It doesn't behave like the flu. The people I know who have had it say it is scary. I know one guy who has rotated through it several times, getting better and then relapsing. Relative healthy guy in his forties. Scared the hell out of him.
Have to wonder if this is a designer bug.
You've just captured the essence of Covid, in a nice concise manner. It's not generally a highly lethal virus, but it does some strange things - sometimes in healthy younger people, that is unpredictable. That's why all the hype (in addition to the politicization by the left). I personally believe that you are touching on the truth when you ask if 'this is a designer bug?'. I don't think it was designed, per se, but was the result of gain of function mutations (most specifically to the spike protein - which defines infectivity and range), and that this created a 'funky' virus that has properties you wouldn't expect to see in a rapid evolutionary sense.
Even a lot of the people who recover probably are going to have had their health damaged for the rest of their lives.
The disease is not a nothing-burger - and no I don't support totalitarian lock-downs.
It starts out more deadly than the flu for the young and just gets worse from there.
In Maryland, the death rate of those between 10 and 29 is 0.189%—higher than the influenza death rate. It increases with age. In the 50-59 age bracket, 1.9% of those who contract Covid-19 die. A whopping 28% of people age 80 and up die.
It does not behave like influenza at all. It affects multiple organs, destroys the lungs and heart. Terrible.
