Mathematical modelling approach of the study of Ebola virus disease transmission dynamics in a developing country

Background: Ebola Virus causes disease both in human and non-human primatesespecially in developing countries. In 2014 during its outbreak, it led to majority of deaths especially in some impoverished area of West Africa and its effect is still witnessed up till date. Materials and Methods:We studied the spread of Ebola virus and obtained a system of equations comprising of eighteen equations which completely described the transmission of Ebola Virus ina population where control measures were incorporated and a major source of contacting the disease which is the traditional washing of dead bodies was also incorporated. We investigated the local stability of the disease-free equilibrium using the Jacobian Matrix approach and the disease-endemic stability using the center manifold theorem. We also investigated the global stability of the equilibrium points using the LaSalle's Invariant principle.Results: The result showed that the disease-free and endemic equilibrium where both local and globally stable and that the system exhibits a forward bifurcation.Conclusions: Numerical simulations were carried out and our graphs show that vaccine and condom use is best for susceptible population, quarantine is best for exposed population, isolation is best for infectious population and proper burial of the diseased dead is the best to avoid further disease spread in the population and have quicker and better recovery.

Ebola outbreak in Guinea, 2021: Clinical care of patients with Ebola virus disease

Background: Experience from the Zaire Ebolavirus epidemic in the eastern Democratic Republic of the Congo (2018­2020) demonstrates that early initiation of essential critical care and administration of Zaire Ebolavirus specific monoclonal antibodies may be associated with improved outcomes among patients with Ebola virus disease (EVD). Objectives: This series describes 13 EVD patients and 276 patients with suspected EVD treated during a Zaire Ebolavirus outbreak in Guinea in 2021. Method: Patients with confirmed or suspected EVD were treated in two Ebola treatment centres (ETC) in the region of N'zérékoré. Data were reviewed from all patients with suspected or confirmed EVD hospitalised in these two ETCs during the outbreak (14 February 2021 ­ 19 June 2021). Ebola-specific monoclonal antibodies, were available 2 weeks after onset of the outbreak. Results: Nine of the 13 EVD patients (age range: 22­70 years) survived. The four EVD patients who died, including one pregnant woman, presented with multi-organ dysfunction and died within 48 h of admission. All eight patients who received Ebola-specific monoclonal antibodies survived. Four of the 13 EVD patients were health workers. Improvement of ETC design facilitated implementation of WHO-recommended 'optimized supportive care for EVD'. In this context, pragmatic clinical training was integrated in routine ETC activities. Initial clinical manifestations of 13 confirmed EVD patients were similar to those of 276 patients with suspected, but subsequently non confirmed EVD. These patients suffered from other acute infections (e.g. malaria in 183 of 276 patients; 66%). Five of the 276 patients with suspected EVD died. One of these five patients had Lassa virus disease and a coronavirus disease 2019 (COVID-19) co-infection. Conclusion: Multidisciplinary outbreak response teams can rapidly optimise ETC design. Trained clinical teams can provide WHO-recommended optimised supportive care, including safe administration of Ebola-specific monoclonal antibodies. Pragmatic training in essential critical care can be integrated in routine ETC activities. Contribution: This article describes clinical realities associated with implementation of WHO-recommended standards of 'optimized supportive care' and administration of Ebola virus specific treatments. In this context, the importance of essential design principles of ETCs is underlined, which allow continuous visual contact and verbal interaction of health workers and families with their patients. Elements that may contribute to further quality of care improvements for patients with confirmed or suspected EVD are discussed.

Points of entry dynamics: understanding the cross-border threats for Ebola virus disease and COVID-19 in Ghana using a logic model approach

Background. The influx of people across the national borders of Ghana has been of interest and concern in the public health and national security community in recent times due to the low capacity for the prevention and management of epidemics and other public health risks. Although the International Health Regulations (IHR) stipulate core public health capacities for designated border facilities such as international airports, seaports, and ground crossings, contextual factors that influence the attainment of effective public health measures and response capabilities remain understudied. Objective. To assess the relationship between contextual factors and COVID-19 procurement to help strengthen infrastructure resources for points of entry (PoE) public health surveillance functions, thereby eliminating gaps in the design, implementation, monitoring, and evaluation of pandemicrelated interventions in Ghana. Materials and Methods. This study employed a mixed-methods design, where quantitative variables were examined for relationships and effect size interactions using multiple linear regression techniques and the wild bootstrap technique. Country-level data was sourced from multiple publicly available sources using the social-ecological framework, logic model, and IHR capacity monitoring framework. The qualitative portion included triangulation with an expert panel to determine areas of convergence and divergence. Results. The most general findings were that laboratory capacity and KIA testing center positively predicted COVID-19 procurement, and public health response and airline boarding rule negatively predicted COVID-19 procurement. Conclusion. Contextual understanding of the COVID-19 pandemic and Ebola epidemic is vital for strengthening PoE mitigation measures and preventing disease importation.

