Impact of avian influenza in the poultry sectors of five South-East Asian countries

摘要

Highly pathogenic avian influenza (HPAI), in most cases the strain H5N1, was officially reported in 10 east and South-East Asian countries in January 2004. More recent outbreaks of HPAI in July 2005 in poultry and wild birds in Russia, Kazakhstan, Western China and Mongolia have indicated that migratory birds probably act as carriers for HPAI over long distances. The countries most affected have been Vietnam, Cambodia, Laos, Thailand and Indonesia. As part of its response to the crisis, the Animal Production and Health Division of the Food and Agriculture Organization of the United Nations (FAO) implemented a regional project to assist with the post-HP AI rehabilitation. Socioeconomic impact studies were undertaken in each country to identify the effect on poultry producers, especially those most affected, to describe the major poultry production systems affected, and to formulate recommendations for both the short-term recovery and longer-term rehabilitation. FAO and the World Organisation for Animal Health (OIE) have made recommendations for the use of OIE-approved HPAI vaccines that can provide excellent protection and will reduce production losses and mortality. Where vaccination is a national option to protect small-scale poultry farming systems, a community-based approach is useful. This paper presents an across-country synthesis of the data and information generated by the project and the FAO activities.
