INTRODUCTION
Between 2020 and 2021, MSF’s social sciences team designed and supported implementation of qualitative assessments to better understand community-level outbreak responses and well-being in the context of Covid-19. Assessments were conducted in seven sites, specifically Nigeria, Sierra Leone, Chad, Iraq, Tajikistan, Syria, and Somaliland. Although a single protocol was designed and followed, each site was unique in terms of its setting (e.g. camp, conflict, urban, or rural), who implemented assessments (e.g. field epidemiologists, health promotion staff), timing of implementation (early phase of the pandemic versus late phase), and community involvement. Here we present a synthesis of the assessments to inform future public health responses.
METHODS
Synthesis involved secondary analysis of qualitative reports over five iterative phases. Phase 1 involved in-depth reading of each report, during which analytic annotation and note-taking took place. In Phase 2, each report was coded inductively. In Phase 3, codes were reviewed, defined, and clustered into initial categories and themes. Phase 4 involved reviewing and refining codes, categories, and themes, and establishing connections. In Phase 5, synthesis findings were organised and written up. The process was managed using the software ATLAS.ti.
ETHICS
This synthesis is an a posteriori analysis of secondary data. Ethics approval for primary data was granted by officials in Nigeria, Sierra Leone, Chad, Iraq, Tajikistan, Syria, and Somaliland and the MSF Ethics Review Board.
RESULTS
Overall 138, people participated in the assessments, of which 21 (15%) were women. Participants included health workers, community members, traditional healers, chiefs, young people, women’s leaders and local staff. Four themes were identified: 1) exacerbation of pre-existing vulnerabilities and inequalities; 2) disruption of coping mechanisms; 3) awareness of the risks of Covid-19; 4) community as a public health enabler. The pandemic was seen to magnify existing social inequalities and overall health burden. Public health measures to control the spread of Covid-19 often disrupted community coping mechanisms by causing fear of separation and practical challenges around compliance. Awareness of the risks of Covid-19 and understanding of prevention measures were high, with socio-economic costs of compliance relying on external funding and relief. A community led intervention for effective public health controls varied between sites, depending on previous outbreak experiences (e.g. Ebola and tuberculosis), and/or settings experiencing protracted conflict (e.g. Syria, and Iraq).
CONCLUSION
Our synthesis illustrates syndemic effects of the pandemic. From an operational perspective, there is a need to diversify humanitarian, social, and health interventions, and strengthen approaches to working with communities to identify how best to take forward public health measures in humanitarian settings.

Little is understood of Ebola virus disease (EVD) transmission dynamics and community compliance with control measures over time. Understanding these interactions is essential if interventions are to be effective in future outbreaks. We conducted a mixed-methods study to explore these factors in a rural village that experienced sustained EVD transmission in Kailahun District, Sierra Leone.

Between August-December 2014, Ebola Virus Disease (EVD) patients from Tonkolili District were referred for care to two Médecins Sans Frontières (MSF) Ebola Management Centres (EMCs) outside the district (distant EMCs). In December 2014, MSF opened an EMC in Tonkolili District (district EMC). We examined the effect of opening a district-based EMC on time to admission and number of suspect cases dead on arrival (DOA), and identified factors associated with fatality in EVD patients, residents in Tonkolili District. Residents of Tonkolili district who presented between 12 September 2014 and 23 February 2015 to the district EMC and the two distant EMCs were identified from EMC line-lists. EVD cases were confirmed by a positive Ebola PCR test. We calculated time to admission since the onset of symptoms, case-fatality and adjusted Risk Ratios (aRR) using Binomial regression. Of 249 confirmed Ebola cases, 206 (83%) were admitted to the distant EMCs and 43 (17%) to the district EMC. Of them 110 (45%) have died. Confirmed cases dead on arrival (n = 10) were observed only in the distant EMCs. The median time from symptom onset to admission was 6 days (IQR 4,8) in distant EMCs and 3 days (IQR 2,7) in the district EMC (p<0.001). Cases were 2.0 (95%CI 1.4-2.9) times more likely to have delayed admission (>3 days after symptom onset) in the distant compared with the district EMC, but were less likely (aRR = 0.8; 95%CI 0.6-1.0) to have a high viral load (cycle threshold ≤22). A fatal outcome was associated with a high viral load (aRR 2.6; 95%CI 1.8-3.6) and vomiting at first presentation (aRR 1.4; 95%CI 1.0-2.0). The opening of a district EMC was associated with earlier admission of cases to appropriate care facilities, an essential component of reducing EVD transmission. High viral load and vomiting at admission predicted fatality. Healthcare providers should consider the location of EMCs to ensure equitable access during Ebola outbreaks.

Background: On 14 August 2017, massive landslides and floods hit Freetown (Sierra Leone). More than 1,000 people lost their lives while approximately 6,000 people were displaced. The areas most affected included parts of the town with challenged access to basic water and sanitation facilities, with communal water sources likely contaminated by the disaster. To avert a possible cholera outbreak following this emergency, the Ministry of Health and Sanitation (MoHS), supported by the World Health Organization (WHO) and international partners, including Médecins Sans Frontières (MSF) and UNICEF, launched a two-dose pre-emptive vaccination campaign using Euvichol™, an oral cholera vaccine (OCV).
Methods: We conducted a stratified cluster survey to estimate vaccination coverage during the OCV campaign and also monitor adverse events. The study population - subsequently stratified by age group and residence area type (urban/rural) - included all individuals aged 1 year or older, living in one of the 25 communities targeted for vaccination.
Results: In total 3,115 households were visited, 7,189 individuals interviewed; 2,822 (39%) people in rural and 4,367 (61%) in urban areas. The two-dose vaccination coverage was 56% (95% confidence interval (CI): 51.0-61.5), 44% (95%CI: 35.2-53.0) in rural and 57% (95%CI: 51.6-62.8) in urban areas. Vaccination coverage with at least one dose was 82% (95%CI: 77.3-85.5), 61% (95%CI: 52.0-70.2) in rural and 83% (95%CI: 78.5-87.1) in urban areas.
Conclusions: The Freetown OCV campaign exemplified a timely public health intervention to prevent a cholera outbreak, even if coverage was lower than expected. We hypothesised that vaccination coverage in Freetown was sufficient in providing at least short-term immunity to the population. However, long-term interventions to ensure access to safe water and sanitation are needed.
