H7N9

Avian influenza refers to the disease caused by infection with avian (bird) influenza (flu) Type A viruses. http://www.cdc.gov/flu/avianflu/ There are many different strains of bird flu virus, most of which don't infect humans. However, two particular strains have caused serious concern in recent years: H5N1 (since 1997) H7N9 (since 2013) Although these viruses don't infect people easily and aren't usually transmitted from human to human, several people have been infected around the world, leading to a number of deaths. Other bird flu viruses – particularly H7N7 and H9N2, and more recently H6N1, H10N8 and H5N6 – have also infected people, but these have been very rare or only rarely caused severe illness. Bird flu affects many species of birds, including chickens, ducks, turkeys and geese. It can be passed between commercial, wild and pet birds. Birds don't always get sick from infection, so seemingly healthy birds may still pose a risk to people who come into contact with them. http://www.nhs.uk/conditions/Avian-flu/Pages/Introduction.aspx RD
