I especially have a hard time attributing arrogance and selfishness to someone whose actions treating Ebola patients, for months apparently, are essential to actually containing the spread of the disease. He might pay for that with his life. A trained physician relying on the best available science about how the disease is spread and when he's at risk of spreading it is what we should expect. What he failed at was PR in a panicked country. If there's anyone to blame for that, it is the PR hacks and political people, not the doctor.
And it's fine to be concerned about something becoming airborne, but that hasn't happened. HIV mutates and 'could' become airborne, but we don't treat HIV as an airborne disease because it isn't. Ebola is no different - there's a risk according to experts, but it hasn't happened yet, so public policy need not treat it as an airborne threat.
