Is it possible that transmission is occurring but not being detected because of reduced virulence in some genetic backgounds?
This paper by the Kawaoka group is the first report of an H5N1 virus that is transmissible by aerosol between mammals.
This is the H5N1 mammal transmissibility paper from the Fouchier group.
Is it possible that transmission is occurring but not being detected because of reduced virulence in some genetic backgounds?
This is the modeling paper co-authored by the Kawaoka, Fouchier and Smith groups that attempts to model the likelihood that an H5N1 influenza capable of transmission will emerge in nature.
This issue of mBio has several updates and opinion pieces on the H5N1 research moratorium.
