Avian Flu Diary: Detection Of Airborne H9 Nucleic Acid In Chinese Live Poultry Market

In China the link between live poultry markets (LPMs) and the spread (and reassortment of) avian flu strains is already well established, and it is easy to understand why. Large quantities of birds of varying species (chickens, ducks, geese, quail, and others) are brought in from different farms, housed together in cramped quarters, and then slaughtered (and often de-feathered) in open air booths as thousands of people walk by.  Not only does this expose humans to avian viruses, it facilitates the sharing of different avian flu subtypes (H5, H7, H9) among the birds, promoting continual reassortment and the creation of new clades, or subtypes.