Global Epidemic of Ebola Virus Disease and the Importation Risk into China: An Assessment Based on the Risk Matrix Method / 生物医学与环境科学（英文）

OBJECTIVE@#To analyze the global epidemic status of the Ebola virus disease (EVD) and assess the importation risk into China.@*METHODS@#Data from World Health Organization reports were used. We described the global epidemic status of EVD from 1976-2021, and assessed and ranked the importation risk of EVD from the disease-outbreaking countries into China using the risk matrix and Borda count methods, respectively.@*RESULTS@#From 1976-2021, EVD mainly occurred in western and central Africa, with the highest cumulative number of cases (14,124 cases) in Sierra Leone, and the highest cumulative fatality rate (85%) in the Congo. Outbreaks of EVD have occurred in the Democratic Republic of the Congo and Guinea since 2018. The importation risk into China varies across countries with outbreaks of disease. The Democratic Republic of the Congo had an extremely high risk (23 Borda points), followed by Guinea and Liberia. Countries with a moderate importation risk were Nigeria, Uganda, Congo, Sierra Leone, Mali, and Gabon, while countries with a low importation risk included Sudan, Senegal, and Co

Support for the response to COVID-19 in Uganda: contribution of the global health security program at Makerere University's Infectious Diseases Institute

Background: Outbreaks are occurring at increasing frequency and they require multisectoral and multi-stakeholder involvement for optimal response. The Global Health Security Agenda is a framework that governments and other stakeholders can use to strengthen countries' capacities to prevent, detect and respond to outbreaks but there are few examples of academic programs using this approach. Methods: This is a narrative review of contributions of Makerere University through the Global Health Security Program at the Infectious Diseases Institute (IDI). Information was sourced from peer-reviewed publications and grey literature highlighting work done between 2017 - 2021. Results: Aligned to GHSA, IDI made contributions to strengthen national and subnational capacities for biosafety and biosecurity, sample collection and transportation, electronic disease surveillance, infection prevention and control, case management prior to COVID-19 that were subsequently used to support response efforts for COVID-19 in Uganda. Conclusion: The IDI Global Health Security program provides a model that can be used by institutions to deliberately develop capacities relevant to outbreak preparedness and response.

Dixième épidémie d'Ebola en République Démocratique du Congo: défis majeurs relevés dans la prise en charge médicale / Tenth Ebola outbreak in Democratic Republic of the Congo: major challenges in health care management

Identifié depuis 1976, le filovirus Ebola est la cause d´une maladie caractérisée principalement par un syndrome grippale inaugural avec une fièvre quasi permanente suivi des signes digestifs: diarrhée, vomissement à la base de la déshydratation. La mort survient souvent dans un tableau de défaillance multi-viscérale (insuffisance hépatorénale, encéphalopathie voire, trouble de coagulation). Le taux de mortalité est compris entre 50 et 90%. Traditionnellement, les malades suspects et confirmés à Ebola étaient isolés dans des tentes pour un traitement essentiellement symptomatique avec utilisation fort limitée des actes invasifs. Les mesures de prévention n´étaient faites que de respect des mesures d´hygiène. Chez les personnels soignants, le taux de contamination était de 76% lors de la première épidémie de Yambuku. Au fil du temps, des mesures de prise en charge se sont améliorées par l´utilisation du vaccin, une réanimation appropriée, traitement spécifique au filovirus et l´utilisation des CUBE (chambre d´urgence biosécurisée pour epidémie).

Identified in 1976, Ebola virus, a member of the Filoviridae family (filovirus), can cause a disease mainly characterized by inaugural influenza-like syndrome with almost permanent fever followed by gastrointestinal symptoms, such as diarrhea, vomiting causing dehydration. Death often occurs as a result of multi-system organ failure (hepatorenal failure, encephalopathy or even blood clotting disorders). Mortality rate is between 50 and 90%. Traditionally, patients with suspected and diagnosed Ebola were isolated in tents for essentially symptomatic treatment with very limited use of invasive procedures. Prevention consisted of measures aimed at respecting hygiene. Among caregivers,infection rate was 76% during the first Yambuku outbreak. Over time, management measures have been improved by the use of the vaccine, appropriate resuscitation techniques, specific treatment for filovirus and the use of BECUO (Biosecure Emergency Care Unit for Outbreaks).

