Consumers bought too much stuff, like toilet papers, during the scare, creating a temporary shortage that forced the retailers to increase the production orders. Now the new goods are piling up while consumers are working through their stash. The piled up goods take up the shelf/warehouse/port space such that other goods are on shortage in arrival. This creates another shortage scare. A vicious cycle.
