H1N1 is the very clinical-sounding official name for Swine Flu (so named because the virus is very similar to one carried by pigs). It is a flu virus and it spreads in the same way as seasonal flu: through direct contact with people who are already infected, through airborne cough and sneeze germs, and by sharing drinks and cutlery.
