The Water Deer (Hydropotes inermis) is a usually solitary animal, besides the rutting months, and a good swimmer. There exist two subspecies: the Chinese Water Deer (Hydropotes inermis inermis) and the Korean Water Deer (Hydropotes inermis argyropus).
Viruses lack most of the internal structure and machinery which characterize 'life', including the biosynthetic machinery that is necessary for reproduction. In order for a virus to replicate it must infect a suitable host cell.
I would argue that a virus is not alive. Viruses are completely dependent on host cells to replicate. That said, in absence of the host cell the virus clearly lacks most of the properties of a living thing. would argue that a virus is not alive.
