Blood Donor Recruitment During Epidemic of COVID-19 in Guangzhou, China

In December 2019, an unknown pneumonia rapidly spread in Wuhan, China, a new coronavirus, 2019 novel coronavirus (2019-nCoV), aroused the attention of the entire world. On January 31, 2020, World Health Organization (WHO) announced the outbreak of Coronavirus Disease 2019 (COVID-19) in China as a Public Health Emergency of International Concern. The number of volunteer non-remunerated blood donors decreased because of quarantine, caring for relatives, and fear of exposure to COVID-19. Due to the blood shortage, patient blood management and cessation of elective surgery are contributing to decreased demand, but sepsis may increase requirements and significant reductions will not be possible in areas such as trauma, cancer patients, hereditary haemolytic anaemias and childbirth. Therefore, recruiting enough blood donors during the epidemic is vital for public health in China, and also worldwide. In order to assess the effects of a questionnaire on blood donor recruitment, the investigators designed two kinds of self-administered, standardized and structured questionnaires. In addition of the basic socio-demographic characteristics, one questionnaire includes the information of precautions of blood donation during epidemic, and the other dose not. The questionnaires were randomly sent to ever blood donors, and the same number of ever blood donors are coded as control.
