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.

People affected by impairments and disabilities associated with TB are even more likely to belong to marginalized segments of society and are more likely to have their human rights unprotected. The challenges faced by people affected by TB include the consequences of impairment and disability associ...ated with the disease, its treatment as well as with the stigma and discrimination applied to people affected by TB. There is now compelling evidence that the disease and its treatment affect quality of life and life expectancy even after successful treatment.
The WHO Global Tuberculosis Programme has produced the first policy brief on TB-associated disability, building on the increasing evidence in recent years on the unaddressed needs of people with TB who experience impairment and disability while on TB treatment and after completing TB treatment.

AMR is one of the Key priority of the global health security agenda action package, as well as it is one of the commitments of Ministry of Public Health Afghanistan to combat AMR. In Afghanistan because of war and some other political issues the borders of the country are not well secured and well c...ontrolled therefore control of smuggling of medicine is a big challenge in front of the rational use of medicine.

Systematic screening for TB disease is the systematic identification of people at risk for TB disease, in a predetermined target group, by assessing symptoms and using tests, examinations or other procedures that can be applied rapidly.
Systematic screening can benefit people who are at risk of get...ting TB, as early detection and start of treatment can improve their outcomes and reduce their costs. It can also benefit entire communities at higher risk for TB, by reducing the prevalence of TB disease and preventing future cases.

This second edition of the Basic Malaria Microscopy package is a stand-alone product,
providing all that is needed to conduct a complete training course
This guide focuses on three main areas: how to support a person whose condition warrants home care because of non-severe symptoms and home care is recommended by local jurisdictions; how to prevent the spread of COVID-19 in the home; and how to provide emotional support to family members. While this... manual provides information on danger signs of COVID-19, it should not be used as a guide for when and how a person who has COVID-19 (or its symptoms) should seek medical care. All content adapted to different countries should reflect local policy guidelines and recommendations.
