The 1% is the working hypothesis that PH is working with assuming they manage the containment stage successfully as China (removing HUBEI) has - so far. 0.85%

More than 8 times seasonal flu

Lots of places the numbers don’t make sense
The WHO were originally saying a working hypothesis 0.7% at the lower end with good management.
I see Dr Phillips Whitford has just said 1% too
