There are lots of "case fatality rates" for #COVID19 now but the best measure may be China ex-Hubei (incl HK + Macau) because the spread there mostly stopped weeks ago. Today it is 0.9% (113 died out of 12,117 who died or recovered) of confirmed cases. Normal flu around 0.1% 
This does NOT mean that 0.9% of those who get the coronavirus are likely to die. The UK government seems to assume 20% of Hubei province (ie 12m out of 59m pop) got the virus but only 0.1% of Hubei were tested positive. Confirmed cases may be a tiny % of those who get it
The fatality rate of the #coronavirus will vary between countries depending on the quality of health care, whether the health system is overwhelmed (Iran, Hubei) and the age structure of the population
