This document provides up-to-date guidance on laboratory studies as well as smallscale (semi-field) and large-scale field trials to assess the efficacy and determine field
application rates of new molluscicide products for control of schistosomiasis.
Human schistosomiasis, a parasitic and often chronic illness, is one of the major neglected tropical diseases worldwide. It is estimated that 240 million people suffer from schistosomiasis, with more than 200000 fatalities recorded each year. Schistosomiasis is caused by an infection of the blood fl...uke Schistosoma and is transmitted to humans through direct contact with infected water.

FIND and Standard Diagnostics (SD) have developed a lateral flow rapid diagnostic test (RDT) to screen for
T.b. gambiense HAT that is cheap and easy to use. The tests are packed individually and are stable at 40°C for
up to 25 months; they are performed on fresh blood obtained from a finger prick..., and no instrument or electricity is required. The RDT detects host antibodies to infection in populations that are at risk, or in suspect individuals. Positive cases are subjected to further confirmatory methods to identify HAT patients.

Over the past twenty years, huge efforts made by a broad coalition of stakeholders curbed the last epidemic and brought the disease to the brink of elimination. In this paper, the latest figures on disease occurrence, geographical distribution and control activities are presented. Strong evidence in...dicates that the elimination of sleeping sickness ‘as a public health problem’ by 2020 is well within reach. In particular, fewer than one thousand new cases were reported in 2018, and the area where the risk of infection is estimated as moderate, high or very high has shrunk to less than 200,000 km2. More than half of this area is in the Democratic Republic of the Congo. The interruption of transmission of the gambiense form, targeted by the World Health Organization (WHO) for 2030, will require renewed efforts to tackle a range of expected and unexpected challenges. The rhodesiense form of the disease represents a small part of the overall HAT burden. For this form, the problem of under detection is on the rise and, because of an important animal reservoir, the elimination of disease transmission is not envisioned at this stage.

Chagas disease (CD), caused by the parasite Trypanosoma cruzi, affects ~6–7 million people worldwide. Significant limitations still exist in our understanding of CD. Harnessing individual participant data (IPD) from studies could support more in-depth analyses to address the many outstanding resea...rch questions. This systematic review aims to describe the characteristics and treatment practices of clinical studies in CD and assess the breadth and availability of research data for the potential establishment of a data-sharing platform.

Chagas disease (CD) is caused by the parasite Trypanosoma cruzi, and it is endemic in Central, South America, Mexico and the
South of the United States. It is an important cause of early mortality and morbidity, and it is associated with poverty and stigma. A third of
the cases evolve into chronic... cardiomyopathy and gastrointestinal disease. The infection is transmitted vertically and by blood/organ
donation and can reactivate with immunosuppression. Case identification requires awareness and screening programmes targeting the
population at risk (women in reproductive age, donors, immunocompromised patients). Treatment with benznidazole or nifurtimox is most
effective in the acute phase and prevents progression to chronic phase when given to children. Treating women antenatally reduces but does
not eliminate vertical transmission. Treatment is poorly tolerated, contraindicated during pregnancy, and has little effect modifying the
disease in the chronic phase. Screening is easily performed with serology. Migration has brought the disease outside of the endemic
countries, where the transmission continues vertically and via blood and tissue/organ donations. There are more than 32 million migrants
from Latin America living in non-endemic countries. However, the infection is massively underdiagnosed in this setting due to the lack of
awareness by patients, health authorities and professionals. Blood and tissue donation screening policies have significantly reduced
transmission in endemic countries but are not universally established in the non-endemic setting. Antenatal screening is not commonly
done. Other challenges include difficulties accessing and retaining patients in the healthcare system and lack of specific funding for the
interventions. Any strategy must be accompanied by education and awareness campaigns directed to patients, professionals and policy
makers. The involvement of patients and their communities is central and key for success and must be sought early and actively. This review
proposes strategies to address challenges faced by non-endemic countries

Un évènement de santé publique grave (PHE) consiste en une flambée quelconque ou en toute
autre situation en évolution rapide qui peut avoir un impact négatif sur la santé humaine et exiger
une évaluation et des actions immédiates. Le terme prend en compte tout évènement n’ayant pas
...encore entraîné la maladie chez l’homme mais susceptible de la causer à travers une exposition à
des environnements, des produits manufacturés, des animaux, de l’eau ou de la nourriture infectés
ou contaminés. Le Règlement sanitaire international (2005) entend par «risque pour la santé
publique», «la probabilité d’un événement qui peut nuire à la santé des populations humaines,
plus particulièrement d’un événement pouvant se propager au niveau international ou présenter
un danger grave et direct.»

