Risk Assessment of the Introduction and Spread of Highly Pathogenic Avian Influenza Viruses (H5-Subtypes) Via Migratory Birds in Iran

Abstract

Background and Objectives: HPAI has economic and public health importance. Aquatic and shore migratory birds are the main reservoirs and the cause of the spread of viruses across countries. The aim of study was risk assessment of the spread of the avian influenza H5 viruses. Methods: In this qualitative study, structured interviews and focus group discussions were used to assess the risk of the introduction and spread of highly pathogenic avian influenza viruses (H5-subtypes) into Iran. Results: Over 300 wetlands, natural and artificial lakes, ponds, and more than 517 bird species (swans, geese, ducks, and coots) are identified in Iran. Weakness in detecting virus entry windows, weakness in passive surveillance of migratory birds, inadequate supervision on hunting of migratory wild birds, movement of hunted birds without any criteria without the control of the Veterinary Organization, inability to monitor the supply of migratory birds in the LBMs, law weaknesses in dealing with offenders, lack of training for people, presence of suitable conditions for close contacts between wild birds and backyard and industrial poultry, and weakness of research on AI in migratory birds were the most important factors influencing the spread of these viruses. Conclusion: HPAI will be one of the most important challenges for the poultry industry and public health. Solving this challenge requires national determination, overhead organizational views, collaborative and practical cooperation of related organizations, and short and long-term planning based on the realities of the country.
