Plasma donor demographic and COVID-19 disease characteristics. n = 101 unless otherwise specified. RT-PCR, reverse transcriptase PCR. Symptom grades: grade 1 (mild), mild symptoms causing no or minimal interference with usual social and functional activities with intervention not indicated; grade 2 (moderate), moderate symptoms causing greater than minimal interference with usual social and functional activities with intervention indicated; grade 3 (severe), severe symptoms causing inability to perform usual social and functional activities with intervention or hospitalization indicated; oxygen administered via nasal cannula; grade 4 (potentially life-threatening), potentially life-threatening symptoms causing inability to perform basic self-care functions with intervention indicated to prevent permanent impairment, persistent disability, or death; hospitalization requiring intubation or use of supplemental oxygen (continuous positive airway pressure [CPAP] or oxygen administered via mask).
