Swine influenza is probably the most famous zoonotic influenza. It is an infection caused by any one of several types of swine influenza viruses. As of 2009, the known SIV strains include influenza C and the subtypes of influenza A known as H1N1, H1N2, H2N1, H3N1, H3N2, and H2N3. These are relatively new strains of an influenza virus that causes symptoms similar to the regular flu.

Swine flu made headlines in 2009 when it was first discovered in humans and became a pandemic.
