Impact of Ebola epidemics on the daily operation of existing systems in Eastern Democratic Republic of the Congo: a brief review.

AIMS: to provide insights into the recent Ebola virus disease (EVD) outbreaks on different aspects of daily life in the Democratic Republic of the Congo and propose possible solutions. METHODS: We collected information regarding the effects of EVD outbreaks on existing systems in the eastern part of the Democratic Republic of the Congo (DRC). We searched the PubMed database using the terms "impact effect Ebola outbreak system", "Management Ebola Poor Resources Settings", "Health Economic Challenges Ebola" and "Economic impact Ebola systems." Only studies focusing on epidemiology, diagnostics, sequencing, vaccination, therapeutics, ecology, work force, governance, healthcare provision and health system, and social, political, and economic aspects were considered. The search included the electronic archives of EVD outbreak reports from government and partners. RESULTS: EVD outbreaks negatively impacts the functions of countries. The disruption in activities is proportional to the magnitude of the epidemic and slows down the transport of goods, decreases the region's tourist appeal, and increases 'brain drain'. Most low- and medium-income countries, such as the DRC, do not have a long-term holistic emergency plan for unexpected situations or sufficient resources to adequately implement countermeasures against EVD outbreaks. Although the DRC has acquired sufficient expertise in diagnostics, genomic sequencing, administration of vaccines and therapeutics, clinical trials, and research activities, deployment, operation, and maintenance of these expertise and associated tools remains a concern. LIMITATIONS: Despite the data search extension, additional reports addressing issues related to social aspects of EVD outbreaks in DRC were not retrieved. CONCLUSION: National leadership has not yet taken the lead in strategic, operational, or financial aspects. Therefore, national leaders should double their efforts and awareness to encourage local fundraising, sufficient budget al.location, infrastructure construction, equipment provision, and staff training, to effectively support a holistic approach in response to outbreaks, providing effective results, and all types of research activities.

A community-based contact isolation strategy to reduce the spread of Ebola virus disease: an analysis of the 2018-2020 outbreak in the Democratic Republic of the Congo.

INTRODUCTION: Despite tremendous progress in the development of diagnostics, vaccines and therapeutics for Ebola virus disease (EVD), challenges remain in the implementation of holistic strategies to rapidly curtail outbreaks. We investigated the effectiveness of a community-based contact isolation strategy to limit the spread of the disease in the Democratic Republic of Congo (DRC). METHODS: We did a quasi-experimental comparison study. Eligible participants were EVD contacts registered from 12 June 2019 to 18 May 2020 in Beni and Mabalako Health Zones. Intervention group participants were isolated to specific community sites for the duration of their follow-up. Comparison group participants underwent contact tracing without isolation. The primary outcome was measured as the reproduction number (R) in the two groups. Secondary outcomes were the delay from symptom onset to isolation and case management, case fatality rate (CFR) and vaccination uptake. RESULTS: 27 324 EVD contacts were included in the study; 585 in the intervention group and 26 739 in the comparison group. The intervention group generated 32 confirmed cases (5.5%) in the first generation, while the comparison group generated 87 (0.3%). However, the 32 confirmed cases arising from the intervention contacts did not generate any additional transmission (R=0.00), whereas the 87 confirmed cases arising from the comparison group generated 99 secondary cases (R=1.14). The average delay between symptom onset and case isolation was shorter (1.3 vs 4.8 days; p<0.0001), CFR lower (12.5% vs 48.4%; p=0.0001) and postexposure vaccination uptake higher (86.0% vs 56.8%; p<0.0001) in the intervention group compared with the comparison group. A significant difference was also found between intervention and comparison groups in survival rate at the discharge of hospitalised confirmed patients (87.9% vs 47.7%, respectively; p=0.0004). CONCLUSION: The community-based contact isolation strategy used in DRC shows promise as a potentially effective approach for the rapid cessation of EVD transmission, highlighting the importance of rapidly implemented, community-oriented and trust-building control strategies.

Understanding Experience of Patients With Highly Infectious Diseases During Extended Isolation: A Design Perspective.

