Where do you see that rate in your source? You seem to be off by an order of magnitude.

Edit: I misread your qualifier of "under 50 age group". Overall fatality rate seems to be around 0.4% according to the CDC site.

The over fatality rate is actually lower since that listed rate only applies to symptomatic patients. Given their estimate for Asymptomatic 35% you arrive at 0.26%.
