RESUMO

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.

RESUMO

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.

RESUMO

The Ebola virus (EBOV) is still highly infectious and causes severe hemorrhagic fevers in primates. However, there are no regulatorily approved drugs against the Ebola virus disease (EVD). The highly virulent and lethal nature of EVD highlights the need to develop therapeutic agents. Viral protein 40 kDa (VP40), the most abundantly expressed protein during infection, coordinates the assembly, budding, and release of viral particles into the host cell. It also regulates viral transcription and RNA replication. This study sought to identify small molecules that could potentially inhibit the VP40 protein by targeting the N-terminal domain using an in silico approach. The statistical quality of AutoDock Vina's capacity to discriminate between inhibitors and decoys was determined, and an area under the curve of the receiver operating characteristic (AUC-ROC) curve of 0.791 was obtained. A total of 29,519 natural-product-derived compounds from Chinese and African sources as well as 2738 approved drugs were successfully screened against VP40. Using a threshold of -8 kcal/mol, a total of 7, 11, 163, and 30 compounds from the AfroDb, Northern African Natural Products Database (NANPDB), traditional Chinese medicine (TCM), and approved drugs libraries, respectively, were obtained after molecular docking. A biological activity prediction of the lead compounds suggested their potential antiviral properties. In addition, random-forest- and support-vector-machine-based algorithms predicted the compounds to be anti-Ebola with IC50 values in the micromolar range (less than 25 µM). A total of 42 natural-product-derived compounds were identified as potential EBOV inhibitors with desirable ADMET profiles, comprising 1, 2, and 39 compounds from NANPDB (2-hydroxyseneganolide), AfroDb (ZINC000034518176 and ZINC000095485942), and TCM, respectively. A total of 23 approved drugs, including doramectin, glecaprevir, velpatasvir, ledipasvir, avermectin B1, nafarelin acetate, danoprevir, eltrombopag, lanatoside C, and glycyrrhizin, among others, were also predicted to have potential anti-EBOV activity and can be further explored so that they may be repurposed for EVD treatment. Molecular dynamics simulations coupled with molecular mechanics Poisson-Boltzmann surface area calculations corroborated the stability and good binding affinities of the complexes (-46.97 to -118.9 kJ/mol). The potential lead compounds may have the potential to be developed as anti-EBOV drugs after experimental testing.

RESUMO

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.

RESUMO

Phosphatidylserine (PS) is a critical lipid factor in the assembly and spread of numerous lipid-enveloped viruses. Here, we describe the ability of the Ebola virus (EBOV) matrix protein eVP40 to induce clustering of PS and promote viral budding in vitro, as well as the ability of an FDA-approved drug, fendiline, to reduce PS clustering and subsequent virus budding and entry. To gain mechanistic insight into fendiline inhibition of EBOV replication, multiple in vitro assays were run including imaging, viral budding and viral entry assays. Fendiline lowers PS content in mammalian cells and PS in the plasma membrane, where the ability of VP40 to form new virus particles is greatly lower. Further, particles that form from fendiline-treated cells have altered particle morphology and cannot significantly infect/enter cells. These complementary studies reveal the mechanism by which EBOV matrix protein clusters PS to enhance viral assembly, budding, and spread from the host cell while also laying the groundwork for fundamental drug targeting strategies.

RESUMO

Three isopimarane diterpenes [fladins B (1), C (2), and D (3)] were isolated from the twigs and leaves of Chinese folk medicine, Isodon flavidus. The chemical structures were determined by the analysis of the comprehensive spectroscopic data, and the absolute configuration was confirmed by X-ray crystallographic analysis. The structures of 1-3 were formed from isopimaranes through the rearrangement of ring A by the bond break at C-3 and C-4 to form a new δ-lactone ring system between C-3 and C-9. This structure type represents the first discovery of a natural isopimarane diterpene with an unusual lactone moiety at C-9 and C-10. In the crystal of 1, molecules are linked to each other by intermolecular O-H···O bonds, forming chains along the b axis. Compounds 1-3 were evaluated for their bioactivities against different diseases. None of these compounds displayed cytotoxic activities against HCT116 and A549 cancer cell lines, antifungal activities against Trichophyton rubrum and T. mentagrophytes, or antiviral activities against HIV entry at 20 µg/mL (62.9-66.7) µM. Compounds 1 and 3 did not show antiviral activities against Ebola entry at 20 µg/mL either; only 2 was found to show an 81% inhibitory effect against Ebola entry activity at 20 µg/mL (66.7 µM). The bioactivity evidence suggested that this type of compound could be a valuable antiviral lead for further structure modification to improve the antiviral potential.

