The cost of public health interventions to respond to the 10th Ebola outbreak in the Democratic Republic of the Congo.

The 10th Ebola virus disease (EVD) outbreak in the Democratic Republic of the Congo (DRC) drew substantial attention from the international community, which in turn invested more than US$1 billion in EVD control over two years (2018-2020). This is the first EVD outbreak to take place in a conflict area, which led to a shift in strategy from a pure public health response (PHR) to a multisectoral humanitarian response. A wide range of disease control and mitigation activities were implemented and were outlined in the five budgeted Strategic Response Plans used throughout the 26 months. This study used the budget/expenditure and output indicators for disease control and mitigation interventions compiled by the government of DRC and development and humanitarian partners to estimate unit costs of key Ebola control interventions. Of all the investment in EVD control, 68% was spent on PHR. The remaining 32% covered security, community support interventions for the PHR. The disbursement for the public health pillar was distributed as follows: (1) coordination (18.8%), (2), clinical management of EVD cases (18.4%), (3) surveillance and vaccination (15.9%), (4) infection prevention and control/WASH (13.8%) and (5) risk communication (13.7%). The unit costs of key EVD control interventions were as follows: US$66 182 for maintaining a rapid response team per month, US$4435 for contact tracing and surveillance per identified EVD case, US$1464 for EVD treatment per case, US$59.4 per EVD laboratory test, US$120.7 per vaccinated individual against EVD and US$175.0 for mental health and psychosocial support per beneficiary. The estimated unit costs of key EVD disease control interventions provide crucial information for future infectious disease control planning and budgeting, as well as prioritisation of disease control interventions.

Impact of multimodal strategies including a pay for performance strategy in the improvement of infection prevention and control practices in healthcare facilities during an Ebola virus disease outbreak.

BACKGROUND: Strategy to mitigate various Ebola virus disease (EVD) outbreaks are focusing on Infection Prevention and Control (IPC) capacity building, supportive supervision and IPC supply donation. This study was conducted to assess the impact of a Pay for Performance Strategy (PPS) in improving IPC performance in healthcare facilities (HF) in context of the 2018-2019 Nord Kivu/ Democratic Republic of the Congo EVD outbreak. METHODS: A quasi-experimental study was conducted analysing the impact of a PPS on the IPC performance. HF were selected following the inclusion criteria upon informed consent from the facility manager and the National Department of Health. Initial and process assessment of IPC performance was conducted by integrating response teams using a validated IPC assessment tool for HF. A bundle of interventions was then implemented in the different HF including training of health workers, donation of IPC kits, supportive supervision during the implementation of IPC activities, and monetary reward. IPC practices in HF were assessment every two weeks during the intervention period to measure the impact. The IPC assessment tool had 34 questions aggregated in 8 different thematic areas: triage and isolation capacity, IPC committee in HF, hand hygiene, PPE, decontamination and sterilization, linen management, hospital environment and Waste management. Data were analysed using descriptive statistics and analytical approaches according to assumptions. R software (version 4.0.3) was used for all the analyses and a p-value of 0.05 was considered as the threshold for statistically significant results. RESULTS: Among 69 HF involved in this study, 48 were private facilities and 21 state facilities. The median baseline IPC score was 44% (IQR: 21-65%); this IPC median score reached respectively after 2, 4, 6 and 8 weeks 68% (IQR: 59-76%), 79% (71-84%), 76% (68-85%) and 79% (74-85%). The improvement of IPC score was statistically significative. Spearman's rank-order correlation revealed the associated between proportion of trained HW and IPC score performance after 8 weeks of interventions (rs = .280, p-value = 0.02). CONCLUSION: Pay for Performance Strategy was proved effective in improving healthcare facilities capacity in infection prevention and control practice in context of 2018 EVD outbreak in Nord Kivu. However, the strategy for long-term sustainability of IPC needs further provision. More studies are warranted on the HW and patients' perceptions toward IPC program implementation in context of Nord Kivu Province.

Involvement of Civil Society Organizations and Other Community Groups in the Response to the Ebola Virus Disease Outbreak in the North Kivu and Ituri Provinces of the Democratic Republic of Congo.

