Fears UK could face bird flu outbreak even WORSE than 2009 swine flu pandemic
Earlier this year thousands of chickens were set to be culled after a bird flu outbreak was confirmed in East Anglia. The bird flu virus has only been caught by humans from birds, or close family members who became infected. In 1918 a bird flu strain killed up to 100million people all over the world. Bird flu is an infectious virus which affects many species of birds and certain strains can pose a threat to humans. "These precautions include avoiding visiting live animal markets and poultry farms and avoiding contact with animal waste or untreated bird feathers.The H7N9 bird Flu virus has influenza scientists on edge, due to an unexpected surge of human infections — hundreds of cases — caused by the virus this spring. Bird flu viruses don't spread easily from ferret to ferret; if a modified H7N9 virus did, that would suggest it might do the same in people. Flu viruses attach to receptors found on the cells of their intended victims. Fouchier, who has done work trying to see how H5N1 bird flu viruses could adapt to infect people, was not involved in this study. Bird flu viruses attach to one type of receptor.
