El desarrollo de inmunidad a un patógeno por infección natural es un proceso de varias etapas que suele producirse a lo largo de una o dos semanas. El organismo responde a una infección vírica de forma inmediata a través de una respuesta innata no específ...ica, en la que los macrófagos, los neutrófilos y las células dendríticas frenan el avance del virus y pueden incluso evitar que este provoque síntomas. A esta respuesta no específica le sigue una respuesta adaptativa en la que el organismo genera anticuerpos que se unen específicamente al virus. Estos anticuerpos son las proteínas denominadas inmunoglobulinas. El organismo también genera linfocitos T que reconocen y eliminan las células infectadas por el virus: es lo que se conoce como inmunidad celular. Esta respuesta adaptativa combinada puede eliminar el virus del organismo y, si la respuesta es suficientemente intensa, puede evitar el agravamiento de la enfermedad o la reinfección por el mismo virus. Este proceso se mide a menudo a través de la presencia de anticuerpos en la sangre.

Wie passen Trauma und Empowerment zusammen? Was ist den Konzepten gemein und welche Entwicklungen machen sie durch? Wie können komplexe Machtverhältnisse auf individüller und struktureller Ebene beruecksichtigt und überwunden werden?
Diese Publikation der Bundesweiten Arbeitsgemeinschaft der Ps...ychosozialen Zentren für Flüchtlinge und Folteropfer (BAfF e. V.) versucht Antworten zu geben und stellt die Begriffe Trauma und Empowerment – im Kontext Flucht – genaür vor. Hierbei werden auch Formen des Aktivismus in den Blick genommen und die notwendige Unterscheidung zwischen Solidarität und Empowerment verdeutlicht.

MEDBOX Issue Brief 26. Cholera is an acute diarrhoeal infection caused by eating or drinking food or water that is contaminated with the
bacterium Vibrio cholerae. Cholera remains a global threat to public health and is an indicator of inequity and lack of
social development. Researchers have esti...mated that every year, there are 1.3 to 4.0 million cases of cholera, and 21
000 to 143 000 deaths worldwide due to the infection.
However, cholera remains a neglected and underreported disease. Many cases are not recorded due to limitations in
surveillance systems and fears of potential impact on trade or tourism.
Today cholera affects 47 countries across the globe. Almost every developing country faces cholera outbreaks or
the threat of cholera. Major ongoing outbreaks are being reported from Afghanistan, Bangladesh, Democratic
Republic of Congo, Ethiopia and Nigeria. Major outbreaks are currently in Syria and Haiti.
Therefore, MEDBOX decided to produce issue briefs on cholera and available resources in Arabic, English and
French.

Le développement d’une immunité face à un agent pathogène à la suite d’une infection naturelle comporte plusieurs étapes et prend généralement une à deux semaines. Une infection virale entraîne immédiatement une réponse immunit...aire innée, non spécifique, au cours de laquelle les macrophages, les neutrophiles et les cellules dendritiques ralentissent la progression du virus et peuvent même éviter l’apparition de symptômes. Cette réponse non spécifique est suivie d’une réponse adaptative, au cours de laquelle l’organisme produit des anticorps qui se lient spécifiquement au virus. Ces anticorps sont des protéines appelées immunoglobulines. L’organisme produit également des lymphocytes T qui reconnaissent et éliminent les cellules infectées par le virus. Cette réponse adaptative permet parfois d’éliminer le virus de l’organisme et, si elle est suffisamment forte, d’éviter l’aggravation de la maladie ou la réinfection par le même virus. Ce processus est souvent mesuré par la présence d’anticorps dans le sang.

An update from the EU Early Warning System
Rehabilitation in health systems provides recommendations for Member States and other relevant stakeholders to strengthen and expand the availability of quality rehabilitation services. Currently, there is a significant unmet need for rehabilitation services and it is frequently undervalued in the h...ealth system. As populations age and the prevalence of noncommunicable diseases and injuries increases, and the demand for rehabilitation grows, strengthening rehabilitation in health systems becomes ever more paramount.

La Polychimiothérapie (PCT) guérit la lèpre, interrompt la transmission et prévient les infirmités. La PCT est disponible gratuitement dans tous les centres de santé.
Unlike foot and mouth disease, the avian flu, e-coli or listeria, the COVID-19 pandemic has not spread directly through livestock or agriculture commodities, and has therefore not directly disrupted on-farm production. However, the crisis is undermining the ability of farms and agri-enterprises to e...nsure consistent supplies of food to markets due to enforced closures, labour shortages resulting from illness, and slowdowns in operations caused by physical distancing and lockdowns.

his guidance details basic decontamination principles and procedures that should be followed to decontaminate the physical environment in the context of the coronavirus disease 2019 (COVID-19) pandemic. Surface contamination and transmission risk all differ by the type of setting and the volume of p...eople that frequent each setting (e.g. healthcare facilities, public transport, and other busy facilities/workplaces), even though the principles of environmental decontamination remain the same.
