Some of these fluids leak into the lung, so someone can die by drowning in their own fluids. The sweating from the fever, the internal bleeding, and the leaky tissue causes severe dehydration, causing the body to go into shock. The body cannot live without fluid and blood to feed the brain tissue. Organs also stop functioning. Most people become unconscious at the end so they are not aware of the experience they are having.
Most victims die from shock after days of high fever, chest pains, vomiting and extensive bleeding.
Patients who are intensively treated with replacement fluids can survive the ordeal.
