China has 80k cases and already around 2900 deaths. Even if nobody would die anymore they would have a death rate of more than 3%. Italy has 50+deaths with 2k cases which is also already a rate of 2.5% even if nobody else of the infected would die.
Some countries may have a lower death rate but where in the world did they get 0.2% from? Maybe if they learn better how to handle it but right now it's much above that.
Sure, we will have undetected cases as well but I would be surprised if the death rate is below 1%
