How long would you last?

[NorthernRaider]

A little scenario to consider your own response.
How long would you last?
Lets say an Europe wide health problem comes to pass, perhaps a viral out bacterial disease outbreak that spreads very fast and has a very high mortality rate, Its not airborne just spread by close proximity and via touch etc.
So the government orders everyone to stay at home until the outbreak burns itself out, they estimate two weeks of everyone facing self imposed confinement.
By the end of week one the power supplies fail, not long after the gas and water systems fail, you are in the dark without utilities no gas, electricity, running water or sewage systems.
That means no refrigeration, telephones, waste disposal, elevators, street lights, no central heating etc as well
But after two weeks its still not safe to come out, new cases of infection keep popping up in various places killing anyone infected.
So it turns out that the longer you can remain in isolation ( IE INDOORS in the towns and cities or not venturing outside your gardens if you like in rural areas not close to neighbours)
HOW LONG CAN YOU SUSTAIN YOUR FAMILY remaining in location entirely self sufficient because venturing out risks death from infection or being shop by troops enforcing the lock down?
