Using Passive Surveillance to Maintain Elimination as a Public Health Problem for Neglected Tropical Diseases: A Model-Based Exploration.

BACKGROUND: Great progress is being made toward the goal of elimination as a public health problem for neglected tropical diseases such as leprosy, human African trypanosomiasis, Buruli ulcer, and visceral leishmaniasis, which relies on intensified disease management and case finding. However, strategies for maintaining this goal are still under discussion. Passive surveillance is a core pillar of a long-term, sustainable surveillance program. METHODS: We use a generic model of disease transmission with slow epidemic growth rates and cases detected through severe symptoms and passive detection to evaluate under what circumstances passive detection alone can keep transmission under control. RESULTS: Reducing the period of infectiousness due to decreasing time to treatment has a small effect on reducing transmission. Therefore, to prevent resurgence, passive surveillance needs to be very efficient. For some diseases, the treatment time and level of passive detection needed to prevent resurgence is unlikely to be obtainable. CONCLUSIONS: The success of a passive surveillance program crucially depends on what proportion of cases are detected, how much of their infectious period is reduced, and the underlying reproduction number of the disease. Modeling suggests that relying on passive detection alone is unlikely to be enough to maintain elimination goals.

An Ensemble Framework for Projecting the Impact of Lymphatic Filariasis Interventions Across Sub-Saharan Africa at a Fine Spatial Scale.

BACKGROUND: Lymphatic filariasis (LF) is a neglected tropical disease targeted for elimination as a public health problem by 2030. Although mass treatments have led to huge reductions in LF prevalence, some countries or regions may find it difficult to achieve elimination by 2030 owing to various factors, including local differences in transmission. Subnational projections of intervention impact are a useful tool in understanding these dynamics, but correctly characterizing their uncertainty is challenging. METHODS: We developed a computationally feasible framework for providing subnational projections for LF across 44 sub-Saharan African countries using ensemble models, guided by historical control data, to allow assessment of the role of subnational heterogeneities in global goal achievement. Projected scenarios include ongoing annual treatment from 2018 to 2030, enhanced coverage, and biannual treatment. RESULTS: Our projections suggest that progress is likely to continue well. However, highly endemic locations currently deploying strategies with the lower World Health Organization recommended coverage (65%) and frequency (annual) are expected to have slow decreases in prevalence. Increasing intervention frequency or coverage can accelerate progress by up to 5 or 6 years, respectively. CONCLUSIONS: While projections based on baseline data have limitations, our methodological advancements provide assessments of potential bottlenecks for the global goals for LF arising from subnational heterogeneities. In particular, areas with high baseline prevalence may face challenges in achieving the 2030 goals, extending the "tail" of interventions. Enhancing intervention frequency and/or coverage will accelerate progress. Our approach facilitates preimplementation assessments of the impact of local interventions and is applicable to other regions and neglected tropical diseases.

The Hidden Hand of Asymptomatic Infection Hinders Control of Neglected Tropical Diseases: A Modeling Analysis.

BACKGROUND: Neglected tropical diseases are responsible for considerable morbidity and mortality in low-income populations. International efforts have reduced their global burden, but transmission is persistent and case-finding-based interventions rarely target asymptomatic individuals. METHODS: We develop a generic mathematical modeling framework for analyzing the dynamics of visceral leishmaniasis in the Indian sub-continent (VL), gambiense sleeping sickness (gHAT), and Chagas disease and use it to assess the possible contribution of asymptomatics who later develop disease (pre-symptomatics) and those who do not (non-symptomatics) to the maintenance of infection. Plausible interventions, including active screening, vector control, and reduced time to detection, are simulated for the three diseases. RESULTS: We found that the high asymptomatic contribution to transmission for Chagas and gHAT and the apparently high basic reproductive number of VL may undermine long-term control. However, the ability to treat some asymptomatics for Chagas and gHAT should make them more controllable, albeit over relatively long time periods due to the slow dynamics of these diseases. For VL, the toxicity of available therapeutics means the asymptomatic population cannot currently be treated, but combining treatment of symptomatics and vector control could yield a quick reduction in transmission. CONCLUSIONS: Despite the uncertainty in natural history, it appears there is already a relatively good toolbox of interventions to eliminate gHAT, and it is likely that Chagas will need improvements to diagnostics and their use to better target pre-symptomatics. The situation for VL is less clear, and model predictions could be improved by additional empirical data. However, interventions may have to improve to successfully eliminate this disease.

