Yesterday, we read article about bird flu. We had to go onto a article about Bird Flu and there was words highlighted in green. We had to find the places that were highlighted in green on the map and circle them. Here is what I mean. The current strain is descended from the H5N1 virus, which started killing poultry in China in 1996, and then people too. H5N1 exploded across east Asia in 2004 with the poultry trade, and then spread into Europe and Africa in 2006, thanks to migrating birds. Since then, the virus has lurked mainly in poultry, especially flu-vaccinated chickens in Asia that can carry the virus while being immune to it. So far, 452 people have died after catching it from poultry.
But viruses like H5N1 have also been moving with migrating dabbling ducks like mallards, which are usually immune to it. Birds from all over Eurasia mingle in north-central Asia during the summer, swap viruses, then disperse back to Africa, Asia and Europe for the winter.
Hope you like my work!
