ELI5: What exactly is Ebola?
gpt
Ebola is one of several viruses known as *Hemorrhagic*.  Hemorrhagic is a big word that means bleeds a lot.  Bleeds a *scary* lot.

The way this virus kills a body's cells is it ruptures (explodes) the cell walls.  All of your cell walls begin exploding.  The cells guts leak out.  This effect begins in your blood and works itself deep inside.  It begins affecting your organs through the blood.  It spreads everywhere.  Unlike some viruses that like certain areas or tissues, this stuff is nasty pervasive.  It goes everywhere.

*BOOM!*  Cell walls go.  What this means is eventually your body can't hold all the blood anymore.  Your veins and arteries, your capillaries, all of them leak.  Your organs leak.  Everything's leaking.

This effect begins to be noticeable within days of infection.  Along with the high fever and cough, deep bruising begins to appear as the body starts leaking blood into surrounding tissues.

Ends with people bleeding from eyes, nose, mouth.  Everywhere there's an opening a person will bleed from it.

That's one of the scariest parts of the virus.  The bleeding everywhere.  Scary stuff.

Hope that helped some.
