they don't - unless it has divided itself into another cell
viruses are not taken as the living entities.....they are said to be on border line of living and non living and are more accurately accepted as chemical in nature as they can be crystallised unlike living cells......they don't abide by the standards of being living expecting the fact that they replicate in their host cell. thus they can't be said to b surviving outasice host cell....or they need not to survive.
viruses are not alive. APEX
At this time, there is no evidence that prokaryote or eukaryote cells can survive without a cell membrane and be metabolically active at the same time.Many viruses don't have cell membrane but a a protein core instead. Viruses cannot be considered as living cell but infective particles because they are not active outside host cells.
A virus needs a host cell to survive and replicate. Once inside a host cell, the virus can hijack the cell's machinery to make copies of itself. Without a host cell, viruses cannot survive for long periods outside of a living organism.
Viruses need a host cell to survive and reproduce. They cannot replicate on their own; instead, they hijack the machinery of host cells to produce more virus particles. Once they have infected a host cell, they use the cell's resources to replicate their genetic material and assemble new virus particles.
What we need to understand is, viruses do not have its own synthetic machinery such as ribosomes to make proteins. Hence they are completely dependent on the host synthetic machinery for their replication. Virus infects the host cells, integrate its genetic material with the host to produce progeny viral particles.

No, eliminating the supply of oxygen from the air would not kill off a virus because viruses do not require or consume oxygen to survive. Viruses need a living host cell to replicate and cannot survive for long outside of a host organism.

A Virus must invade a host cell in order to reproduce. What people commonly mix up with them is bacteria which has no need to

No, DNA viruses multiply in the host cell's nucleus, while most RNA viruses multiply in the host cell's cytoplasm
Yes, viruses hijack the host cell's machinery to replicate themselves, eventually causing the cell to burst and release new viruses. This process, known as lysis, results in the death of the host cell.