Global Dilemma and Needs Assessment Toward Achieving Sustainable Development Goals in Controlling Leishmaniasis.

Leishmaniasis is a disease of poverty that imposes a devastating medical, social, and economic burden on over 1 billion people nationwide. To date, no in-depth study to analyze the major global challenges and needs assessment has been carried out. This investigation aimed to explore a comprehensive narrative review of leishmaniasis's main challenges and initially highlight obstacles that might impede the implementation of control measures. Also, we propose a specific list of priorities for needs assessment. The presence of socioeconomic factors, multiple clinical and epidemiological forms, various Leishmania species, the complexity of the life cycle, the absence of effective drugs and vaccines, and the lack of efficient vector and reservoir control make this organism unique and sophisticated in playing a tangled role to react tricky with its surrounding environments, despite extensive efforts and implementation of all-inclusive former control measures. These facts indicate that the previous strategic plans, financial support, and basic infrastructures connected to leishmaniasis surveillance are still insufficient. Strengthening the leishmaniasis framework in a context of accelerated programmatic action and intensification of cross-cutting activities along with other neglected tropical diseases (NTDs) is confidently expected to result in greater effectiveness, cost-benefit, and fruitful management. Sensitive diagnostics, effective therapeutics, and efficacious vaccines are vital to accelerating advancement toward elimination, and reducing morbidity/mortality and program costs. Collective actions devoted by all sectors and policy-makers can hopefully overcome technical and operational barriers to guarantee that effective and coordinated implementation plans are sustained to meet the road map for NTDs 2021- 2030 goals.

Prevalence, assessment and correlates of mental health problems in neglected tropical diseases: a systematic review.

Neglected tropical diseases (NTDs) are a group of disease conditions that affect the world's poorest people in low- and middle-income countries. NTDs are associated with negative behavioural experiences, including discrimination, rejection and stigmatization, that predisposes those affected to mental health problems. Consequently, researchers have shown profound interest in elucidating the mental health burden associated with NTDs. To address pertinent issues in the burgeoning literature relating to the prevalence, assessment and correlates of mental health problems in NTDs, a systematic review methodology was used. Underpinned by the PRISMA guidelines, a search was conducted of electronic databases, individual journals and bibliographies for articles that were screened and subjected to predetermined inclusion and exclusion criteria. Sixteen articles from African, Asian and South American countries were included in the review. Depression was the most widely investigated mental health issue, followed by stress and anxiety, with prevalence estimates of 7-54%, 8-43% and 19-53%, respectively. The PHQ-9 and GAD-7 and Self-Reporting Questionnaire were the most widely administered mental health screening tools. The major correlates of mental health problems are lower education and economic status and female gender. We recommend multisectoral and multilayered mental health and related interventions to address the increasing burden of mental health in NTDs.

A spiking fever.

Long neglected, Lassa fever is surging in West Africa. Researchers want to know why.

Control, elimination, and eradication efforts for neglected tropical diseases in the World Health Organization African region over the last 30 years: A scoping review.

OBJECTIVES: NTDs historically receive less attention than other diseases in the same regions. Recent gap analyses revealed notable shortcomings despite NTD elimination progress. This systematic scoping review was conducted to understand NTD control, elimination, and eradication efforts in the WHO African region over the last 30 years. METHODS: Peer-reviewed publications from PubMed, Web of Science, and Cochrane databases related to NTD control, elimination, and eradication in the WHO African Region from 1990 to 2022 were reviewed. Included articles were categorized based on NTD; study location, type, and period; and topic areas. Technical and guidance documents from WHO, UN, partner, and academic/research institutions were reviewed. Country-specific multi-year NTD master plans were documented. RESULTS: Four hundred eighty peer-reviewed articles, six Cochrane reviews, and 134 technical reports were included. MDA and non-interventional/survey-related studies were common topics. Lymphatic filariasis, trachoma, schistosomiasis, and onchocerciasis were the most frequently studied NTDs. Tanzania, Ethiopia, and Nigeria were the most represented countries; multi-country studies were limited. CONCLUSION: The review highlights progress made in NTD control, elimination, and eradication efforts in the WHO African Region and can inform national/regional strategies. Disease and geographical disparities were evident, warranting focus and research in certain countries. A standardized approach to NTD control programs is needed for sustained progress. FUNDING: There was no funding source for this study.

Neglected tropical disease (NTD) diagnostics: current development and operations to advance control.

