Ebola doesn't 'target' humans. Ebola's obvious symptoms and mortality rate in humans limit its ability to spread efficiently. The flu virus or cold virus has been far more successful in penetrating the human ecosystem. Perhaps Ebola has been selected for being stable in the bat ecosystem. The mobility of bats also makes them an excellent transmission vector, which a virus would ideally want to be non-symptomatic.
