Use your initiative and be proactive, volunteer to quarantine yourselves if you believe you have had contact with infected people known or unknown, do not wait till you developed rashes than you start to quarantine yourselves, it may already be too late and you may also have broken the law by knowingly or unknowingly passing on contagions.
You can't actually break the law by passing on contagions if you don't know that you have them.
Anyone who thinks that this is going to be contained by "quarantining" after people exhibit the symptoms is naive in the extreme.
Most people will have effectively spread the virus LONG before they get developed symptoms and of course those people cross infected will do likewise.
As the Chief Health minister said, "It may be better to simply treat this the same as the seasonal flu".
Unfortunately, just like the "Global warming" hysteria, there are those that think that we as humans can actually do something about a phenomena that's completely out of our control.
As George Carlin would have put it "It's the ultimate arrogance of our species"
