This is a strange coronavirus in that some get sick and some don't. And a lot of people know of no one that actually has or had it, so for many people this isn't anything to worry about or take seriously in their minds.
OK, I've read your post so far (and I will read on) but feel compelled to answer just to the first two sentences immediately.
I saw a story on TV about a guy who got deathly ill, ICU, close to dying. He was a muscular 175 or so when he went from San Francisco to Florida for a conference type affair. He was a complete stud, they showed his picture. I think he was less than 30, a nurse. He figured he'd be OK when he went. This was when things were just starting to get pretty dicey, but not by much. It was probably around the beginning of March. They showed him after 5-6 weeks in ICU, probably on ventilator much of the time. He'd lost 40-50 pounds. He looked like a skeleton. But he survived. That picture of him before, he looked like the perfect picture of health. He had no known risk factors.
Point is, this can attack anyone. There may be genetic vulnerabilities they don't know about. There are many 20-30 year-olds with similar stories, some of whom have died, no doubt.
I don't personally know anyone who has contracted covid-19, but I take it very seriously. It's likely that there are people I know who have had it. Maybe they never knew they had it, maybe they didn't want to advertise it. There's probably double digits people I know who have had it, symptomatic or not.
The thing with this is the R0 factor is so high and with its asymptomatic and pre-symptomatic spread and potential to overwhelm the health care systems and bring the economy to its knees it should/must be instilled in the public mind that it's the duty of all sentient people who are responsible for themselves to not make the situation worse by being hapless vectors, passing it on to 2-3 or more people as is the average.
And look, this isn't just a question of life or death. Just because covid-19 doesn't kill you doesn't mean you just get over it like the flu. This fucks people up, and in more ways than any other disease in history. It leaves a lot of people with permanent lung damage, scaring that will never heal. There are so many other awful things that this causes. Watch this:
