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.

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.

To contain the spread of COVID-19 and to keep infections at a manageable level, many countries have instituted lockdowns and social distancing. In India, a nationwide 21-day lockdown was announced with effect from 25 March 2020. This lockdown is expected to avert a sudden and large in...crease in the number of infections in the short term. Additionally, interventions such as social distancing and isolation of infected individuals over several months could reduce peak infections. Interventions such as frequent handwashing, reduced mass gatherings, contact tracing, and quarantines could slow transmission and reduce overall infections.

This guidance note developed by UNICEF helps WASH staff in their preparedness and response to the current COVID-19 pandemic. It provides an overview of Infection Prevention and Control (IPC) and its intersection with water, sanitation and hygiene (WASH). It also provides key actions that staff can i...mplement to help prevent infection and its spread in health-care facilities: from human to human, among health care workers and patients, through droplets, and by touching surfaces contaminated with the virus. WASH, including waste management and environmental cleaning, is essential for IPC

The following Emergency Response Plan for the COVID-19 pandemic seeks to set out activities that will be undertaken by humanitarian actors in Ukraine over the course of 2020 to respond to the public health impact of the epidemic – as well as the indirect, socio-economic impact on people’s well-b...eing, which will span across many areas. Given the extensive public exposure of the COVID-19 threat, the response will cover the whole of Ukraine, while providing a distinct focus on Donetska and Luhanska oblasts that have been ravaged by an armed conflict for the last six consecutive years. The planned COVID-19 response in the two conflict-affected oblasts will be treated as an annex to the current Humanitarian Response Plan for Ukraine

Countries have shut down the economy to slow the spread of the coronavirus. Supermarket shelves remain stocked for now. But a protracted pandemic crisi s could quickly put a strai n on the f ood supply chains, a complex web of interactions involving farmers, agricultu...ral inputs, processing plants, shipping, retailers and more. The shipping industry is already reporting slowdowns because of port closures, and logistics hurd les could disrupt the supply chains in coming weeks.

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 restr...ictions and national health measures which were imposed during the past few months led to a dramatic cut in asylum applications in Europe.

COVID-19 has turned the world upside down. Everything has been impacted. How we live and interact with each other, how we work and communicate, how we move around and travel. Every aspect of our lives has been affected.
Annex to Considerations in adjusting public health and social measures in the context of COVID-19
In response to COVID-19, countries around the globe have implemented several public health and social measures (PHSM), including large scale measures such as movement restrictions, closure of schools and businesses, geographical area quarantine, and international travel restrictions.
The spread of COVID-19 poses a challenge for emerging markets such as those in Africa and Latin America. While governments around the world are suffering from a shortage of ventilators, hospital beds, and personal protective equipment, availability of these items is already extremely limited in some... countries. In Africa, countries including Mali, Liberia, and Burkina Faso have only a few ventilators available to aid their populations, and there is also a lack of reliable oxygen supplies, ICUs, and healthcare workers to treat the sick. Additionally, many countries in Africa are already suffering from food insecurity and weak economies, which will worsen the long-term effects of coronavirus.
Keeping these factors in mind, GeoPoll conducted a remote study in 12 countries in sub-Saharan Africa on the effects coronavirus is already having on people throughout the region.