Neglected tropical diseases (NTDs) have become important public health threats that require multi-faceted control interventions. As late treatment and management of NTDs contribute significantly to the associated burdens, early diagnosis becomes an important component for surveillance and planning effective interventions. This review identifies common NTDs and highlights the progress in the development of diagnostics for these NTDs. Leveraging existing technologies to improve NTD diagnosis and improving current operational approaches for deployment of developed diagnostics are crucial to achieving the 2030 NTD elimination target. Point-of-care NTD (POC-NTD) diagnostic tools are recommended preferred diagnostic options in resource-constrained areas for mapping risk zones and monitoring treatment efficacy. However, few are currently available commercially. Technical training of remote health care workers on the use of POC-NTD diagnostics, and training of health workers on the psychosocial consequences of these diagnostics are critical in harnessing POC-NTD diagnostic potential. While the COVID-19 pandemic has challenged the possibility of achieving NTD elimination in 2030 due to the disruption of healthcare services and dwindling financial support for NTDs, the possible contribution of NTDs in exacerbating COVID-19 pandemic should motivate NTD health system strengthening.

Mental health and neglected tropical diseases - the neglected dimension of burden: identifying the challenges and understanding the burden.

Mental health co-morbidity and the Neglected Tropical Diseases (NTDs) has been highlighted as a major component of the ill health. The impact of mental illness is considered to be significantly underestimated in the calculations of the overall Disability-Adjusted Life Years (DALYs). This commentary discusses the DALY burden of anxiety, depression and associated stigma of NTDs. The economic losses incurred as a result of mental health conditions is assessed, and the impact on caregivers and families. It recommends that mental health care is incorporated into NTDs programme planning and implementation. Priority research is the estimation of the NTD burden of depressive and anxiety disorders and neuropsychiatric conditions of NTDs and an evaluation of the economic costs of mental illness derived from NTDs causation.

Stigma, depression and quality of life among people affected by neglected tropical diseases in Nepal.

BACKGROUND: Stigma and poor mental health are important factors influencing the quality of life (QOL) of people with neglected tropical diseases (NTDs). This study examines the relationship between stigma, depression and QOL among people affected by leprosy and lymphatic filariasis (LF) in Nepal. METHODS: A cross-sectional community-based survey was conducted among 102 NTD-affected persons (70 leprosy and 32 LF) using interview-administered questionnaires measuring the level of stigma (5-QSI-AP), symptoms of depression (PHQ-9) and QOL (WHOQOL-8). Three different regression models were developed, each using the ordinary least squares and Poisson regression to evaluate the association between stigma and QOL, depression and QOL, and stigma and depression. RESULTS: The mean scores were 21.8±4.4 for QOL, 6.6±5.6 for depression and 3.0±2.8 for stigma. Almost 17% reported the prevalence of depression symptoms. Both stigma (ß=-0.65, p<0.001) and depression (ß=-0.32, p<0.001) were associated with lower scores for QOL, while there was a significant positive relationship between stigma and depression (ß=0.92, p<0.001). Similar results were obtained from the Poisson regression models. CONCLUSIONS: The study showed a considerable burden of depression, stigma and poor QOL among study participants with leprosy and LF in Nepal. A holistic package of care that addresses the physical, mental and psychological well-being of people with NTD is required. CONTEXTE: La stigmatisation et la mauvaise santé mentale sont des facteurs importants qui influencent la qualité de vie des personnes atteintes de maladies tropicales négligées (MTN). Cette étude examine la relation entre la stigmatisation, la dépression et la qualité de vie chez les personnes atteintes de lèpre et de filariose lymphatique au Népal. MÉTHODES UTILISÉES: Une enquête communautaire transversale a été menée auprès de 102 personnes atteintes de MTN (70 de la lèpre et 32 de la filariose lymphatique) à l'aide de questionnaires administrés par entretien mesurant le niveau de stigmatisation (5-QSI-AP), les symptômes de dépression (PHQ-9) et la qualité de vie (WHOQOL-8). Trois modèles de régression différents ont été développés, chacun utilisant les moindres carrés ordinaires et la régression de Poisson pour évaluer l'association entre : (i) la stigmatisation et la QV; (ii) la dépression et la QV; et (iii) la stigmatisation et la dépression. RÉSULTATS: Les scores moyens étaient de 21,8±4,4 pour la QV, 6,6±5,6 pour la dépression, et 3,0±2,8 pour la stigmatisation. Près de 17% des personnes interrogées ont signalé la prévalence de symptômes dépressifs. La stigmatisation (ß = -0,65, p<0 001) et la dépression (ß = -0,32, p<0 001) ont été associées à des scores plus faibles pour la qualité de vie, tandis qu'il existait une relation positive significative entre la stigmatisation et la dépression (ß = 0,92, p<0 001). Des résultats similaires ont été obtenus à partir des modèles de régression de Poisson. CONCLUSIONS: L'étude a montré une incidence importante de dépression, de stigmatisation et d'une mauvaise qualité de vie parmi les participants atteints de lèpre et de FL au Népal. Il convient donc de mettre en place un ensemble de soins holistiques pour ces patients qui prendrait en compte le bien-être physique, mental et psychologique des personnes atteintes de MTN. ANTECEDENTES: La estigmatización y la mala salud mental son factores importantes que influyen en la calidad de vida de las personas con enfermedades tropicales desatendidas. las personas con enfermedades tropicales desatendidas (ETD). Este estudio examina la relación entre el estigma, la depresión y la CdV entre las personas afectadas por lepra y lepra y la filariasis linfática en Nepal. MÉTODOS: Se realizó una encuesta comunitaria transversal entre 102 personas afectadas por ETD (70 de lepra y 32 de filariasis linfática) utilizando cuestionarios entrevistas para medir el nivel de estigma (5-QSI-AP), los síntomas de depresión (PHQ- 9) y la CdV (OMS- 9). 9) y la calidad de vida (WHOQOL-8). Se desarrollaron tres modelos de regresión diferentes regresión de Poisson para evaluar la asociación entre: (i) el estigma y (ii) la depresión. entre: (i) estigma y CdV; (ii) depresión y CdV; y (iii) estigma y depresión. RESULTADOS: Las puntuaciones medias fueron 21,8±4,4 para la CdV, 6,6±5,6 para la depresión y 3,0±2,8 para el estigma. Casi el 17% informó de la prevalencia de síntomas de depresión. Tanto el estigma (ß = -0,65, p<0 001), como la depresión (ß = -0,32, p<0 001) se asociaron con puntuaciones más bajas para la CdV, mientras que hubo una relación positiva significativa entre el estigma y la depresión (ß = 0,92, p<0 001). Se obtuvieron resultados similares en los modelos de regresión de Poisson. CONCLUSIONES: El estudio mostró una carga considerable de depresión, estigma y mala CdV entre los participantes del estudio con lepra y FL en Nepal. Se requiere un paquete holístico de atención que aborde el bienestar físico, mental y psicológico de las personas con ETD.

