Outcomes
Primary Outcome Measures
Comparison of the percentage of T cells expressing the HLA-G receptor ILT2 (CD3+CD4+ILT2+ T cells, and CD3+CD8+ILT2+ T cells) between the 3 groups of patients.
The CD3 + T lymphocyte cell populations (CD4 + ILT2 + and CD8 + ILT2 +) will be compared between the groups of patients
Comparison of the expression of circulating soluble HLA-G, between the groups of patients.
Blood levels of soluble HLA-G and plasma microvesicles with expression of HLA-G will be compared between the groups of patients.
Secondary Outcome Measures
1 month survival
Vital status collected 1 month post inclusion for all the patients
Assessment of the severity of the disease according to the isoform of HLA-G
Comparison of the isoforms (alleles) of HLA-G regarding the severity of the disease for the infected patients.
Comparison of the expression of one of the cell receptors of the SARS-CoV-2 virus, called BSG (Basigin), whose expression is modified by the interaction between HLA-G.
The expression of the BSG cell receptor induced by HLA-G will be compared between COVID19 patients and uninfected patients.

5. Study Description
Brief Summary
The aim of the research is to study the immune checkpoint linked to the HLA-G molecule in the dysregulation of the control of COVID-19 infection.
Detailed Description
Single-center, prospective, open-ended, interventional study with minimal risks and constraints. Patients will be divided into 3 groups: patients not infected with COVID-19, patients infected with COVID-19 not hospitalized, patients infected with COVID-19 hospitalized.
