La quincuagésima primera Asamblea de la Salud Mundial aprobó la resolución WHA51.11 en
1998, que busca la eliminación mundial del tracoma como problema de salud pública para el 2020
(1). La estrategia recomendada para lograr ese objetivo está encapsulada por las siglas "SAFE", que
represent...a: La cirugía para los individuos con triquiasis tracomatosa (TT; la última etapa que causa
ceguera por tracoma); y Antibióticos, Limpieza Facial y Mejoramiento ambiental (2). Las
intervenciones A, F y E se llevan a distritos enteros en los que el tracoma activo (inflamatorio) es
común para tratar la infección ocular causada por Chlamydia trachomatis, el agente causal del
tracoma y reduce de manera sustentable su transmisión.

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.

Rabies is fatal, vaccine-preventable disease responsible for an estimated 59,000 human deaths each year. Most cases are transmitted by dogs, and most deaths occur in underserved populations in Africa and Asia. Approximately 40% of deaths occur in children.

Yaws is a chronic skin infection characterized by papillomas (noncancerous lumps) and ulcers. It is caused by the bacterium Treponema pallidum subspecies pertenue, which belongs to the same group of bacteria that causes venereal syphilis.
Onchocerciasis – or “river blindness” – is a parasitic disease caused by the filarial worm Onchocerca volvulus transmitted by repeated bites of infected blackflies (Simulium spp.). These blackflies breed along fast-flowing rivers and streams, close to remote villages located near fertile lan...d where people rely on agriculture.

As part of its 2019–2030 global strategy for the prevention and control of snakebite envenoming, WHO is launching a new Snakebite Information and Data Platform. This is the result of collaboration between the Departments of Control of Neglected Tropical Diseases (WHO/NTD) and Data Delivery for Imp...act & Analytics (WHO/DDI).
With support from the WHO GIS Centre for Health, the platform is developed with a new generation of ArcGIS software. It comprises advanced tools for managing, analyzing, and visualizing updated multi-sourced data, providing an interactive and participative user experience. It includes updated range maps of all medically important venomous snakes, other relevant information, and an integrated antivenom products database.

The document explains why vector control is important in national programmes and describes the preparation of a tailor-made vector control plan for national programmes. It outlines entomological procedures for regular and specific vector control and how data should be analysed for better overall und...erstanding of filarial transmission and vectors. The document will also be useful for teaching personnel in lymphatic filariasis programmes about the use and value
of entomological procedures in overall epidemiological appraisal in the context of

Un comité OMS d’experts sur la trypanosomiase humaine africaine (THA) : lutte et surveillance, s’est réuni à Genève (Suisse), du 22 au 26 avril 2013. Le Dr H. Nakatani, sous-directeur général pour le VIH/SIDA, la tuberculose, le paludisme et les maladies tropicales négligées, a ouvert la... réunion au nom du Dr M. Chan, directeur-général de l’OMS.
La THA est une maladie qui afflige les populations rurales de l’Afrique, là où prolifère la mouche tsé-tsé (ou glossine), vecteur des trypanosomes qui en sont la cause. On distingue deux formes de THA : la forme à T. b. gambiense ou forme gambienne, endémique en Afrique de l’Ouest et en Afrique centrale et qui
représente actuellement 95 % des cas, et la forme à T. b. rhodesiense ou forme rhodésienne, endémique en Afrique de l’Est et en Afrique australe, à laquelle sont dus les 5 % restants.

Leptospirosis is an infectious disease caused by pathogenic organisms belonging to the genus Leptospira, that are transmitted directly or indirectly from animals to humans. Leptospirosis is a major direct zoonosis. Humanto-human transmission occurs only very rarely.
Skin-related neglected tropical diseases, or “skin NTDs”, are historically neglected because active case detection, individual case management, significant resources and intensive effort are required to control, eliminate and eradicate them. Integrated control and management of skin NTDs offers ...a pathway to overcome some of these past challenges.

The Leprosy Programme and Transmission Assessment (LPTA) is an activity that is carried out by internal teams towards the end of Phase 1 (see Leprosy Elimination Framework in the Annex) when a subnational jurisdiction (typically second-tier) reaches the milestone for interruption of transmission, i....e., zero autochthonous child cases for a consecutive period of five years. It also needs to be done at the end of Phase 2, when the second milestone of elimination of leprosy disease has been reached. An LPTA will be carried out to document that all relevant programme criteria have been met and examine trends of epidemiological indicators in such jurisdiction to confirm that the milestone has been achieved. The LPTA includes assessment of health facilities that provide leprosy services. LPTA comprises of review of epidemiological data, health facility assessment and data validation and verification of the programme criteria through observation during a field visit. The evidence collected in this way in subnational health administrative units is compiled in a Leprosy Elimination Dossier to be submitted to WHO when the country reaches the milestone for elimination of disease in the country as whole. Countries that have not detected any new leprosy cases in the past three years or more can use the LPTA at national level prior to or as part of the verification process. Countries likely to be among the first to apply for verification may have had no new cases detected for more than 10 years.

La esquistosomiasis es una enfermedad parasitaria aguda y crónica causada por duelas sanguíneas (trematodos) del género Schistosoma. Se calcula que al menos 251,4 millones de personas necesitaron tratamiento profiláctico en 2021. El tratamiento profiláctico, que se debería repetir durante algu...nos años, permite reducir y prevenir la morbilidad. Hay constancia de la transmisión de la enfermedad en 78 países. Sin embargo, la quimioprofilaxis para la esquistosomiasis, en la que se aplica un tratamiento a gran escala a personas y comunidades, solamente se requiere en 51 países en los que la enfermedad es endémica y tienen una transmisión de moderada a alta.

Map of Distribution of opisthorchiasis, worldwide, latest year available.
Foodborne trematodes are a group of diseases that include the parasites Clonorchis, Opisthorchis, Fasciola and Paragonimus. These parasitic flukes have a complex life cycle involving diverse definitive hosts and one or two i...ntermediate hosts. Foodborne trematodes cause infection in humans via the consumption of contaminated food (raw fish, crustaceans or vegetables). Infection can result in severe liver and lung disease and together these diseases are estimated to cause 2 million life years lost to disability and death worldwide every year.

The main purpose of the meeting was to review tsetse control tools, activities and their contribution to the elimination of gHAT and the monitoring thereof. Seven endemic countries provided reports on recent and ongoing vector control interventions at the national level (Angola, Cameroon, Côte d’...Ivoire, Chad, Democratic Republic of the Congo, Guinea and Uganda). Country reports focused on the in situations implementing and supporting vector control activities, the tools and the approaches in use, the coverage of the activities in space and time and their impacts on tsetse populations. Future perspectives for vector control in the respective countries were also discussed, including opportunities and challenges to sustainability.
