What can the virus Ebola do to the human body,once the body has become infected???

Ebola is a viral hemorrhagic fever. There is no vaccine available to treat it, people infected receive supportive treatment to try and counteract the effects the virus has on the body. It is a category 4 pathogen. Many people who become infected with it will die due to multi organ failure or shock, as it has a high mortality rate. Death will normally occur within 7 -14 days of infection. Infection normally occurs through transmission of bodily fluids.

The symptoms include high fever, headache, dizziness, joint pain, nausea. The next stage is diarrhoea with blood, vomiting with blood, red eyes due to the swelling of blood vessels, rash on skin due to bleeding underneath, then internal and external bleeding from just about every area of the body. This causes organ failure resulting in death, shock can also kill as the body is over whelmed due to everything that is happening, it basically can't cope and shuts down.
