The current mortality rate is ~3%, but that's based off of confirmed cases. It's estimated that ~80% of cases will have light symptoms or no symptoms at all. Those cases will go largely undiagnosed.
The actual mortality rate is probably closer to 0.5%. That doesn't sound that bad, but the flu mortality rate is under 0.1%. Plus the flu has vaccines & treatments. It doesn't typically require prolonged hospitalization.
The mortality rate is likely much lower than what's being advertised, but that doesn't necessarily mean that we shouldn't be taking actions to keep our healthcare system from being overwhelmed.
It doesn't matter. All that matters is the rate of hospitalization and the deaths. If you can't put these people on ventilators then we will see 100s-1000s of deaths each day. It's pointless to predict. You're not an epidemiologist. I doubt your one semester of Stats 101 is helpful here.
COVID-19 hospitalization rates are 4x higher than seasonal flu. 45yo AT&T Director was on a ventilator. Guy runs the Austin Marathon every year and he coded last night. He's stable.
