You can’t. But it can be made less risky, as Italy is requiring. Maintaining social distance when shopping for food or at a pharmacy. And I understand those who cannot work from home are going to work in Italy. The goal is minimize contact with others. Once people stop panic buying (if they do?) food supply should not be an issue. Not sure about toilet paper. I am limiting my panic buying to dog food and liquor. I wonder if liquor stores will be considered “essential” or “food service” when the broad shut down is in place. Seems like they should be.
It scary, because of president* shit-for-brains assmouth and his stupid sycophants, but we are all in this together and we will help each other in spite of the void in leadership. I know it’s harder for those with kiddos or other dependents but we can do it, dammit.
