I traveled to Scotland end of September 2019. Got sick while there and then flew home. Sicker than a dog for weeks. My traveling companion said...I’ve never seen anyone so sick with a cold/flu. After they started talking about Covid I figured that’s what I had. Doc did an antibody test on me recently and it came back really low. So if I had Covid would I still have the antibodies from it? Apparently not. And, I got the J&J and got very few antibodies from it. So now I’m in wait and see territory to see if I eventually get it. ugh

Re: "I don't get the 0.8 death rate when mortality was 1.8% overall? And right now is 1.7%. Is that a typo?"

No - there are at least three ways to calculate the Fatality Rate.

(1) Using the Confirmed Infection (tested) rate

(2) Using the Total Infection (estimated and non-tested) rate

(3) Using just the Symptomatic Infection rate

The Fatality Rate for influenza each year uses the Estimated Symptomatic Infection rate.

For Influenza, the average annual Fatality Rate is around 0.1%.

In a severe influenza season, the Fatality Rate is around 0.2%.

I do not know how they calculate the 1.8% COVID rate - most likely they use the Confirmed Infection Rate.

The 0.8% and 0.3% COVID rate mentioned in this article most likely comes from the Total Infection (estimated) rate.
