Tough question. It depends on your personal situation. As a healthy young non-smoker* your personal risks are financial first, injury or unrelated illness during the height of the outbreak second, supply shortages third. All three problems come from the same source. Our countries are aggressively optimized toward more typical conditions, so we’ve become very bad at dealing with crises. That’s why your personal risks are where they are.
Collectively, pretty much everybody’s gonna get this thing, it’s just a question of when. It’s also pretty much guaranteed that our healthcare systems (optimized for flu season) aren’t going to be able to handle it. But the fewer people sick at once, the lower the death toll is going to be. That’s the priority right now. So you have a social responsibility to wash your hands and to stay home if you’re sick. Statistically, if you don’t avoid spreading it (by e.g. going to work when sick) you are literally killing 1 person.
So, I dunno. It’s concerning? Panic isn’t helpful. But you should probably change your behaviour for a little while, especially if you’re the kind of selfish slob who goes to work sick and doesn’t wash his hands.
