Hi Frank2135,

I think those PSAs suggesting 2 weeks supply of food and water should be revised. The UK National Health Service (NHS) ran a study on this scenario. From their results the timescales should be nearer 2-3 months self quarantine, with the high probability of a second round of infection within 6 months again lasting 2-3 months. A quarter of the population was projected to become infected with the pandemic flu.
