Taeniasis and cysticercosis caused by the parasite T. solium affect vulnerable populations,
mainly in Latin America, sub-Saharan Africa and Asia, where pigs (the intermediate host) roam
free and poor sanitation allows pigs access to human faeces.
Taenia saginata is a zoonotic tapeworm that is of economic importance in countries where cattle are kept. The parasite is transmitted from human tapeworm carriers (taeniosis) to bovines (cysticercosis) by excretion of eggs or proglottids containing eggs into the environment via the stool. Bovines ca...n then ingest the eggs through contaminated feed or water. After ingestion, the eggs hatch and release oncospheres in the small intestines, where the oncospheres penetrate the intestinal wall to reach the blood circulation. This distributes them throughout the body, but primarily to muscle tissue, where they develop into cysticerci. For humans to become infected with T. saginata, raw or undercooked bovine meat or offal containing infective cysts must be consumed. Bovine cysticercosis has been associated with various environmental factors related to water sources, such as animals having access to surface water, flooding of pastures and proximity to wastewater sources.

Rabies is a disease of animals but too often the outcome is gauged in terms of human suffering and
death. Despite this, in areas of the world where rabies is endemic there is often a lack of communication between veterinary and medical professionals, to the extent that the disease continues to thri...ve and potential victims are not treated. The problem is partly
exacerbated by a lack of awareness and experience of the disease and of what to do when confronted by suspect cases. In these technologically advanced days, although it is possible to learn “all there is to know” about almost any subject, it is sometimes difficult to distil the essence.

En la actualidad, los daños que sufren los pacientes a causa de una atención poco segura constituyen un desafío
importante y creciente para la salud pública mundial y son una de las principales causas de muerte y discapacidad
en todo el mundo. La mayor parte de estos daños son evitables. Ahor...a que los países se esfuerzan por alcanzar la
cobertura sanitaria universal y los Objetivos de Desarrollo Sostenible, los efectos beneficiosos de un mayor acceso
a los servicios de atención de la salud pueden verse socavados por una atención poco segura. Los incidentes
relacionados con la seguridad de los pacientes pueden causar muerte y discapacidad, así como sufrimiento a
las víctimas y sus familias. Los costos económicos que conllevan los fallos de seguridad son elevados. A menudo
se reduce la confianza del público en los sistemas de salud locales cuando se dan a conocer estos accidentes.
El personal de salud implicado en sucesos graves que implican la muerte o un daño grave a un paciente
también puede sufrir un deterioro psicológico duradero y sentimientos de culpa y autocrítica muy arraigados

A medida que el tratamiento antirretrovírico con dolutegravir se extiende a más personas que viven con el VIH en el
mundo, adquiere más importancia estimar la frecuencia con que surge la farmacorresistencia adquirida a este
antirretrovírico en las poblaciones tratadas con esquemas que lo conti...enen. Si bien no se ha detectado resistencia
al dolutegravir en los ensayos clínicos con poblaciones no tratadas antes con antirretrovíricos en las que se ha
detectado una viremia persistente pese al tratamiento, los datos indican que puede surgir en quienes toman esquemas
con dolutegravir. La OMS recomienda a los países que estén ampliando el tratamiento con dolutegravir que acompañen
su despliegue con la vigilancia sistemática de la farmacorresistencia.

The epidemiology of the disease is mediated by the interaction of the parasite (trypanosome) with the vectors (tsetse flies), as well as with the human and animal hosts within a particular environment. Related to these interactions, the disease is confined in spatially limited areas called “foci..., which are located
in Sub-Saharan Africa, mainly in remote rural areas. The risk of contracting HAT is, therefore, determined by the possibility of contact of a human being with an infected tsetse fly. Epidemics of HAT were described at the beginning of the 20th century; intensive activities have been set up to confront the disease, and it was under control in the 1960s, with fewer than 5,000 cases reported in the whole continent.

This project aimed to reduce the risk of vector-borne infection with Chagas disease by
controlling triatomine bugs, the vectors transmitting the parasite of Chagas disease, and
establishing an epidemiological surveillance system with community participation.
This analysis focused on the chronic form of HAT caused by T. b. gambiense, as it contributes to the majority of disease burden. Information from the literature review,
product development landscape, and stakeholder interviews was compiled to:
- Identify use cases and understand current diagnosti...c practices and tools associated with each use case.
- Analyze progress toward robust diagnostics for HAT across different biomarkers.
- Develop recommendations for steps to improve the availability, access, and adoption of HAT diagnostic tools.

Les pays progressent vers la réalisation de l’objectif mondial tendant à ce que, d’ici 2025, 95 pour cent des personnes qui vivent avec le VIH connaissent leur statut sérologique. Cependant, en 2020, on estimait encore à 6 millions le nombre de personnes séropositives non diagnostiquées da...ns le monde. Les hommes vivant dans des lieux où la prévalence du VIH est élevée et les hommes appartenant aux populations clés, tous lieux confondus, ont moins de chances de connaître leur séropositivité que les femmes. Ainsi, au niveau mondial, 78 pour cent des hommes de plus de 15 ans connaissent leur statut sérologique, contre 86 pour cent chez les femmes de cette même tranche d’âge.

A wide spectrum of disease severity has been described for Human African Trypanosomiasis (HAT) due to
Trypanosoma brucei rhodesiense (T.b. rhodesiense), ranging from chronic disease patterns in southern countries of East Africa to an increase in virulence towards the north. However, only limited d...ata on the clinical presentation of T.b. rhodesiense HAT is available. From 2006-2009 we conducted the first clinical trial program (I MPAMEL III) in T.b. rhodesiense endemic areas of
Tanzania and Uganda in accordance with international standards (ICH-GCP). The primary and secondary outcome measures were safety and efficacy of an abridged melarsoprol schedule for treatment of second stage disease. Based on diagnostic findings and clinical examinations at baseline we describe the clinical presentation of T.b. rhodesiense HAT in second stage patients from two distinct geographical settings in East Africa.

The development of this target product profile (TPP) was led by the WHO Department of Control of Ne-
glected Tropical Diseases (NTD) following standard WHO guidance for TPP development. In order to
identify and prioritize diagnostic needs, a WHO NTD Diagnostics Technical Advisory Group (DTAG)
was... formed, and different subgroups were created to advise on specific NTDs, including a subgroup
working on the human African trypanosomiasis (HAT) diagnostic innovation needs. This group of in-
dependent experts included leading scientists, public health officials and endemic-country end-user rep-
resentatives. Standard WHO Declaration of Interest procedures were followed. A landscape analysis of
the available products and of the development pipeline was conducted, and the salient areas with unmet
needs were identified
