Assessment of prevalence and determinants of anxiety and psychological distress symptoms in Ebola child and adolescent survivors and orphans in Eastern Democratic Republic of the Congo during the COVID-19 pandemic.

BACKGROUND: To date, only three studies investigated the mental health of youth affected by Ebola virus disease (EVD). None explored anxiety and psychological distress symptoms in survivors or orphans. This study aimed to investigate the prevalence and determinants of anxiety and psychological distress symptoms among survivors and orphans of the 2018-2020 Ebola epidemic in Eastern Democratic Republic of the Congo (DRC) during the COVID-19 pandemic. METHODS: A representative sample of 416 participants (mean age = 13.37, SD = 2.79, 51.20 % girls, 146 survivors, 233 orphans, and 34 orphan-survivor participants) completed measures evaluating anxiety, psychological distress, exposure, resilience, stigmatization related to Ebola and COVID-19. RESULTS: 55.88 % and 55.96 % of survivors and orphans experienced severe symptoms of anxiety and psychological distress. Participants who were both survivors and orphans presented higher prevalence of anxiety and psychological distress (94.12 % and 100 %) compared to survivors (74.03 % and 81.82 %) or orphans (37.99 % and 33.33 %), χ2 = 70.63, p < .001; χ2 = 113.50, p < .001. Ebola and COVID-19 related stigmatization were the most important determinants of anxiety (B = 0.40, p < .001; B = 0.37, p < .001) and psychological distress (B = 0.48, p < .001; B = 0.44, p < .001). Resilience was negatively associated with both anxiety and psychological distress. The final regression models explained 49 % and 85 % of the variance of anxiety and psychological distress. LIMITATIONS: The cross-sectional design used prevents to establish causal link. CONCLUSIONS: Ebola children and adolescents' survivors and orphans are at major risk of experiencing anxiety and psychological distress in Eastern RDC affected by years of armed conflict. Massive resources are needed to develop and implement programs to reduce stigma and support mental health.

Psychological distress among healthcare professionals in Mbarara, following the 2022 Ebola Virus Disease outbreak in Uganda: a mixed methods study.

BACKGROUND: The 2022 Ebola Virus Disease (EVD) outbreak occurred at a time when Uganda was still battling the social and psychological challenges of the COVID-19 pandemic; placing health care professionals (HCPs) at a much higher risk of developing psychological distress. Psychological distress among HCPs can cause decreased workplace productivity and ineffective management of their patients. The current study aimed to investigate and understand psychological distress among HCPS in Mbarara city in Southwestern Uganda following the 2022 EVD outbreak. METHOD: We enrolled 200 HCPs through convenient sampling from one private and one public health facility in Mbarara city in Southwestern Uganda, in a cross-sectional convergent parallel mixed method approach where qualitative and quantitative data were collected concurrently. Quantitative data, utilizing the Kessler Psychological Distress (K10) Scale, provided us with a quantitative measure of the prevalence of psychological distress among HCPs, and were analyzed using STATA version 16. Qualitative data, on the other hand, offered deeper insights into the nature, perceptions, and contextual factors influencing this distress, and were analyzed using emergent theme analysis. RESULTS: The prevalence of psychological distress was 59.5% and it was higher among females (63.9%) compared to males (36.1%). HCPs vividly expressed distress and anxiety, with heightened suspicion that every patient might be an EVD carrier, creating a pervasive sense of unsafety in the workplace. However, the outbreak had an educational affect where concerns about the announcement of another EVD outbreak were diverse, with HCPs expressing anxiety, despair, and dissatisfaction with the country's management of potential outbreaks. CONCLUSION: High levels of psychological distress were experienced by HCPs in Southwestern Uganda as a result of the 2022 EVD pandemic. HCPs express a wide range of feelings, such as dread, anxiety, despair, pessimism, and discontent with the way the outbreaks are handled throughout the nation. We recommend implementation of comprehensive psychosocial support programs tailored to the unique needs of HCPs, including counseling services, stress management workshops, and peer support networks.

Resilience of mental health services amidst Ebola disease outbreaks in Africa.