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. However, several challenges were encountered, namely security issues, poor awareness, and non-compliance to safety measures. The findings underscore that despite considerable experience over a long period with outbreaks in the DRC, people still need to be educated about the disease.

Community Involvement in Response to Ebola Virus Disease Epidemic in North Kivu and Ituri, Democratic Republic of Congo: A Mixed-Methods Study.

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. Community leaders, religious leaders, and Ebola survivors were interviewed using the IDI guide, while young men (≤ 30 years), young women (≤30 years), adult community males (<30 years), and adult community females (<30 years) were in separate FGD sessions. The results revealed that the urban area was the most affected by the epidemic (79.2%) compared to 20.8% in rural areas. The χ2 calculated was 18.183 (P<0.001). Community members exhibited varying degrees of involvement in response to the EVD epidemic in the two provinces. Community members were mostly engaged in information dissemination. However, they believe they could have contributed more if they had been fully engaged. These findings were derived from the qualitative data. The study contributes to evidence on how community involvement could help response to public health events globally, hence this study provides valuable insights for future public health interventions and response.

Perceptions and Rumors About the Ebola Virus Disease Vaccine in the Ituri and Kivu Provinces of the Democratic Republic of Congo.

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. The acceptance rate of the vaccine was 67.3% (below the 80% threshold needed to create herd immunity in the population). More of the urban population (31.3%) than the rural population (10.4%) accepted the vaccine. Refusals were largely due to fear that the vaccine could activate other diseases in the body and could even kill. Some feared that it was a conspiracy of the government to reduce the population in the study area through forced fertility control and death, among other such concerns. In conclusion, these rumors increased mistrust, which challenged the efforts of the government and its partners to safeguard the health of the people.

Epidemic Response amidst Insecurity: Addressing the Ebola Virus Epidemic in the Provinces of North Kivu and Ituri.

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. Since the epidemic began, teams were organized to address all aspects of the response. These response teams conducted extensive fieldwork, including epidemiological surveillance, risk communication and community involvement, infection prevention and control, vaccination, dignified and safe burials, care at transit centers and Ebola treatment centers, and medical and psychosocial care for the recovered. They faced confrontational reactions from the communities, which jeopardized their security. The insecure state of the provinces led to the destruction and damage of infrastructure, including healthcare facilities, which affected the ability of rescue teams to access people needing care as well as the resources they needed to care for the ill. Worse yet, the insecurity took other forms, including threatening and kidnapping members of the response teams, lodging protests against the response activities in towns or health zones, committing violence against teams responsible for safe and dignified burials, instigating altercations between community members and members of the response team, and encouraging general resistance by the population. This level of insecurity interrupted or even halted response activities in some areas-sometimes for more than two weeks, decreasing the efficiency of the response teams, particularly in monitoring contacts due to the inability to access certain communities. Additionally, certain acts of protest, such as community members handling bodies as a demonstration of their opposition to safe and dignified burials, likely intensified disease spread. However, the involvement of community leaders, at least, made dialogue and negotiation possible between the response teams and community members, as such efforts led to communities contributing to the security of personnel involved in the fight against the Ebola epidemic in North Kivu and Ituri provinces.

Perceptions, Disease Representations, and Response Obstacles Regarding the Ebola Virus Disease Epidemic in the North Kivu and Ituri Provinces of the Democratic Republic of the Congo.

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). The results revealed the existence of several health conditions among members of the two communities. Locals consider nearly 80 of these ailments as untreatable by orthodox medicines and methods, even when symptoms are similar to EVD. Creating awareness must be considered a critical goal of community education to further educate these populations about EVD and other health problems and their respective treatments.

Survivors and the Response to the Ebola Virus Disease in the Provinces of North Kivu and Ituri in the Democratic Republic of Congo.

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. The results revealed that the survivors suffered stigmatization and, upon return to the communities, were avoided by the community members due to fear of contamination. Some thought that the survivors should be supported in adjusting to the community, while some recommended engaging the survivors in EVD response activities.

Therapeutic Itineraries during the Ebola Epidemic in the Democratic Republic of Congo.

