...
ica, en la que los macrófagos, los neutrófilos y las células dendríticas frenan el avance del virus y pueden incluso evitar que este provoque síntomas. A esta respuesta no específica le sigue una respuesta adaptativa en la que el organismo genera anticuerpos que se unen específicamente al virus. Estos anticuerpos son las proteínas denominadas inmunoglobulinas. El organismo también genera linfocitos T que reconocen y eliminan las células infectadas por el virus: es lo que se conoce como inmunidad celular. Esta respuesta adaptativa combinada puede eliminar el virus del organismo y, si la respuesta es suficientemente intensa, puede evitar el agravamiento de la enfermedad o la reinfección por el mismo virus. Este proceso se mide a menudo a través de la presencia de anticuerpos en la sangre.

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.

ет от 1 до 2 недель. При вирусной инфекции врожденный иммунитет обеспечивает немедленную реакцию организма, которая заключается в активации неспецифического иммунного ответа, приводящего к замедлению инфекционного процесса макрофагами, нейтрофилами и дендритными клетками, и которая в ряде случаев обусловливает бессимптомное течение инфекции. Затем происходит активация адаптивного иммунного ответа, при котором в организме начинается выработка специфических антител, способных к связыванию с вирусными частицами. Данные антитела являются белками и носят название иммуноглобулинов. Кроме того, в организме образуются Т-клетки, способные распознавать и уничтожать другие клетки, пораженные вирусом. Это звено иммунитета носит название клеточного. Функционирование нескольких звеньев иммунитета при адаптивном ответе может способствовать элиминации вируса из организма, а при достаточной активности реакции – препятствовать переходу заболевания в тяжелую форму и повторному заражению той же инфекцией. Количественной мерой данного процесса является уровень антител в крови.

Coronavirus disease 2019 is also known as COVID-19. It is a viral illness that infects the lungs. It is caused by a virus called SARS-associated coronavirus (SARS-CoV-2). This illness was first seen in late 2019 in China and has spread across the world.
The signs of COVID-19 are like the flu, and y

ou may have a cough, fever, and it may be hard to breathe. It spreads easily through droplets with the virus when you sneeze or cough. The germs also survive on surfaces like tables, door handles, and telephones. That means you can become sick if you touch a surface with the virus and then touch your face.
Some people have a mild case of COVID-19 and are able to stay at home until they feel better. Others may need to be in the hospital if they are very sick. People with COVID-19 most often have to isolate themselves for about 2 weeks.

This document provides guidance for African Union Member States on actions to be taken to ensure they continue to meet all the health

In response to the first cases of coronavirus disease 2019 (COVID-19) reported on the continent, many African Union Member States implemented large-scale public health and social measures (PHSM) rapidly. These measures were aimed at reducing transmission and the number of new cases being reported, p
