医生在诊病时,经常会告诫病人:“单纯患感冒,不必服用抗生素,抗生素对病毒感染无效。”是的,许多人都知道抗生素有抑制细菌生长和杀死细菌的作用。但抗生素为什么对同样是病原体的病毒又显得无能为力呢?关于这一点,恐怕有些人是不太了解的。要回答这个问题,首先要弄清病毒究竟与细菌有什么不同。 When a doctor visits a doctor, he often tells the patient: “A simple cold, no need to take antibiotics, antibiotics is not effective against viral infections.” Yes, many people know that antibiotics have the effect of inhibiting bacterial growth and killing bacteria. But why does antibiotics seem helpless to viruses that are also pathogens? Some people probably do not know much about this. To answer this question, we must first understand the virus and bacteria what is the difference.
