I wouldn't call it no big deal. However, the circumstances today are totally different than they were in 1918. There was no thinking of quarantening people -rather they did the opposite: hundreds of thousands of soldies were shipped around all over the world. In addition, so many people lived in appalling conditions, like the soldier in the muddy trenches and civilians being malnourished. And the strongest medicine they had was Camomile tea with honey.
What worries me on this current virus is, how it is battled by the Chinese. If they keep their industrial production closed for a while, it will have devastating effects on the economy all over the world. Already now some car manufacturers in Europe had to stop production lines, because parts needed are not being send from China any longer. And that will rapidly spread and get worse, if things don't go back to normal in China soon.
This could lead to the big economical and financial crash, that some people have forecast. This virus could be the "black swan" event that triggers the economical big bang, and only God know what the consequences could be.