Integration of services for Neglected Tropical Diseases and mental health in Nigeria: development of a practical model informed by international recommendations, contextual factors and service-user perspectives.

BACKGROUND: Mental health care is now recognised as essential for people affected by NTDs, but accessible services are rare. This paper presents results of a prevalence study for depression and anxiety among people living with leprosy and lymphatic filariasis, and collation of user perspectives on needs and priorities for a new service. METHODS: Prevalence of mental conditions was carried out with 141 people living with leprosy and lymphatic filariasis and matched controls. Those who screened positive for depression or anxiety were interviewed in a qualitative study to understand their experiences of living with the conditions, and what their priorities would be for services and support. Results contributed to the process of developing a contextually adapted collaborative care model for implementation in the primary care system in Nigeria, using a Theory of Change approach. RESULTS: We found high rates of depression, anxiety, and reduced wellbeing, with strong correlation across measures. The qualitative study revealed experiences of stigma and exclusion, and concern for financial and economic needs, and a desire for provision of free services and support for livelihoods. CONCLUSION: Services should be designed with good understanding of local needs and service user priorities. CONTEXTE: Les soins de santé mentale sont désormais reconnus comme essentiels pour les personnes touchées par les MTN, mais les services accessibles sont rares. Cet article présente les résultats d'une étude de prévalence de la dépression et de l'anxiété chez les personnes vivant avec la lèpre et la filariose lymphatique, ainsi que la collecte des points de vue des utilisateurs sur les besoins et les priorités d'un nouveau service.

Mental health, stigma and the quality of life of people affected by neglected tropical diseases of the skin in Kasai Province, Democratic Republic of the Congo: a sex-disaggregated analysis.

