Brief Summary

The COVID-19 epidemic has now raged for more than a year with more than 100 million identified cases and nearly 2.5 million deaths worldwide. Since November 2020, we have been witnessing the emergence of viral variants in different regions of the world. This expected genetic drift of the virus, but somewhat abrupt since November, raises questions concerning the characteristics of transmissibility, pathogenicity, sensitivity to possible treatments, and escape from natural or vaccine immunity. The objective of this study is to find out whether the new variants of SARS-CoV-2 are associated with particular clinical forms. The results of this research will provide elements to determine whether the new variants of SARS-CoV-2 are associated with more severe clinical forms.
