatic or symptomatic infection with enteric pathogens, with contaminated food as a critical transmission route. This cross-sectional study comprised a household survey with samples of child food (n = 382) and structured observations of food preparation (n = 197) among children aged 6-59 months that were discharged from treatment in community management of acute malnutrition (CMAM) programmes in South Sudan. We quantified Escherichia coli and total coliforms (TCs), measured in colony forming units per g of food (CFU/g), as indicators of microbial contamination of child food. A modified hazard analysis critical control point (HACCP) approach was utilised to determine critical control points (CCPs) followed by multivariate logistic regression analysis to understand the risk factors associated with contamination. Over 40% (n = 164) of samples were contaminated with E. coli (43% >0 E. coli CFU/g, 95% CI 38%-48%), and 90% (n = 343) had >10 TCs (CFU/g) (>10 TC CFU/g, 95% CI 87%-93%). Risk factors associated (p < 0.05) with child food contamination included if the child fed themselves (9.05 RR, 95% CI [3.18, 31.16]) and exposure to animals (2.63 RR, 95% CI [1.33, 5.34]). This study highlights the risk factors and potential control strategies that can support interventions that reduce food contamination exposure in young children and help further protect those that are highly vulnerable to recurrent exposure to enteric pathogens.

Impact of COVID-19 program adaptations on costs and cost-effectiveness of community management of acute malnutrition program in South Sudan.

OBJECTIVE: We assessed the impact of the COVID-19 pandemic and the protocol adaptations on cost and cost-effectiveness of community management of acute malnutrition (CMAM) program in South Sudan. DESIGN: Retrospective program expenditure-based analysis of non-governmental organisation (NGO) CMAM programs for COVID-19 period (April 2020-December 2021) in respect to pre-COVID period (January 2019-March 2020). SETTING: Study was conducted as part of a bigger evaluation study in South Sudan. PARTICIPANTS: International and national NGOs operating CMAM programs under the nutrition cluster participated in the study. RESULTS: The average cost per child recovered from the programme declined by 20 % during COVID from $133 (range: $34-1174) pre-COVID to $107 (range: $20-333) during COVID. The cost per child recovered was negatively correlated with programme size (pre-COVID r-squared = 0·58; during COIVD r-squared = 0·50). Programmes with higher enrollment were cheaper compared with those with low enrolment. Salaries, ready to use food and community activities accounted for over two-thirds of the cost per recovery during both pre-COVID (69 %) and COVID (79 %) periods. While cost per child recovered decreased during COVID period, it did not negatively impact on the programme outcome. Enrolment increased by an average of 19·8 % and recovery rate by 4·6 % during COVID period. CONCLUSIONS: Costs reduced with no apparent negative implication on recovery rates after implementing the COVID CMAM protocol adaptations with a strong negative correlation between cost and programme size. This suggests that investing in capacity, screening and referral at existing CMAM sites to enable expansion of caseload maybe a preferable strategy to increasing the number of CMAM sites in South Sudan.

A Prospective Comparison of Standard and Modified Acute Malnutrition Treatment Protocols during COVID-19 in South Sudan.

A non-randomized prospective cohort study was conducted in 2022 to compare recovery rate and length of stay (LoS) for acutely malnourished children treated under South Sudan's standard Community Management of Acute Malnutrition (CMAM) protocol and a COVID-modified protocol. Children aged 6-59 months received acute malnutrition (AM) treatment under the standard or modified protocol (mid-upper-arm circumference-only entry/exit criteria and simplified dosing). Primary (recovery rate and LoS) were compared for outpatient therapeutic (OTP) and therapeutic supplementary feeding programs (TSFP) using descriptive statistics and mixed-effects models. Children admitted to OTP under both protocols were similar in age and sex; children admitted to TSFP were significantly older under the modified protocol than the standard protocol. Shorter LoS and higher recovery rates were observed under the modified protocol for both OTP (recovery: 93.3% vs. 87.2%; LoS: 38.3 vs. 42.8 days) and TSFP (recovery: 79.8% vs. 72.7%; LoS: 54.0 vs. 61.9 days). After adjusting for site and child characteristics, neither differences in adjusted odds of recovery [OTP: 2.63; TSFP 1.80] nor LoS [OTP -10.0; TSFP -7.8] remained significant. Modified protocols for AM performed well. Adjusted models indicate similar treatment outcomes to the standard protocol. Adopting simplified protocols could be beneficial post-pandemic; however, recovery and relapse will need to be monitored.

