Coronavirus disease 2019 (COVID-19) is primarily a respiratory virus and there is no evidence of transfusion transmission for COVID-19;1, 2 however, estimation of the seroprevalence rate of antibodies to severe acute respiratory syndrome coronavirus 2 (anti-SARS-CoV-2) in blood donors' population reflects the progression of the epidemic in the region. It is unclear how many people have contracted the virus since only symptomatic cases have been registered. For this reason, and as a part of the National Centre for Disease Control preparedness plan to combat the spread of the COVID-19 infection in the Tobruk region, eastern Libya, we conducted a cross-sectional study between January 15 to February 15, 2021, six months after the identification of the first confirmed COVID-19 case in the region on 23 July 2020. 3.
