People were buying things to keep stocks that is why everything was cleared now even I did witnessed the same things on many super market.People thinks that the complete world might get shut down like zombie moves like Resident evil so they need things like this to survive for few days,weeks or months? 
Well if they start getting quarantined as in China that is the wise thing to do (in theory people should always have plenty of non-perishable supplies just in case for any other catastrophe).
The Zombie shows often depict a virus going lose so that part is right...
At least you guys are now starting too feel how it is under a socialist economy, just imagine that scarcity didn't last a few days or weeks, but years instead...
