When the virus attacks the body it starts copying it self. How does it copy it self? The virus doesn't have a complete organic system, so it uses the DNA and RNA duplicator in the cells of the body to duplicate its RNA. Now when the RNA of the virus is in thousands in number, it takes control of that cell. After it take control of that first cell, it start to move to other cells in big numbers, until it takes control of the whole organ. At that moment the DNA of the body stops working, because the DNA in fo virus took control. When it takes control, it does what ever it wants to the body. There it start.
