Ongoing Ebola virus disease outbreaks in the Democratic Republic of the Congo follow the largest recorded outbreak in Western Africa (2013–2016). To combat outbreaks, testing of medical countermeasures (therapeutics or vaccines) requires a well-defined, reproducible, animal model. Here we present Ebola virus disease kinetics in 24 Chinese-origin rhesus monkeys exposed intramuscularly to a highly characterized, commercially available Kikwit Ebola virus Filovirus Animal Non-Clinical Group (FANG) stock. Until reaching predetermined clinical disease endpoint criteria, six animals underwent anesthesia for repeated clinical sampling and were compared to six that did not. Groups of three animals were euthanized and necropsied on days 3, 4, 5, and 6 post-exposure, respectively. In addition, three uninfected animals served as controls. Here, we present detailed characterization of clinical and laboratory disease kinetics and complete blood counts, serum chemistries, Ebola virus titers, and disease kinetics for future medical countermeasure (MCM) study design and control data. We measured no statistical difference in hematology, chemistry values, or time to clinical endpoint in animals that were anesthetized for clinical sampling during the acute disease compared to those that were not.

Abstract Background Ebola Virus Disease (EVD) is a deadly and feared infectious disease, which can be responsible of debilitating physical and psychological sequelae in survivors including depression and anxiety disorders. Unfortunately, there are scarce data on survivor sequelae in Democratic Republic of the Congo. So this study assessed PTSD, depression and anxiety symptoms among EVD survivors enrolled in the follow-up program of the psychosocial care team of Beni town’s general hospital. Methods A cross-sectional study used consecutive sampling to recruit 144 Ebola virus disease survivors who came for follow up from October 23 to November 13; 2019. Basic socio-demographic data, presence of headache and short-term memory function were assessed. The Post-traumatic Checklist Scale and Hospital Anxiety and Depression Scale were used to assess psychological burden among participants. Descriptive statistics were used to summarized data and Pearson’s or likelihood chi-square were used to test association between psychiatric disorders and associated factors. Results The prevalence of PTSD, depression and anxiety was 24.3, 24.3 and 33.3% respectively. Being male (OR = 0.42, 95% CI: 0.16, 0.95, p = 0.049), suffering from persistent headache (OR = 2.62, 95% CI: 1.12, 6.14, p = 0.014), losing a loved one because of EVD (OR: 2.60, 95% CI: 1.11, 6.15, p = 0. 015) and being young − 18-24 years - (OR: 0. 261, 95% CI: 0. 08, 0.82, p = 0,026) were statistically associated with PTSD diagnosis. Having short-term memory impairment and suffering from persistent headache were statistically associated with depression and anxiety diagnoses (OR = 2.44, 95% CI: 1.03, 5.82, p = 0.026); (OR = 2.24, 95% CI: 1.04, 4.85, p = 0.025); (OR = 2.62, 95% CI: 1.12, 6.14, p = 0.014); (OR = 2.31, 95% CI: 1.06, 5.01, p = 0.020). Conclusion The prevalence of PTSD, depression and anxiety is high among EVD survivors. Development of specialized psychiatric services to sustain psychiatric and psychological health amongst survivors in the cultural context of the Eastern part of the DRC should be considered by the teams fighting against EVD in the DRC.

