*BMT, bone marrow transplant; CKD, chronic kidney disease; HBP, high blood pressure; HT, heart transplant; N2, nucleocapsid; NA, not available; Pt, patient; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2. †The definition of the severity of the patients has been organized according to the following criteria: Mild—general malaise, cough, diarrhea, headache, fever, anosmia, dysgeusia, myalgia, rhinorrhea; moderate—previous symptoms plus dyspnea, mild respiratory failure, or unilateral pneumonia, severe—previous symptoms plus bilateral pneumonia.
