流行性感冒又简称流感。它是由一种滤过性病毒所引超而具有高度传染性的急性传染病。引起流行性感冒的流感病毒,用一般显微镜不能看见它,只有在电子显微镜下可以看见。流感病毒对于外界环境的抵抗力弱,在室温的环境中,只能生存几小时;在直射目光下或加温60℃时经5—10分钟就可死亡;同时它对消毒剂亦很敏感,在0.1%石炭酸溶液中能活一个月,在5%的石炭酸溶液中很快就死亡。但抗生素对它没有作用。相反地流感病毒在干燥真空的环境中,在0°—4℃的冰箱中可以保存很多年。
Flu also referred to as flu. It is a highly contagious acute infectious disease caused by a viral virus. Flu virus that causes influenza, can not see it with a normal microscope, only visible under the electron microscope. Influenza virus for the external environment weak resistance, in the environment at room temperature, can only survive a few hours; in direct sunlight or warming 60 ℃ by 5-10 minutes can die; at the same time it is also very sensitive to disinfectants, In 0.1% carbolic acid solution to live a month, in 5% carbolic acid solution soon died. But antibiotics have no effect on it. In contrast, influenza viruses can be stored in refrigerators at 0 ° -4 ° C for many years in a dry, vacuum environment.
