If you are asking if a virus can live very long without its host, then no. Viruses aren't alive in the first place. Because viruses can't reproduce on their own, they are not considered living organisms. Because they aren't living to begin with, they cannot die.
Without a host an influenza virsu cannot survive.
A lytic virus begins to multiply right away. A lysogenic virus can "hide" for a very long time before multiplying. See link below:
It depends on the virus. Viruses may have a very specific host range.
A virus is technically classified as a non living entity. It can only survive and proliferate upon contact with its host. A virus is an obligate parasite - meaning it cannot survive in the absence of its host. I virus is composed of a smaller genome than a bacteria and has specific and limited functions. Bacteria on the other hand have organelles and other sub cellular structures in their cytoplasm. Certain bacteria are infections to humans. The mode of attack is very different for bacteria and viruses. While bacteria generally release toxins into the body, viruses invade cells, replicate within them and destroy the host genome resulting in cell death
It uses the energy of a host cell, in a sort of parasitic way. A virus is non-living, although it is a well structured organism able to reproduce and cause things to happen. To do these things, it does not generate or use its own power or energy. Instead, it invades a living host (a plant, animal or human) and attaches a virus particle into a cell and makes that living cell of the host to which it has attached change its operations from working for the host to working for the virus. The cell begins to create duplicates of the virus particles. It does this because once the virus has attached itself, it adds part of its own DNA or RNA instructions into the cell which turns the cell into a virus-making factory. The cell's original DNA is no longer giving the instructions to the cell and so it is no longer doing what it is supposed to for the host and eventually dies when it bursts open to release the virus "babies". This is what makes us get sick if enough of our cells are pulled off their usual jobs by the virus and made to do other things and then die. All the energy that is needed to reproduce the virus is supplied by the host cell, and as it produces new virus particles those "offspring" attach to more cells and the process repeats cell by cell particle by particle as it moves through our bodies and attaches to more cells. Eventually (hopefully) our body's immune system learns the key to turning the virus off (or "killing" it). If too many of our cells are diverted before the immune system figures out how to attack the virus to stop it, then we can have organ and system failures and that is how we get very ill or even die.
Mutations are very common in all organisms. There are various mechanisms of repair in most cellular organisms that detect and correct these mutations both as they occur and afterwards. Viruses are very simple organisms and contain very few proteins. Repair mechanisms are limited to the simplest mechanisms of the host cell. Since much fewer of the mutations are repaired, it is easy for a mutation to become permanently incorporated into a virus genome. Viruses also frequently use single stranded DNA or RNA, in which case mutations are much harder to detect, even for the simple repair mechanisms that may take place during the host cell's replication processes.
A very simple answer is lysogenic virus. it could still kill the cell eventually if it becomes lytic.
A lytic virus begins to multiply right away. A lysogenic virus can "hide" for a very long time before multiplying. See link below:
The virus just infects the host cell but remains quiet for a long time. Something may cause it to become active again. A very good example of this is the chickenpox virus. It can remain for a long time in the hosts' nervous system and something will reactivate it. It is then called shingles.
No, because for a virus to reproduce, it needs a cell to take energy and stuff from. When the cell is dead it moves on to another cell. It short, it is very hard for a virus to reproduce or multiply, without a host (e.g. a red blood cell).
It depends on the virus. Viruses may have a very specific host range.
There is no such thing. viruses are so very small that a living thing could not live inside one. But a virus inside a living thing could be called latent if it is not causing a disease or active if it is.
A very long time.

It has to enter the host DNA and "make" the host DNA make the virus parts. To do this the RNA that the virus contains has to be able to enter into the cell nucleus and take over the host DNA. It carries an enzyme called reverse transcriptase to complete this. See the link below for a very good idea of how it works:
No. Viruses are very basic and that is why they require a host to live and multiply. A virus consists of nucleic acid and a capsid.
a very long time you have to be lucky
The time it takes a virus to mutate varies depending on the virus. However, viruses mutate frequently so it is very difficult to completely eradicate a virus.
