The influenza viruses, like Swine Flu (H1N1/09), reproduce in a method called the lytic cycle.
As a quick and over-simplified explanation of the lytic cycle: the virus attaches to your cell (flu viruses attach to the cells of mucous tissue, mostly first in the nose, mouth and eyes), inserts its DNA/RNA into the cell and that instructs the cell to stop what it was doing as its normal function for the body and start making replications of the virus instead. In that way, the virus, a non-living organism, hijacks our bodies to supply the raw materials and do the work required to reproduce itself. Once that one cell makes a full batch of virus particles, the cell splits open and the "newbie" virus particles go attach to other cells and repeat the cycle entering cell after cell after cell. The hijacking and death of the split open cells help trigger our bodies to begin the attack on the virus. It is then that we will feel the symptoms of both the loss of the cells from their regular duties, and the immune response that includes the fever, excess mucus production, etc.
See the related questions below for more detailed information about the lytic cycle.

What is the Swine Flu reproductive cycle?
Swine flu is a virus and viruses reproduce by injecting it's own DNA into a host cell and then that cell is corrupted and taken over and becomes a flu cell. =]
How does the Swine Flu virus survive?
The swine flu H1N1/09 virus survives as do all viruses, by invading a host to support it and do its work to reproduce. Viruses can not live without a host to infect. That is why some viral diseases have been eliminated by vaccination programs, if everyone is vaccinated, no one becomes a host. Don't let flu viruses survive inside you, get a flu vaccination every year prior to flu season.
How does the flu reproduce and survive in the human body?
To continue to replicate and exist, a flu virus must be in a host animal's cells. They can be grown in cultures (and eggs) for creating vaccines, but need a living host for long term activity and to "live".
What is the energy source of the flu virus?
The flu virus is a non-living thing, so it doesn't have its own energy source. To reproduce, it hijacks the cells of a living being, such as the upper respiratory cells of a human, and uses the energy of those cells to make more copies of itself.
Why Every year a new influenza vaccine is developed What is the most likely reason that doctors do not use the same vaccine each year?
Typically the flu vaccine is trying to predict the possible states of the flu coming for that season. The flu virus mutates so rapidly that they are always trying to predict what's coming next. That's why you can also still get the flu even if you get a flu shot. STUDY ISLAND ANSWER:The virus which causes influenza adapts each year to the last vaccine in order to survive and reproduce.
What type of symbiosis is H1N1?
H1N1/09 Swine Flu is caused by a virus. Viruses invade a host to reproduce. Since the invasion is only beneficial for the virus and detrimental to the host, it is more an example of parasitic than symbiotic relationships. The Turkish name for swine flu is " Domuz Gribi". "Pink ill"
Are the flu and Swine Flu the same?
No, Swine Flu is just one strain of the many flu viruses. Flu is an abbreviation for influenza. So Swine Flu is a type of flu, but all flu is not the swine flu, there are other kinds.
A microscopic particle that invades a cell and often destoys it?
The answer to this question is a virus!a virus is what causes you to get a flu and other sicknesses. Remember, a virus is NOT A LIVING ORGANISM! There for, it needs a host cell to reproduce and get nutrients.
What types of flu create the Swine Flu?
A mixture of the standard Human Flu, Bird Flu and Pig Flu. This creates a new strain of flu called swine flu (Influenza A H1 N1).
Is Swine Flu an organism?
Yes, Swine flu is caused by a microscopic organism, a virus. The same type of microorganism also causes the common cold, Viral "stomach flu" (gastroenteritis), and the seasonal flu that comes around each year, plus many others. Viruses aren't really alive like bacteria and other types of microorganisms, but it acts alive since it can reproduce by using genetic material from the host animal's cells. See the related question below for information on the different types of microorgansims (microbes).
Is the Swine Flu the same as the tami flu?
Swine flu is a flu very similar to the regular flu. Tamiflu is a medicine that you take when you have swine flu or other types of influenza.
Which has worst side effects the flu or the flu vaccine?
The flu. One of the side affects of flu can be death.