Seasonal malaria chemoprevention in a context of high presumed sulfadoxine-pyrimethamine resistance: malaria morbidity and molecular drug resistance profiles in South Sudan.

BACKGROUND: Seasonal malaria chemoprevention (SMC) using sulfadoxine-pyrimethamine plus amodiaquine (SP-AQ), is a community-based malaria preventive strategy commonly used in the Sahel region of sub-Saharan Africa. However, to date it has not been implemented in East Africa due to high SP resistance levels. This paper is a report on the implementation of SMC outside of the Sahel in an environment with a high level of presumed SP-resistance: five cycles of SMC using SPAQ were administered to children 3-59 months during a period of high malaria transmission (July-December 2019) in 21 villages in South Sudan. METHODS: A population-based SMC coverage survey was combined with a longitudinal time series analysis of health facility and community health data measured after each SMC cycle. SMC campaign effectiveness was assessed by Poisson model. SPAQ molecular resistance markers were additionally analysed from dried blood spots from malaria confirmed patients. RESULTS: Incidence of uncomplicated malaria was reduced from 6.6 per 100 to an average of 3.2 per 100 after SMC administration (mean reduction: 53%) and incidence of severe malaria showed a reduction from 21 per 10,000 before SMC campaign to a mean of 3.3 per 10,000 after each cycle (mean reduction: 84%) in the target group when compared to before the SMC campaign. The most prevalent molecular haplotype associated with SP resistance was the IRNGE haplotype (quintuple mutant, with 51I/59R/108N mutation in pfdhfr + 437G/540E in pfdhps). In contrast, there was a low frequency of AQ resistance markers and haplotypes resistant to both drugs combined (< 2%). CONCLUSIONS: The SMC campaign was effective and could be used as an additional preventive tool in seasonal malaria settings outside of the Sahel, especially in areas where access to health care is unstable. Malaria case load reduction was observed despite the high level of resistance to SP.

Transmissibility and severity of COVID-19 in a humanitarian setting: First few X investigation of cases and contacts in Juba, South Sudan, 2020.

BACKGROUND: The first few 'X' (FFX) studies provide evidence to guide public health decision-making and resource allocation. The adapted WHO Unity FFX protocol for COVID-19 was implemented to gain an understanding of the clinical, epidemiological, virological and household transmission dynamics of the first cases of COVID-19 infection detected in Juba, South Sudan. METHODS: Laboratory-confirmed COVID-19 cases were identified through the national surveillance system, and an initial visit was conducted with eligible cases to identify all close contacts. Consenting cases and close contacts were enrolled between June 2020 and December 2020. Demographic, clinical information and biological samples were taken at enrollment and 14-21 days post-enrollment for all participants. RESULTS: Twenty-nine primary cases and 82 contacts were included in the analyses. Most primary cases (n = 23/29, 79.3%) and contacts (n = 61/82, 74.4%) were male. Many primary cases (n = 18/29, 62.1%) and contacts (n = 51/82, 62.2%) were seropositive for SARS-CoV-2 at baseline. The secondary attack rate among susceptible contacts was 12.9% (4/31; 95% CI: 4.9%-29.7%). All secondary cases and most (72%) primary cases were asymptomatic. Reported symptoms included coughing (n = 6/29, 20.7%), fever or history of fever (n = 4/29, 13.8%), headache (n = 3/29, 10.3%) and shortness of breath (n = 3/29, 10.3%). Of 38 cases, two were hospitalised (5.3%) and one died (2.6%). CONCLUSIONS: These findings were used to develop the South Sudanese Ministry of Health surveillance and contract tracing protocols, informing local COVID-19 case definitions, follow-up protocols and data management systems. This investigation demonstrates that rapid FFX implementation is critical in understanding the emerging disease and informing response priorities.