Introduction: Health systems including mental health (MH) systems are resilient if they protect human life and produce better health outcomes for all during disease outbreaks or epidemics like Ebola disease and their aftermaths. We explored the resilience of MH services amidst Ebola disease outbreaks in Africa; specifically, to (i) describe the pre-, during-, and post-Ebola disease outbreak MH systems in African countries that have experienced Ebola disease outbreaks, (ii) determine the prevalence of three high burden MH disorders and how those prevalences interact with Ebola disease outbreaks, and, (iii) describe the resilience of MH systems in the context of these outbreaks. Methods: This was a scoping review employing an adapted PRISMA statement. We conducted a five-step Boolean strategy with both free text and Medical Subject Headings (MeSH) to search 9 electronic databases and also searched WHO MINDbank and MH Atlas. Results: The literature search yielded 1,230 publications. Twenty-five studies were included involving 13,449 participants. By 2023, 13 African nations had encountered a total of 35 Ebola outbreak events. None of these countries had a metric recorded in MH Atlas to assess the inclusion of MH in emergency plans. The three highest-burden outbreak-associated MH disorders under the MH and Psychosocial Support (MHPSS) framework were depression, post-traumatic stress disorder (PTSD), and anxiety with prevalence ranges of 1.4-7%, 2-90%, and 1.3-88%, respectively. Furthermore, our analysis revealed a concerning lack of resilience within the MH systems, as evidenced by the absence of pre-existing metrics to gauge MH preparedness in emergency plans. Additionally, none of the studies evaluated the resilience of MH services for individuals with pre-existing needs or examined potential post-outbreak degradation in core MH services. Discussion: Our findings revealed an insufficiency of resilience, with no evaluation of services for individuals with pre-existing needs or post-outbreak degradation in core MH services. Strengthening MH resilience guided by evidence-based frameworks must be a priority to mitigate the long-term impacts of epidemics on mental well-being.

The state of mental health among Ebola virus disease survivors through a cross-sectional study in Sierra Leone.

BACKGROUND: The West African Ebola virus disease (EVD) epidemic resulted in >28 000 disease cases and >11 000 fatalities. The unprecedented number of survivors from this epidemic has raised questions about the long-term mental health impacts of EVD survivorship and the capacity to meet these needs. OBJECTIVES: Assess the frequency and factors associated with mental health consequences of EVD survivorship in Sierra Leone. METHODS: A cross-sectional study of 595 EVD survivors and 403 close contacts (n=998) from Sierra Leone assessed via in-person survey between November 2021 and March 2022. The assessment included validated mental health screening tools (Patient Health Questionnaire-9, PTSD Checklist-5, Alcohol Use Disorders Identification Test, Drug Abuse Screening Test-20) to indicate the presence/absence of disorder. The frequency of each disorder and factors associated with each disorder were assessed. FINDINGS: EVD-associated post-traumatic stress disorder (PTSD) was reported by 45.7% (n=257) of EVD survivors. Moreover, 3.9% (n=22) and 12.0% (n=67) of EVD survivors reported major depression (MD) and substance use, respectively; all mental health outcomes were higher than baseline rates in the region (PTSD: 6%-16%, MD: 1.1%, substance use: 2.2%). PTSD among EVD survivors was associated with acute EVD duration of ≥21 days (adjusted OR, AOR 2.24, 95% CI 1.16 to 4.43), 35-44 years of age (AOR 3.31, 95% CI 1.33 to 8.24; AOR 2.99, 95% CI 1.09 to 8.24) and residential mobility (AOR 4.16, 95% CI 2.35 to 7.35). CONCLUSIONS: Concerningly, the levels of mental health disorders among EVD survivors in Sierra Leone remained elevated 6-8 years after recovery. CLINICAL IMPLICATIONS: Results can be used to inform policy efforts and target resources to address mental health in EVD survivors.

Tweeting Jokes, Tweeting Hope: Humor Practices during the 2014 Ebola Outbreak.

In this article, we examine how humor practices on Twitter resist dominant emotion norms during an emerging disease outbreak. Humor may seem frivolous or irreverent but can constitute a powerful practice for channeling and managing difficult emotions - like anxiety and fear - during an outbreak. We find that the use of AAVE (African-American Vernacular English) and Black cultural references were widespread in Ebola-related tweets using humor. Together these communicative practices constitute Black Twitter. Humor can signal membership in Black culture while also performing and managing specific emotions in relation to epidemic risk in online spaces. Humor practices on Black Twitter were more likely to reimagine social connections despite the risks posed by the epidemic, whereas mainstream forms of humor emphasized retreat and self-isolation in response to an epidemic threat. These findings center the agency and creativity of this influential digital community while showing the variability of communication practices among a group facing disproportionate vulnerability to outbreaks and public health threats. The implications for public health messaging are discussed.

