If everyone was required to stay at home for 2 months with zero contact with other people could we wipe out the cold/flu forever?

Or can it come from somewhere else somehow?

Not a chance, the biological world consists of a lot more than just humans, influenza in this case infects a wide variety of animals, hence the "swine" or "bird" flu you hear about. Also a lot of diseases can have incubation times or even be dormant for decades like in the case of TB.
