In this presentation we provide the evidence that dengue fever is transmissible through blood transfusions. A discussion can be found at The Brazilian Blood Journal.

The region is seeing more cases of dengue and hemorrhagic fever, a life-threatening complication of the mosquito-borne virus, than in past.

That finding was surprising, because most dengue cases are imported from other countries, officials said . “These were the first cases that were locally acquired,” said Dr. Brian Smith, regional director for the Texas Health Services’ Region 11, which includes the Valley. The findings suggest that dengue’s reach is growing beyond its usual borders…
