BACKGROUND Blood centers (BCs) rely on schools and businesses. Shelter-in-place orders closed them. This study determined how COVID-19 affected donation habits. STUDY DESIGN AND METHODS Two periods were reviewed (May 1 through June 30, 2018 vs 2019 [control] and 2019 vs 2020 [study-COVID period]). These donations were reviewed: first-time, repeat (donation ≤ 2 years), and lapsed (no donation > 2 years); sex; age; ethnicity; and ABO blood groups at high school and college drives. Testing all donors for SARS-CoV-2 antibodies started May 18, 2020. RESULTS In the study period donations significantly increased (control P = .683, study P ≤ .0001) and comparing sex (control male P = .716, female P = .657; study male P = .004, female P ≤ .0001). In the study period there was a significant decrease in Hispanic (P = .001) and African American (P < .0001) donations also seen among high school and college drives and an increase in Caucasian (P < .0001) donations. There was a significant increase in first-time (P < .0001) and lapsed donors (P < .0001) in the study period vs control (first-time P = .087, lapsed P = .308) and a significant decrease in donors not more than 30 years (study 16-20 P < .0001, 21-30 P < .0001). There was a significant increase in all blood types in the study period (P < .0001) and in donations after implementation of SARS-CoV-2 antibody testing (P = .001). CONCLUSIONS Significant changes occurred in donation habits in the study vs the control periods. These included increased total donations, comparing sexes, first-time and lapsed donors, all blood types, and Caucasian donations. Significant decreases were seen in Hispanic and African American donations and those not more than 30 years old.