Le présent manuel a pour but de fournir des orientations concernant la conception,
l’organisation et l’évaluation d’un cours visant à établir et à renforcer les capacités des
personnels de santé pour qu’ils puissent prendre en charge les patients ophtalmiques dans
les établissemen...ts de soins de santé primaires dans la Région africaine. Le cours s’inscrit dans
le cadre du perfectionnement professionnel continu au sens le plus large du terme. Son
contenu met l’accent sur des pratiques simples fondées sur des données factuelles que l’on
peut facilement appliquer dans des établissements de soins de santé primaires partout en
Afrique.

La Stratégie de riposte face à la résistance aux antipaludiques en Afrique est un document technique de sensibilisation qui se fonde sur les bases factuelles les plus solides dont on dispose et vise à réduire au maximum la menace et l’impact de la résistance aux antipaludiques de Plasmodium ...falciparum en Afrique. Elle a pour objectifs i) d’améliorer la détection de la résistance et d’assurer une riposte en temps utile ; ii) de retarder l’émergence de la résistance à l’artémisinine et aux médicaments associés utilisés dans les combinaisons thérapeutiques à base d’artémisinine (CTA) ; et iii) de freiner la sélection et la propagation des parasites résistants là où une pharmacorésistance est confirmée. Si la Stratégie cible l’Afrique, il convient de noter que la
menace de la résistance aux antipaludiques concerne tous les pays d’endémie palustre et que les interventions proposées dans le présent document sont applicables dans d’autres régions géographiques à condition d’être adaptées aux spécificités locales.

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.

The WHO continuously reviews available data on SARS-CoV-2 variants of concern. For this version, the global epidemiological
situation of the COVID-19 pandemic as of 21 January 2022 – at a time when the Omicron VOC had been identified in 171
countries across all six WHO Regions and was rapidly re...placing Delta worldwide – was considered Omicron has a substantial growth advantage, higher secondary attack rates and a higher observed reproduction number than Delta.
There is now significant evidence that immune evasion contributes to the rapid spread of Omicron. Other factors may be a shorter
serial interval (by about 0.8 to 1.2 days compared to Delta) and potential increased intrinsic transmission fitness . There is
growing evidence that with Omicron, there is lower vaccine effectiveness (VE) against infection and symptomatic disease soon after vaccination compared to Delta. There is also evidence of accelerated waning of VE over time of the primary series against infection and symptomatic disease for the studied vaccines. Further studies are required to better understand the drivers of transmission and declining incidence in various settings. These factors include the intrinsic transmission fitness properties of the virus, degree of immune evasion, vaccination coverage and level of vaccine-derived and post-infection immunity, levels of social mixing and degree of application of public health and social measures (PHSM).

L'anthrax est une maladie bactérienne, causée par Bacillus anthracis, qui peut se transmettre des animaux
herbivores à l'homme par contact étroit, en mangeant de la viande d'animaux infectés, ou par contamination
environnementale. L'anthrax peut être une maladie grave nécessitant un diagnos...tic et un traitement précoces
pour éviter une issue fatale, un handicap ou une charge financière pour les patients et leurs familles. e. La
maladie affecte également le bien-être de l'homme lorsque le bétail constitue son moyen de subsistance et
un élément important de la pratique agricole. La prévention est un mayen efficace de lutte contre la maladie.
Ces observations fournissent des données sur la survenue des cas d’anthrax dans les communes de Alafia
et Douekiré dans la région de Tombouctou ; les caractéristiques des populations et la description de la zone
en appliquant une approche One Health et la vaccination du cheptel. L’objectif était de Vacciner au moins
80% du cheptel identifié des communes de Alafia dans le cercle de Tombouctou, et de Douekiré dans le
cercle Goundam contre le charbon bactéridien afin de prévenir une épizootie de pathologie infectieuse

Avec l’essor des traitements antirétroviraux (TAR) à base de dolutégravir (DTG) pour soigner les personnes vivant avec
le VIH dans le monde, il est important d’estimer la vitesse à laquelle la résistance acquise au DTG apparaît dans les
populations sous TAR. Bien que la résistance au DT...G ne soit pas apparue dans les populations naïves aux TAR incapables
de supprimer la charge virale dans les essais cliniques, certains éléments portent à croire que la résistance au
DTG peut émerger chez les personnes suivant des schémas thérapeutiques incluant le DTG. L’OMS recommande aux
pays qui étendent les TAR incluant le DTG d’accompagner ce déploiement d’une surveillance en routine de la pharmacorésistance