OBJECTIVES: This study aimed to develop a better understanding of the unique needs of patients with highly infectious diseases and their perceptions of being placed in isolation. We explore the subjective experiences of patients treated for Ebola in a biocontainment unit (BCU) and the healthcare personnel who cared for them. BACKGROUND: The 2014 Ebola outbreak and the COVID-19 pandemic have brought to focus some major challenges of caring for patients with serious infectious diseases. Previous studies on BCU design have looked at ways to prevent self- and cross-contamination, but very few have examined how the built environment can support an improved patient experience. METHOD: A qualitative study was conducted with four patients treated for Ebola and two critical care nurses who provided direct care to them at a single BCU in the U.S. Data were collected through in-depth semi-structured interviews to capture the actual patients' perception and experience of isolation. The interviews were analyzed using the thematic analysis approach. RESULTS: The Ebola patients placed in source isolation perceived the BCU as an artificial environment where they lacked control, agency, autonomy, and independence. The physical separation from other patients, visitor restrictions, and staff wearing PPE contributed to feelings of social and emotional isolation, and loneliness. CONCLUSIONS: The isolation can take a toll on physiological and psychological well-being. A thoughtful design of isolation units may improve patients' experience by supporting human and social interactions, empowering patients through space flexibility and personalization of space, and supporting a more holistic approach to isolation care.

The Impact of Water Sanitation and Hygiene (WASH) Improvements on Hand Hygiene at Two Liberian Hospitals during the Recovery Phase of an Ebola Epidemic.

Fourteen years of civil war left Liberia with crumbling infrastructure and one of the weakest health systems in the world. The 2014-2015 Ebola virus disease (EVD) outbreak exposed the vulnerabilities of the Liberian health system. Findings from the EVD outbreak highlighted the lack of infection prevention and control (IPC) practices, exacerbated by a lack of essential services such as water, sanitation, and hygiene (WASH) in healthcare facilities. The objective of this intervention was to improve IPC practice through comprehensive WASH renovations conducted at two hospitals in Liberia, prioritized by the Ministry of Health (MOH). The completion of renovations was tracked along with the impact of improvements on hand hygiene (HH) practice audits of healthcare workers pre- and post-intervention. An occurrence of overall HH practice was defined as the healthcare worker practicing compliant HH before and after the care for a single patient encounter. Liberia Government Hospital Bomi (LGH Bomi) and St. Timothy Government Hospital (St. Timothy) achieved World Health Organization (WHO) minimum global standards for environmental health in healthcare facilities as well as Liberian national standards. Healthcare worker (HCW) overall hand hygiene compliance improved from 36% (2016) to 89% (2018) at LGH Bomi hospital and from 86% (2016) to 88% (2018) at St. Timothy hospital. Improved WASH services and IPC practices in resource-limited healthcare settings are possible if significant holistic WASH infrastructure investments are made in these settings.

Assessing the determinants of Ebola virus disease transmission in Baka Community of the Tropical Rainforest of Cameroon.

BACKGROUND: Ebola virus disease (EVD) is a severe, often fatal illness in humans and nonhuman primates caused by the Ebola virus. The recently approved rVSV-EBOV vaccine is not available in many high-risk countries hence prevention is paramount. The design of effective prevention interventions requires an understanding of the factors that expose communities at risk. It was based on this that we investigated the Baka community of Abong-Mbang Health District in tropical rain forest of Cameroon. METHODS: A cross-sectional study was conducted with participants randomly selected from 13 villages in Abong-Mbang by multi-stage cluster sampling. A questionnaire was administered to them to collect demographic information, data on knowledge of EVD, their feeding and health-seeking behaviour. Data was analyzed using the chi-square test. Knowledge of EVD was assessed using an 8 item Morisky Scale. An adapted Threat Capability Basic Risk Assessment Guide was used to determine their risk of exposure to infection. RESULTS: A total of 510 participants, most of whom were hunters (31.4%), farmers (29.8%), and had primary education (62.7%), were included in this study. Although 83.3% participants had heard of EVD, most (71%) did not know its cause. Their source of information was mainly informal discussions in the community (49%). Misconceptions were identified with regards to the cause and mode of transmission. Only 43.1% accepted EVD could be transmitted from human-to-human. Generally, participants' knowledge of EVD was poor. Demographic factors such as level of education, occupation and ethnic group significantly affected knowledge of EVD. The majority of participants were at a very high risk of exposure to infection as they consumed various forms of bush meat and were involved in other risky practices such as scarification and touching of corpses. Although over half of participants seek medical care, most of them preferred traditional medicine. Socio-cultural and service-related factors were deterrent factors to medical care. CONCLUSION: Participants generally had poor knowledge of EVD and were at high risk of infection. We recommend rigorous sensitization campaigns in the study area to educate the population on EVD and clarify the misconceptions identified. EVD surveillance is recommended particularly as outbreaks have often been reported in the Congo Basin.

