The virulence of this virus is currently estimated to be between 1.4-6.5 with a median estimate of 3.8%. To put this into perspective, the seasonal flu has a virulence of around 1.3%. In simple terms, this means that it spreads significantly faster than any known seasonal flu.
As for the death-rate, the CFR currently stands at around 3.8% (after excluding the Chinese reported CFR that many, including myself, see as being cooked). This is multiple times greater than the CFR of any seasonal flu (which is around .1%)
In addition to this, around 10% of cases require hospitalisation, which is more than 10 times the number of the seasonal flu.
There's no need to panic, but pretending that this is just another seasonal flu is an issue.
Wash your hands, don't touch your face, and limit person-to-person contact.