RESUMO

Objectives: This is a comparative cohort study aiming to evaluate the mortality risk factors for patients with nosocomial meningitis (NM) induced by multidrug-resistant Enterobacteriaceae (MDRE) in China. The clinical features and therapies of patients and the resistance mechanisms of MDRE pathogens were also assessed. Methods: MDRE-NM patients from two neurosurgical centers in China from 2014 to 2019 were included in this study. Clinical features were extracted from the medical record databases of the two centers. The molecular mechanisms underlying the microbiological resistance mechanisms of each MDRE pathogen were determined, Kaplan-Meier survival analysis was conducted, and multivariable analyses were performed using a Cox proportional hazard model. Results: Ninety MDRE-NM patients were included in this study. Klebsiella pneumoniae accounted for the highest proportion of causative pathogens (46/90, 51.1%), and 40 causative pathogens (44.4%) were meropenem-resistant. blaKPC (27/40, 67.5%) was the predominant carbapenem resistance gene. Multivariate Cox analysis showed that external ventricular drainage (EVD) [hazard ratio (HR) = 2.524, 95% confidence interval (CI) = 1.101-5.787, p = 0.029] and a Glasgow Coma Scale (GCS) score ≤;8 (HR = 4.033, 95% CI = 1.526-10.645, p = 0.005) were mortality risk factors for patients with MDRE-NM. A total of 90.0%, 94.4%, and 97.8% of MDRE-NM patients received antibiotic prophylaxis (AP), antibiotic empirical therapy (AET), and antibiotic definitive therapy (ADT), respectively. Conclusions: NM caused by MDRE is an important sign of the failure of neurosurgery. MDRE possesses multiple drug resistance genotypes, and EVD and a GCS score ≤;8 are independent mortality risk factors for patients with MDRE-NM, which deserve the attention of microbiologists and neurosurgical clinicians.

RESUMO

Ebola virus disease (EVD), a disease caused by infection with Ebola virus (EBOV), is characterized by hemorrhagic fever and a high case fatality rate. With limited options for the treatment of EVD, anti-Ebola viral therapeutics need to be urgently developed. In this study, over 500 extracts of medicinal plants collected in the Lingnan region were tested against infection with Ebola-virus-pseudotyped particles (EBOVpp), leading to the discovery of Maesa perlarius as an anti-EBOV plant lead. The methanol extract (MPBE) of the stems of this plant showed an inhibitory effect against EBOVpp, with an IC50 value of 0.52 µg/mL, which was confirmed by testing the extract against infectious EBOV in a biosafety level 4 laboratory. The bioassay-guided fractionation of MPBE resulted in three proanthocyanidins (procyanidin B2 (1), procyanidin C1 (2), and epicatechin-(4ß→8)-epicatechin-(4ß→8)-epicatechin-(4ß→8)-epicatechin (3)), along with two flavan-3-ols ((+)-catechin (4) and (-)-epicatechin (5)). The IC50 values of the compounds against pseudovirion-bearing EBOV-GP ranged from 0.83 to 36.0 µM, with 1 as the most potent inhibitor. The anti-EBOV activities of five synthetic derivatives together with six commercially available analogues, including EGCG ((-)-epigallocatechin-3-O-gallate (8)), were further investigated. Molecular docking analysis and binding affinity measurement suggested the EBOV glycoprotein could be a potential molecular target for 1 and its related compounds.

RESUMO

INTRODUCTION: According to the Centers for Disease Control and Prevention, Ebola has affected the lives of thousands, including health care workers. With few studies describing the experience of nurses who survived Ebola, the study aimed to describe Ugandan nurses' experiences. METHOD: Using a phenomenological design, in-depth interviews were conducted among five Ugandan nurses who contracted Ebola and survived. RESULT: Thematic analysis revealed themes of expectations of dying, hopelessness, loneliness, and betrayal by family, community, and the health system. DISCUSSION: Results support the need for policies targeting holistic practice protocols to protect all health care professionals during future outbreaks. Last, nursing survivors should have access to government-guaranteed support programs, including free health care and financial stipends. These results and recommendations transcend to the current reality of living with COVID-19 (coronavirus disease 2019). Efficient practice protocols could protect all rights and privileges and contribute to access to treatment and stigma removal.

