GUIDING PRINCIPLES FOR HIGHLY PATHOGENIC AVIAN INFLUENZA SURVEILLANCE AND DIAGNOSTIC NETWORKS IN ASIA Page 1FAO EXPERT MEETING ON SURVEILLANCE AND DIAGNOSIS OF AVIAN INFLUENZA IN ASIA BANGKOK 2123 JULY 2004 GUIDING PRINCIPLES FOR HIGHLY PATHOGENIC AVIAN INFLUENZA SURVEILLANCE AND DIAGNOSTIC NETWORKS IN ASIA 1. INTRODUCTION 1.1 Purpose The purpose of this document is to provide guiding principles and minimum requirements for surveillance and diagnosis of H5N1 highly pathogenic avian influenza (HPAI) that can be applied by countries and regional networks. These principles and minimum requirements are also broadly applicable to other avian influenza (AI) viruses. These guidelines may not be directly applicable to surveillance for low pathogenicity AI (LPAI) viruses. Recommendations of the Office International des Epizooties (OIE which is the world organization for animal health) ca recommendations on LPAI should be read in conjunction with this document. The control of H5N1 HPAI in Asia requires an understanding of the behaviour and ecology of influenza viruses generally and of this subtype in particular. It is also important to understand local poultry production and marketing systems and how these affect the development and course of HPAI. Without a proper understanding of these factors attempts to control or eradicate the disease will fail. Much of the current understanding of AI (and the recommendations of international organizations) is based on information from temperate climates such as Europe and North America. Although there is much that is useful and applicable in this information poultry production systems differ significantly in Asia and these differences must be taken into account in designing and implementing surveillance and diagnostic systems. Although effective surveillance and diagnosis are critical to the control of HPAI other important measures include: Rapid humane destruction of infected poultry and poultry at high risk of infection.
