The NTDs programme of Liberia is among the first to implement an integrated approach and evaluate its impact. Methods A retrospective study of three of five CM-NTDendemic counties that implemented the integrated approach was compared with cluster-matched counties with nonintegrated CM-NTD. We compared trends in CM-NTD integrated versus non-integrated county clusters. We conducted a pre-post comparison of WHO high-level outcomes using data collected during intervention years compared with baseline in control counties. Changes in health outcomes, effect sizes for different diseases and rate ratios with statistically significant differences were determined. Complementary qualitative research explored CM-NTD stakeholders' perceptions, analysed through the framework approach, which is a transparent, multistage approach for qualitative thematic interdisciplinary data analysis. Results The detection rates for all diseases combined improved significantly in the intervention compared with the control clusters. Besides leprosy, detection rates improved with large effects, over fourfold increase with statistically significant effects for individual diseases (p<0.000; 95% CI 3.5 to 5.4). Access to CM-NTD services increased in integrated counties by 71 facilities, compared with three facilities in nonintegrated counties. Qualitative findings highlight training and supervision as inputs underpinning increases in case detection, but challenges with refresher training, medicine supply and incentives negatively impact quality, equity and access. Conclusions Integrating CM-NTDs improves case detection, accessibility and availability of CM-NTD services, promoting universal health coverage. Early case detection and the quality of care need further strengthening.

In Liberia, the national neglected tropical disease (NTD) programme supports health systems strengthening for case management of NTDs. Integration of NTD commodities into the national health system supply chain is central to the integrated approach; however, there is minimal evidence on enablers and barriers. Drawing on qualitative evaluation data, we illustrate that perceived benefits and strengths to integrating NTD commodities into the supply chain include leveraged storage and management capacities capitalized at lower system levels; the political will to integrate based on cost-saving and capacity strengthening potential and positive progress integrating paper-based reporting tools. Challenges remain, specifically the risk of reliance on donor funding; difficulty in accessing commodities due to bureaucratic bottlenecks; lack of inclusi...

Global health actors have recognized that Sustainable Development Goal 3:3 is only achievable through an integrated inter and intra-sectoral response. This study evaluated existing case detection and referral approaches in Liberia, utilizing the findings to develop and test an Optimal Model for integrated community-based case detection, referral, and confirmation. Finally, this study evaluates the efficacy of implementing the Optimal Model in improving the early diagnosis of NTDs.Methodology/Principal FindingsThe study used mixed methods, including key informant interviews, focus group discussions, participant observation, quantitative analysis, and reflexive sessions to evaluate the implementation of an Opti...

Solid evidence exists for an increased risk for individuals living in close contact with leprosy patients but the existence of zoonotic leprosy, environmental reservoirs and trauma-related transmission has also been established. To assess the current state of knowledge on M. leprae transmission, we conducted a systematic review of the peer-reviewed literature pertaining to this topic. Major electronic bibliographic databases were searched for relevant peer-reviewed articles published up to January 2014. No restrictions on study types, participants and location were applied, and all outcomes demonstrated to contribute to the transmission of M. leprae were considered. Included studies were grouped by mode of transmission, namely (i) human-to-human via aerosols or direct contact; (ii) direct inoculation (e.g. injury); and (iii) transmission to humans from environmental or zoonotic reservoirs, and by insects. The importance of the different transmission pathways and the strength of the evidence were assessed considering the number of publications describing similar findings, the consistency of the findings and the methodological quality of the studies. A total of 79 relevant articles were retained out of 3,805 hits resulting from the application of the search strategy. Solid evidence for transmission among contacts exists, and for zoonotic leprosy in the southern States of the USA. Based on the extant evidence, skin-to-skin contact, aerosols/droplets and shedding of bacteria into the environment and subsequent infection, e.g. through dust or small wounds, all remain possible options. No study has unequivocally demonstrated the mechanisms by which M. leprae bacteria travel from one case of leprosy to another.

This was accelerated by the London Declaration on NTDs in January 2012. Work on NTDs has expanded worldwide and many countries have set up NTD control and elimination programs. However, the work has focussed disproportionately on preventive treatment. There is an urgent need for more attention and resources to work with people with NTDrelated morbidity and disability. A lot can be gained in the fight against NTDs by combining knowledge and experience from cross-cutting fields. For this reason a workshop was organized bringing together scientists, experts and practitioners from different NTD backgrounds to explore options for cross-cutting strategies, interventions and research in the field of NTDs, particularly focusing on issues related to morbidity management and disability, in the broadest sense. The workshop produced an inventory of cross-cutting issues, an overview of knowledge gaps and research questions, proposals for pilot (research) projects and a list of recommendations. One of the main recommendations is based on the need for baseline data: to review existing indicators used for monitoring and surveillance of NTD-related morbidity and disability in order to identify common indicators that can be shared across NTDs.

Furthermore, there is a void of research about the experience of people with disabilities following diagnosis with HIV. Little is known about how HIV diagnosis intersects with disability and gender and how it shapes the experiences of intimacy and gender roles of those negotiating this intersection.Objective: The objective of this study was to explore how HIV, disability and gender shape the perspectives of HIV-positive women with disabilities regarding intimacy and gender roles.Methods: Twelve women in Lusaka, Zambia were recruited for in-depth semi-structured interviews to explore their experiences of having a disability and living with HIV. Interviews were conducted in English, Bemba, Nyanja and Zambian sign language. Descriptive and thematic analyses were conducted, followed by in-depth gende...

Simultaneously, the WHO neglected tropical disease (NTD) roadmap 2021–2030 calls for increased country ownership and domestically financed NTD programmes. Focusing on Liberia and blending primary research from the COUNTDOWN consortium and personal programmatic experience, this commentary reflects on the sustainability and financing of NTD programme delivery within the current context. We explore the successes and challenges of current models of collaboration and opportunities to improve country ownership and sustainability.
