DESCRIPTION:The brief history and major events of subtypes H9N2 and H5N1 a
 vian influenza in China during 1992-2008 are summarized.  For the control 
 of H5N1 HPAI\, government-subsidized intensive vaccination program and oth
 er control measures including enforced biosecurity of poultry farms\, rest
 riction on the movement of poultry and products\, culling\, quarantine and
  disinfection has been implemented in China since 2004.  In general\, thes
 e strategies are successful in terms of reducing the number of outbreaks\,
  losses from clinical disease and virus load of poultry in endemic areas. 
  On the other hand\, the long term endemicity of H5N1 viruses in poultry p
 opulations in China\, especially in domestic ducks\, constitutes the real 
 threat to public health and agriculture. It has a long way to go for reach
 ing the final goal of H5N1 virus eradication. China produces about two bil
 lion domestic ducks each year\, almost 75% of world total yield.  The auth
 or emphasizes the importance that domestic ducks play in the maintenance a
 nd evolution of H5N1 avian influenza viruses.
