Transient disappearance of CD19+/CD5+ B-Lymphocytes in peripheral blood in a patient with CLL during SARS-CoV-2 related mild disease

We report a 64-years old man with B-cell CLL infected by SARS-CoV-2 during his hospitalization for a spondylodiscitis. Because of his health conditions the duration of the antiviral therapy was restricted to one week where we observed a transient disappearance of CD19+/CD5+ B-lymphocytes in peripheral blood.
