I can tell you that I went to a hospital here in NJ last year with a fever. They decided I had the flu and kept me in isolation for two days. (Yes, I had had a flu shot.)

How long is the asymptomatic i.e. contagious period for the flu as compared to c-virus?
And as DouglasKC pointed out: this virus put 15% to 20% in the hospital and 10% of that in ICU.. did the flu behave the same way?
