BACKGROUND: Despite frequently providing non-military services in times of crisis, little systematic research has examined the perspectives of crisis-affected community members on the role of armed actors responding to humanitarian crises and public health emergencies. METHODS: To address this research gap, 175 interviews were conducted (2020-2021) amongst humanitarian and public health practitioners; armed actors; and crisis-affected community members across three country and four crisis contexts...

BACKGROUND: Health-care providers and front-line workers are at risk of contracting Ebola virus disease during an Ebola virus outbreak and consequently of becoming drivers of the disease. We aimed to assess the long-term immunogenicity of the Ad26.ZEBOV, MVA-BN-Filo vaccine regimen and the safety of and immune memory response to an Ad26.ZEBOV booster vaccination at 1 year or 2 years after the first dose in this at-risk population. METHODS: This open-label, single-centre, randomised, phase 2 trial was conducted at one study site within a hospital in Boende, Democratic Republic of the Congo...

BACKGROUND: Reducing Ebola virus transmission relies on the ability to identify cases and limit contact with infected bodily fluids through biosecurity, safe sex practices, safe burial and vaccination. Armed conflicts can complicate outbreak detection and interventions due to widespread disruption to governments and populations. Guinea and the Democratic Republic of the Congo (DRC) have historically reported the largest and the most recent Ebola virus outbreaks. Understanding if conflict played a role in these outbreaks may help in identifying key risks factors to improve disease control...

Ebola virus (EBOV) infection is threatening human health, especially in Central and West Africa. Limited clinical trials and the requirement of biosafety level-4 laboratories hinder experimental work to advance our understanding of EBOV and the evaluation of treatment. In this work, we use a computational model to study the assembly and budding process of EBOV and evaluate the effect of fendiline on these processes in the context of fluctuating host membrane lipid levels. Our results demonstrate for the first time that the assembly of VP40 filaments may follow the nucleation-elongation theory, as this mechanism is critical to maintaining a pool of VP40 dimers for the maturation and production of virus-like particles (VLPs)...

BACKGROUND: Although multiple prognostic models exist for Ebola virus disease mortality, few incorporate biomarkers, and none has used longitudinal point-of-care serum testing throughout Ebola treatment center care. METHODS: This retrospective study evaluated adult patients with Ebola virus disease during the 10th outbreak in the Democratic Republic of Congo. Ebola virus cycle threshold (Ct; based on reverse transcriptase polymerase chain reaction) and point-of-care serum biomarker values were collected throughout Ebola treatment center care...

We reviewed the involvement of civil society organizations as well as other community level organizations and structures in the response to the Ebola Virus Disease (EVD) outbreak in the Democratic Republic of Congo. A total of 800 randomly selected adults were surveyed using a uniform set of structured questionnaires. An in-depth interview guide was employed to collect information from community members and religious leaders, while focus group discussions were held with community members. The results revealed some involvement of the different organizations in the communities in the response to the EVD outbreak...

BACKGROUND: The rVSVΔG-ZEBOV-GP vaccine constitutes a valuable tool to control Ebola virus disease outbreaks. This retrospective cohort study aimed to assess the protective effect of the vaccine against death among patients with confirmed Ebola virus disease. METHODS: In this retrospective cohort analysis of patients with confirmed Ebola virus disease admitted to Ebola health facilities in the Democratic Republic of the Congo between July 27, 2018, and April 27, 2020, we performed univariate and multivariate analyses to assess case fatality risk and cycle threshold for nucleoprotein according to vaccination status, Ebola virus disease-specific treatments (eg, mAb114 and REGN-EB3), and other risk factors...

Healthcare service providers are crucial for effective responses to disease outbreaks. However, their performance is dependent on the level of system inputs, people's perception of the system, and their willingness to use health services. This study investigated the functionality of health services and healthcare providers in the Democratic Republic of Congo during the tenth Ebola virus disease outbreak. It employed qualitative methods, including 24 in-depth interviews of healthcare providers and community leaders, and 12 focus-group discussions with community members...

While treating a disease, patients or their relatives make decisions to pursue different therapeutic options, and various stages are involved in searching for a cure. This paper explored the pattern of health-seeking in the Democratic Republic of Congo (DRC) during the 10th Ebola virus disease (EVD) outbreak. Eight hundred randomly selected adults were surveyed using a questionnaire. Qualitative data were also collected through in-depth interviews with 17 community leaders and 20 focus group discussions with community members...

We explored issues around the integration of survivors in communities and the implications for the Ebola Virus Disease (EVD) response in the Democratic Republic of Congo (DRC). We conducted a survey with 800 randomly selected respondents using a structured questionnaire. Respondents were persons aged 18 years and above. Focus group discussions (FGDs) and in-depth interviews (IDIs) were employed to obtain contextual data on the issues. Community leaders, health workers, and response pillar leads engaged in IDIs, while community members were involved in FGDs...

