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.

he central Sahel region—Burkina Faso, Mali and Niger—is facing a severe humanitarian and protection crisis.
Massive displacement, most of it driven by intense and largely indiscriminate violence perpetrated by a range of armed actors against civilian populations, is taking place across the regi...on. While internal displacement is on the rise substantial numbers of refugees have fled to neighboring countries, and the situation risks spilling over into the coastal countries of Benin, Côte d'Ivoire, Ghana, and Togo.
This context is exacerbated by the COVID-19 pandemic, which is already affecting areas hosting refugees and IDPs

As our world changes, so too does the burden of disease. Globalisation, evolving trade and consumption patterns, and increased access to life-saving medical care are just some of the factors that have transformed the global health landscape.
A global hunger crisis -- fuelled by conflict, economic turbulence and climate-related shocks -- has been exacerbated by the COVID-19 pandemic. The number of people experiencing food insecurity and hunger has risen since the onset of the pandemic. The IRC estimates that the economic downturn alone w...ill drive the number of hungry people up by an additional 35 million in 2021. Without drastic action, the economic downturn caused by COVID-19 will suspend global progress towards ending hunger by at least five years.

The menu was developed using the WHO-CHOICE methodology to prepare and update, as appropriate, WHO estimates of the cost-effectiveness of a range of mental health interventions, in line with the development of Appendix 3 to the global action plan for the prevention and control of noncommunicable dis...eases 2013–2020.
WHO-CHOICE is a programme that helps countries to identify priorities based on health impact and cost-effectiveness. It can be applied to a wide range of strategies relevant to policies affecting health outcomes. All options are compared to a common comparator, a null scenario in which the impacts of currently implemented interventions are removed, thereby enabling comparison of interventions across geographical areas and aspects of health.

The assistive technology capacity assessment (ATA-C) is a system-level tool to evaluate a country’s capacity to finance, regulate, procure and provide assistive technology. It can be used for awareness raising, policy and programme design, and ongoing monitoring and evaluation. This manual provide...s guidance and practical information on the ATA-C implementation process.

By almost any measure, human health is better now than at any time in history. Life expectancy has soared from 47 years in 1950–1955, to 69 years in 2005–2010, and death rates in children younger than 5 years of age have decreased substantially, from 214 per thousand live births in 1950–1955, ...to 59 in 2005–2010. But these gains in human health have come at a high price: the degradation of nature’s ecological systems on a scale never seen in human history. A growing body of evidence shows that the health of humanity is intrinsically linked to the health of the environment, but by its actions humanity now threatens to destabilise the Earth’s key life-support systems.
As a Commission, we conclude that the continuing degradation of natural systems threatens to reverse the health gains seen over the last century. In short, we have mortgaged the health of future generations to realise economic and development gains in the present.
Despite present limitations, the Sustainable Development Goals provide a great opportunity to integrate health and sustainability through the judicious selection of relevant indicators relevant to human wellbeing, the enabling infrastructure for development, and the supporting natural systems, together with the need for strong governance.

In Central and West Africa, regions together comprising 27 countries and 605 million people, the average person is exposed to particulate pollution levels that are more than 4 times the World Health Organization’s (WHO) guideline of 5 μg/m³1. If these particulate pollution levels persist, averag...e life expectancy in the regions would be 1.6 years lower, and a total of 971 million person-years would be lost, relative to if air quality met the WHO guideline. The Democratic Republic of the Congo, Rwanda and Burundi, are the top three most polluted countries in the region.
