How do people become infected with influenza A(H1N1)?
  
人是怎样感染甲型H1N1流感的？

Outbreaks in humans are now occurring from human-to-human transmission. When infected people cough or sneeze, infected droplets get on their hands, drop onto surfaces, or are dispersed into the air. Another person can breathe in contaminated air, or touch infected hands or surfaces, and be exposed. To prevent spread, people should cover their mouth and nose with a tissue when coughing, and wash their hands regularly.
  
人类疫情现在是人际传播。感染者咳嗽或打喷嚏时，飞沫会沾到手上和物体表面，或散播到空气中。另一人则可能吸入污染空气，或触摸受感染的手或物体表面，并有暴露风险。为避免传播疾病，人们咳嗽时应用纸巾掩盖口鼻，并且应当勤洗手。
