Re: Coronavirus. Are you buying the hype?
You're correct. CFR only examines cases that have reached a final disposition.
CFR = # of deaths ÷ (# deaths + # resolved)
If you look at this page, in the lower left hand corner, there's a graph of the cumulative number of cases. The denominator in the CFR calculation today would be 3,119 resolved cases. That number of cases threshold was crossed around 27-Jan (11 days ago). The question that has been in my mind is why the number of resolved cases reported is so low. The information that we've been given is that most young and healthy people "recover within a few days". If that's the case, why isn't the number of recovered patients higher?
The press has been saying that the mortality rate is 2% and you're absolutely correct- that is a premature measure. If someone tests positive after exposure but it takes 5-10 days for them to show symptoms and another week to reach a final disposition (death vs recovery), then that low death rate might be premature because of the length of time that it takes between diagnosis to final disposition.
My understanding is that a case fatality rate is based on cases of infections that have run their course -- resolved, death, etc. Not those recently infected with unknown outcomes. Based on that, I think the cfr is around 30%. This virus has an especially long clinical period -- onset of symptoms to recovered or not recovered -- so we just don't know for many of them. Plus, the data sources aren't considered very reliable.