Conclusions: Survival was high, despite the complications presented. The symptoms and predictive signs of death in the patients were: the severity of the patient at admission, the presence of low back pain, headache, fever, abdominal pain and conjunctival injection(AU)

Historical epidemiology and global health history / Epidemiologia histórica e história global da saúde

Abstract The subdiscipline of historical epidemiology holds the promise of creating a more robust and more nuanced foundation for global public health decision-making by deepening the empirical record from which we draw lessons about past interventions. This essay draws upon historical epidemiological research on three global public health campaigns to illustrate this promise: the Rockefeller Foundation's efforts to control hookworm disease (1909-c.1930), the World Health Organization's pilot projects for malaria eradication in tropical Africa (1950s-1960s), and the international efforts to shut down the transmission of Ebola virus disease during outbreaks in tropical Africa (1974-2019).

Resumo A subdisciplina epidemiologia histórica se propõe a criar um alicerce robusto e refinado para o processo de tomada de decisões em saúde pública global, aprofundando registros empíricos que nos ensinam sobre intervenções passadas. Este artigo se baseia na pesquisa epidemiológica histórica de três campanhas globais de saúde pública para ilustrar essa proposta: os esforços da Fundação Rockefeller para controle da ancilostomose (1909-c.1930), os projetos-piloto da Organização Mundial da Saúde para erradicação da malária na África tropical (décadas de 1950-1960), e os esforços internacionais de interrupção da transmissão do vírus Ebola durante surtos na África tropical (1974-2019).

Ante el escaso número de estudios en este ámbito, el objetivo es analizar el contenido visual en la prensa durante la crisis sanitaria del Ébola en España que ocasionó gran alarma en la sociedad en 2014. En una muestra nacional de diarios, se identifica contenido visual en el 92% (n=160) de artículos sobre el Ébola y en el 87,5% (n=14) de portadas. La fotografía es el recurso más usado (69,2%), seguido de gráficos (9,2%) e infografías (8,8%), mientras que 'conflicto' es el encuadre más frecuente (42%). Se detecta un aumento rápido del contenido visual en los primeros dos días de la crisis que disminuye paulatinamente a partir del quinto día (p<.001). Este estudio puede abrir nuevas vías de investigación para profundizar en la investigación del contenido visual, especialmente durante la crisis sanitaria dada la gran importancia que adquiere la comunicación.(AU)

Considering the scarce number of studies in this sphere, the objective is to analyze the visual content published by the press during the health crisis of Ebola in Spain, which caused great alarm in that society in 2014. In a sample of Spanish newspapers, visual content was identified in 92% (n=160) of the articles about Ebola and in 87.5% (n=14) of front pages. Photography was the most used resource (69.2%), followed by graphs (9.2%) and infographics (8.8%), while 'conflict' was the most frequent framing (42%). A rapid increase in the use of visual content was detected in the first two days of the crisis, followed by a gradual decrease from the fifth day onwards (p <0.001). This study can open new research paths for further investigation of visual content, especially during a health crisis, due to the great importance communication acquires in this situation.(AU)

Ebola virus disease preparedness in countries bordering Democratic Republic of Congo: lessons from west African outbreak: Ebola virus disease preparedness

Background: Ebola virus disease ravaged three West African countries in the wake of 2014 which was seen as the deadliest Ebola Virus Disease (EVD) outbreak in history. Several lessons were taken out of the West African outbreak one of which is the lack of preparedness by countries in the region.Materials and Methods: This paper looked at the mistakes of the West African outbreak and reports how such mistakes were corrected in the current outbreak going on in the Democratic Republic of Congo (DRC). Preparedness efforts are currently taking place in countries bordering DRC which included quick detection and response to an eventual EVD event.Results: This paid off on several occasions when cases from DRC to Uganda were quickly detected and response was as quick as possible. Preparedness carried out in Countries bordering DRC included setting up of Rapid Response Team (RRT) and training of these teams both at country and regional level. All members of the RRT were trained in all areas of readiness which included community engagement, laboratory, logistics, surveillance, case management, sample collection, packaging and shipment as well as Infection Prevention and Control (IPC).Conclusion: These trainings have led to readiness to an eventual EVD event. Countries now have the ability to respond quickly with better Emergency Operation Centre (EOC) for EVD

Association between multivitamin supplementation and mortality among patients with Ebola virus disease: an international multisite cohort study

