The number of recovered people still out weighs the number of active cases, and we are still talking about a mere fraction of the global population.
Two clear choices:
1. shut the world down, and wait for it to die out, or 2. carry on as normal.
1 would deliver a brutal short term economic blow, but one that would be recovered from in due course. 2. Would have a more subtle economic impact, but over a longer term. Who's to say which is better 
Ultimately though, if we're all going to catch it regardless, then there's little point in flapping or scaremongering, may as well carry on regardless.
You still have a far higher chance of being hit by a bus.
Ah but are you saying that as a low risk person?. Outside of the hayfever season, i would say we are ultra low risk where we live. However the dice are now loaded much higher with me visiting hospital twice a day to see how the family members are doing etc
Mark is right about the projections. They are just projections.
Stay healthy , exercise and eat your greens....
Not particularly. My work exposes me to aircraft that have almost certainly been carrying passengers to/from an affected regions. Also, if I get it (assuming that I haven't already), even mildly, there's a certainty that I will pass it to
Mother, who will most likely be hospitalised given her 'underlying medical conditions'. She can turn a sniffle into pneumonia, given half a chance, so unfortunately that would probably be a one way journey

Am I concerned? Of course, but neither of us are panicking. Absolutely no point. Que sera, sera.
If anything, I am more likely to be made redundant from an unrelated airline going under than I am to have to take two weeks off from a cold. Which really pisses me off as the only reason that airline is vulnerable is because it is run by greedy, incompetent morons. But I digress...
