This spring, the H7N9 virus(病毒)hit China. This brings the total number of H7N9 cases to 124 in China. So far, 23 people have died. Most of the patients seemed to have the common flu.Other patients had a fever and a cough. They also had trouble breathing. According to the research, people believe the H7N9 virus was from the farm birds sold at markets and birds flying through China. How can you stay away from it? It’s important to wash your hands a lot every day. You must drink boiled water, cook meat and eggs from birds completely. If you are working with farm birds, keep birds away from areas where you eat or sleep. If someone is ill and has a fever and pain in his throat, you must take him to hospital as soon as possible. Luckily, it seems that the H7N9 virus doesn’t spread from man to man.Scientists said: Most people caught it because they had ever been with animals like chickens and ducks.
