Not long: Viruses require living cells in which to propagate in order to remain viable. As soon as they are expelled as free virus they will not last long against environmental conditions. If living cells containing virus are excreted, they too will not survive very long. This is one of the reasons that there is seldom if ever transmission of these agents by inanimate objects.