RESUMO

Background: The Republic of Liberia has had major disruptions to the education of its health care cadres. Post Ebola, the Resilient and Responsive Health Systems (RRHS) initiative began a new era of capacity building with the support of PEPFAR and HRSA. Nursing and Midwifery serve as the largest healthcare cadres in Liberia. The national nursing and midwifery curricula were overdue for the regulated review and revisions. Methods: The Science of Improvement was used as the framework to accomplish this multilateral activity. The Institute for Healthcare Improvement's (IHI) stages of improvement included: 1) Forming the team, 2) Setting the aims, 3) Establishing measures, 4) Selecting measures, 5) Testing changes, 6) Implementing changes, and 7) Spreading changes. These stages served as the blueprint for the structures and processes put into place to accomplish this national activity. Findings: The RN, Bridging, and BScM curricula all had redundant content that did not reflect teaching pedagogy and health priorities in Liberia. Courses were eliminated or reconfigured and new courses were created. Development of Nursing and Midwifery Curricular Taskforces were not as successful as was hoped. Two large stakeholder meetings ensured that this was the curricula of the Liberian faculty, deans and directors, and clinical partners. Monitoring and evaluation tools have been adopted by the Liberian Board for Nursing and Midwifery to serve as another improvement to check that the new curricula are being implemented and to identify gaps that may require future cycles of change for continued quality and improvement. Conclusions: Developing trust among the multilateral partners was critical to the success of this activity. Networks have been expanded, and a proposed pilot with the Ghana Board of Nursing and Midwifery and the US academic partner will examine the feasibility of implementing electronic licensing examinations for nurses and midwives.

RESUMO

The unprecedented 2013-2016 West Africa Ebola outbreak accelerated several medical countermeasures (MCMs) against Ebola virus disease (EVD). Several investigational products (IPs) were used throughout the outbreak but were not conclusive for efficacy results. Only the Randomized Controlled Trial (RCT) on ZMapp was promising but inconclusive. More recently, during the second-largest Ebola outbreak in North Kivu and Ituri provinces, Democratic Republic of the Congo (DRC), four IPs, including one small molecule (Remdesivir), two monoclonal antibody (mAb) cocktails (ZMapp and REGN-EB3) and a single mAb (mAb114), were evaluated in an RCT, the Pamoja Tulinde Maisha (PALM) study. Two products (REGN-EB3 and mAb114) demonstrated efficacy as compared to the control arm, ZMapp. There were remarkably few side effects recorded in the trial. The FDA approved both medications in this scientifically sound study, marking a watershed moment in the field of EVD therapy. These products can be produced relatively inexpensively and can be stockpiled. The administration of mAbs in EVD patients appears to be safe and effective, while several critical knowledge gaps remain; the impact of early administration of Ebola-specific mAbs on developing a robust immune response for future Ebola virus exposure is unknown. The viral mutation escape, leading to resistance, presents a potential limitation for single mAb therapy; further improvements need to be explored. Understanding the contribution of Fc-mediated antibody functions such as antibody-dependent cellular cytotoxicity (ADCC) of those approved mAbs is still critical. The potential merit of combination therapy and post-exposure prophylaxis (PEP) need to be demonstrated. Furthermore, the PALM trial has accounted for 30% of mortality despite the administration of specific treatments. The putative role of EBOV soluble Glycoprotein (sGP) as a decoy to the immune system, the virus persistence, and relapses might be investigated for treatment failure. The development of pan-filovirus or pan-species mAbs remains essential for protection. The interaction between FDA-approved mAbs and vaccines remains unclear and needs to be investigated. In this review, we summarize the efficacy and safety results of the PALM study and review current research questions for the further development of mAbs in pre-exposure or emergency post-exposure use.

RESUMO

Combinatorial therapies that target multiple pathways have shown great promises for treating complex diseases. DrugComb (https://drugcomb.org/) is a web-based portal for the deposition and analysis of drug combination screening datasets. Since its first release, DrugComb has received continuous updates on the coverage of data resources, as well as on the functionality of the web server to improve the analysis, visualization and interpretation of drug combination screens. Here, we report significant updates of DrugComb, including: (i) manual curation and harmonization of more comprehensive drug combination and monotherapy screening data, not only for cancers but also for other diseases such as malaria and COVID-19; (ii) enhanced algorithms for assessing the sensitivity and synergy of drug combinations; (iii) network modelling tools to visualize the mechanisms of action of drugs or drug combinations for a given cancer sample and (iv) state-of-the-art machine learning models to predict drug combination sensitivity and synergy. These improvements have been provided with more user-friendly graphical interface and faster database infrastructure, which make DrugComb the most comprehensive web-based resources for the study of drug sensitivities for multiple diseases.

