Principaux faits
D’après les estimations, 6 à 7 millions de personnes dans le monde sont infectées par Trypanosoma cruzi (T. Cruzi), le parasite responsable de la maladie de Chagas. La plupart de ces personnes vivent en Amérique latine.
La transmission à l’être humain se fait principalem...ent, en Amérique latine, par l’intermédiaire d’un insecte appelé triatome, qui peut être porteur de T. cruzi.
Parmi les autres modes de transmission de la maladie de Chagas, figurent : la transmission orale (par voie alimentaire), la transfusion de sang ou de produits sanguins, la transmission mère-enfant (congénitale), la transplantation d’organes et les accidents de laboratoire.
La maladie de Chagas ne touchait auparavant que des zones rurales de la Région des Amériques, et surtout de l’Amérique latine. Ces dernières décennies, toutefois, les mouvements de population ont fait que la plupart des personnes infectées sont des habitants de zones urbaines (urbanisation) et que la maladie s’est propagée à d’autres continents (où T. cruzi se transmet par des voies non vectorielles).
L’infection à T. cruzi est curable si un traitement est instauré rapidement après l’infection.
Chez les personnes infectées de façon chronique, un traitement antiparasitaire peut éventuellement prévenir ou enrayer la progression de la maladie, et éviter sa transmission, notamment de la mère à l’enfant.
Jusqu’à 30 % des personnes infectées de façon chronique présentent des troubles cardiaques, et jusqu’à 10 % d’entre elles souffrent de troubles digestifs et/ou neurologiques, ce qui peut imposer un traitement particulier.
Les principales méthodes de prévention de la maladie de Chagas en Amérique latine sont la lutte antivectorielle ainsi que d’autres stratégies visant à réduire la transmission vectorielle.
Dans le monde entier, le dépistage sanguin joue un rôle crucial dans la prévention de l’infection par transfusion ou transplantation d’organes.
Il est essentiel de détecter et de traiter l’infection chez les femmes et les filles en âge de procréer, ainsi que de soumettre tout nouveau-né et ses frères et sœurs à un dépistage dans le cas où la mère est infectée et n’a jamais reçu de traitement antiparasitaire.
Certains facteurs socio-économiques et environnementaux influent fortement sur la maladie de Chagas, dont la propagation et les différentes dimensions interdépendantes justifient la nécessité de mettre en œuvre des stratégies de lutte multisectorielles.
Quelques pays ont mis en place la notification et la surveillance des cas aigus et chroniques et des voies de transmission actives, qui sont essentielles à la lutte contre la maladie de Chagas.

Since the launch of the Global Programme to Eliminate Lymphatic Filariasis (GPELF) in 2000, more than 910 million people have received preventive chemotherapy for lymphatic filariasis (LF) and many thousands have received care for chronic manifestations of the disease. To achieve this, millions of c...ommunity drug distributors (CDDs), community members and health personnel have worked together each year to ensure that at-risk communities receive preventive chemotherapy through mass drug administration (MDA). The successes of 20 y of partnership with communities is celebrated, including the application of community-directed treatment, the use of CDDs and integration with other platforms to improve community access to healthcare. Important challenges facing the GPELF moving forward towards 2030 relate to global demographic, financing and programmatic changes. New innovations in research and practice present opportunities to encourage further community partnership to achieve the elimination of LF as a public health problem. We stress the critical need for community ownership in the current Covid-19 pandemic, to counter concerns in relaunching MDA programmes for LF.

Chagas disease is currently endemic and also predicted to be at increased transmission risk under future climate change scenarios. Similarly, an expansion of areas in the United States at increased risk for Chagas disease transmission is also expected over the next several decades under climate chan...ge scenarios. Of particular interest is the predicted northern shift of triatomine species to central regions of the United States with historically unsuitable climates for T. cruzi vectors. The weight of evidence regarding the influences climate change may pose on T. cruzi vector species distributions demonstrates the sensitivity of Chagas disease transmission to future climate variability. In order to advance forecasts for the impact climate change may have on Chagas disease transmission in the Americas, it is imperative to
further develop, utilize, and perhaps combine predictive species distribution modeling approaches that integrate accurate, long term data on climate variables, vector species distributions, Chagas disease incidence, as well as other socio-ecological variables.

This facilitator’s manual is designed to support the implementation of the Dengue Clinical Management training course. The guide contains specific instructions for the facilitator and provides:
- a detailed description of the clinical course of dengue illness, which reflects the dynamic and sys...temic nature of dengue that has crucial bearing on the patient’s management;
- a detailed description of the basic pathophysiological changes of severe dengue (i.e. plasma leakage and hypovolaemia/shock) and guidance on the recognition of these changes and appropriate action of management;
- a brief discussion on WHO classification (1997) and its limitations;
- guidance on the differential diagnoses that can be confused with dengue or vice versa; they were described according to the stage of disease;
- a more focused guide on the disease monitoring in accordance with the dynamic changes as the disease progresses;
- emphasis on the importance of monitoring the plasma leakage (haemodynamic status of the patient, clinical signs of plasma leakage and haematocrit);
- a clearer algorithm for fluid management in cases of severe dengue; and
- emphasis on the importance of recognizing or suspecting significant occult bleed. Keep the facilitator’s manual with you each day as you prepare and deliver the information. Use it as a reference when delivering classroom presentations, but avoid reading directly from it during sessions.

