Avian influenza, or bird flu as it is more commonly known, was discovered over a century ago in Italy and to date, there are several strains of the bird flu virus. Many of these strains have become deadly, particularly the H5 and H7 strains. The deadliest one to date, the H5N1 strain, has reportedly killed 70 people in Asia alone in the last two years.
