#COVID19 why is mortality rate defined as ratio of total deaths to total cases (today: ~50k/1000k globally = 5%)? Shouldn't it be ratio of total deaths to total_deaths_plus_recovered (~50k/250k = 20%), since only then are we comparing cases that have reached a conclusion? (1/n)
In other words, even if COVID19 spread were to abruptly stop today, many of the 750k active cases will still end in death, unfortunately. That will proportionally increase the numerator from 50k; will that lead to higher mortality rate? Where am I making a mistake? (2/n)
