Water, sanitation and hygiene (WASH) are critical in the prevention and care for all of the 17 neglected tropical diseases (NTDs) scheduled for intensified control or elimination by 2020.
Provision of safe water, sanitation and hygiene is one of the five key interventions within the global NTD ...roadmap. Yet to date, the WASH component of the strategy has received little attention and the potential to link efforts on WASH and NTDs has been largely untapped.
Focused efforts on WASH are urgently needed if the global NTD roadmap targets are to be met. This is especially needed for NTDs where transmission is most closely linked to poor WASH conditions such as soil-transmitted helminthiasis, schistosomiasis, trachoma and lymphatic filariasis.
This strategy aims to mobilise WASH and NTD actors to work together towards the roadmap targets.

This toolkit for integrated vector management (IVM) is designed to help national and regional programme managers coordinate across sectors to design and run large IVM programmes.
The toolkit provides the technical detail required to plan, implement, monitor and evaluate an IVM approach. IVM can... be used when the aim is to control or eliminate vector-borne diseases and can also contribute to insecticide resistance management. This toolkit provides information on where vector-borne diseases are endemic and what interventions should be used, presenting case studies on IVM as well as relevant guidance documents for reference.
The diseases that are the focus of this toolkit are malaria, lymphatic filariasis, dengue, leishmaniasis, onchocerciasis, human African trypanosomiasis and schistosomiasis. It also includes information on other viral diseases (Rift Valley fever, West Nile fever, Chikungunya, yellow fever) and trachoma. If other vector-borne diseases appear in a country or area, vector control with an IVM approach should be adopted, as per national priorities.

his first edition describes the standard operating procedures for health products for NTDs amenable to preventive chemotherapy and the medicines donated to treat them. These include albendazole for lymphatic filariasis and soil-transmitted helminthiases; azithromycin for trachoma and yaws; diethylca...rbamazine citrate for lymphatic filariasis; ivermectin for onchocerciasis and lymphatic filariasis; mebendazole for soil-transmitted helminthiases; praziquantel for schistosomiasis; and triclabendazole for foodborne trematodiases. Standard operating procedures for diseases amenable to case management will be covered in subsequent editions, including the application process for requesting medicines (Chapter 1). In the meantime, the procedures described in the rest of the document apply for both case management and preventive chemotherapy NTD health products.

Many countries have made significant progress in the implementation of World Health Organization recommended preventive chemotherapy strategy, to eliminate lymphatic filariasis (LF). However, pertinent challenges such as the existence of areas of residual infections in disease endemic districts pose... potential threats to the achievements made. Thus, this study was undertaken to assess the importance of these areas in implementation units (districts) where microfilaria (MF) positive individuals could not be found during the mid-term assessment after three rounds of mass drug administration.

Mapping is a prerequisite for effective implementation of interventions against neglected tropical diseases (NTDs). Before the accelerated World Health Organization (WHO)/Regional Office for Africa (AFRO) NTD Mapping Project was initiated in 2014, mapping efforts in many countries were frequently ca...rried out in an ad hoc and nonstandardized fashion. In 2013, there were at least 2,200 different districts (of the 4,851 districts in the WHO African region) that still required mapping, and in many of these districts, more than one disease needed to be mapped. During its 3-year duration from January 2014 through the end of 2016, the project carried out mapping surveysfor one ormore NTDs in at least 2,500 districts in 37 African countries. At the end of 2016, most (90%) of the 4,851 districts had completed the WHO-required mapping surveys for the five targeted Preventive Chemotherapy (PC)-NTDs, and the impact of this accelerated WHO/AFRO NTD Mapping Project proved to be much greater than just the detailed mapping results themselves. Indeed, the AFRO Mapping
Project dramatically energized and empowered national NTD programs, attracted donor support for expanding these programs, and developed both a robust NTD mapping database and data portal. By clarifying the prevalence and burden
of NTDs, the project provided not only the metrics and technical framework for guiding and tracking program implementation and success but also the research opportunities for developing improved diagnostic and epidemiologic sampling tools for all 5 PC-NTDs—lymphatic filariasis, onchocerciasis, schistosomiasis, soil-transmitted helminthiasis, and trachoma.

Formation sur le suivi et l’évaluation épidémiologique du traitement médicamenteux de masse pour l’élimination de la filariose lymphatique : guide des apprenants. Organisation mondiale de la Santé.
La filariose lymphatique (FL) est une maladie évitable, incapacitante et défigurante, due à une infestation par des filaires parasites des espèces Wuchereria bancrofti, Brugia malayi et B. timori. On estime que 51,4 millions de personnes sont infectées dans le monde. Le lymphœdème et l’hydr...ocèle sont les conséquences cliniques chroniques visibles de l’altération des vaisseaux lymphatiques causée par la présence de
ces parasites dans l’organisme. Les parasites sont transmis d’une personne à l’autre par l’intermédiaire de moustiques des genres Culex, Anopheles, Mansonia et Aedes. L’année 2020 a marqué la 20e année du Programme mondial pour l’élimination de la filariose lymphatique (GPELF) établi par l’OMS, dont l’objectif est de mettre fin à la transmission de l’infection grâce à l’administration de masse de médicaments
(AMM) et d’alléger les souffrances des malades par la prise en charge de la morbidité et la prévention des incapacités (PMPI).

