Vincent Racaniello – who is a Professor of Microbiology at Columbia University Medical Center - gives us a virology lesson today on the much discussed H1N1 mutations announced in Norway last week.
He argues that the change – an amino acid substitution (D225G) –impairs the `fitness’ of the virus to transmit to other hosts, and therefore isn’t as big of threat as some have suggested.
Since I am woefully out of my league here (despite listening to his excellent podcasts each week on TWiV), I’ll simply step aside and direct you to his informative blog entry.
The D225G change in 2009 H1N1 influenza virus is not a concern
