引起感冒的病毒种类很多,但最常见者为鼻病毒,成人感冒1/3以上由鼻病毒引起。感冒怎样传播,所知甚少。咳嗽及喷嚏固可以传播疾病,但能否传播感冒值得怀疑。既往的资料不支持感冒系由空气传播。实验证明:鼻病毒不能经过空气造成人与人之间的传染,易感者与排病毒者以金属丝网相隔,即不能造成传染,而柯萨奇A-21型病毒则可通过此种屏障。另一实验证明:鼻病毒排毒者唱歌与大声高谈,并不能使同在一密闭室内的易感者发 A wide range of viruses cause a cold, but the most common is rhinovirus, adult influenza caused by more than one third of the rhinovirus. How to spread a cold, little is known. Cough and sneeze can spread the disease, but it is doubtful whether the cold can be transmitted. Past data do not support the cold is spread by the air. Experiments show that: rhinovirus can not cause airborne infection between people, susceptible and virus-negative persons separated by a metal mesh, that can not cause infection, and Coxsackie A-21 virus can pass this barrier . Another experiment shows that: rhinovirus detoxification sing and talk loudly, and can not make the same susceptible person in an airtight room
