我们常常说的感冒90%以上是由病毒所致,其中鼻病毒、冠状病毒占60%,还有副流感病毒、呼吸道合胞病毒、腺病毒、柯萨奇病毒、埃可病毒等;而流行性感冒(简称流感)是由流感病毒引起的急性呼吸道传染病。从病原角度来看,大多数感冒和流感可以不用抗生素,因为抗生素对于这些病毒没有任何作用。有多项严格的临床试验表明,抗生素治疗感冒不能缩短病程和改善预后,也不能预防感冒的细菌并发症。 We often say that more than 90% of the flu is caused by the virus, of which 46% are rhinovirus and coronavirus, and also have parainfluenza virus, respiratory syncytial virus, adenovirus, coxsackie virus and echovirus; The flu (flu) is an acute respiratory infection caused by the flu virus. From a pathogenic point of view, most common cold and flu do not have antibiotics because antibiotics have no effect on these viruses. A number of rigorous clinical trials have shown that antibiotics for the treatment of colds can not shorten the course and improve the prognosis, nor can they prevent the bacterial complications of cold.
