That's why call out every twitter thread like that when I come accross them. In this case it was a guy you referenced a friend of his. So uncorborated. Bad reporting, plain and simple.
If people refuse to take it seriously, no amount of reporting will change these individuals behaviour. What it does so, is causing overreaction of others which can have kind of side effects. Ranging from funny to plain dangerous.
I'm not sure if you can overreact to that, to be honest.
But people in countries that aren't at that stage yet think it won't be so bad there. Because it's all fake and second-hand information, not well sourced, and therefore probably not true and so we shouldn't overreact. Wrong! You should take precautions now, while you still can.
Because what is described in the thread fits completely with an exponentially growing disease that everyone seemingly gets at once and thus completely overwhelms the hospitals. You shouldn't try to shush people who point that out.
This will get much worse, but it's still worth maintaining some perspective.
Even if you yourself aren't vulnerable, you're potentially screwing up people's lives. Not just vulnerable elders, but also doctors who, for better or worse, are unconsciously taken advantage of by requesting them to overwork themselves in poor conditions. The alternatives to not having them overwork are coordinated efforts (which increases contamination, and requires serious coordination that hasn't been shown in Italy yet if the stories are to be believed) or simply leaving people to die. How many people do you think truly understand the consequence of their actions and would willingly continue to do so with full knowledge?
And for what? Some abstract concept called "economy" that 90%* likely won't feel a thing of? Isn't it at least a little ironic that we aren't allowed to panic about corona, but are allowed to panic about anything potentially affecting the economy 'negatively', which just as many people don't know anything about, including tons of self-proclaimed experts?
* Disclaimer: This statistic is indeed picked randomly.
I feel like a wingnut even writing that. My opinion would change except lots of health experts and all the smartest people I've talked to on this seem to agree.
