The data they use is 16 days old.
Crunching real time data from Johns Hopkins...
Outside of China, which includes a lot of Third World countries, the death rate per confirmed infection is 0.7%.

For comparison - an “average” influenza season in the USA has a total morbidity rate of 0.2%.
I think the corona death rate outside China will continue to drop since we are basically counting the most serious cases at the moment.
The unknown problem - how contagious is it?
Even with a very low death rate, if the corona infection rate is very high, then a lot of people will die.
Hope for low fatality rates, plan for high.
Too many unknowns at this point.
Precedent points to likely quarantine, be it to actually stop spread or just to reduce demand on medical infrastructure by slowing inevitable spread. Be ready to just stay home for a month with zero outside contact. Many jobs & schools can telecommute.
You can’t look at “total cases” because most of those are still sick, and some will die.
Even then, 2800 deaths over 82000 confirmed cases is closer to 3%.