Background: The human helminth infections include ascariasis, trichuriasis, hookworm infections, schistosomiasis, lymphatic filariasis (LF) and onchocerciasis. It is estimated that almost 2 billion people worldwide are infected with helminths. Whilst the WHO treatment guidelines for helminth infecti...ons are mostly aimed at controlling morbidity, there has been a recent shift with some countries moving towards goals of disease elimination through mass drug administration, especially for LF and onchocerciasis. However, as prevalence is driven lower, treating entire populations may no longer be the most efficient or cost-effective strategy. Instead, it may be beneficial to identify individuals or demographic groups who are persistently infected, often termed as being “predisposed” to infection, and target treatment at them.
Methods: The authors searched Embase, MEDLINE, Global Health, and Web of Science for all English language, humanbased papers investigating predisposition to helminth infections published up to October 31st, 2017. The varying definitions used to describe predisposition, and the statistical tests used to determine its presence, are summarised. Evidence for predisposition is presented, stratified by helminth species, and risk factors for predisposition to infection are identified and discussed.
Results: In total, 43 papers were identified, summarising results from 34 different studies in 23 countries. Consistent evidence of predisposition to infection with certain species of human helminth was identified. Children were regularly found to experience greater predisposition to Ascaris lumbricoides, Schistosoma mansoni and S. haematobium than adults. Females were found to be more predisposed to A. lumbricoides infection than were males. Household clustering of infection was identified for A. lumbricoides, T. trichiura and S. japonicum. Ascaris lumbricoides and T. trichiura also showed evidence of familial predisposition. Whilst strong evidence for predisposition to hookworm infection was identified, findings with regards to which groups were affected were considerably more varied than for other helminth species.
Conclusion: This review has found consistent evidence of predisposition to heavy (and light) infection for certain human helminth species. However, further research is needed to identify reasons for the reported differences between demographic groups. Molecular epidemiological methods associated with whole genome sequencing to determine ‘who infects whom’ may shed more light on the factors generating predisposition.

South Sudan has a high burden – among the highest in sub-Saharan Africa – of neglected tropical diseases (NTDs). This adversely affects the health and social and economic well-being of people in the country. The prevention, control and eventual elimination of many NTDs depend heavily on improved... access to water, sanitation and hygiene (WASH) and, once there is access, on sound sanitation and hygiene practices. This is especially the case in NTD endemic communities.
The main NTDs prevalent in South Sudan include lymphatic filariasis, schistosomiasis (bilharzia), soiltransmitted helminths (STH), onchocerciasis, trachoma, leishmaniasis and Guinea-worm disease.
While the Ministry of Health (MoH) of South Sudan, through its NTD programme, had prioritized NTD/WASH partnerships and collaboration to improve the national NTD response, the programme lacked resources, capacity and a technical framework to lead the development of a harmonized NTD/WASH communication strategy.

Un suivi et une évaluation efficaces sont nécessaires pour atteindre l’objectif d’élimination de la filariose lymphatique (FL). Après le traitement médicamenteux de masse (TMM) conformément aux lignes directrices élaborées par l’OMS, des programmes doivent être mis en œuvre afin de d...éterminer si les interventions ont permis de réduire la prévalence de l’infestation à un niveau en deçà duquel sa transmission ne pourra vraisemblablement pas perdurer. L’enquête d’évaluation
de la transmission (TAS) a été conçue de manière à offrir une structure simple et robuste afin de déterminer si la prévalence de la filariose lymphatique chez des enfants de 6–7 ans est inférieure à un seuil préalablement déterminé. Le TAS fournit aux administrateurs de programmes les informations factuelles nécessaires pour décider de l’opportunité d’arrêter le TMM. Le TAS garantit aux pouvoirs publics que les programmes nationaux ont atteint leur objectif d’élimination de la FL.
Ce guide a été conçu pour enseigner aux membres du personnel des programmes nationaux d’élimination de la FL, notamment le personnel de santé aux niveaux régional et de district, les éléments essentiels des programmes nationaux de suivi et d’évaluation pour l’élimination de la FL. Le guide est axé sur la planification et la mise en œuvre du TAS afin de pouvoir décider de l’opportunité
d’interrompre le TMM et de commencer la surveillance post-TMM.
