The Hong Kong Center for Health Protection reported two cases of H9N2 avian influenza in infants.  The cases were diagnosed in Guizhou and Guangxi Provinces in late October and early November respectively.

According to the ProMED posting H9N2 is prevalent in poultry raised in both provinces and is accepted as a zoonotic infection.  The route of exposure involves sale of chickens and ducks in live bird markets in both urban and rural areas. Authorities have promoted or mandated H9N2 vaccine for poultry in many areas to suppress infection and reduce infection of human contacts.

It is noted that China documents avian influenza in human contacts and in wild birds but apparently by some miraculous mechanism does not encounter avian influenza in commercial flocks. Accordingly there are no reports of either H5 or H7 outbreaks to WOAH.
