activities of reference laboratories & collaborating centres:The Role of Vaccines and Vaccination in Avian Influenza Control and Eradication

摘要

High pathogenicity avian influenza (HPAI)and low pathogenicity notifiable avian influenza (LPNAI) in poultry are reportable to the World Organisation for Animal Health (OIE) by its Member Countries. Twenty-nine distinct epizootics of HPAI have occurred since 1959, with the H5N1 HPAI panzootic in Asia, Africa and Eastern Europe being the largest, affecting poultry and/or wild birds in 63 countries. The first case occurred in 1996 in the People’s Republic of China, with the start of global spread in 2003. Historically, stamping-out was used to achieve eradication in 24 epizootics, while vaccination was used in four epizootics as an adjunct to stamping-out.