Chagas disease is a neglected tropical disease caused by the protozoan parasite Trypanosoma cruzi. It is a significant public health problem, affecting millions of people worldwide. And although it was described 110 years ago, only two old nitroheterocyclic drugs, benznidazole and nifurtimox, are cu...rrently available for the treatment of Chagas disease and both have several limitations. Besides the clear unmet medical need, many challenges preclude the development of new treatments, some of them related to a lack of understanding of the pathophysiology of the disease and parasite-host interactions. New knowledge and tools are becoming available, but the number of new chemical entities progressing through the preclinical pipeline is inadequate. Therefore, it is still uncertain whether safe, effective and accessible new drugs will be available in the near future. The Chagas disease research community must commit to even greater collaboration to ensure that patients eventually benefit from better treatments.

Background: Despite several cycles of Mass Drug Administration (MDA), however, the prevalence of Soil-transmitted helminthiasis (STH) remains high in Bangladesh. A clear understanding of local knowledge, attitudes, and practices (KAP) related to the acc...pan>eptance and utilization of MDA is critical for effective implementation of this intervention.
Methods: This research, a cross-sectional descriptive study that utilized quantitative methods, was conducted between February and June 2017. A total of 380 questionnaire surveys were distributed to school-aged children (SAC), the parents of SAC, and school teachers.
Results: Out of 160 SACs, 81.9% knew of STH and 75.6% knew of MDA. SAC showed a high awareness of STH and recognized the importance of preventive measures and MDA. In terms of the parents of SAC and school teachers, close to half of the respondents were knowledgeable about STH and MDA. While nearly all of the participants held positive attitudes toward MDA, the respondents pointed out that school-based MDA presents severe limitations, as non-school-going children are neglected by this effort. A total of 68.3% of all school teachers and 56.8% of all parents of SAC found MDA efforts to be effective.
Conclusion: STH infections still remain a significant public health burden in Bangladesh. Reforming the MDA policy is necessary to achieve the target of STH elimination.

Malgré les progrès récents vers la mise au point d’un traitement hautement efficace et abordable contre le virus de l’hépatite C, beaucoup de personnes infectées par ce virus ne connaissent pas leur statut. L’Organisation mondiale de la Santé (OMS) estime qu’en 2019, 58 millions ...de personnes à travers le monde étaient atteintes d’une infection chronique par le virus de l’hépatite C, et qu’à peine 21 % d’entre elles avaient été diagnostiquées. Le défaut de sensibilisation, l’accès limité aux services de dépistage et de traitement, la stigmatisation, la discrimination et d’autres obstacles structurels contribuent au faible taux d’utilisation des services de dépistage du virus de l’hépatite C.

Previous studies on LGBTI older people offer valuable information on the lived experiences of these communities and demonstrate that they face unique challenges with aging, emphasizing the difficulties related to access to care. Very few studies on older people and aging include a focus on sexual orientation or gender identity; however, it is possible to point out that HIV/AIDS is one of the most significant health disparities confronting LGBTI older persons, followed by physical and mental health problems, substance use, social isolation, poverty, and the lack of access to quality healthcare, including long-term care facilities or other institutions. Closing the gap in access and quality of health and care services is an imperative to increase longevity, health status and quality of life of LGBTI older people.

As a high-burden neglected tropical disease, soil-transmitted helminth (STH) infections remain a major problem in the world, especially among children under five years of age. Since young children are at high risk of being infected, STH infection can have a long-term negative impact on their life, i...ncluding impaired growth and development. Stunting, a form of malnutrition in young children, has been long assumed as one of the risk factors in acquiring the STH infections. However, the studies on STH infection in children under five with stunting have been lacking, resulting in poor identification of the risk. Accordingly, we collected and reviewed existing related research articles to provide an overview of STH infection in a susceptible population of stunted children under five years of age in terms of prevalence and risk factors. There were 17 studies included in this review related to infection with Ascaris lumbricoides, Trichuris trichiura, hookworm, and Strongyloides stercoralis from various countries. The prevalence of STH infection in stunted children ranged from 12.5% to 56.5%. Increased inflammatory markers and intestinal microbiota dysbiosis might have increased the intensity of STH infection in stunted children that caused impairment in the immune system. While the age from 2 to 5 years along with poor hygiene and sanitation has shown to be the most common risk factors of STH infections in stunted children; currently there are no studies that show direct results of stunting as a risk factor for STH infection. While stunting itself may affect the pathogenesis of STH infection, further research on stunting as a risk factor for STH infection is encouraged.
