Yep, in general terms I think safety procedures should and can be adopted, but having a watch list is something too detailed to happen, I don't think they can put everyone there.
I think they are now taking it seriously. I was impressed with New York's immediate response to the infected doctor. Unfortunately, I think they have to tippie-toe around the situation because here people cry foul at every opportunity. Look at the nurse who wants to sue for her enforced quarantine. You would think she'd be more interested in keeping the people around her safe.
I think that they were already taking it seriously, but it's just something they don't know how to deal with, so it's generating some chaos, I hope this can get under control soon enough.
I think that the media is really making the whole situation worse. Yes, we have the right to be informed, and yes the government has the right to try and stop the spread through quarantines, but the media paranoia is getting ridiculous.