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. The results showed that modern healthcare facilities are not usually considered the first option for treatment. The therapeutic journey generally begins with the patients, who treat themselves based on the what they know about the disease and the resources they have at their disposal. However, if the disease is not cured through self-medication, then patients or their relatives will visit a pharmacy. Patients request medication they know to be effective in treating the disease, and relatives can also assist in obtaining medication in the case of immobile patients. Pharmacies commonly sell the medication to patients or their relatives without a medical prescription.

Response of Healthcare Service Providers, to the Ebola Virus Disease Epidemic in the Democratic Republic of Congo's North Kivu and Ituri Provinces.

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. The responses showed that the staff did not desert the health centers and remained at their jobs. Throughout this research, only one case of abandonment of duty by a nurse was reported. The healthcare system thus played a major role in responding to the COVID-19 pandemic. However, the healthcare service providers faced several challenges. Suggestions are made to enhance the contributions of healthcare service and its providers to health emergencies in the future.

Soil microbial functioning and organic carbon storage: can complex timber tree stands mimic natural forests?

Conversion of natural forest to anthropogenic land use systems (LUS) often leads to considerable loss of carbon, however, proper management of these LUS may reverse the trend. A study was conducted in a semi-deciduous forest zone of Côte d'Ivoire to assess soil microbial functioning and soil organic carbon (SOC) stocks in varying tree stands, and to determine whether complex tree stands can mimic the natural forest in terms of these soil attributes. Tree plantations studied were monocultures of teak (Tectona grandis) and full-sun cocoa (Theobroma cacao L.), and a mixture of four tree species (MTS) with Tectona grandis, Gmelina arborea, Terminalia ivoriensis and Terminalia superba. An adjacent natural forest was considered as the reference. Each of these LUS had five replicate stands where soil (0-10 cm depth) samples were taken for physico-chemical parameters and microbial biomass-C (MBC), microbial activities, MBC/SOC ratio and metabolic quotient (qCO2). SOC and total N stocks were also calculated. The C mineralization rate (mg C-CO2 kg-1) and mineral N concentration (mg kg-1) drastically declined in the monocultures of cocoa (154.9 ± 29.3 and 49.8 ± 9.8, respectively) and teak (179.6 ± 27.1 and 54.1 ± 7.3) compared to the natural forest (258.4 ± 21.9 and 108.7 ± 12). However, values in MTS (194.7 ± 24.6 and 105.4 ± 7.4) were not significantly different from those in the natural forest. Similarly, SOC stocks in MTS (28.8 ± 1.9 Mg ha-1) were not significantly different from those recorded in the natural forest (32.9 ± 1.7 Mg ha-1) whereas teak (25.4 ± 1.7 Mg ha-1) and cocoa (23.1 ± 3.4 Mg ha-1) exhibited significantly lower values. Despite the acidic soil and recalcitrant litter conditions, increased MBC/SOC ratio and decreased qCO2 were recorded in the monocrops, suggesting a probable increase in the fungi/bacteria ratio. The complex MTS stand was found to mimic the natural forest in terms of soil microbial activity and organic status, due to the provision of a diversity of litter quality, which may serve as a basis for developing a climate smart timber system in West and Central Africa.

Recommendations for the COVID-19 Response at the National Level Based on Lessons Learned from the Ebola Virus Disease Outbreak in the Democratic Republic of the Congo.

The tenth outbreak of Ebola virus disease (EVD) in North Kivu, the Democratic Republic of the Congo (DRC), was declared 8 days after the end of the ninth EVD outbreak, in the Equateur Province on August 1, 2018. With a total of 3,461 confirmed and probable cases, the North Kivu outbreak was the second largest outbreak after that in West Africa in 2014-2016, and the largest observed in the DRC. This outbreak was difficult to control because of multiple challenges, including armed conflict, population displacement, movement of contacts, community mistrust, and high population density. It took more than 21 months to control the outbreak, with critical innovations and systems put into place. We describe systems that were put into place during the EVD response in the DRC that can be leveraged for the response to the current COVID-19 global pandemic.

The potential effects of widespread community transmission of SARS-CoV-2 infection in the World Health Organization African Region: a predictive model.

