Are Experts Worried that Ebola Could Become Airborne?

From this New York Times article:

 Officials said medical experts in the government were genuinely worried about the possibility of a mutation that could turn the virus into a more contagious sickness that could threaten the United States.

I'm not sure what "a more contagious sickness" would mean, other than one that became airborne.  Can anyone think of an alternative meaning?
