IMMUNITE AFRICAINE CONTRE LE COVID-19 : CINQ HYPOTHESES A CONFIRMER

Abstract

January 07, 2020, a new virus responsible for multiple respiratory diseases, called since "SARS-CoV-2" or more commonly "COVID-19". If the first outbreak of the new virus is detected in the city of Wuhan, Hubei Province, towards the end of December 2019, the development and speed of transport has helped the spread of the new virus in five continents. Since then, we have been facing a pandemic, according to the WHO declaration of March 12, 2020. This pandemic has grown steadily, with numbers that are frightening; more than 4 million people infected with the virus (COVID-19) and more than 276 000 deaths on May 9, 2020. The fact remains that the African continent is; more or less, spared from the slaughter, by comparing the number of confirmed cases of coronavirus (COVID-19) contamination or those of deaths in Africa with other continents. Through this work, we will identify the causes which can so far spare the African countries from the American scenario or that of southern Europe, in spite of the poverty and the lack of means which characterize the majority of the countries of the black continent. We arrived at several results, thus among the components of the immunity of the African continent: the late arrival of the pandemic on the continent, a destination less popular with mass tourism, a continent with a low population density, fairly young and has innate immunity.
