The numbers I have seen is 15% of those who have the disease are hospitalized.
However, there may be different criteria in different countries over what gets you into the hospital.
I think the percentage may be lower because some folks may have such minor symptoms in the general population that they may never get tested.
I’m hoping that we don’t have the medical system issues that seem to be present in Italy and SK.
I’m hoping all that happens is the already present supply chain issues.
