Synopsis (short abstract) 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.

    Following the introduction of H5N1 HPAI into Turkey in October 2005, the disease has been reported (as of August 2006) in poultry or wild birds in 26 European countries. From October 2005 onwards, outbreaks of HPAI in domestic poultry have been reported in Albania, Austria, Azerbaijan, Denmark, France, Germany, Hungary, Romania, Russian Federation, Serbia, Turkey and Ukraine, with over 230 recorded outbreaks in Romania alone. With the exception of Albania, all countries also detected HPAI in wil d birds. Thirteen countries reported HPAI in wild birds only (Bosnia-Herzegovina, Bulgaria, Croatia, Czech Republic, Georgia, Greece, Italy, Poland, Slovakia, Spain, Slovenia, Switzerland, United Kingdom). HPAI was also reported in mammals (cats, dogs, and stone marten) and captive wild birds (game and zoo birds).