Treatment centers (TCs) are the only locations designed to care for people with Ebola virus disease (EVD) symptoms. These people and their families are held at a TC as soon as they arrive at an Ebola treatment center (ETC); however, some people escape from TCs. This paper explored alternative care platforms for symptomatic people in the fight against the EVD outbreak in the Democratic Republic of Congo. Eight hundred randomly selected adults aged 18 years and above were surveyed with a uniform set of structured questionnaires...

We explored the perceptions and representations of diseases in the North Kivu and Ituri provinces of the Democratic Republic of Congo to identify perceived obstacles regarding responses to the country 's Ebola virus disease (EVD) outbreak using a mix-methods approach. We surveyed a representative sample including 800 adults aged 18 years and older, held in-depth interviews with 17 community leaders, and conducted 10 focus group discussions with community members (using same-sex interviewers/discussion leaders)...

Perceptions and rumors about vaccinations can contribute to vaccine hesitancy. This study aimed to examine perceptions and rumors about the Ebola vaccine during the 10th Ebola Virus Disease outbreak in the Ituri and North Kivu provinces of the Democratic Republic of Congo. Eight hundred randomly selected respondents were surveyed with a uniform structured questionnaire. Further, we collected qualitative data through focus group discussions and using in-depth interview guides. Results revealed several misperceptions and rumors about the vaccine, which led to some level of vaccine hesitancy and refusal among the people...

Traditional healers co-exist with orthodox medicine, especially in cases with perceived supernatural causes and during outbreaks of infectious diseases like the Ebola virus disease (EVD) in the North Kivu and Ituri provinces in the Democratic Republic of the Congo (DRC). In this study, we examined the role and potential of involving traditional healers in the national response to the Ebola virus disease outbreak in the DRC. Seventeen community leaders and 20 traditional healers were interviewed. The traditional healers managed symptoms with herbs and were not inclined to refer cases to orthodox healthcare facilities because of their confidence in their ability to handle cases with supernatural causes...

Although an outbreak of the Ebola virus disease affects an entire population, women are more susceptible to the virus than men. Throughout the outbreaks of the Ebola virus disease in Central and West Africa, women have been impacted more significantly. Generally, over half of those who become ill are women. The situation is the same in terms of mortality. Further, the outcomes of the epidemic negatively affect women socially, as many become the heads of households following the loss of their spouses, which burdens them with new responsibilities...

We investigated the involvement of community members in response to the Ebola Virus Disease (EVD) epidemic in the North Kivu and Ituri provinces of the Democratic Republic of Congo. This cross-sectional study, conducted using mixed methods of data collection, included a uniformly structured questionnaire survey, which was administered to 800 randomly selected adults (aged ≥ 18 years). Further, we used qualitative tools of inquiry-focus group discussions (FGD) and in-depth interviews (IDI)-to guide the context of the information collected in the survey...

Denial and rumors are two major obstacles impairing the implementation of activities in response to the Ebola virus disease (EVD) epidemic. This study investigated the roles of denial and rumors, among other challenges, in complicating the response to the EVD outbreak in the North Kivu and Ituri provinces of the Democratic Republic of the Congo. A total of 800 randomly selected respondents were surveyed using a structured questionnaire. In-depth interviews were conducted with 17 community religious and opinion leaders, as well as Ebola survivors...

This paper examines the impact of insecurity on the management of the Ebola virus disease epidemic in the Democratic Republic of the Congo provinces of North Kivu and Ituri. In these provinces, insecurity has been one of the biggest obstacles in the response to the Ebola outbreak. When the epidemic began, these provinces were already insecure-creating unfavorable circumstances for implementing epidemic response activities. While the ninth epidemic in the Equateur province was brought under control in record time, the same was not true for the tenth epidemic in North Kivu and Ituri...

BACKGROUND: Ebola virus (EBOV) is a genus of negative-strand RNA viruses belonging to the family Filoviradae that was first described in 1976 in the present-day Democratic Republic of the Congo. It has intermittently affected substantial human populations in West Africa and presents itself as a global health menace due to the high mortality rate of patients, high transmission rate, difficult patient management, and the emergence of complicated autoimmune disease-like conditions post-infection...

As the high pathogenic species of Filoviridae virus family, Orthoebolavirus zairense (EBOV) shows frequent outbreaks in human in recently years since its first emerging in 1976 in Democratic Republic of the Congo (COD), bringing ongoing risks and burden on public health safety. Here, the phylogenetic relationship among major outbreaks was analyzed. The results showed that EBOV isolates could be divided into four lineages according to spatial and temporal epidemics. Then, the positive selection sites (PSS) were detected on all proteins of the EBOV, exhibiting lineage characteristic...
