Subject: How long can a calicivirus or rotavirus remain infective on a fomite?

Many of my patients ask me how long common items in their home are 
infective if a sick person touches them.  These items would be things such 
as doorknobs or telephones in a common household situation.  Room temp of 
about 75F and not too humid or dry.  Sometimes these items can't be 
sprayed with a disinfectant and they want to know how long to avoid 
touching them.  I, unfortunately can't answer them.
