Hi,
I am not a medic, but as far as I know cholera and typhus are not 
viral infections (bacteria and protozoa).  I am not sure about listeria.
Crucial details, if you catch one of these bugs, because their 
treatment in our part of the world is no big problem.  
But many viruses can be spread by water, just thinking of  
menengitis or polio (?).  Viral infections are much harder to cure 
than bacterial infections (like cold vs. flu).
I am think most viruses are to small to be filtered, so additional 
chemical treatment would be necessary to inactivate them.  Some 
filters offer this additional step.
