Book (series)Potential risk of Highly Pathogenic Avian Influenza (HPAI) spreading through wild water bird migration
Updated version
2005Also available in:
No results found.There is a potential that Highly Pathogenic Avian Influenza (HPAI) subtype H5N1 might be carried along migration routes of wild water birds to densely populated areas in the south Asian subcontinent and along migratory flyways to Europe. Recent outbreaks of HPAI in Russia and Kazakhstan (August, 2005) attest to this fact. Looking at the major bird migration routes (Fig. 1), the HPAI H5N1 virus could possibly spread from Siberia to the Caspian and Black Sea areas in the foreseeable future. Some w ild water birds are nesting in the newly AI affected areas in Novosibirsk and Altai in Russia and will migrate to the above-mentioned areas for winter or stop-over on their way to Africa and Europe. Bird migration routes run across Azerbaijan, Iran, Iraq, Georgia, Ukraine and some Mediterranean countries, where bird flu outbreaks are a possibility. Also India and Bangladesh, which currently seem to be uninfected, are at risk because both areas harbour large numbers of domestic duck and the count ries are situated along one of the major migratory routes. They have the potential to become new large endemic foci of HPAI infection. Additionally, spring migration of 2006 may result in the spread of HPAI H5N1 virus across European Russia, because birds migrating from Europe and European Russia and Siberia have common wintering areas in Southwest Asia. -
Book (series)Avian influenza spread into Europe
Situation update (July - October 2005)
2005Also available in:
No results found.The likely progressive spread of highly pathogenic avian influenza (HPAI) into new regions will require proactive intervention by the countries at risk, especially those situated along wild bird migration routes. Increased surveillance, detection capabilities and emergency preparedness will be required. Public awareness, along with education and training of veterinary and veterinary para-professionals, farmers, marketers, and poultry transport contractors and egg collectors, will be required to ensure that the disease is either prevented or detected and controlled, in order to prevent its establishment and maintenance in newly colonized ecosystems. -
Book (stand-alone)Potential spread of highly pathogenic avian influenza H5N1 by wildfowl
dispersal ranges and rates determined from large-scale satellite telemetry
2010Also available in:
No results found.Migratory birds are major candidates for long-distance dispersal of zoonotic pathogens. In recent years, wildfowl have been suspected of contributing to the rapid geographic spread of the highly pathogenic avian influenza (HPAI) H5N1 virus. Experimental infection studies reveal that some wild ducks, geese and swans shed this virus asymptomatically and hence have the potential to spread it as they move…
