Organ Transplant From SARS-CoV-2–Positive Donors: A Brazilian Experience

Since March 2022, donors with detectable SARS-CoV-2 RNA have been accepted for extrapulmonary organ transplants in Brazil. In this report, we described 11 successful organ transplants (6 kidney, 5 liver) from 5 asymptomatic infected donors.

Surveillance of donated blood during the 2016 arbovirus outbreak in Brazil.

Reports of arboviral transmission via blood transfusion may be a cause of concern among asymptomatic infected donors. This study evaluated the presence of arboviruses in donated blood products during the 2016 outbreak in Vitória da Conquista (Bahia-Brazil). Serum samples (n = 676) were screened for ZIKV, CHIKV, and the four DENV serotypes using a one-step reverse transcriptase-based Real-Time Polymerase Chain Reaction (RT-PCR). No samples tested positive for any of the targets, whereas positive controls performed as expected. The results suggest a low risk of arboviral transmission via transfusion of blood products in the endemic area studied during the 2016 outbreak.
