Most dengue virus (DENV) infections remain asymptomatic. This increases the risk of DENV transfusion transmission (TT‐DENV) during outbreaks. We evaluated DENV viremia in 8475 blood donations assembled in minipools for the presence of DENV RNA. The tested samples were obtained between February and May, 2016, during a large DENV outbreak in Ribeirão Preto city, northeast region of the São Paulo State,...
BACKGROUND
In 2015, there was a large Zika virus (ZIKV) outbreak in Brazil. The proportion of asymptomatic infections is very high, and it is possible for transfusion‐transmitted ZIKV (TT‐ZIKV) infection to occur. The prevalence of asymptomatic ZIKV infection among Brazilian blood donors during this epidemic outbreak is unknown.
STUDY DESIGN AND METHODS
Plasma samples obtained between October 2015...