Introduction: Micronutrient supplementation is recommended in Ebola Virus Disease (EVD) care; however, there is limited data on its therapeutic effects. Methods: This retrospective cohort study included patients with EVD admitted to five Ebola Treatment Units (ETU) in Sierra Leone and Liberia during September 2014 to December 2015. A uniform protocol was used to guide ETU care, however, due to supply limitations, only a subset of patients received multivitamins. Data on demographics, clinical characteristics, and laboratory testing was collected. The outcome of interest was facility based mortality and the primary predictor was multivitamin supplementation initiated within 48 h of admission. The multivitamin formulations included: thiamine, riboflavin, niacin and vitamins A, C, and D3. Propensity score models (PSM) were used to match patients based on covariates associated with multivitamin administration and mortality. Mortality between cases treated and untreated within 48 h of admission were compared using generalized estimating equations to calculate relative risk with bootstrap methods employed to assess statistical significance. Results: There were 424 patients with EVD who had sufficient treatment data for analysis, of which 261 (61.6%) had daily multivitamins initiated within 48 h of admission. The mean age of the cohort was 30.5 years and 59.4% were female. In the propensity score matched analysis, mortality was 53.5% among patients receiving multivitamins and 66.2% among patients not receiving multivitamins, resulting in a relative risk for mortality of 0.81 (p=0.03) for patients receiving multivitamins. Conclusion: Early multivitamin supplementation was associated with lower overall mortality. Further research on the impact of micronutrient supplementation in EVD is warranted

¿La información sobre salud está condicionada por la nacionalidad de los enfermos? El ébola como estudio de caso / Does health news depend on patients' nationality? An Ebola case study

Resumen La salud cada vez tiene más presencia en la prensa generalista, especialmente cuando los temas que se abordan afectan a países desarrollados. Esta investigación expone las diferencias que se generan en la cobertura periodista cuando ocurre un hecho relevante como pueda ser una epidemia y que afecta tanto a países occidentales como a países africanos subdesarrollados. El trabajo que presentamos evidencia que en la epidemia de Ébola, reconocida como tal por la Organización Mundial de la Salud en el año 2014, el volumen de las noticias sobre la epidemia solo aumentó la información relativa a esta enfermedad cuando hubo occidentales afectados directamente por la misma. Así se observa en los resultados que ofrece el análisis de contenido realizado en tres diarios de diferentes nacionalidades como son el español El País, el francés Le Figaro y el mexicano Reforma durante las fechas de marzo de 2014 a enero de 2015.

Abstract It is increasingly common to see the issue of health included in the general press, particularly when the topic being discussed affects developed nations. This research project shows the differences that appear in press coverage when there is a relevant event, such as an epidemic, which affects both developed, western nations and underdeveloped African ones. This work shows that, in the case of the Ebola epidemic - which was recognised as such by the World Health Organisation in 2014 -, the press only gave the problem greater coverage when there were cases of westerners being directly affected by it. That can be observed in the results of the content analysis in three daily newspapers from different countries: El País (Spain), Le Figaro (France) and Reforma (Mexico), between March 2014 and January 2015.

Objetivo: Describir relevancia de los procederes de enfermería en la sobrevivencia de los pacientes afectados por el Ébola Métodos: Estudio descriptivo, de corte transversal en Liberia, África Occidental, en el periodo de noviembre 2014 a febrero 2015. El universo estuvo constituido por 203 pacientes a quienes se les aplicó procederes de enfermería por enfermeros que integraron la brigada médica cubana. La información se obtuvo de la observación directa y la revisión de la base de datos estadística de la misión cubana en Liberia, se procesó mediante el Sistema SPSSS versión 11,5 a través de técnicas de estadística descriptiva. Resultados: Predominó el sexo masculino (55,66 por ciento), diciembre fue el mes de mayor ingreso (36,45 por ciento), la mayoría de los pacientes fueron ingresados en la salas de sospechosos (60,09 por ciento), predominó la administración de medicamentos por vía oral, con 820 procederes (52,59 por ciento), se logró que 51,25 por ciento de los pacientes atendidos egresaran vivos, siendo el mes de enero el de mayor letalidad (66,70 por ciento). Conclusiones: La labor realizada por los enfermeros cubanos en la lucha contra el Ébola en Liberia, África Occidental, y el cumplimiento estricto de los protocolos según procederes de enfermería contribuyó al control hemodinámico de los pacientes atendidos y a la disminución paulatina de la epidemia, así como la letalidad por dicho evento(AU)

