Guide; revised 15 June 2010
Ce rapport montre que d’importants progrès ont été accomplis en 2015 pour atteindre les cibles de la feuille de route. Ces résultats procèdent de la mise en œuvre de cinq interventions recommandées par l’OMS pour vaincre les MTN : chimiothérapie préventive ; prise en charge innovante et... intensifiée de la maladie ; écologie et gestion vectorielles ; services de santé publique vétérinaire ; et approvisionnement en eau sans risque sanitaire et services d’assainissement et d’hygiène.

dans le contexte de la pandémie de COVID-19
Soil-transmitted helminths are a group of intestinal worms that include Ascaris lumbricoides (giant roundworm), Trichuris trichiura (whipworm), and Ancylostoma spp. (A. duodenale, A. ceylanicum) and Necator americanus (hookworms). Despite the clear biological differences among the different species,... their transmission is characterized by the same sequence of events: (i) infected individuals excrete worm eggs through their stool in soil; (ii) under optimal conditions of moisture and temperature the excreted eggs develop into infectious stages; and (iii) finally, infection occurs through oral uptake (Ascaris, Ancylostoma and Trichuris) or skin penetration (Ancylostoma and Necator) of these infectious stages (embryonated eggs and third stage larvae) that reside in the soil and/or in the environment (referring to their common name).

Health ministries currently lack effective tools for monitoring and evaluation of schistosomiasis control programmes. Egg detection can be used, but the cost, challenges of obtaining samples, and the need for trained personnel and equipment limit the frequency of monitoring. The purpose of this TPP ...is to guide the development of new diagnostic tools to reliably measure when prevalence is above or below a cut-off of 10% in school-aged children. Communities remaining above 10% require annual MDA, while communities below 10% can reduce MDA frequency as long as < 10% prevalence can be maintained. However, the lack of a reliable test has hindered the development of maintenance strategies. The test is also needed to track changes of prevalence > 10% to ensure that annual MDA is reducing overall prevalence.

The 20th century was a period of unprecedented ecological change, with dramatic reductions in natural ecosystems and biodiversity and equally dramatic increases in people and domestic animals. Never before have so many animals been kept by so many people—and never before have so many opportunities... existed for pathogens to pass from wild and domestic animals through the biophysical environment to affect people causing zoonotic diseases or zoonoses. The result has been a worldwide increase in emerging zoonotic
diseases, outbreaks of epidemic zoonoses as well as a rise in foodborne zoonoses globally, and a troubling persistence of neglected zoonotic diseases in poor countries.

Chagas is a complex, multidimensional phenomenon in which political, economic, environmental, biomedical, epidemiological, psychological, and sociocultural factors intersect. Nonetheless, the hegemonic conceptualisation has long envisioned Chagas as primarily a biomedical question, while ignoring or... downplaying the other dimensions, and this limited view has reinforced the disease’s long neglect. Integrating the multiple dimensions of the problem into a coherent approach adapted to field realities and needs represents an immense challenge, but the payoff is more effective and sustainable experiences, with higher social awareness, increased case detection and follow-up, improved adherence to care, and integrated participation of various actors from multiple action levels. Information, Education, and Communication (IEC) initiatives have great potential for impact in the implementation of multidimensional programs of prevention and control successfully customised to the diverse and complex contexts where Chagas disease persists.

To support its R&D activities on Chagas disease, DNDi launched the Chagas Clinical Research Platform (CCRP). The platform brings together partners, experts, and stakeholders to provide support for evaluation and development of new treatments for Chagas disease. The patient-centred platform aims to f...acilitate clinical research, provide a forum for technical discussions, develop a critical mass of expertise, and strengthen institutional research capacities. In addition, it identifies and reviews priority needs, works towards standardization of methodology to assess drug efficacy and reviews alternatives for using current approved drugs (new schemes, doses, combination) and special scenarios (resistance).

Leishmaniasis is a climate-sensitive disease. Changes in
temperature, rainfall, and humidity can have strong impacts on
the sandfly vector, altering their distribution and influencing their
survival and population sizes. Increased temperatures shorten
vector development time, reduce Leishmania p...arasite incubation
time, and increase vector biting rates, allowing transmission
in areas not previously endemic for the disease. Poor and
marginalized communities will be hit disproportionately harder by
the effects of climate change, and droughts, famines, and floods
can also lead to displacement and migration of immunologically
naive people to areas where leishmaniasis is endemic, posing a
threat of leishmaniasis outbreaks.

إن دواء المشوكات البشري هو مرض طفيلي تتسبب به شريطيات من جنس الشريطيات المشوكة.
وأهم شكلين لهذا المرض لدى الإنسان هما داء المشوكات الكيسي ( داء التكيس ...لديداني) وداء المشوكات السنخي.
ويصاب الإنسان بالعدوى عبر ابتلاع بيوض الطفيليات في الأغذية، أو المياه، أو التربة الملوثة، أو من خلال الاحتكاك المباشر مع الحيوانات المضيفة.
وغالباً ما يكون علاج داء المشوكات مكلفاً ومعقداً، وقد يتطلب جراحة واسعة و/أو علاجاً دوائياً مطولا.
وتشمل برامج الوقاية إخضاع الكلاب لتدابير طرد الديدان، والنهوض بمعاينة الأغذية ونظافة المسالخ؛ ويجري حالياً تقييم تطعيم الحملان كتدخل إضافي.
وهناك أكثر من مليون مصاب بداء المشوكات في أي وقت من الأوقات.
ومرض داء المشوكات البشري هو مرض حيواني المصدر (أي ينتقل إلى الإنسان من الحيوان) تتسبب به طفيليات هي شريطيات من جنس المشوكات. ويظهر داء المشوكات في أربعة أشكال:

Despite pandemic-related disruptions, a total of 76.9 million people received treatment for schistosomiasis in 2020, representing a global coverage of 31.9%, compared with 105 million treated in 2019 (coverage of 44.8%).
The latest data published by the World Health Organization (WHO) show that 2...8.6 million fewer people were treated for schistosomiasis (bilharzia) in 2020 than in 2019. This 27% drop in the number of treatments delivered is largely due to the implementation of COVID-19 measures, including school closures.

La atención concedida a la equidad en la Agenda 2030 para el Desarrollo Sostenible obliga a encontrar nuevas formas de ampliar progresivamente los servicios a las poblaciones que no los reciben. Las alianzas satisfactorias entre el sector encargado del suministro de agua, el saneamiento y la higien...e (WASH, por su sigla en inglés) y los programas de lucha contra las enfermedades tropicales desatendidas (ETD) pueden contribuir a lograr esta aspiración. Sin embargo, colaborar para encontrar juntos esas nuevas formas, exige nuevos modos de pensar. En esta edición corregida se presenta un conjunto de herramientas para ayudar a los países y los programas de lucha contra la ETD a colaborar con la comunidad relacionada con las acciones de agua, saneamiento e higiene, y guía en la creación de alianzas, en la movilización de recursos y en el diseño, la aplicación y la evaluación de las intervenciones. Más que una guía de “buenas prácticas”, se trata de un conjunto de herramientas basadas en la experiencia adquirida en la realidad de un programa.
