Analysis of current SARS-CoV-2 infection in a large population of blood donors evidenced that RNAemia is rare in plasma.

Background: Transmission of SARS-CoV-2 by asymptomatic individuals and by blood transfusion are important issues to understand to control the viral spread. In this work, we estimated the current SARS-CoV-2 infection rate in blood donors from Belo Horizonte, Brazil.

Study Design And Methods: Saliva and blood samples were collected from 4103 blood donors from June 15 to September 30, 2020.

Confidential donation confirmation as an alternative to confidential unit exclusion: 15 months experience of the HEMOMINAS foundation.

Background: Confidential unit exclusion remains a controversial strategy to reduce the residual risk of transfusion-transmitted infections.

Objective: This study aimed to analyze confidential unit exclusion from its development in a large institution in light of confidential donation confirmation.

Methods: Data of individuals who donated from October 1, 2008 to December 31, 2009 were analyzed in a case-control study.
