I am not a doctor, but I frequently play one on the internet. That being said I will now tell ya what I know about "Recovery might or might not confer immunity".
What it means is that your body has beaten the bug once and may or may not do it again. Past performance is not an indicator blah blah blah. In short, if you survived it once, you certainly stand a better chance than those who did not survive it the first time. (duh?)
In any case, there have been worse things. Smallpox killed a ton of folks. My Great grandma got it. Got over it and was immune. She was lucky, or just possessed the right genes.
There was an article I read this morning about some scientist types who found covid 19 on dust particles (pollution). I don't know how they found time to chase that down, but they say they did. If it is true, we are all going to get it sooner or later. Some of us are not going to even get sick, others are going to die.
...And this morning the CDC found six more symptoms of the Corona Virus. As if the nations hypochondriacs aren't already convinced that the grim reaper is beating on their door demanding to be let in.
...went to my barbershop yesterday to get a haircut. There was a couple more folks standing around waiting on them to open. They didn't open. Seems the barbers are more afraid of their customers giving them covid than the opposite. Then again, who knows how much "not cutting hair" pays.

Liberals are like a "Slinky". Totally useless, but somehow ya can't help but smile when you see one tumble down a flight of stairs!