Cross-sectional study of mental health and sexual behaviours for Ebola Survivors in Beni, Butembo and Katwa health zones of the Democratic Republic of Congo.

OBJECTIVES: To understand the prevalence of mental health disorders in Ebola-affected communities and their association with condom use. DESIGN: Cross-sectional study. SETTING: Beni, Butembo and Katwa health zones, Democratic Republic of Congo (DRC). PARTICIPANTS: 223 adult Ebola survivors, 102 sexual partners and 74 comparison respondents. PRIMARY AND SECONDARY OUTCOME MEASURES: Post-traumatic stress disorder (PTSD), depression, anxiety, substance use, suicidal ideation and attempts, stigma, condom use and sexual behaviour. RESULTS: Most respondents reported to be married, Christian, from the Nande ethnic group, and farmers/herders. Survivors met symptom criteria for depression at higher rates than partners (23.5% (95% CI 18.0 to 29.1) vs 5.7 (1.2 to 10.1); p<0.001). PTSD symptom criteria for survivors (24.1%, 95% CI 18.5% to 29.7%) and partners (16.7%, 95% CI 9.4% to 23.9%) were four times greater than the comparison participants (6.0%, 95% CI 0.6% to 11.4%). Two times as many survivors as partners reported that sexual activity precautions were discussed at discharge (71.5% (95% CI 65.6 to 77.5) vs 36.2% (95% CI 26.9 to 45.5); p<0.001). The majority of survivors (95.0 (95% CI 85.1% to 98.5%) and partners 98.5% (95% CI 89.6% to 99.8%; p=0.26) participated in risky sexual behaviour after the survivor left the Ebola treatment centre. The ability to refuse sex or insist on condom use before Ebola had a threefold increase in the odds of condom use (adjusted OR 3.3, 95% CI 1.7 to 6.1, p<0.001). Up to 36% of the comparison group held discriminatory views of survivors. CONCLUSIONS: The new outbreaks in both Guinea and DRC show Ebola remains in semen longer than previously known. Understanding and addressing condom non-use and updating condom use guidelines are necessary to protect against future Ebola outbreaks, especially among sexual partners who did not have similar access to health information regarding sexual transmission of Ebola. Mental health treatment and decreasing stigma in Ebola areas is a priority.

Community trust of government and non-governmental organizations during the 2014-16 Ebola epidemic in Liberia.

The West African Ebola Virus Disease epidemic of 2014-16 cost more than 11,000 lives. Interventions targeting key behaviors to curb transmission, such as safe funeral practices and reporting and isolating the ill, were initially unsuccessful in a climate of fear, mistrust, and denial. Building trust was eventually recognized as essential to epidemic response and prioritized, and trust was seen to improve toward the end of the epidemic as incidence fell. However, little is understood about how and why trust changed during Ebola, what factors were most influential to community trust, and how different institutions might have been perceived under different levels of exposure to the outbreak. In this large-N household survey conducted in Liberia in 2018, we measured self-reported trust over time retrospectively in three different communities with different exposures to Ebola. We found trust was consistently higher for non-governmental organizations than for the government of Liberia across all time periods. Trust reportedly decreased significantly from the start to the peak of the epidemic in the study site of highest Ebola incidence. This finding, in combination with a negative association found between knowing someone infected and trust of both iNGOs and the government, indicates the experience of Ebola may have itself caused a decline of trust in the community. These results suggest that national governments should aim to establish trust when engaging communities to change behavior during epidemics. Further research on the relationship between trust and epidemics may serve to improve epidemic response efficacy and behavior uptake.

Triangulating Evidence to Infer Pathways that Influence Ebola Virus Disease-Related Stigma and Clinical Findings among Survivors: An Observational Cohort Study.

