SARS-CoV-2 Found in Blood – Is it Transfusion Transmissible?

April 15, 2020

Researchers in both China and South Korea have identified SARS-CoV-2 in routine blood donations. In China, 2,430 blood donations (1,656 platelet and 774 whole blood) collected between January 25, 2020 and March 4, 2020 were screened by real-time reverse transcription PCR for SARS-CoV-2; in addition, almost 5,000 samples collected between December 21, 2019 and January 22, 2020 were retrospectively tested. Four samples were positive for SARS-CoV-2. All four blood donors were asymptomatic at the time of collection, but two developed fevers the day after donation. In South Korea, seven donors who later tested positive for SARS-CoV-2 (6 -15 days post-donation) were identified by the South Korean Centers for Disease Control and Prevention, and the South Korean Red Cross Blood Services were subsequently notified. All seven samples (6 whole blood and 1 source plasma) were negative for SARS-CoV-2 RNA. However, 6 platelet units and 3 RBC units had already been transfused into 9 patients. Eight of the transfusion recipients did not develop symptoms related to COVID-19, and the 9th died of causes unrelated to COVID-19. No transfusion-transmission of SARS-CoV-2 has been observed in China or South Korea, but medical staff and blood collection establishments must remain vigilant and in close contact with donors and health authorities for cross-referencing SARS-CoV-2 positive donations and recipients. Further research is needed to confirm the presence or absence of virions in blood products and whether these virions are infectious.

Anemia Treatment and Erythropoietin therapy Guidelines

Protocol based on scientific evidence for the non-transfusional treatment of anemia through the appropriate use of iron and erythropoietin.

Welcome to Bloodless


Blood transfusions are currently one of the most performed medical procedures in the world. However, the medical literature shows a relationship between the use of allogeneic (donated) blood and greater complications, including, greater mortality. Worldwide, there is a deficiency in medical knowledge about transfusion practice.


1. To change the current transfusion practice, through the application of scientifically safe and effective PROTOCOLS for the TREATMENT OF ANEMIA and MANAGEMENT OF BLEEDING without the use of allogeneic blood, based on the scientific evidence of modern medicine.

2. Help blood banks SAVE their main HEMOCOMPONENTS (red blood cells, plasma and platelets)
