Key populations (KPs) are particularly vulnerable to HIV infection and efforts to prevent HIV infections among KPs have been less successful, largely due to existing laws and legislation that classify the groups as illegal. Understanding the HIV infection pathway and the burden of HIV infection among Female Sex Workers (FSWs), Transgender people (TG), Men who have sex with Men (MSM), People who Inject Drugs (PWID), and Prison Inmates (PIs) is critical to combatting the HIV epidemic globally. This study aims to estimate HIV prevalence and model the risk factors of HIV positivity rate among the aforementioned KPs in Sierra Leone. This study used Time Location Sampling, Respondent Driven Sampling (RDS), and Conventional cluster Sampling designs to generate a representative sample of FSWs, MSM, TG, PI, and PWID. HIV prevalence and the corresponding 95% confidence intervals among each KP were estimated by adjusting for sampling weight using the logit-transformed confidence intervals. To determine correlates of HIV test positivity among KPs, a multivariable modified Poisson regression model that adjusts for RDS survey weights was used and sensitivity analysis was conducted using a multivariable logistic regression model with cluster robust standard errors. The prevalence of HIV among FSWs in the six regional headquarter towns was estimated to be 11.8% (95% CI: 7.9–17.1); MSM was 3.4% [95% CI: 1.9–5.8]; TGs was 4.2% (95% CI: 2.9–6.1); PWIDs was 4.2% (95% CI: 2.7–6.4) and PI was 3.7% (95% CI: 1.4–9.6). The correlates of HIV test positivity among KPs and PIs include HIV-related knowledge, marital status, district, income, age and sex of KP, level of education, alcohol intake, injecting drugs, and use of lubricants. HIV prevalence is relatively high among FSWs, MSMs, PWID, and TGs as compared to the previous estimate of the general population. There is a need to scale up and strengthen evidence-based HIV prevention interventions such Pre-Exposure Prophylaxis and needle and syringe exchange programmes targeting KPs, including prison inmates. Government must scale up both non-clinical and clinical routine HIV and STI testing and counseling services at the correctional center and drop-in centers for KPs screening/testing, and ensure that services are responsive to the needs of KP.

The social vulnerability of the Yemeni population to humanitarian emergencies is not evenly distributed between the governorates. Some governorates may be more susceptible to the impacts than others, based on the circumstances of the people residing within them. In this paper, we present a methodology for assessing social vulnerability of governorates of Yemen to humanitarian emergencies using a Geographic Information Systems approach. We develop a spatial index of social vulnerability from an initial list of 80 variables that were reduced to 12 factors through Principal Component Analysis. Our findings show that the differences in social vulnerability between governorates are primarily driven by 12 factors, of which education, lack of basic services in health, water and sanitation, electricity, housing quality, poverty, limited livelihood opportunities, and internal and external displacement are the major determinants. The results show that the factors that contribute to social vulnerability are different for each governorate, underpinning the need for context-specific vulnerability reduction approaches. The most vulnerable governorates are characterized by conflicts, armed clashes and violence. The geographic variability in social vulnerability further underpins the need for different mitigation, humanitarian response and recovery actions. The use of Geographic Information Systems approach has contributed to our understanding of the geographies of vulnerability to humanitarian emergencies in Yemen.

BackgroundLittle is known about strategies for optimising the scale and deployment of community health workers (CHWs) to maximise geographic accessibility of primary healthcare services.MethodsWe used data from a national georeferenced census of CHWs and other spatial datasets in Sierra Leone to undertake a geospatial analysis exploring optimisation of the scale and deployment of CHWs, with the aim of informing implementation of current CHW policy and future plans of the Ministry of Health and Sanitation.ResultsThe per cent of the population within 30 min walking to the nearest CHW with preservice training increased from 16.1% to 80.4% between 2000 and 2015. Contrary to current national policy, most of this increase occurred in areas within 3 km of a health facility where nearly two-thirds (64.5%) of CHWs were deployed. Ministry of Health and Sanitation-defined ‘easy-to-reach’ and ‘hard-to-reach’ areas, geographic areas that should be targeted for CHW deployment, were less well covered, with 19.2% and 34.6% of the population in 2015 beyond a 30 min walk to a CHW, respectively. Optimised CHW networks in these areas were more efficiently deployed than existing networks by 22.4%–71.9%, depending on targeting metric.InterpretationsOur analysis supports the Ministry of Health and Sanitation plan to rightsize and retarget the CHW workforce. Other countries in sub-Saharan Africa interested in optimising the scale and deployment of their CHW workforce in the context of broader human resources for health and health sector planning may look to Sierra Leone as an exemplar model from which to learn.