The spread of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has been unprecedented in its speed and effects. Interruption of its transmission to prevent widespread community transmission is critical because its effects go beyond the number of COVID-19 cases and deaths and affect the health system capacity to provide other essential services. Highlighting the implications of such a situation, the predictions presented here are derived using a Markov chain model, with the transition states and country specific probabilities derived based on currently available knowledge. A risk of exposure, and vulnerability index are used to make the probabilities country specific. The results predict a high risk of exposure in states of small size, together with Algeria, South Africa and Cameroon. Nigeria will have the largest number of infections, followed by Algeria and South Africa. Mauritania would have the fewest cases, followed by Seychelles and Eritrea. Per capita, Mauritius, Seychelles and Equatorial Guinea would have the highest proportion of their population affected, while Niger, Mauritania and Chad would have the lowest. Of the World Health Organization's 1 billion population in Africa, 22% (16%-26%) will be infected in the first year, with 37 (29 - 44) million symptomatic cases and 150 078 (82 735-189 579) deaths. There will be an estimated 4.6 (3.6-5.5) million COVID-19 hospitalisations, of which 139 521 (81 876-167 044) would be severe cases requiring oxygen, and 89 043 (52 253-106 599) critical cases requiring breathing support. The needed mitigation measures would significantly strain health system capacities, particularly for secondary and tertiary services, while many cases may pass undetected in primary care facilities due to weak diagnostic capacity and non-specific symptoms. The effect of avoiding widespread and sustained community transmission of SARS-CoV-2 is significant, and most likely outweighs any costs of preventing such a scenario. Effective containment measures should be promoted in all countries to best manage the COVID-19 pandemic.

What are the drivers of recurrent cholera transmission in Nigeria? Evidence from a scoping review.

BACKGROUND: The 2018 cholera outbreak in Nigeria affected over half of the states in the country, and was characterised by high attack and case fatality rates. The country continues to record cholera cases and related deaths to date. However, there is a dearth of evidence on context-specific drivers and their operational mechanisms in mediating recurrent cholera transmission in Nigeria. This study therefore aimed to fill this important research gap, with a view to informing the design and implementation of appropriate preventive and control measures. METHODS: Four bibliographic literature sources (CINAHL (Plus with full text), Web of Science, Google Scholar and PubMed), and one journal (African Journals Online) were searched to retrieve documents relating to cholera transmission in Nigeria. Titles and abstracts of the identified documents were screened according to a predefined study protocol. Data extraction and bibliometric analysis of all eligible documents were conducted, which was followed by thematic and systematic analyses. RESULTS: Forty-five documents met the inclusion criteria and were included in the final analysis. The majority of the documents were peer-reviewed journal articles (89%) and conducted predominantly in the context of cholera epidemics (64%). The narrative analysis indicates that social, biological, environmental and climatic, health systems, and a combination of two or more factors appear to drive cholera transmission in Nigeria. Regarding operational dynamics, a substantial number of the identified drivers appear to be functionally interdependent of each other. CONCLUSION: The drivers of recurring cholera transmission in Nigeria are diverse but functionally interdependent; thus, underlining the importance of adopting a multi-sectoral approach for cholera prevention and control.

The cost of insecurity: from flare-up to control of a major Ebola virus disease hotspot during the outbreak in the Democratic Republic of the Congo, 2019.

The ongoing Ebola outbreak in the eastern Democratic Republic of the Congo is facing unprecedented levels of insecurity and violence. We evaluate the likely impact in terms of added transmissibility and cases of major security incidents in the Butembo coordination hub. We also show that despite this additional burden, an adapted response strategy involving enlarged ring vaccination around clusters of cases and enhanced community engagement managed to bring this main hotspot under control.

Identifying and quantifying the factors associated with cholera-related death during the 2018 outbreak in Nigeria.

INTRODUCTION: cholera outbreaks in Nigeria are often associated with high case fatality rates; however, there is a dearth of evidence on context-specific factors associated with the trend. This study therefore aimed to identify and quantify the factors associated with cholera-related deaths in Nigeria. METHODS: using a cross-sectional design, we analysed surveillance data from all the States that reported cholera cases during the 2018 outbreak, and defined cholera-related death as death of an individual classified as having cholera according to the Nigeria Centre for Disease Control case definition. Factors associated with cholera-related death were assessed using multivariable logistic regression and findings presented as adjusted odds ratios (ORs) with 95% Confidence Intervals (95% CIs). RESULTS: between January 1 and November 19, 2018, 41,394 cholera cases were reported across 20 States, including 815 cholera-related deaths. In the adjusted multivariable model, older age, male gender, living in peri-urban areas or in flooded states, infection during the rainy season, and delay in seeking health care by >2 days were positively associated with cholera-related death; whereas living in urban areas, hospitalisation in the course of illness, and presentation to a secondary hospital were negatively associated with cholera-related death. CONCLUSION: cholera-related deaths during the 2018 outbreak in Nigeria appeared to be driven by multiple factors, which further reemphasises the importance of adopting a multisectoral approach to the design and implementation of context-specific interventions in Nigeria.

