Hi Martin, maybe interesting too: The actual outbreak in Al-Khari (Saudi Arabia). Location is 150 Km south of Riyadh. My investigations shows that it must be the AL-KHMEES SONS COMPANY Po Box 6929 11942 Al Kharj Saudi Arabia Poultry Company. Infected species: Chicken (not clar yet if broiler or egg-industry). First official statements (like in GB): "Wild- or migratory birds" as "most likely explaination". But there are neither wild nor migratory birds. Google maps sattelite photos shows only desert in this area.

Re outbreaks in GB: There are some interesting movies on youtube.com (especially "Biosecurity" related) : Christmas Turkeys Infected With Deadly Virus http://www.youtube.com/watch?v=-h6yx8xgd8E (will send you some pictures by mail in addition) Another topic: What the hell das this News fom bangladesh means: 

[.. And though a permanent relationship between migratory birds and bird flu has yet to be proven beyond a doubt, according to the World Health Organization (WHO), "scientists are increasingly convinced that some migratory waterfowl are now carrying the H5N1 virus in its highly pathogenic form, sometimes over long distances, and introducing the virus to poultry flocks in areas that lie along their migratory routes" – all of which worries health officials in Bangladesh. ..] All the best, Werner
