SUBDUCTION ZONES and ISLAND ARCS. Subduction Zones are where cool lithospheric plates sink back into the mantle. It takes about 50 my for the ocean lithosphere that formed in the hot (>1000C) environment at mid-ocean ridges to cool to an equilibrium state and sink to its maximum depth below sea-level.
Ebola hemorrhagic fever is a viral disease caused by Ebola virus that results in nonspecific symptoms (see symptom section of this article) early in the disease and often causes internal and external hemorrhage (bleeding) as the disease progresses.
For people with Ebola, treatment involves providing relief of symptoms while the body fights the infection. This is known as supportive care. Intravenous fluids, antibiotics, and oxygen are usually employed. Treatment may also include the use of medications to control fever, help the blood clot, and maintain blood pressure. Even with such supportive care, death occurs in 50 to 90 percent of cases.
