>Sure, but we know the flu is deadly and relatively communicable and we certainly don't take this level of precaution.

The death rate for the flu averages around 0.1%. The Wuhan virus is currently just over 3%, the 1918 flu that killed millions had a death rate of around 2%. The flu is deadly, the Wuhan virus is currently 30x deadlier than the flu. Additionally, flu vaccines already exist as well as anti-virals that have been shown to work on the flu. There is no vaccine for the Wuhan virus nor am I aware of any anti-virals that have been shown to work on it.
