What are the four phases of Swine Flu?

Answer 1

It is not a combination of four viruses in Swine Flu, only the one H1N1/09 virus.

You may be thinking of the four types of genetic material contained in the genome (virus DNA or RNA hereditary information) that are found in the H1N1/09 virus. These contain the genetic material of the virus and help in identification of the specific virus and the origins of it.

Swine flu (H1N1/09) contains genomes from four types of flu, this is called a quadruple reassortant (or reassortment). It indicates that there have been changes in the original virus with introduction of new genomes to create the new form. The four types of flu reassorted in the pandemic swine flu are: Eurasian swine flu, American swine flu, Avian flu, and Human flu.

Some scientists prefer to call it a quintuple reassortant and list it as five by breaking down Eurasian swine flu into the original two genomes that combined to form it, Asian swine flu and European swine flu.
