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 has been developed for the WHO Regional Office for the Eastern Mediterranean to establish a regional plan of action to support the countries of the Region to rapidly accelerate the scaling up of their capacities for the prevention and early detection of, and ... rapid response to, coronavirus disease 2019 (COVID-19), as required under the International Health Regulations (IHR 2005). The regional plan is aligned with the WHO global 2019 novel coronavirus strategic preparedness and response plan, but tailored to the regional context.

Infectious diseases, such as COVID-19, can have a significant impact on children’s and their caregivers’
wellbeing beyond the disease itself. In terms of child protection, there are three main potential
secondary impacts:
- Neglect and lack of parental care.
- Mental health and Psychosocia...l distress.
- Increased exposure to violence, including sexual violence, physical and emotional abuse.

Policy brief, 24 July 2020
The COVID-19 pandemic has affected older people disproportionately, especially those living in long-term care facilities. In many countries, evidence shows that more than 40% of COVID-19 related deaths have been linked to long-term care facilities, with figures being as h...igh as 80% in some high-income countries. Concerted action is needed to mitigate the impact across all aspects of long-term care, including home- and community-based care, given that most users and providers of care are those who are vulnerable to severe COVID-19.
This policy brief provides 11 policy objectives and key action points to prevent and manage COVID-19 across long-term care. Its intended audience is policy makers and authorities (national, subnational and local) involved in the COVID-19 pandemic. The brief builds on currently available evidence on the measures taken to prevent, prepare for and respond to the COVID‑19 pandemic across long-term care services including care providers

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.

Food and nutrition security in the Democratic Republic of the Congo is subject to the relentless impact of conflict, epidemics and climate events that have persisted in the country for decades, further compounded by the global COVID-19 pandemic. Lack of infrastructure and investment in agriculture, ...health and human capital development combine to impede progress towards the achievement of Sustainable Development Goals 2 and 17. While there are several legal instruments and policies that promote food and nutrition security, poor coordination, weak national capacity and exponential population growth present serious obstacles to the achievement of zero hunger. Political instability and siloed sectoral responses to humanitarian and development needs have also affected results to date.

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. The ATA-C is intended to be implemented by an experienced team, in collaboration with relevant ministries and users’ organizations.

Objective: To review the effectiveness of antibiotic stewardship interventions in hospitals in low- and middle-income countries.

Nat Commun 9, 5370 (2018). https://doi.org/10.1038/s41467-018-07804-8. Mycobacterium ulcerans is the causative agent of Buruli ulcer, a neglected tropical skin disease that is most commonly found in children from West and Central Africa. Despite the severity of the infection, therapeutic options are... limited to antibiotics with severe side effects. Here, we show that M. ulcerans is susceptible to the anti-tubercular drug Q203 and related compounds targeting the respiratory cytochrome bc1:aa3. While the cytochrome bc1:aa3 is the primary terminal oxidase in Mycobacterium tuberculosis, the presence of an alternate bd-type terminal oxidase limits the bactericidal and sterilizing potency of Q203 against this bacterium. M. ulcerans strains found in Buruli ulcer patients from Africa and Australia lost all alternate terminal electron acceptors and rely exclusively on the cytochrome bc1:aa3 to respire. As a result, Q203 is bactericidal at low dose against M. ulcerans replicating in vitro and in mice, making the drug a promising candidate for Buruli ulcer treatment.

2014-2020, Draft March 2014
The epidemiology of wheeze in children, when assessed by questionnaires, is dependent on parents' understanding of the term “wheeze”.
In a questionnaire survey of a random population sample of 4,236 children aged 6–10 yrs, parents' definition of wheeze was assessed. Predictors of a correct ...definition were determined and the potential impact of incorrect answers on prevalence estimates from the survey was assessed.
Current wheeze was reported by 13.2% of children. Overall, 83.5% of parents correctly identified “whistling or squeaking” as the definition of wheeze; the proportion was higher for parents reporting wheezy children (90.4%). Frequent attacks of reported wheeze (adjusted odds ratio (OR) 3.0), maternal history of asthma (OR 1.5) and maternal education (OR 1.5) were significantly associated with a correct answer, while the converse was found for South Asian ethnicity (OR 0.6), first language not English (OR 0.6) and living in a deprived neighbourhood (OR 0.6).
In summary, the present study showed that misunderstanding could lead to an important bias in assessing the prevalence of wheeze, resulting in an underestimation in children from South Asian and deprived family backgrounds. Prevalence estimates for the most severe categories of wheeze might be less affected by this bias and questionnaire surveys on wheeze should incorporate measures of parents' understanding of the term wheeze.
