I am assuming that you are asking how a virus lives in the body.
A virus is NOT a live organism. It is able to penetrate the host's cells and duplicate the RNA/DNA within those cells and when those cells replicate, the virus also replicates, thus growing in numbers very quickly.
Viruses are difficult to kill since they are not considered living organisms. One way that might help is to denature the proteins that are living inside the cytoplasm of the virus.
Shingles are caused by the varicella virus, the same virus that causes chicken pox. Those who have had chicken pox when younger carry the dormant virus for the rest of their lives. Should the virus "reactivate" in an adult, the result is shingles.
It is called a host cell. The virus attaches to the cell and injects its DNA into the cell. The virus's DNA overruns the "instructions" that the cell has and "tells" the cell to make copies of the virus using the DNA. Then the cell makes so many copies of the virus, that it explodes. The new viruses then go on to attach to other cells.
The scientific word for virus is "virus."
A virus is a small infectious agent that can only replicate inside the living cells of an organism. A host is an organism that provides nourishment and a habitat for another organism. A parasite is an organism that lives on or inside another organism (the host) and benefits at the host's expense.
The singular of virus is "virus." Unlike most words, virus does not change form when it is singular or plural.
That depends on the bacteria, the virus, and your definition of "living."
A virus will replicate within a host cell.
Its a virus - IF it lives at all it lives in cells.

Hepatitis A.
No. HIV is not a virus that lives in dogs.
A host.
A parasite is any organism that lives on or in another organism, not necessarily a fungus, virus or bacteria.
A virus or parasite that lives within an organism lacking a nucleus could infect a prokaryotic cell, such as a bacterium. In this case, the virus or parasite would utilize the host's cellular machinery to replicate and survive without the presence of a nucleus.
a tapeworm is neither, it is a living organism which lives in the intestine. but if any, it COULD be classed as a virus.
