Book (series)H5N8 Highly pathogenic avian influenza (HPAI) of Clade 2.3.4.4 detected through surveillance of wild migratory birds in Tyva Republic, Russian Federation – potential for international spread 2016
Also available in:
H5N8 highly pathogenic avian influenza (HPAI) virus of Clade 2.3.4.4 has been detected in migratory birds at Lake Ubsu-Nur in Tyva Republic of the Russian Federation, located on the Central Asian Flyway. Detection of HPAI virus in this location in the past has repeatedly been followed several months later by detection of similar virus in other locations especially to the West and South of Tyva Republic. All countries along this flyway and those to the West in the former Soviet Republics, The Mid dle East, Eastern Europe and even Africa (especially West Africa) should be on the alert for incursions of this virus. -
Book (series)Bluetongue in Europe 2006
Also available in:
No results found.Bluetongue (BT) is a potentially devastating midge-borne disease of ruminants that recently spread across Europe from its traditional tropical endemic areas. Historically, bluetongue virus (BTV) made only brief and rare incursions into fringe areas of Europe, with the Afro-Asian biting midge vector - Culicoides imicola being largely responsible for transmission. Since 1998, however, different strains of BTV entered Europe from at least two directions, and spread up to hundreds of kilometres furt her north than previously reported. Interestingly, the northern range limit of the distribution of C. imicola shifted northward, but other Palearctic Culicoides species, not previously described as potential vectors, may also play a major role in the transmission of BT in Europe. This should be specially the case in south-east of Europe, were C. imicola has never been identified. Very recently, outbreaks were recorded in a transboundary area including Belgium, the Netherlands, Germany and France , far more northern latitudes than the previous limits of the disease. These outbreaks are related to a new serotype previously not reported in Europe. BTV spread in Europe has resulted in massive disruption of trade in animals and animal products and caused the deaths of over 1.5 million sheep. -
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.
