But this is not how it is dealed with.The case fatality ratio refers to the percentage of people with a given disease who die of that disease. In this instance, the disease is COVID-19, so you have to have the symptoms of COVID-19 in order to be a case.
Both numbers of the relationship are reported higher:
As case counts everyone who has shown been to have the virus. At least in Germany this is the way they deal with it, and I doubt that other countries split their numbers (already).
Same with death, you die "from Covid-19" when you have the virus, regardless of other diseases.
Definition-wise the infectious fatality rate doesn´t shed a clear light on the case fatality rate. https://en.wikipedia.org/wiki/Case_fatality_rate
The term infection fatality rate (IFR) also applies to infectious disease outbreaks, and is closely related to the CFR, but attempts to additionally account for all asymptomatic and undiagnosed infections.[7] The IFR differs from the CFR in that it aims to estimate the fatality rate in all those with infection: the detected disease (cases) and those with an undetected disease (asymptomatic and not tested group).[8] (Individuals who are infected, but always remain asymptomatic, are said to have "inapparent" — or silent, or subclinical, or occult — infections.) The IFR will always be lower than the CFR as long as all deaths are accurately attributed to either the infected or the non-infected class.
So it´s about detection and not about symptoms, might it be in this or that scenario reasonable or not to count
symptoms or positives, respectively, as case.
In other words, its up to you how you detect a case (by symptoms or even by a test), however, the infectious rate relates simply to the non-detected ones (because here may be NO symptoms and may have been NO tests).