RESUMO

Health innovations are generally oriented on a techno-economic vision. In this perspective, technologies are seen as an end in themselves, and there is no arrangement between the technical and the social values of innovation. This vision prevails in sanitary crises, in which management is carried out based on the search for punctual, reactive, and technical solutions to remedy a specific problem without a systemic/holistic, sustainable, or proactive approach. This paper attempts to contribute to the literature on the epistemological orientation of innovations in the field of public health. Taking the Covid-19 and Ebola crises as examples, the primary objective is to show how innovation in health is oriented towards a techno-economic paradigm. Second, we propose a repositioning of public health innovation towards a social paradigm that will put more emphasis on the interaction between social and health dimensions in the perspective of social change. We will conclude by highlighting the roles that public health could play in allowing innovations to have more social value, especially during sanitary crises.

RESUMO

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.

RESUMO

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.

RESUMO

OBJECTIVE: To evaluate the inclusion and exclusion of nutritional content in guidance materials related to nutritional care for hospitalised Ebola Virus Disease (EVD) patients of any age with the aim to provide recommendations for future revised nutritional care guidelines in Ebola Treatment Units (ETU). DESIGN: Qualitative and quantitative analyses of ETU protocols and other guidance materials were conducted. Materials were obtained from practitioners, their organisations and governments active in EVD outbreaks since 2014. SETTING: Guinea, Liberia, Sierra Leone and Democratic Republic of Congo. RESULTS: Guidance materials showed a wide variety of topics. Most contained information on different feeding phases during illness, the use of specialised products, what and how to feed children aged 0-23 months, and meal and snack frequency for different age groups. Most materials lacked guidance on how to assess or accommodate patients' dietary preferences, how to obtain feedback on nutritional care from patients or how to assess whether patients need feeding support. These aspects are particularly relevant to prevent deterioration of the patients' nutritional status. There was limited guidance on operational aspects of food preparation and provision. CONCLUSIONS: Since 2014, numerous materials have been developed by organisations and governments on nutritional support in ETU. Although every EVD outbreak response must be contextualised because of the complexity of EVD and its case management, it is important to resolve technical differences and to provide comprehensive and more practical guidance. The findings of this study may inform future revised guidelines from normative UN organisations and governments of countries affected by EVD.

RESUMO

Frontline hospitals are at the forefront of all travel-related, emerging and reemerging infectious diseases and special pathogens. Yet, the readiness of frontline hospitals and their ability to identify, isolate, and inform on Ebola and other special pathogens is uncertain. This article addresses the resources necessary to support screening for Ebola and other special pathogens and presents the decision-making algorithm for the transport of patients with high-consequence infectious diseases within the New York City Health + Hospitals integrated healthcare delivery network, which includes 10 frontline hospitals and the Region 2 Ebola and Other Special Pathogen Treatment Center.

RESUMO

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.

RESUMO

BACKGROUND: The Covid-19 pandemic has caused fear and panic worldwide, forcing healthcare systems to disregard conventional practices and adopt innovation to contain the infection and death. Globally, there has been a rapid proliferation of research studies and clinical trials assessing risks, infectivity and treatment. METHODS: This review assesses the opportunities and challenges in the Middle East North Africa (MENA) region to engage in the conduct of high quality clinical trials during the Covid-19 pandemic. RESULTS: Opportunities are abundant for conducting clinical trials in MENA countries, including substantial cost savings, academic health centers, integrated health information systems, international accreditation, and international collaborations. Yet, the MENA region has missed out on opportunities to advance patient research during prior infectious disease outbreaks caused by the Severe Acute Respiratory Syndrome, Ebola, and the Middle East Respiratory Syndrome, as evidenced by the lack of concerted research and clinical trials from the region. A large vulnerable population, especially the poor expatriate work force, the current isolation of the health centers, and the lack of an expert network or field trained task force, all contribute to challenges preventing the formation of a pan Arab research enterprise for epidemics. CONCLUSION: Quality clinical research is critical during public health emergencies to identify treatments and solutions. The efficient conduct of clinical trials requires innovative strategies in research design, approval, and dissemination. Many countries in the MENA region have an opportunity to quickly ramp up research capacity and contribute significantly to the fight against the Covid-19 global threat.