Visible signs of disease can evoke stigma while stigma contributes to depression and mental illness, sometimes manifesting as somatic symptoms. We assessed these hypotheses among Ebola virus disease (EVD) survivors, some of whom experienced clinical sequelae. Ebola virus disease survivors in Liberia were enrolled in an observational cohort study starting in June 2015 with visits every 6 months. At baseline and 18 months later, a seven-item index of EVD-related stigma was administered. Clinical findings (self-reported symptoms and abnormal findings) were obtained at each visit. We applied the generalized estimating equation method to assess the bidirectional concurrent and lagged associations between clinical findings and stigma, adjusting for age, gender, educational level, referral to medical care, and HIV serostatus as confounders. When assessing the contribution of stigma to later clinical findings, we restricted clinical findings to five that were also considered somatic symptoms. Data were obtained from 859 EVD survivors. In concurrent longitudinal analyses, each additional clinical finding increased the adjusted odds of stigma by 18% (95% CI: 1.11, 1.25), particularly palpitations, muscle pain, joint pain, urinary frequency, and memory loss. In lagged associations, memory loss (adjusted odds ratio [AOR]: 4.6; 95% CI: 1.73, 12.36) and anorexia (AOR: 4.17; 95% CI: 1.82, 9.53) were associated with later stigma, but stigma was not significantly associated with later clinical findings. Stigma was associated with select symptoms, not abnormal objective findings. Lagged associations between symptoms and later stigma substantiate the possibility of a pathway related to visible symptoms identified by community members and leading to fear of contagion.

Knowledge, Attitude and Practice of Sudanese Health Care Providers toward Ebola Virus Outbreak.

Ebola virus disease (EVD) is a highly contagious and fatal disease in humans. Healthcare providers (HCPs) are often at the frontline of epidemics and can thus be in jeopardy of contracting EVD. Sudan is at a great risk of an EVD outbreak, as it borders countries that experienced EVD outbreaks. It is therefore imperative in Sudan to assess the HCPs' awareness and knowledge, attitude, and practice (KAP) about EVD for its control and man-agement and for preparedness. A KAP survey was conducted among 387 HCPs (physicians, nurses and labora-tory technicians) in the three main tertiary hospitals in Khartoum, Sudan. The majority of the survey respon-dents (54.5%) were females, < 30 years old (76.3%), and single (77.4%). Most (94%) had heard about EVD, 62% from classical media. Only 14% had received education or training regarding EVD. About 40% reported being adherent to universal precautions and 72% were willing to deal with EVD patients under safety precau-tions. Only 10% knew of any available standard national guidelines for EVD. Nearly half of the HCPs (47%) rated the potential risk of an EVD outbreak in Sudan as high, and 52% rated health authorities' effort against it as weak. These findings revealed the HCPs' insufficient knowledge of EVD and the necessary universal precau-tions. This lack of knowledge would negatively affect the HCPs' preparedness toward any potential EVD out-break. There is a dire need to train HCPs in Sudan on the management of EVD, including preventive and con-trol measures.

Non-epistemic values in shaping the parameters for evaluating the effectiveness of candidate vaccines: the case of an Ebola vaccine trial.

This paper examines the case of Ebola, ça Suffit trial which was conducted in Guinea during Ebola Virus Disease (EVD) outbreak in 2015. I demonstrate that various non-epistemic considerations may legitimately influence the criteria for evaluating the efficacy and effectiveness of a candidate vaccine. Such non-epistemic considerations, which are social, ethical, and pragmatic, can be better placed and addressed in scientific research by appealing to non-epistemic values. I consider two significant features any newly developed vaccine should possess; (1) the duration of immunity the vaccine provides; and (2) safety with respect to the side effects of the vaccine. Then, I argue that social and ethical values are relevant and desirable in setting the parameters for evaluating these two features of vaccines. The parameters that are employed for setting up the criteria for assessing the features might have far-reaching implications on the well-being of society in general, and the health conditions of several thousand people in particular. The reason is that these features can play a decisive role during the evaluation of the efficacy and effectiveness of the vaccine. I conclude by showing why it is necessary to reject the concept of epistemic priority, at least when scientists engage in policy-oriented research.

What We Have Learned from Two Decades of Epidemics and Pandemics: A Systematic Review and Meta-Analysis of the Psychological Burden of Frontline Healthcare Workers.