One novel virus, different beliefs as playmakers towards disease spread in Africa: looking at COVID-19 from a religious lens.

Religious and spiritual observances that draw large people together are pervasive in many parts of the world, including Africa. With the recent emergence of COVID-19, these mass religious gatherings may pose significant threats to human health. Given the compromised healthcare systems in many parts of Africa, faith-based institutions have a huge responsibility towards the management of the potential spread of the virus through effective organizational strategies or interventions. This essay sheds light on what the novel virus has to do with religion, the role of religious practices in inhibiting or spreading COVID-19, and what appropriate evidence-based interventions religious or faith-based organizations could adopt to help prevent the spread of the disease in Africa through a unity of thoughts for religious action.

What Should Health Science Journalists Do in Epidemic Responses?

Journalists have long covered outbreaks of infectious disease. In the history of global health journalism-from the 1721 Boston smallpox epidemic to the 2002-2003 SARS outbreak in China and Singapore and to recent outbreaks of Ebola in West Africa and the Democratic Republic of the Congo-newsrooms have wielded their power both responsibly and irresponsibly. This article examines journalism practice during the 2013-2016 Ebola epidemic and recommends strategies for improving epidemic reporting.

Nutritional Care for Patients with Ebola Virus Disease.

During the Ebola virus disease (EVD) outbreak of 2014-2016 in West Africa, practitioners faced challenges providing nutritional care for patients in Ebola treatment units (ETUs). The current EVD outbreak in the Democratic Republic of the Congo demonstrates the need to understand lessons learned from previous outbreaks and to update nutritional guidelines. We conducted a literature review to identify articles that included nutrition as an integral part of supportive care. We found little information on the specific nutritional care or practical challenges within an ETU. This review showed that nutritional care for EVD patients is poorly described, and therefore the optimal composition and implementation of nutritional care remain unknown. We recommend that researchers and practitioners share specific and practical details of their experiences in providing nutritional support within ETUs to expand the knowledge base and ultimately improve the nutritional care for an increasingly prevalent patient population.

'The cat that kills people:' community beliefs about Ebola origins and implications for disease control in Eastern Democratic Republic of the Congo.

The current Ebola epidemic in Eastern Democratic Republic of Congo (DRC) has surpassed 1 700 deaths. Social resistance, a major barrier to control efforts, invites exploration of community beliefs around Ebola and its origins. We conducted a mixed-methods study, using four focus group discussions (FGDs) involving 20 participants, and a 19-item survey questionnaire, administered to a nonprobability sample of 286 community members throughout the outbreak zone. FGDs and surveys were conducted between 4 and 17 August 2018. FGDs revealed a widespread rumor early in the epidemic of two twins bewitched by their aunt after eating her cat, who developed bleeding symptoms and triggered the epidemic. However, this myth appeared to dissipate as the epidemic progressed and biomedical transmission became generally accepted. In our survey, 6% of respondents endorsed supernatural origins of Ebola. These respondents were more likely to believe that traditional medicine practitioners can cure Ebola. Wild animals were recognized as sources of Ebola by 53% and FGD participants commented that 'Ebola leaves the forest and hides in the hospital,' recognizing that zoonotic origins gave way to nosocomial transmission as the epidemic progressed. Taken together, our findings suggest that a dynamic syncretism of mythical and biomedical understanding of Ebola may have shaped transmission patterns. Mythical conceptions and fear of contagion may have fueled the 'underground' transmission of Ebola, as patients sought care from traditional healers, who are ill-equipped to deal with a highly contagious biohazard. A deeper understanding of beliefs around Ebola origins may illuminate strategies to engage communities in control efforts.

