when every human is a potential treat

the finnish health service has mapped out a terrifing scenario for the bird flu - here - A third of the Finns could catch the virus and about 10,000 could die. hopefully, the scenario is purely a planning exercise and has no use in reality.

but what if such a scenario comes true - God forbid. then every human will become a possible source of infections and human have to minimise or avoid contact with each other. i dont know what kind of a society or economy this will lead to - but i am sure humans will be seggregated based only on one parameter - infected or not - as against caste , creed, religion, skin colour that presently happens.