In light of the current coronavirus disease 2019 (COVID-19) pandemic and potential future infectious disease outbreaks, a comprehensive understanding of the negative effects of epidemics and pandemics on healthcare workers' mental health could inform appropriate support interventions. Thus, we aimed to synthesize and quantify the psychological and psychosomatic symptoms among frontline medical staff. We searched four databases up to March 19, 2020 and additional literature, with daily search alerts set up until October 26, 2020. Studies reporting psychological and/or psychosomatic symptoms of healthcare workers caring for patients with severe acute respiratory syndrome, H1N1, Ebola, Middle East respiratory syndrome, or COVID-19 were eligible for inclusion. Two reviewers independently conducted the search, study selection, quality appraisal, data extraction, and synthesis and involved a third reviewer in case of disagreement. We used random effects modeling to estimate the overall prevalence rates of psychological/psychosomatic symptoms and the I2 statistic. We included 86 studies, reporting data from 75,991 participants. Frontline staff showed a wide range of symptoms, including concern about transmitting the virus to the family (60.39%, 95% CI 42.53-76.96), perceived stress (56.77%, 95% CI 34.21-77.95), concerns about own health (45.97%, 95% CI 31.08-61.23), sleeping difficulties (39.88%, 95% CI 27.70-52.72), burnout (31.81%, 95% CI 13.32-53.89), symptoms of depression (25.72%, 95% CI 18.34-33.86), symptoms of anxiety (25.36%, 95% CI 17.90-33.64), symptoms of posttraumatic stress disorder (24.51%, 95% CI 18.16-31.46), mental health issues (23.11%, 95% CI 15.98-31.10), and symptoms of somatization (14.68%, 95% CI 10.67-19.18). We found consistent evidence for the pervasive and profound impact of large-scale outbreaks on the mental health of frontline healthcare workers. As the CO-VID-19 crisis continues to unfold, guaranteeing easy access to support structures for the entire healthcare workforce is vitally important.

Exploring health-seeking behavior among adolescent mothers during the Ebola epidemic in Western rural district of Freetown, Sierra Leone.

BACKGROUND: From 2014 to 2016, the largest Ebola outbreak in history threatened Sierra Leone and its neighbouring countries, Guinea and Liberia. The Ebola outbreak impacted pregnant adolescent girl's access to prenatal care during the pandemic. The aim of this study is to understand health-seeking behaviour among adolescent mothers who were pregnant during the Ebola epidemic in Waterloo, Sierra Leone. METHODS: The present qualitative study uses the "Three Delay" model, as a theoretical framework to understand and explore adolescent mother's health-seeking behaviour through four focus group discussions with five participants in each discussion group. The data were analysed using thematic analysis. RESULTS: A multitude of challenges were identified following the Ebola epidemic. The fear of contracting Ebola was a common reason for not seeking care or utilising services. This notion was perpetuated by perceptions in the community and participants personal experiences. Quarantines, national lockdowns, roadblocks, loss of income and extreme poverty were also identified as barriers to accessing health facilities during Ebola. The different encounters with health workers and the challenges that arose at the health facilities were subsequently additional discouraging factors influencing participant's decision not to seek health care. CONCLUSION: Many of the pre-existing maternal health, societal and social-economic challenges were exacerbated during the Ebola. The epidemic also contributed new challenges such as public fear, mistrust towards health professionals and the health system. Greater emphasis needs to be placed on improving maternal care in general, but also improving preparedness for maternal care in case of future outbreaks, especially for the most vulnerable groups such as adolescent mothers.

Knowledge, attitudes, and behaviors of healthcare professionals at the start of an Ebola virus epidemic.

INTRODUCTION: In August 2018 the Ministry of Health of the Democratic Republic of Congo (DRC) declared the 10th epidemic of Ebola virus disease (EVD) in a context of armed conflict and high population mobility. We aimed to assess the knowledge, attitudes, and practices of healthcare professionals related to this disease. METHOD: Descriptive and cross-sectional study conducted by self-administered questionnaires among a random sample of 455 healthcare professionals of the city of Butembo, eastern DRC. RESULTS: Healthcare professionals were mostly informed about this epidemic by the radio (72.2%). They were usually aware of the disease etiology (65.3%), contamination modes (78.2%), epidemiological surveillance objectives (89%), but they were much less familiar with its clinical outcome (37.9%) and with contact tracing (44.8%). Adequate attitudes and practices were observed in 44.3% of cases for hygiene and sanitation measures, 64.8% of cases for healthcare-associated infection prevention, and 39.7% of cases for the management of probable cases of EVD. CONCLUSION: At the start of an Ebola outbreak, capacity building for epidemiological surveillance, hospital hygiene, and safety of care should be among the first urgent actions to implement.

One novel virus, different beliefs as playmakers towards disease spread in Africa: looking at COVID-19 from a religious lens.

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.

[Epidemic emergencies and social stigma. Which lessons should we learn from SARS and Ebola epidemics for the current CoViD-19 pandemics?] / Emergenze epidemiche e stigma sociale. Quali insegnamenti trarre dalle precedenti epidemie di SARS ed Ebola da applicare nell'attuale pandemia CoViD-19?

