I think it happened with SARS too, but that was mostly contained in China. This one happens to be more widespread, so the news is reporting it more than SARS. Plus, with the likes of Instagram, Twitter, and Facebook, more people are sharing their experiences online with their friends, inciting more panic than usual.

But yeah, I suppose hoarding could be mentioned, but with reference to how social media impacts how people think about pandemics/viruses. However, this exact situation happened with H1N1 in downtown Boston when I was living there (bare shelves, etc.), but I don't think that is reported in history books though, unless it was maybe a few lines of text? I know that H1N1 isn't as widespread, but people did behave the same way.
