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 generally starts with flu-like symptoms. Though it's known for the extreme hemorrhagic symptoms -- the bleeding out of the eyes, etc. -- not everyone will experience these. In fact, only 20 percent of people will have [these extreme symptoms] Bhadelia said.
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.
