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 ...ribute-to-highlight medbox">réponse immunitaire 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.

In the context of health, stigma is the negative association between a person or group of people who share certain characteristics and a specific disease. In an outbreak, this may mean people are labeled, stereotyped, discriminated against, treated ...separately, and/or experience loss of status because of a perceived link with a disease.

Neither a Turning Point Nor an Overall Determinant
Nine years into the (civil) war, Syria is in an extraordinarily poor position to confront the Covid-19 pandemic. Instead of the pandemic leading towards the uniting of local, regional, and international actors involved in Syria around a common purp...ose, con-flict dynamics have hampered an effective response to Covid-19. Yet, the pandemic is unlikely to become a decisive turning point in conflict dynamics or an overall deter-minant of its future trajectory.

Women in Myanmar have traditionally been underrepresented in public decision-making processes, a trend which is continuing in structures established to respond to COVID-19. This means that even as women are disproportionately affected by the crisis, they have less say in how t...heir communities and country respond to it, increasing the risk of a COVID-19 response that does not adequately address the needs and priorities of the most vulnerable women and girls.

UNAIDS report on the global AIDS epidemic shows that 2020 targets will not be met because of deeply unequal success; COVID-19 risks blowing HIV progress way off course. Missed targets have resulted in 3.5 million more HIV infections and 820 000 more AIDS-related deaths since 2015 than if the world w...as on track to meet the 2020 targets. In addition, the response could be set back further, by 10 years or more, if the COVID-19 pandemic results in severe disruptions to HIV services.

The evidence produced in mathematical models plays a key role in shaping policy decisions in pandemics. A key question is therefore how well pandemic models relate to their implementation contexts. Drawing on the cases of Ebola and in...fluenza, we map how sociological and anthropological research contributes in the modelling of pandemics to consider lessons for COVID-19. We show how models detach from their implementation contexts through their connections with global narratives of pandemic response, and how sociological and anthropological research can help to locate models differently. This potentiates multiple models of pandemic response attuned to their emerging situations in an iterative and adaptive science. We propose a more open approach to the modelling of pandemics which envisages the model as an intervention of deliberation in situations of evolving uncertainty. This challenges the ‘business-as-usual’ of evidence-based approaches in global health by accentuating all science, within and beyond pandemics, as ‘emergent’ and ‘adaptive’.

The report finds that, as of 3 November, in 87 countries with age-disaggregated data, children and adolescents under 20 years of age accounted for 1 in 9 of COVID-19 infections, or 11 per cent of the 25.7 million infections reported by these countries. More reliable, age-disaggregated data on infect...ion, deaths and testing is needed to better understand how the crisis impacts the most vulnerable children and guide the response

The health impact of radiological and nuclear emergencies can last for decades. Lessons learned from past radiological and nuclear accidents have demonstrated that the mental health and psychosocial consequences can outweigh the direct physical health impacts of radiation exposure. International rad...iation emergency preparedness and response standards outline provisions for mitigating these effects. Yet, practical guidance for addressing the mental health and psychosocial aspects of radiation emergencies remains scarce.
This framework aims to promote integration between the MHPSS and radiation protection fields. It is intended for officials and specialists involved in radiation emergency planning and risk management as well as MHPSS experts working in health emergencies.

Concentrations of the major greenhouse gases, CO2 , CH4 , and N2 O, continued to increase despite the temporary reduction in emissions in 2020 related to measures taken in response to COVID-19.
2020 was one of the three warmest years on record. T...he past six years, including 2020, have been the six warmest years on record. Temperatures reached 38.0 °C at Verkhoyansk, Russian Federation on 20 June, the highest recorded temperature anywhere north of the Arctic Circle.
The trend in sea-level rise is accelerating. In addition, ocean heat storage and acidification are increasing, diminishing the ocean’s capacity to moderate climate change.

Rwanda first confirmed cases of coronavirus disease 2019 (COVID-19) in March 2020. Although the number of cases has been low, health system resources are being redirected to respond and an increasing number of children are affected by the socio-economic impacts of the pandemic, including disruptions... to schooling and heightened protection risks.
While Rwanda remained Ebola-free during the outbreak, it remains a priority country and continues to maintain its Ebola preparedness. Rwanda is also home to 147,000 refugees, half of whom are children, who require assistance in and outside of camps.1 In 2021, UNICEF will continue to deliver life-saving services to refugees and children and families affected by COVID-19 and its socio-economic impacts, and maintain its Ebola preparedness and contingency planning.
