This thing is going to last months. Containment is going to fail to a large degree. except for those following extreme protocols. You should have already have thought forward and planned for what to do when your household becomes infected. I have little doubt mine will.
Its been known well for weeks that pneumonia is a likely outcome for severe cases. Its been known that there is going to be a shortage of antibiotics and critical meds being held hostage by China. You should have already planned for that. It has been forecasted that hospitals and ICU capacity will be overrun, leaving many unable to get things like oxygen therapy. So why are you still so focused on food? That should have been taken care of long ago.
You need to be thinking through all of the worst case scenarios, add your assessment of reality, and how fast things can advance (hint: we are entering exponential growth phase), and try to stay ahead of the masses. Worst Cases: One week and most businesses will have cut way back and you need to work from home if possible. Two weeks and the supply chain is wiped out, cases have skyrocketed and most non-essential businesses could be closed. Layoffs accelerate and no income for hourly workers. Three weeks and nobody is going anywhere without being fully suited up, and medical facilities will be overwhelmed. Market is at 50% of its highs. Bank holiday anyone? Brown outs? How well have you planned?
