Seems like it is so mild the person doesn't even need to be in the hospital. He called ahead to a clinic to be assessed. Doesn't sound like he just walked up to the ER.

Overall, the virus seems more infectious than SARS but less deadly. People may have very mild disease and not aware they have it.
It doesn't fly in the air and stay there. It will settled to the ground or a surface.
Practice good public hygiene, wash hands often, use hand sanitizer, avoid touching your face. Wearing a mask may not filter everything, but it avoids you touching your face and that is good.
We should encourage people to get tested and contain it whenever there is a case. Stigmatization will make things worse. Last thing you want is people trying to hide it until it is too late.
It is expected it will spread, like any other virus. The difference is people are more vigilant and ask to be tested and there is a test. That's how you get flu, cold, all the time, every yr.
SARS eventually disappeared because it ran out of host, either through contact precautions, death or naturally immunity/recovery. This one will also subside eventually. It is an emergency in China. But WHO hasnt announce it to be global emergency yet.
I left Vancouver 2 nights ago on a Cathy Pacific flight, and I wiped down every surface on the seats and wore a mask. Every flight attendant wore a mask too.
I am flying back next weekend for the Sedins game. Ain't no virus keeping me away!