The COVID-19 pandemic: research and health development in the World Health Organisation Africa region.

Concerns have been expressed about the view point of WHO AFRO concerning research for health in the African Region. WHO AFRO considers research a critical component in the improvement of health in the Africa region. Ensuring the effectiveness of our strategies, policies and programmes requires evidence. In the context of the ongoing COVID-19 outbreak, WHO research interests cover key areas of the response. The WHO AFRO consider research as critical in our efforts at protecting people against health emergencies and pandemics like the COVID-19 and ensuring universal access to proven interventions. In view of this, the WHO has taken steps to strengthen capacity for research in the region. The results of these efforts may take time to manifest but will surely do as we persist in our drive, with support from our partners.

A Public Health Response to a Mudslide in Freetown, Sierra Leone, 2017: Lessons Learnt.

On August 14, 2017, a 6-kilometer mudslide occurred in Regent Area, Western Area District of Sierra Leone following a torrential downpour that lasted 3 days. More than 300 houses along River Juba were submerged; 1141 people were reported dead or missing and 5905 displaced. In response to the mudslide, the World Health Organization (WHO) Country Office in Sierra Leone moved swiftly to verify the emergency and constitute an incident management team to coordinate the response. Early contact was made with the Ministry of Health and Sanitation and health sector partners. A Public Health Emergency Operations Center was set up to coordinate the response. Joint assessments, planning, and response among health sector partners ensured effectiveness and efficiency. Oral cholera vaccination was administered to high-risk populations to prevent a cholera outbreak. Surveillance for 4 waterborne diseases was enhanced through daily reporting from 9 health facilities serving the affected population. Performance standards from the WHO Emergency Response Framework were used to monitor the emergency response. An assessment of the country's performance showed that the country's response was well executed. To improve future response, we recommend enhanced district level preparedness, update of disaster response protocols, and pre-disaster mapping of health sector partners.

Descriptive epidemiology of cholera outbreak in Nigeria, January-November, 2018: implications for the global roadmap strategy.

BACKGROUND: The cholera outbreak in 2018 in Nigeria reaffirms its public health threat to the country. Evidence on the current epidemiology of cholera required for the design and implementation of appropriate interventions towards attaining the global roadmap strategic goals for cholera elimination however seems lacking. Thus, this study aimed at addressing this gap by describing the epidemiology of the 2018 cholera outbreak in Nigeria. METHODS: This was a retrospective analysis of surveillance data collected between January 1st and November 19th, 2018. A cholera case was defined as an individual aged 2 years or older presenting with acute watery diarrhoea and severe dehydration or dying from acute watery diarrhoea. Descriptive analyses were performed and presented with respect to person, time and place using appropriate statistics. RESULTS: There were 43,996 cholera cases and 836 cholera deaths across 20 states in Nigeria during the outbreak period, with an attack rate (AR) of 127.43/100,000 population and a case fatality rate (CFR) of 1.90%. Individuals aged 15 years or older (47.76%) were the most affected age group, but the proportion of affected males and females was about the same (49.00 and 51.00% respectively). The outbreak was characterised by four distinct epidemic waves, with higher number of deaths recorded in the third and fourth waves. States from the north-west and north-east regions of the country recorded the highest ARs while those from the north-central recorded the highest CFRs. CONCLUSION: The severity and wide-geographical distribution of cholera cases and deaths during the 2018 outbreak are indicative of an elevated burden, which was more notable in the northern region of the country. Overall, the findings reaffirm the strategic role of a multi-sectoral approach in the design and implementation of public health interventions aimed at preventing and controlling cholera in Nigeria.