BACKGROUND: Worldwide, persons affected by skin Neglected Tropical Diseases (NTDs) may experience stigma and discrimination, which could lead to impaired societal functioning and poor mental wellbeing. Evidence of comorbidity of NTDs and mental health conditions is dominated by Leprosy, largely lacking in post-conflict areas, and rarely disaggregated by sex. METHODS: This cross-sectional survey is the first to explore depression, anxiety, stigma, and quality of life amongst people affected by Lymphatic Filariasis, Buruli Ulcer, Onchocerciasis or Leprosy in the Democratic Republic of the Congo. After a census through active case identification, the survey was completed by 118 persons (response rate 94.4%). RESULTS: In total, 58.3% of men and 80.0% of women screened positive for major depressive disorder (PHQ-9). Symptoms indicative of generalised anxiety disorder (GAD-7) were displayed by 54.8% of men and 62.2% of women. Being female, having a disability, experiencing stigma and lower physical quality of life were predictors of depression. Anxiety was predicted by age, physical quality of life, disability (for men only) and environmental quality of life (for women only). CONCLUSIONS: Integrated, intersectoral and gender-sensitive initiatives are needed to respond to the many biopsychosocial challenges that persons affected face. CONTEXTE: Dans le monde entier, les personnes atteintes de maladies tropicales négligées (MTN) peuvent faire l'objet d'une stigmatisation et d'une discrimination, ce qui peut entraîner une altération du fonctionnement de la société et un mauvais bien-être mental. Les preuves de la comorbidité des MTN et des troubles de la santé mentale sont dominées par la lèpre, manquent largement dans les zones post-conflit et sont rarement ventilées par sexe. MÉTHODES UTILISÉES: Cette enquête transversale est la première à explorer la dépression, l'anxiété, la stigmatisation et la qualité de vie chez les personnes atteintes de filariose lymphatique, d'ulcère de Buruli, d'onchocercose ou de lèpre en République démocratique du Congo. Après un recensement par identification active des cas, 118 personnes ont répondu à l'enquête (taux de réponse 94,4%). RÉSULTATS: Au total, 58,3% des hommes et 80,0% des femmes ont été dépistés positifs pour un trouble dépressif majeur (PHQ-9). Des symptômes indiquant un trouble anxieux généralisé (GAD-7) ont été observés chez 54,8 % des hommes et 62,2 % des femmes. Le fait d'être une femme, d'avoir un handicap, d'être stigmatisé et d'avoir une qualité de vie physique inférieure était un facteur prédictif de la dépression. L'anxiété était prédite par l'âge, la qualité de vie physique, le handicap (pour les hommes uniquement) et la qualité de vie environnementale (pour les femmes uniquement). CONCLUSIONS: Des initiatives intégrées, intersectorielles et sensibles au genre sont nécessaires pour répondre aux nombreux défis biopsychosociaux auxquels sont confrontées les personnes touchées. ANTECEDENTES: En todo el mundo, las personas afectadas por Enfermedades Tropicales Desatendidas (ETD) cutáneas pueden sufrir estigmatización y discriminación, lo que podría conducir a un deterioro del funcionamiento social y a un bienestar mental deficiente. La evidencia científica sobre la comorbilidad de las ETD y las afecciones mentales está dominada por la lepra, en general insuficiente en zonas post-conflicto y rara vez se desglosan por sexo. MÉTODOS: Esta encuesta transversal es la primera que explora la depresión, la ansiedad, el estigma y la calidad de vida entre las personas afectadas por la filariasis linfática, la úlcera de Buruli, la oncocercosis o la lepra en la República Democrática del Congo. Tras un censo mediante identificación activa de casos, la encuesta fue completada por 118 personas (tasa de respuesta del 94,4%). RESULTADOS: En total, el 58,3% de los hombres y el 80,0% de las mujeres arrojaron resultados positivos para el trastorno depresivo mayor (PHQ-9). El 54,8% de los hombres y el 62,2% de las mujeres presentaban síntomas indicativos de trastorno de ansiedad generalizada (TAG-7). Ser mujer, tener una discapacidad, sufrir estigmatización y una menor calidad de vida física fueron factores predictivos de la depresión. La edad, la calidad de vida física, la discapacidad (sólo en el caso de los hombres) y la calidad de vida ambiental (sólo en el caso de las mujeres) fueron factores predictivos de la ansiedad. CONCLUSIONES: Se necesitan iniciativas integradas, intersectoriales y con perspectiva de género para responder a los numerosos retos biopsicosociales a los que se enfrentan las personas afectadas.

A systematic review of neglected tropical diseases (NTDs) in Myanmar.

