Firstly the Covid 19 Corona Virus is respiratory and not gastrointestinal. Unless you want enough TP to wrap your Christmas presents for the next 10 years quit buying and hording it. BTW reliable sources tell me that most of the TP we consume is manufactured in Quebec not China. Irresponsible tv media and of course Facebook and other social media have created panic and doomsday thinking. Remember that most social media in today's world is crap at providing correct information and terrific at providing anonymity for someone behind a keyboard!
My take on the whole thing? Don't travel, at least commercially, stay away from crowds, (Costco) and wash your friggin' hands 20 times or more a day. A good friend who is knowledgeable tells me that although the virus enters the body through the nose and mouth, most dies on its way to the stomach. It also enters the body through the eyes and ears!
Stop toughing your eyes, ears, nose and mouth and WASH YOUR HANDS frequently.
