March 17, 2020: Which airline does the virus use?

These words are being typed at Melbourne airport while I wait for a flight. As I look out at the planes arriving I can't help wondering if they are carrying the virus.

I feel concern for aircrew whose jobs have become so risky since they come in contact with passengers from all over the world - including places which have been slow to introduce quarantine restrictions.

Just as schools have been closed and so many activities have been cancelled around the world, so also airline activity will need to be greatly restricted if the virus is to be stopped from spreading.
