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.

This document is to support local authorities, leaders and policy-makers in cities and other urban settlements in identifying effective approaches and implementing recommended actions that enhance the prevention, preparedness and readiness for COVID...-19 in urban settings, to ensure a robust response and eventual recovery. It covers factors unique to cities and urban settings, considerations in urban preparedness, key areas of focus and preparing for future emergencies.

Breastmilk is the best source of nutrition for infants, including infants whose mothers have confirmed or suspected coronavirus infection. As long as an infected mother takes appropriate precautions—outlined below—she can... breastfeed her baby. Breastmilk contains antibodies and other immunological benefits that can help protect against respiratory diseases. A growing body of evidence supports the importance of breastfeeding for a child’s growth, development, and health, as well as for helping them avoid obesity and noncommunicable diseases later in life.

The number of African Union Member States reporting COVID-
19 cases is increasing and there is a likelihood of community transmission. The WHO recently modified the COVID-19 suspect case definition to include severe acute respiratory infection and advises testing of all severe acute res...piratory illness (SARI) cases.1 However, many Member States have not yet started implementing these changes, they are still focussing surveillance efforts on individuals with travel history to an area with local COVID-19 transmission. This means patients with similar symptoms, but no apparent contact, may not
be investigated.

Centre Africain de contrôle et de prévention des maladies (CDC Afrique) protocole par la surveillance renforcée du syndrome respiratoire aigu sévère (SRAS) et du syndrome grippal pour COVID-19 en Afrique
Mars 2020
Le nombre d’États membres de l’Union signalant des cas de COVID-19 est ...en augmentation et il est probable que la transmission communautaire en Afrique se produira. L’OMS a récemment modifié la définition de cas suspect de COVID-19 pour inclure des infections respiratoires aiguës sévères et conseille de tester tous les cas de syndrome respiratoire aigu sévère (SRAS).1 Cependant, de nombreux États membres n’ont pas encore commencé à mettre en œuvre ces changements, ils concentrent toujours leurs efforts
de surveillance sur les personnes ayant des antécédents de voyage vers une zone de transmission locale de COVID-19. Cela signifie que les patients présentant des symptômes similaires, mais sans aucun contact apparent, peuvent ne pas être enquêtés.

This strategy, produced by IFRC, UNICEF and WHO, provides an overview of RCCE coordination approach and priorities across the different phases of the COVID-19 preparedness and response
Presently, there is no evidence that the virus responsible for the current COVID-19 pandemic is carried by domestic food-producing animals, such as chickens, ducks, other poultry, pigs, cattle, camels, horses, sheep, goats, rabbits, guinea pigs or fish. While live animals can be a source of pathogen...s, all types of food can potentially be contaminated through contact with contaminated equipment, surfaces or environments. Proper cleaning and the prevention of cross-contamination are critical in the control of foodborne illnesses. The application of sound principles of environmental sanitation, personal hygiene and established food safety practices will reduce the likelihood that harmful pathogens will threaten the safety of the food supply, regardless of whether the food is sourced from intensive agriculture, small stakeholders or wildlife.

Only 8,730 asylum applications were registered in the EU+ in April, the lowest since at least 2008, and a massive 87% decrease from pre-COVID-19 levels in January and February.
The European Asylum Support Office (EASO) has released a special report... which shows that the COVID-19 related travel restrictions and national health measures which were imposed during the past few months led to a dramatic cut in asylum applications in Europe.

This brief considers the rationale for shielding individuals at high risk of severe disease or death from COVID-19 in low- and middleincome countries. It provides an overview of proposed approaches to shielding, discusses the categories of individua...ls who may be identified for shielding, and outlines the likely difficulties of these measures and ways to mitigate them.

This note provides information and practical guidance to support gender-based violence (GBV) practitioners to integrate attention to disability into GBV prevention, risk mitigation and response efforts during the COVID-19 pandemic. This document complements other resources relating to GBV and COVID-...19 and assumes that the user is already familiar with common GBV prevention, risk mitigation and response approaches.

Le Covid-19 est une infection transmise par l'air. Cela signifie que le virus est transmis par l'appareil respiratoire de la personne atteinte, en particulier lorsqu'elle tousse ou parle à voix haute.
La pandémie actuelle de COVID-19 entraîne des difficultés exceptionnelles et sans précédent pour les autorités compétentesa responsables des systèmes nationaux decontrôle de la sécurité sanitaire des alimentsb, qui sont tenues de continuer à assurer des fonct...ions et des activités de routine en se conformant aux règlements nationaux et aux recommandations internationales. Dans de nombreux pays, le personnel employé par les autorités compétentes travaille généralement à domicile car le télétravail est devenu la norme et toutes les réunions en présentiel sont annulées ou sont réorganisées sous forme de téléconférence. Il est difficile de maintenir, sans interruption, les activités de routine telles que l’inspection des entreprises du secteur alimentaire, la certification des exportations, le contrôle des denrées alimentaires importées, le suivi et la surveillance de la sécurité de la chaîne d’approvisionnement alimentaire, l’échantillonnage et l’analyse des aliments, la gestion des incidents alimentaires, les conseils sur la sécurité sanitaire des aliments et la réglementation relative aux denrées alimentaires à l’intention de l’industrie et la communication au grand public sur les questions relatives à la sécurité sanitaire des aliments.

According to WHO, infection prevention and control (IPC) is a scientific approach and practical solution designed to prevent harm caused by infection to patients and health workers. It is grounded in infectious diseases, epidemiology, social science... and health system strengthening. IPC occupies a unique position in the field of patient safety and quality universal health coverage since it is relevant to health workers and patients at every single health-care encounter. Poor WASH and IPC lead to health acquired infections, transmission of diseases from health facilities to communities and increased use of antibiotics and exacerbate outbreak and spread of infections- in this case- COVID- 19. On the contrary, effective IPC reduces hospital-acquired infections by at least 30% (WHO 2016).