Marginalisation, Ebola and Health for All: From Outbreak to Lessons Learned.

The Ebola epidemic in West Africa between 2014 and 2015 was the deadliest since the discovery of the virus four decades ago. With the second-largest outbreak of Ebola virus disease currently raging in the Democratic Republic of the Congo, (DRC) it is clear that lessons from the past can be quickly forgotten-or be incomplete in the first instance. In this article, we seek to understand the health challenges facing marginalised people by elaborating on the multiple dimensions of marginalisation in the case of the West Africa Ebola epidemic. We trace and unpack modes of marginalisation, beginning with the "outbreak narrative" and its main components and go on to examine other framings, including the prioritisation of the present over the past, the positioning of 'Us versus Them'; and the marginalisation-in responses to the outbreak-of traditional medicine, cultural practices and other practices around farming and hunting. Finally, we reflect on the 'lessons learned' framing, highlighting what is included and what is left out. In conclusion, we stress the need to acknowledge-and be responsive to-the ethical, normative framings of such marginalisation.

Never again? Challenges in transforming the health workforce landscape in post-Ebola West Africa.

BACKGROUND: The 2013-2014 West African Ebola outbreak highlighted how the world's weakest health systems threaten global health security and heralded huge support for their recovery. All three Ebola-affected countries had large shortfalls and maldistribution in their health workforce before the crisis, which were made worse by the epidemic. This paper analyzes the investment plans in Liberia, Sierra Leone, and Guinea to strengthen their health workforces and assesses their potential contribution to the re-establishment and strengthening of their health systems. The analysis calculates the plans' costs and compares those to likely fiscal space, to assess feasibility. METHODS: Public sector payroll data from 2015 from each country was used for the workforce analysis and does not include the private sector. Data were coded into the major cadres defined by the International Standard Classification of Occupations (ISCO-88). We estimated health worker training numbers and costs to meet international health worker density targets in the future and used sensitivity analysis to model hypothetical alternate estimates of attrition, drop-outs, and employment rates. RESULTS: Health worker-to-population density targets per 1000 population for doctors, nurses, and midwives are only specified in Liberia (1.12) and Guinea's (0.78) investment plans and fall far short of the regional average for Africa (1.33) or international benchmarks of 2.5 per 1000 population and 4.45 for universal health coverage. Even these modest targets translate into substantial scaling-up requirements with Liberia having to almost double, Guinea quadruple, and Sierra Leone having to increase its workforce by seven to tenfold to achieve Liberia and Guinea's targets. Costs per capita to meet the 2.5 per 1000 population density targets with 5% attrition, 10% drop-out, and 75% employment rate range from US$4.2 in Guinea to US$7.9 in Liberia in 2029, with projected fiscal space being adequate to accommodate the proposed scaling-up targets in both countries. CONCLUSIONS: Achieving even a modest scale-up of health workforce will require a steady growth in health budgets, a long-term horizon and substantial scale-up of current training institution capacity. Increasing value-for-money in health workforce investments will require more efficient geographical distribution of the health workforce and more consideration to the mix of cadres to be scaled-up.

Ebola Therapeutic Study and Future Directions.

The constant Ebola epidemic outbreaks in Africa arisen in waves of panic worldwide. There is a high mortality rate (30-70%) among the Ebola-infected people in virus- stricken areas. Despite these horrors, the medical capabilities against this deadly viral disease were provided by limited therapeutic agents/options. As a result, several patented agents, biotherapies or prophylactic/therapeutic vaccines need to be reviving into the global markets-including patents of small molecular chemicals, short sequences or oligomers of DNA/RNA, linkages of chemicals with bio-molecules, herbal medicine and so on. In addition, the possible mechanisms of action of these therapeutic options are underway. To promote Ebola biomedical study, the multiple characters of Ebola infections-its origin, pathologic progress, genomic changes, therapeutic context and economic considerations are outlined in this review. Finally, a great difference can be expected after these types of efforts.

