How does the swine flu virus survive?

Answer:
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.
