WHO: Evolution of H5N1 avian influenza virus does not increase risk to public health

The WHO Global Influenza Surveillance and Response System, the group of experts that studies animal and human influenza viruses that may impact human health, recognized this new clade in February 2011.
WHO also routinely assesses the public health risk from all animal influenza viruses. Based on available information, the identification of this newly-reported H5N1 virus clade does not change the current public health implications of the H5N1 avian influenza viruses for humans. Human cases of H5N1 infection remain rare and sporadic events, occurring mostly in areas where H5N1 viruses circulate regularly in poultry. Human cases could occur wherever the viruses are present in poultry and when humans might be exposed to infected birds or contaminated environments.