Scientific literature produced during the most recent international epidemic emergencies, such as SARS and Ebola, highlights that infected persons are often labeled, rejected, discriminated and subjected to loss of status due to their perceived link with the disease. Such experiences of discrimination may have detrimental effects on both patients, their family members, friends and communities. It is also possible that those who have been infected with COVD-19 may experience shame, guilt and sense of isolation arising from social stigma. It is therefore important to take full advantage of experiences gained during past epidemic crises, in order to implement timely measures to tackle this further negative consequence of the pandemic.

'We have a role to play:' American Sierra Leoneans communicating the impact of the Ebola virus locally and across the diaspora.

OBJECTIVE: The aim of this study was to examine New Jersey Sierra Leoneans' experiences, perceptions, and knowledge about the Ebola outbreak to better understand how to serve diaspora communities during disease outbreaks and improve international community engagement efforts. STUDY DESIGN: Five focus groups were conducted with a total of 34 members of a New Jersey Sierra Leonean community. A short demographic survey was also administered. METHODS: Focus groups were audio-taped, transcribed, and then analyzed using QSR NVIVO. Demographic data were analyzed using SPSS. RESULTS: Major themes emerged from the focus groups as related to the Ebola outbreak: (1) stigma and discrimination; (2) psycho-socio-economic impact; and (3) public health communication challenges. CONCLUSIONS: Novel findings reveal the impact of the Ebola virus on a West African diaspora community in the United States. These findings also advance existing literature. Diaspora communities are an underutilized resource in international disease education, management and prevention outreach research. It is vital that health professionals begin to find effective ways to fold them into relief efforts.

Who's afraid of Ebola? Epidemic fires and locative fears in the Information Age.

Epidemics have traditionally been viewed as the widespread occurrence of infectious disease within a community, or a sudden increase above what is typical. But modern epidemics are both more and less than the diffusion of viral entities. We argue that epidemics are 'fire objects', using a term coined by Law and Singleton: They generate locative fears through encounters that focus attention on entities that are unknown or imprecisely known, transforming spaces and humans into indeterminate dangers, alternating appearance and absence. The Ebola epidemic of 2014 had more complex impacts than the number of infections would suggest. We employ multi-sited qualitative interviews to argue that locative fear is the essence of modern global epidemics. In the discussion we contrast Ebola with both the Zika epidemic that followed and the ongoing coronavirus (COVID-19) pandemic.

Evidence of behaviour change during an Ebola virus disease outbreak, Sierra Leone.

OBJECTIVE: To evaluate changes in Ebola-related knowledge, attitudes and prevention practices during the Sierra Leone outbreak between 2014 and 2015. METHODS: Four cluster surveys were conducted: two before the outbreak peak (3499 participants) and two after (7104 participants). We assessed the effect of temporal and geographical factors on 16 knowledge, attitude and practice outcomes. FINDINGS: Fourteen of 16 knowledge, attitude and prevention practice outcomes improved across all regions from before to after the outbreak peak. The proportion of respondents willing to: (i) welcome Ebola survivors back into the community increased from 60.0% to 89.4% (adjusted odds ratio, aOR: 6.0; 95% confidence interval, CI: 3.9-9.1); and (ii) wait for a burial team following a relative's death increased from 86.0% to 95.9% (aOR: 4.4; 95% CI: 3.2-6.0). The proportion avoiding unsafe traditional burials increased from 27.3% to 48.2% (aOR: 3.1; 95% CI: 2.4-4.2) and the proportion believing spiritual healers can treat Ebola decreased from 15.9% to 5.0% (aOR: 0.2; 95% CI: 0.1-0.3). The likelihood respondents would wait for burial teams increased more in high-transmission (aOR: 6.2; 95% CI: 4.2-9.1) than low-transmission (aOR: 2.3; 95% CI: 1.4-3.8) regions. Self-reported avoidance of physical contact with corpses increased in high but not low-transmission regions, aOR: 1.9 (95% CI: 1.4-2.5) and aOR: 0.8 (95% CI: 0.6-1.2), respectively. CONCLUSION: Ebola knowledge, attitudes and prevention practices improved during the Sierra Leone outbreak, especially in high-transmission regions. Behaviourally-targeted community engagement should be prioritized early during outbreaks.
