Is the Ebola virus anaerobic or aerobic?

It could be both, depending on the host the virus is infecting.

"Viruses do not have the ability to respire on their own. They need to use the mitochondria of their host cells in order to use the process of respiration of the cell they have invaded. So, in other words,you could say that viruses "borrow" the respiratory ability of a cell, and that can be aerobic or anerobic, with or without oxygen.”
