Abstract
Since the outbreak of SARS-CoV-2, it has spread rapidly around the world and caused a serious global social crisis. During the epidemic, the blood collection and supply industry have been greatly impacted, due to the sharply dropped blood donors and transfusion transmission risk of SARS-CoV-2. Many infected individuals are asymptomatic and they may donate blood without awareness of the infection or before symptoms appear. In addition, viral RNAs have been detected in the blood of some patients infected with SARS-CoV-2. Although no infectious SARS-CoV-2 virus was found in the blood nor the blood components, there is a risk of transmission through blood transfusion which may endanger blood safety, especially during the pandemic period. This review briefly introduces the biological characteristics, epidemiology of SARS-CoV-2, with a particular focus on SARS-CoV-2 infection and blood safety.
