The first cases of the deadly H5N1 have been confirmed in 1 where most efforts focus on trying to keep domestic birds away from wild 2 birds and 3 birds. In the Danube delta, thousands of 4, 5 and 6 have already been slaughtered. 7 of birds, experts say, create a perfect environment for spreading disease. In the second confirmed bird-flu cluster in the delta, 8 swans have died on a fish farm. In the third cluster, 9 swans have died so far. But this is the 10 of the avian influenza iceberg. Bird flu is believed to present in Romania, 11, 12, and 13 because white-fronted geese can travel 14 kilometres in a single day! All expeditions to the delta have been banned and not a domestic bird in sight. They've all been gathered, 15, and buried. According to WHO, the 16 will remain for a long time in the region. The more cases to be 17, the more quarantine 18 will have to be launched, with 19 killed, people closely 20, and areas sealed off. No one can say how this story will end.
