摘要

Avian influenza viruses have been first known to jump the interspecies barrier and cause human infections since 1959 [1].However,avian influenza was not considered a serious threat to public health until 1997,when the influenza A(H5N1) virus caused an outbreak in Hong Kong with 18 cases including six deaths [2].The A(H5N1) epidemic has never stopped despite poultry immunization,and just between 2003 and 2013,A(H5N1) has led to 641 cases and 380 deaths [3,4].Before 2013,the only other avian influenza virus that has caused large-scale human outbreaks was the A(H7N7) virus,which led to 89 cases in the Netherlands in 2003 [5].