Introduction: Ebola virus causes a highly infectious and serious disease, which quickly leads to death, with a death rate of up to 90 percent, but it can be prevented. Objective: To describe the relevance of nursing procedures in the survival of patients affected by Ebola. Methods: Descriptive, cross-sectional study carried out in West Africa, Liberia in the period from November 2014 to February 2015. The study population consisted of 203 patients who were applied nursing procedures by personnel who were part of the Cuban medical brigade. The information was obtained by direct observation and review of the statistical database of the Cuban mission in Liberia; and processed through the system SPSSS version 11.5, through descriptive statistics techniques. Results: The male sex predominated (55.66 percent). December was the month with highest admittance (36.45 percent); the majority of patients were admitted to the ward of suspects (60.09 percent). The administration of oral medications predominated, with 820 procedures (52.59 percent). It was achieved for 51.25 percent of the patients attended to be discharged alive, the month of January accounting for the highest mortality (66.70 percent). Conclusions: The work carried out by the Cuban nurses in the fight against Ebola in West Africa, Liberia and the strict compliance with the protocols according to nursing procedures contributed to the hemodynamic control of the patients attended and the gradual reduction of the epidemic, as well as the mortality for the event(AU)

Caracterización clínico epidemiológica de pacientes con ébola en un centro de tratamiento de Sierra Leona / Clinical-epidemiological characterization of Ebola disease in patients at a treatment center in Sierra Leone

Introducción: La enfermedad del ébola se dio a conocer por primera vez en 1976, con una letalidad muy elevada en todos los brotes detectados. Objetivo: Caracterizar clínica y epidemiológicamente a los pacientes portadores de la enfermedad por el virus del Ébola. Métodos: Se realizó un estudio observacional, descriptivo y transversal en 424 pacientes ingresados en un centro de tratamiento de ébola en la República de Sierra Leona, África occidental, con el diagnóstico confirmado mediante la técnica de reacción en cadena de la polimerasa para virus Ébola, durante el período de noviembre de 2014 hasta marzo de 2015. Resultados: Se muestra que el grupo etario más afectado fue el de 25 a 34 con un 25,9 por ciento. La mayor letalidad se presentó en los pacientes con más de 65 años de edad con un 44,4 por ciento. El síntoma que prevaleció fue la fiebre para un 61,8 por ciento, y el hipo se presentó en el 88,8 por ciento de los fallecidos. Conclusión: Se concluye que la enfermedad no tuvo distinción significativa con el sexo. La mayor letalidad se presentó en las edades geriátricas. Los síntomas más frecuentes fueron la fiebre, diarrea y el decaimiento. El hipo fue el signo que más se presentó en los pacientes que fallecieron(AU)

Introduction: Ebola disease was first reported in 1976 with a very high lethality in all outbreaks. Objective: To clinically and epidemiologically characterize the patients carriers of Ebola virus disease. Methods: we conducted an observational, descriptive and cross-sectional study in 424 patients admitted to an Ebola Treatment Center in the Republic of Sierra Leone, West Africa from November 2014 to March 2015. The polymerase chain reaction technique for Ebola virus confirmed the diagnosis. Medical records provided all data. Results: The age group most affected was 25 to 34 (25.9 percent). The highest lethality occurred in those over 65 years of age (44.4 percent ). Fever was the prevailing symptom (61.8 percent) and hiccups occurred in 88.8 percent of the deceased. Conclusion: Clinical manifestations were variable, although fever was the main symptom. Hiccup was a sign of poor prognosis when associated with a higher percentage of mortality. Lethality was high(AU)

A comprehensive district-level laboratory intervention after the ebola epidemic in Sierra Leone

Background: The 2014­2016 Ebola outbreak exposed the poor laboratory systems in Sierra Leone. Immense needs were recognised across all areas, from facilities, diagnostic capacity, supplies, trained personnel to quality assurance mechanisms.Objective: We aimed to describe the first year of a comprehensive intervention, which started in 2015, in a public hospital's general laboratory serving a population of over 500 000 in a rural district.Methods: The intervention focused on (1)supporting local authorities and healthcare workers in policy implementation and developing procedures to enhance access to services, (2) addressing gaps by investing in infrastructure, supplies, and equipment, (3) development of quality assurance mechanisms via mentorship, bench-side training, and the introduction of quality control and information systems. All work was performed alongside counterparts from the Ministry of Health and Sanitation.Results: We observed a strong increase in patient visits and inpatient and outpatient testing volumes. Novel techniques and procedures were taken up well by staff, leading to improved and expanded service and safety, laying foundations for further improvements.Conclusion: This comprehensive approach was successful and the results suggest an increase in trust from patients and healthcare workers
