Hemorrhagic fevers like Ebola are extremely fatal — they kill up to 90 percent of people infected — while SARS, a coronavirus, has a lower mortality rate but spreads incredibly rapidly.
A more serious presentation is neonatal purpura fulminans, which is when a newborn with protein C or S deficiency suffers massive arterial and venous thromboembolisms with hemorrhagic skin necrosis.
A hemorrhagic stroke is normally caused from an aneurysm and is treated differently that we treat strokes from a blockage of a blood clot, or a fatty clot.
The Centers for Disease Control and Prevention says a patient being treated at a hospital in Dallas, Texas, is the first diagnosed in the U.S. with the hemorrhagic fever.