AbstractIntroduction:Ebola Virus Disease (EVD) is the international health emergency paradigm due to its epidemiological presentation pattern, impact on public health, resources necessary for its control, and need for a national and international response.Study Objective:The objective of this work is to study the evolution and progression of the epidemiological presentation profile of Ebola disease outbreaks since its discovery in 1976 to the present, and to explore the possible reasons for this evolution from different perspectives.Methods:Retrospective observational study of 38 outbreaks of Ebola disease occurred from 1976 through 2019, excluding laboratory accidents. United Nations agencies and programs; Ministries of Health; the US Centers for Disease Control and Prevention (CDC); ReliefWeb; emergency nongovernmental organizations; and publications indexed in PubMed, EmBase, and Clinical Key have been used as sources of data. Information on the year of the outbreak, date of beginning and end, duration of the outbreak in days, number of cases, number of deaths, population at risk, geographic extension affected in Km2, and time of notification of the first cases to the World Health Organization (WHO) have been searched and analyzed.Results:Populations at risk have increased (P = .024) and the geographical extent of Ebola outbreaks has grown (P = .004). Reporting time of the first cases of Ebola to WHO has been reduced (P = .017) and case fatality (P = .028) has gone from 88% to 62% in the period studied. There have been differences (P = .04) between the outbreaks produced by the Sudan and Zaire strains of the virus, both in terms of duration and case fatality ratio (Sudan strain 74.5 days on average and 62.7% of case fatality ratio versus Zaire strain with 150 days on average and 55.4% case fatality ratio).Conclusion:There has been a change in the epidemiological profile of the Ebola outbreaks from 1976 through 2019 with an increase in the geographical extent of the outbreaks and the population at risk, as well as a significant decrease in the outbreaks case fatality rate. There have been advances in the detection and management capacity of outbreaks, and the notification time to the WHO has been reduced. However, there are social, economic, cultural, and political obstacles that continue to greatly hinder a more efficient epidemiological approach to Ebola disease, mainly in Central Africa.

Clear And Present Danger

An epidemic of Ebola virus disease is occurring in Western Africa on a scale not seen before, particularly in the countries of Guinea, Liberia, and Sierra Leone. The continued spread is facilitated by insufficient medical facilities, poor sanitation, travel, and unsafe burial practices. Several patients diagnosed with Ebola virus disease in Africa have been evacuated to the United States for treatment, and several other patients have been diagnosed in the United States. It is important for laboratories to be aware of available tests, especially those granted emergency use authorization, as hospitals prepare protocols for the diagnosis and management of high-risk patients.

Descriptive statistics and a binary logistic regression model were used for analysis. Results The prevalence of PTSD, depression and anxiety was 24.3%, 24.3% and 33.3% respectively. Being male (p = 0.049 ; OR = 0. 42 (CI : 0. 16–0.95), suffering from persistent headache (p = 0. 014 OR = 2.62 CI (1.12–6.14), losing a loved one because of EVD (p = 0. 015 ; OR : 2.60 (CI : 1.11–6.15) and being young − 18–24 years - (p = 0,026 ; OR : 0. 261 (IC : 0. 018-0.055).) were statistically associated with PTSD diagnosis. Having short-term memory impairment and suffering from persistent headache were statistically associated with depression and anxiety diagnoses (p = 0.026 OR = 2,44 (CI : 1.03–5.82) ; (p = 0. 025 OR = 2.24 (CI : 1.04–4.85) ; (p = 0.014 OR = 2.62 (CI : 1.12–6.14) ; (p = 0. 020 OR = 2.31 (CI : 1.06–5.01) Conclusion The prevalence of PTSD, depression and anxiety is high among EVD survivors.

Past Experiences

Over the years, the African continent has had to battle several outbreaks of infectious diseases in different countries. Some of the most deadly were the Ebola virus disease (EVD) outbreaks that occurred in West Africa between 2014 and 2016 affecting Guinea, Liberia, and Sierra Leone and, more recently, from 2018 to 2020 in the Democratic Republic of Congo (DRC). In the era of the COVID-19 pandemic, it is important that as a continent, we draw lessons and insights from our past experiences to guide outbreak response strategies being deployed to curb the latest onslaught. The Ebola outbreaks have shown that disease outbreaks should not be seen only as medical emergencies, but as full blown humanitarian crises, because oftentimes, their socio-economic impacts are more devastating than the more obvious cost to life. In this mini-review, we explore the possible humanitarian costs of the COVID-19 pandemic on the African continent by looking through the lens of our past experiences with the EVD outbreaks, highlighting how the current pandemic could significantly affect the African economy, food security, and vulnerable demographics, like children and the sexual and reproductive health and rights of women and girls. We then proffer recommendations that could be instrumental in preventing a double tragedy involving the devastating health consequences of the virus itself and the deadly fallout from its multi-sectoral knock-on effects in African countries.
