Dengue outbreaks may threaten blood transfusion safety

More than 1000 confirmed clinical cases were reported during the Queensland outbreak of 2008–09, although the true incidence was likely to be higher due to asymptomatic infection, according to new research.

Using whole blood samples collected during the Queensland outbreak, researchers calculated the risk for a dengue-infectious blood donation to be around 1 in 7146.
