The Swine Is Safe Again!

Dear piggy,

The CDC cleared your name today stating that there is NO connection between this latest strain of Influenza and contact with swine. It is now being called H1N1 as it was in 1976.

So, the question now is “Who named this flu in the first place?” According to www.haverford.edu, it is due to the fact that scientists believe that the strain is from the recombination of influenza viruses from different sources, such as from a human and from a swine.

They also go on to say,”The influenza virus is relatively unique in its ability to change its H and N molecules, called antigenic shift. For example, the swine flu of 1918 was named H1N1, while a later strain of influenza which was found to have changed its hemagglutinin molecules was named H2N1, and an even later influenza was found to have changed both its surface molecules (double antigenic shift), and was named H2N2″.
