TL;DR: Wuhan Blood Center as mentioned in this paper screened donations in real-time and retrospectively and found plasma samples positive for viral RNA from 4 asymptomatic donors, which is the first screening for severe acute respiratory syndrome coronavirus 2 RNA.

TL;DR: This study indicates that the S‐RBD‐specific IgG antibody reaches higher levels after 4 weeks from the onset of COVID‐19 symptoms, and recommends the following selection criteria for optimal donation of CO VID‐19 convalescent plasma: 28 days after the onsetof symptoms and with a disease presentation of fever lasting longer than 3 days or a body temperature exceeding 38.5°C.

TL;DR: In this paper, the seroprevalence of SARS-CoV-2 antibodies among blood donors in the cities of Wuhan, Shenzhen, and Shijiazhuang in China was investigated.

TL;DR: From February 9, all blood establishments in Hubei province, China, implemented nucleic acid testing (NAT) for SARS‐CoV‐2 RNA among blood donors to ensure blood safety.

TL;DR: The prevalence of antibodies to SARS-CoV-2 among blood donors in China was low, even in Wuhan city, and effective public health measures are still certainly required to block viral spread before a vaccine is widely available.
