It’s probably more correct to say that the current mortality rate of hospitalized cases is 3%.
And “IF” the researcher is right that only 5% of the cases have been confirmed. Then that might drop the mortality rate to 0.6% mortality. Which would be good news for everyone. The bad news is that there are 24,500 people now spreading the illness insted of 1300.
Excellent!
Of course it’s ‘early days’ so who knows... anything.