BACKGROUND: Neglected tropical diseases (NTDs) affect most impoverished communities in developing countries, like Myanmar in Southeast Asia. NTDs have been understudied and underreported in Myanmar. METHODS: A systematic review of published and grey literature (1900-2023) on neglected tropical diseases (NTDs) in Myanmar was conducted. The literature search included five international databases: PubMed, EMBASE, Ovid Global Health, and Web of Science Core Collection and one national database: the Myanmar Central Biomedical Library (locally published papers and grey literature). The selection criteria included articles with all types of study designs of current or previous infections conducted in humans, that reported NTDs, recognised by WHO, US CDC, and listed in PLoS NTDs. We included melioidosis and rickettsioses which we consider also meet the definition of an NTD. RESULTS: A total of 5941 records were retrieved and screened, of which, 672 (11%) met the selection criteria and were included in this review. Of the included articles, 449 (65%) were published after 2000 and 369 (55%) were from two regions (Yangon and Mandalay) of Myanmar. Of the included articles, 238 (35%) reported bacterial NTDs, 212 (32%) viral NTDs, 153 (23%) helminth NTDs, 25 (4%) protozoal NTDs and 39 (6%) reported more than one aetiology. Based on reported frequency in descending order, the bacterial NTDs were leprosy, Escherichia coli enteritis, salmonellosis, cholera, shigellosis, melioidosis, leptospirosis and rickettsioses; the viral NTDs were dengue, chikungunya and Japanese encephalitis virus (JEV) infection; the protozoal NTDs were amoebiasis, giardiasis and leishmaniasis, and the helminth NTDs were ascariasis, trichuriasis, hookworm disease, filariasis and strongyloidiasis. CONCLUSION: This review summarises NTDs reported in Myanmar over the past 100 years. The findings suggest that most NTDs are likely to be under reported, especially from the majority of the country which is far from academic centres. Research capacity building together with strengthening of laboratory systems would lead to better understanding of the true burden of NTDs in Myanmar.

Mycetoma and the environment.

Mycetoma is a chronic, incapacitating, destructive inflammatory disease with many serious damaging impacts. Currently, there is no control or prevention program as many of its epidemiological characteristics, such as the causative organisms' ecological niche, natural habitat, primary reservoir, transmission mode, geographical distribution, incidence, and prevalence, remain unclear. This may be due to a lack of research interest, as mycetoma is still a neglected disease and the scarcity of accurate molecular diagnostic techniques in disease-endemic regions for accurate causative microorganisms identification and mapping. With this background, this study set out to address this knowledge gap by considering the mycetoma environmental occurrence predictors. The medical literature obtained data showed a close association between mycetoma occurrence and its environment. The causative microorganisms are available in the environment in active or dormant forms. Animal dung may be a natural niche and reservoir for these organisms, and thorns may facilitate the subcutaneous inoculation. Some environmental factors, such as the soil type and consistency, temperature, water sources, aridity index, and thorny trees, may be risk factors. The population in endemic areas socioeconomic, hygiene, and health education status are contributory factors for mycetoma. The individual's genetic and immunological backgrounds may determine the disease's susceptibility and resistance. Environmental conditions and personal hygiene improvement are mandatory to reduce disease occurrence. Mycetoma spatial mapping can detect disease cluster areas and then develop public health strategies for early case detection and management to reduce the disease burden. More research interests and facilities are needed to understand disease pathogenesis and appropriate patient management better.

Healthcare Policies to Eliminate Neglected Tropical Diseases (NTDs) in India: A Roadmap.

The need for systemic healthcare policies to systematically eliminate NTDs globally and in India has been stressed for more than two decades. Yet, the present policies and the research on them do not meet the need. We present an ontological framework, a research roadmap, and a policy brief to address the gap. The ontology clearly, concisely, and comprehensively represents the combinations of diseases, the objectives regarding the diseases, the entities to address them, the outcomes sought, and the potential policy instruments to invoke. The paper explicates the state of the-policies and state of the research on policies to eliminate NTDs in India. It highlights the significant gaps in the diseases covered, balance in the objectives, comprehensiveness of policies, portfolio of outcomes, and involvement of entities. Last, it presents a set of systemic policies congruent with the ontology to systematically address the gaps. The recommendations are aligned with the present research, policies, practices, and recommendations in India and of the WHO, UN agencies, and other similar bodies. The approach can be generalized to provide roadmaps for other countries facing a similar challenge and for other diseases of similar complexity. The roadmaps, with continuous feedback and learning, can help navigate the challenge efficiently and effectively.