Since 2004, twice-yearly mass vitamin A supplementation (VAS) has equitably reached over 85 % of children 6–59 months old in Sierra Leone. However infants who turn 6 months after the event may wait until they are 11 months old to receive their first dose. The effectiveness of integrating VAS at 6 months into the Expanded Program of Immunization (EPI) in a revised child health card was studied. Health facilities matched according to staff cadre and work load were assigned to provide either a ‘mini package’ of VAS and infant and young child feeding (IYCF), a ‘full package’ of VAS, IYCF and family planning (FP), or ‘child health card’ only. 400 neonates were enrolled into each group, caregivers given the new child health card and followed until they were 12 months old. More infants in the full: 74.5 % and mini: 71.7 % group received VAS between 6 and 7 months of age compared with the new CH card only group: 60.2 % ( p  = 0.002, p  < 0.001 respectively). FP commodities were provided to 44.5 % of caregivers in the full compared with <2.5 % in the mini and new child health card only groups ( p  < 0.0001). Integration of VAS within the EPI schedule achieved >60 % coverage for infants between 6 and 7 months of age. Provision of FP and/or IYCF further improved coverage. Funding was provided by the Canadian Department of Foreign Affairs, Trade and Development who had no role in study design, data collection and analysis, decision to publish or preparation of the manuscript.

The role of community health workers (CHWs) in the West Africa Ebola outbreak has been highlighted to advocate for increasing numbers of CHWs globally to build resilience, strengthen health systems, and provide emergency response capacity. However, the roles CHWs played, the challenges they faced, and their effectiveness during the outbreak are not well documented. This study assessed the impact of Ebola on community-based maternal, newborn, and child health (MNCH) services, documented the contribution of CHWs and other community-based actors to the Ebola response, and identified lessons learned to strengthen resilience in future emergencies.BACKGROUNDThe role of community health workers (CHWs) in the West Africa Ebola outbreak has been highlighted to advocate for increasing numbers of CHWs globally to build resilience, strengthen health systems, and provide emergency response capacity.

By the end of the Ebola epidemic, death reporting in Sierra Leone (SL) became more acceptable amongst local populations, with nearly all deaths being reported to the Ebola hot line alert centers. To continue the positive momentum generated by the epidemic, the Sierra Leone Ministry of Health and Sanitation (MoHS) and the US Centers for Disease Control and Prevention (CDC) organized and conducted the two-day Inter-agency Consultations on Improving Mortality Reporting in Sierra Leone (Consultations). In conjunction with the Consultations, participants were also offered a one-day, in-person training on the major components, characteristics, and uses of a national Civil Registration and Vital Statistics (CRVS) system. To understand processes used by governmental and non-governmental organizations in collection of death data before and during the Ebola epidemic, and to develop recommendations on improving death reporting and CRVS in Sierra Leone. The Inter-agency Consultations were conducted in person over two days in October, 2015. Real-time notes were kept by CDC staff for later abstraction and summarizing. Presenters agreed to share their materials (usually PowerPoint presentations) and approved the summaries. Challenges to implementation and suggestions for improving death reporting were drawn from the presentations and from anonymous suggestions collected at the end of each of three days of the Consultations. The Consultations attracted more than 80 participants from 28 Sierra Leone governmental, business, and other non-governmental organizations. Over the course of 18 presentations, participants presented and discussed the ways deaths were reported before and during the Ebola epidemic and ways in which the CRVS in Sierra Leone might be improved. The presentations made clear the need to improve death reporting in order to improve the health status of Sierra Leone. Many presenters and participants discussed the challenges to improvements, including lack of infrastructure and country diversity. In addition, participants generally agreed upon the need for improving the government’s understanding of the benefits of death reporting at multiple levels: from local chiefdom authorities and councils to the community and individual families. Despite the many challenges identified, all participants stressed the need for modernizing and improving death registration in Sierra Leone. The recommendations from the presentations and notes collected at the end of each day can be categorized within the following five domains: capacity building (organizational, staffing, infrastructure, policies, guidelines and tools), awareness and sensitization (including strategies to use best practices and emerging technologies), political will (governmental support and prioritization), funding (providing resources to achieve sustainability), and monitoring and evaluation (developing charts of existing death reporting pathways and identifying challenges).

The purpose of this study was to determine the relationships between the performance of OCES agricultural agents and their educational, occupational and selected demographic characteristics. Technical and supportive academic courses, length, and number of positions of prior work experience, area of program specialization, tenure, grade point average, and areas of responsibility were the independent variables. Supervisor rated scores, and agents' self-rated scores were used to determine the levels of the dependent variables. Methodology. All Ohio county agents in agriculture made up the target population, N = 76. The sample size was 54 with usable data from 44. The study was descriptive/correlational. Data were collected from OCES records and by mail questionnaire. Findings. The agents were not significantly different on either supervisor rated or agents' self-rated job performance ratings with regard to: credit hours of technical agriculture and credit hours of supportive courses, length, and number of positions of professional work experience, tenure in extension, grade point average, program area of specialization, and numbers of program areas of responsibility. Conclusion. Agents' job performance was not influenced by any of the independent variables. To emphasize technical agriculture courses over supportive courses is not supported by this study. Extensive training does not hinder job performance. To expect job performance improvements or adverse effects from longer periods of prior work experience, higher grade point average, particular program areas of specialization, longer tenure in current agent position, and higher numbers of program area of responsibility was not supported by the findings. Flexibility in implementing employment policies, and programs affected by the occupational and educational background of agents should be considered.
