Good question: Because a virus is DNA or RNA, I used to think that a virus could not survive at all outside a cell. In reviewing the literature a while ago, I found to my surprise that some viruses can remain for days or weeks on inanimate objects and in water or sewage for very long periods of time. So it depends on the virus but they can survive outside the body for days to months.
