I read elsewhere the incubation period was only 3 days. If it's actually 5 to 7 days this vector could be so very much more dangerous.

I agree, this looks like the much predicted super-flu that hops out of Asia every few decades. Not a lot of deaths so far, but treatment requires a high degree of medical attention. It has a real possibility of totally overwhelming health care services wherever it strikes.

"When" this hits the States, look for a run on medical masks and large numbers of people choosing to stay home.