Community health workers during the Ebola outbreak in Guinea, Liberia, and Sierra Leone.

BACKGROUND: The role of community health workers (CHWs) in the West Africa Ebola outbreak has been highlighted to advocate for increasing numbers of CHWs globally to build resilience, strengthen health systems, and provide emergency response capacity. However, the roles CHWs played, the challenges they faced, and their effectiveness during the outbreak are not well documented. This study assessed the impact of Ebola on community-based maternal, newborn, and child health (MNCH) services, documented the contribution of CHWs and other community-based actors to the Ebola response, and identified lessons learned to strengthen resilience in future emergencies. METHODS: This mixed methods study was conducted in Guinea, Liberia, and Sierra Leone, with data collected in four Ebola-affected districts of each country. Qualitative data were collected through in-depth interviews and focus group discussions with stakeholders at national, district, and community levels. Quantitative program data were used to assess trends in delivery of community-based MNCH services. RESULTS: There was a sharp decline in MNCH service provision due to weak service delivery, confusion over policy, and the overwhelming nature of the outbreak. However, many CHWs remained active in their communities and were willing to continue providing services. When CHWs received clear directives and were supported, service provision rebounded. Although CHWs faced mistrust and hostility from community members because of their linkages to health facilities, the relationship between CHWs and communities proved resilient over time, and CHWs were more effectively able to carry out Ebola-related activities than outsiders. Traditional birth attendants, community health committees, community leaders, and traditional healers also played important roles, despite a lack of formal engagement or support. Service delivery weaknesses, especially related to supply chain and supervision, limited the effectiveness of community health services before, during, and after the outbreak. CONCLUSIONS: CHWs and other community-level actors played important roles during the Ebola outbreak. However, maintenance of primary care services and the Ebola response were hampered because community actors were engaged late in the response and did not receive sufficient support. In the future, communities should be placed at the forefront of emergency preparedness and response plans and they must be adequately supported to strengthen service delivery.

Lessons learned from Ebola Vaccine R&D during a public health emergency.

In spite of a complete lack of Research and Development (R&D) preparedness, the 2013-2016 West-Africa Ebola experience demonstrated that it is possible to compress R&D timelines to less than a single year, from a more usual decade or longer. This is mostly to be credited to an unprecedented collaborative effort building on the availability of a small number of candidate diagnostic tests, drugs and vaccines that could be moved rapidly into the clinical phase evaluation. The World Health Organization (WHO) led international consultations and activities - including the organization of a successful Ebola vaccine efficacy trial in Guinea - as a contribution to the unprecedented global efforts to control the Ebola epidemic. Since 2015, WHO expert teams and partners are implementing a novel R&D model for emerging infectious pathogens which are the most likely to cause severe outbreaks in the future, and for which no or only few medical countermeasures are available: the WHO R&D Blueprint. The objective for the Blueprint is the fostering of a R&D environment which is prepared for quickly and effectively responding to outbreaks due to emerging infectious disease.

Experiences of Ebola Survivors: Causes of Distress and Sources of Resilience.

Introduction An appreciation of the experience of Ebola survivors is critical for community engagement and an effective outbreak response. Few qualitative, descriptive studies have been conducted to date that concentrate on the voices of Ebola survivors. Problem This study aimed to explore the experiences of Ebola survivors following the West African epidemic of 2014. METHOD: An interpretive, qualitative design was selected using semi-structured interviews as the method of data collection. Data were collected in August 2015 by Médecins Sans Frontières (MSF) Belgium, for the purposes of internal evaluation. Data collection occurred at three sites in Liberia and Sierra Leone and involved 25 participants who had recovered from Ebola. Verbal consent was obtained, audio recordings were de-identified, and ethics approval was provided by Monash University (Melbourne, Australia). Findings Two major themes emerged from the study: "causes of distress" and "sources of resilience." Two further sub-themes were identified from each major theme: the "multiplicity of death," "abandonment," "self and community protection and care," and "coping resources and activities." The two major themes were dominant across all three sample groups, though each survivor experienced infection, treatment, and recovery differently. CONCLUSIONS: By identifying and mobilizing the inherent capacity of communities and acknowledging the importance of incorporating the social model of health into culturally competent outbreak responses, there is an opportunity to transcend the victimization effect of Ebola and empower communities, ultimately strengthening the response.