A circulating vaccine-derived poliovirus type 2 outbreak in a chronic conflict setting: a descriptive epidemiological study in South Sudan - 2020 to 2021.

BACKGROUND: In this study, we describe the epidemiological profile of an outbreak of the circulating Vaccine Derived Polio Virus type 2 in South Sudan from 2020 to 2021. METHOD: We conducted a retrospective descriptive epidemiological study using data from the national polio/AFP surveillance database, the outbreak investigation reports, and the vaccination coverage survey databases stored at the national level. RESULTS: Between September 2020 and April 2021, 59 cases of the circulating virus were confirmed in the country, with 50 cases in 2020 and 9 cases in 2021. More cases were males (56%) under five (93%). The median age of the cases was 23.4 ± 11.9 months, ranging from 1 to 84 months. All states, with 28 out of the 80 counties, reported at least one case. Most of the cases (44, 75%) were reported from five states, namely Warrap (31%), Western Bahr el Ghazal (12%), Unity (12%), Central Equatoria (10%), and Jonglei (10%). Four counties accounted for 45.8% of the cases; these are Gogrial West with 12 (20%), Jur River with 5 (8.5%), Tonj North with 5 (8.5%), and Juba with 5 (8.5%) cases. The immunization history of the confirmed cases indicated that 14 (24%) of the affected children had never received any doses of oral polio or injectable vaccines either from routine or during supplemental immunization before the onset of paralysis, 17 (28.8%) had received 1 to 2 doses, while 28 (47.5%) had received 3 or more doses (Fig. 4). Two immunization campaigns and a mop-up were conducted with monovalent Oral Polio Vaccine type 2 in response to the outbreak, with administrative coverage of 91.1%, 99.1%, and 97% for the first, second, and mop-up rounds, respectively. CONCLUSION: The emergence of the circulating vaccine-derived poliovirus outbreak in South Sudan was due to low population immunity, highlighting the need to improve the country's routine and polio immunization campaign coverage.

Bridging the humanitarian-development divide in a protracted crisis: a case study of the use of a central plant to supply oxygen for COVID-19 case management in South Sudan.

The rising demand for medicinal oxygen due to the COVID-19 pandemic exacerbated an underlying chronic shortage of the commodity in Africa. This situation is particularly dire in protracted crises where insecurity, dysfunctional health facilities, poor infrastructure and prohibitive costs hinder equitable access to the commodity. Against this backdrop, the Ministry of Health of South Sudan, with the guidance of its partners, procured and installed a pressure swing adsorption central oxygen supply plant to address the shortfall. The plant aimed to ensure a more sustainable and technologically appropriate medicinal oxygen supply system for the country and to bridge the humanitarian and development divide, which had always been challenging. This article discusses the key issues, challenges and lessons associated with the procurement and installation of this plant. The major challenges encountered during the procurement and installation of the plant were the time it took to procure and install in the face of urgent needs for medicinal oxygen and its short and long-term sustainability. Lessons learnt include the need for exhaustive and evidence-based considerations in deciding on which source of medicinal oxygen to deploy in protracted crisis settings. The successful installation and operationalization of the plant demonstrated that it is possible to bridge the humanitarian-development divide amidst the complexities of a protracted crisis and an ongoing pandemic. The Ministries of Health, with the support of its partners, should assess and document the impact of this and other similar central oxygen production plants in protracted crisis settings regarding their sustainability, cost, and effectiveness on medicinal oxygen supply. The Ministry of Health of South Sudan should expedite the finalization and operationalization of the longer-term public-private partnership and continue to monitor the quality of oxygen produced by this plant.
