There definitely is. According to published reports I saw a week or two ago from Japan, one jackwagon on social media over there claimed that masks were made from the same material as toilet paper (manifestly not true), so, he claimed, since there was a shortage of masks, TP shortages had to be next (again: not true). Of course, it didn't take long for people to take once glimpse at that idea, and start to panic. Stores were swarmed with folks buying every roll they could, and guess what? Now there's a "shortage." Not a shortage based on actual need or increased use, but instead on nothing more than gullibility, poor critical thinking skills, and dumb, mindless panic.
I'm not sure what the root cause of it is in the US, but it's every bit as ridiculous. People have no concept of how the timing of supply chains work, apparently. They also seem to think that if - IF - they simply have to stay at home for a couple of weeks, the entire rest of the world will instantly vanish somehow, leaving them utterly stranded and helpless. Apparently, they don't think there will be any such thing as grocery delivery services, or even nearby family, friends, neighbors, etc. who could likely be called upon to do some shopping for them, and drop some things off.
The ridiculousness is ramping up, too. I've seen some sources "recommending" stocking up on supplies like dry goods, canned foods, and drinkable water, as if this virus is going to somehow shut down power grids and water utilities (it won't). It's not a hurricane; Even if folks have to stay home, one can still cook anything and everything you'd have normally. Have all the beer and pizza you want, and watch TV. It won't be that hard. Or rather, it shouldn't have to be, if people would just pause and think things through.
Basically, we're seeing the result of another plague: The death of common sense and a basic understanding of how things work.
