Well, let me migrate and comment on this recent post from one of the original Ebola threads:

It seems to indicate that it is possible to contract this bug without direct contact.

That's an often cited experiment done recently in Canada. I just wanted to repeat the caveat that Ebola affects pigs differently than humans. As the study authors mention in the article itself, in pigs, Ebola can infect the respiratory tract and virus was detected in oro-nasal swabs. Virus was not detected in the swabs of infected macaques, which is what you would expect because Ebola is not a respiratory disease in macaques (or humans).

So, the main thrust and take away message from that particular experiment is that pigs can be a vector for Ebola that does not require direct contact. So stay away from any Ebola-infected pigs.

The study authors also note that infected macaques did not seem to be able to infect macaques in other cages, so the spread was limited to pig-to-macaque transmission.
