Bird flu is a kind of serious disease caused by poultry(家禽). It’s also called H7N9. People that catch this illness may first feel like having a common cold. It was reported that 106 people in China got H7N9 last year and 20 of them died. This year, H7N9 attacked many provinces again, such as Hunan, Fujian, Yunnan, etc. In some places, many markets that sold poultry were closed, and some poultry were even killed, burned and buried(掩埋).
