My company just shut down all travel. We are a global company that is feeling the supply-chain problem first hand as we have many parts made in China. We're actually better prepared than most, but it's a real problem, especially for my team who travels the globe doing in-person training. That's all being canceled, rescheduled, or converted to virtual. If you're glibly discounting this whole thing, I'd advise you to wake up.
It doesn't matter what the death or spread rate of the virus is at this point. What matters are the repercussions because, like it or not, perception matters more than reality. It always has, and it always will. If people are hoarding hand sanitizer and toilet paper now, it's a VERY short leap to people hoarding food. Do you know what happens if truckers stop driving? Or the super-market cashiers stop reporting to work? There will be food riots in about three days because our "just in time" inventory systems are not designed to handle a problem of this scale. If we're lucky, automation may actually save us, but things can go bad FAST.
BTW this is the shelf for Lysol disinfecting wipes at my local supermarket:
Now, I'm not saying that's what's going to happen, but our society has a very thin veneer on top and I've seen it crumble before. And that was for a short-term (two week) hurricane power outage that only affected a small area, but this upper middle-class neighborhood had people stealing generators and gasoline from people's front yards. People on Staten Island were sleeping in their living rooms with shotguns because of looting. For the most part people are behaving right now, but I can easily see many small business folding as they don't make numbers for a month or two. This might only be the beginning of how it affects the economy at large. Additionally, with everyone on edge, the chances for something bad happening that spreads even more fear is high.
Is this the next black plague? No. Should it be taken seriously? I'd say yes. Don't let fear rule your judgement, but don't ignore what's happening, either.