Ethnomedical and ethnobotanical investigations on the response capacities of Guinean traditional health practioners in the management of outbreaks of infectious diseases: The case of the Ebola virus epidemic.

ETHNOPHARMACOLOGICAL RELEVANCE: The recent outbreak of Ebola virus infections has mostly remained confined to the West African countries Guinea-Conakry, Sierra-Leone and Liberia. Due to intense national and international mobilizations, a significant reduction in Ebola virus transmission has been recorded. While international efforts focus on new vaccines, medicines and diagnostics, no coherent national or international approach exists to integrate the potential of the traditional health practitioners (THPs) in the management of infectious diseases epidemics. Nevertheless, the first contact of most of the Ebola infected patients is with the THPs since the symptoms are similar to those of common traditionally treated diseases or symptoms such as malaria, hemorrhagic syndrome, typhoid or other gastrointestinal diseases, fever and vomiting. MATERIALS AND METHODS: In an ethnomedical survey conducted in the 4 main Guinean regions contacts were established with a total of 113 THPs. The socio-demographic characteristics, the professional status and the traditional perception of Ebola Virus Disease (EVD) were recorded. RESULTS: The traditional treatment of the main symptoms was based on 47 vegetal recipes which were focused on the treatment of diarrhea (22 recipes), fever (22 recipes), vomiting (2 recipes), external antiseptic (2 recipes), hemorrhagic syndrome (2 recipes), convulsion and dysentery (one recipe each). An ethnobotanical survey led to the collection of 54 plant species from which 44 identified belonging to 26 families. The most represented families were Euphorbiaceae, Caesalpiniaceae and Rubiaceae. Literature data on the twelve most cited plant species tends to corroborate their traditional use and to highlight their pharmacological potential. CONCLUSIONS: It is worth to document all available knowledge on the traditional management of EVD-like symptoms in order to evaluate systematically the anti-Ebola potential of Guinean plant species.

Responses to spread of.Ebola virus disease epidemic in West Africa: A review.

BACKGROUND: The first Ebola virus disease (EVD) epidemic in West Africa is unprecedented in its spread, complexity and severity. Comparing responses to spread of the virus in the three most affected countries - Guinea, Sierra Leone and Liberia- with that in Nigeria, Senegal and Mali where the epidemic was quickly brought under control may guide future mitigation efforts. METHODS: Literature from Pubmed. Google,Center for Disease Control and Prevention (CDC), Morbidity and Mortality Weekly Report (MMWR), World Health Organization's Updates and Ebola Response Reports: Results: The epidemic spread undiagnosed for three months from Meliandou in Guinea to its four rural prefectures and its. capital Conakry, two countires in Liberia and two districts in Sierra Leone. Control measures were hampered by traditional and faith healers offering -inappropriate treatments, as well as secret societies encouraging unsafe burial rituals. Whereas, in Nigeria, a case imported from Liberia on 20 July 2014 was diagnosed on the 3rd day; all primary, secondary and tertiary contacts were traced. Also, at a formal meeting, officials of Lagos state government discouraged treatment of EVD by faith healers. In Senegal, a single case imported from Guinea on 20 August 2014 was diagnosed on the 9th day, treated and further spread was prevented. In Mali, there were two waves of transmissions identified on 23 October and 12 November 2014 within 15 days of importation and the epidemic was controlled.There were no cases of EVD treated by any traditional healers or faith healers in Nigeria, Senegal and Mali. CONCLUSION: Education of traditional and faith healers on EVD will complement control measures for EVD epidemic.
