控制病毒感染的理想方法是预防,多种病毒疾病如麻疹、风疹、流行性腮腺炎、脊髓灰白质炎及狂犬病已可用疫苗防止。但对一些严重的病毒感染如疱疹脑炎、新生儿疱疹,播散性水痘一带状疱疹(VZV)和细支气管炎等,尚缺乏有效的疫苗控制,加上流感病毒抗原成分不断变化,如鼻病毒有90种不同抗原的毒株,难以制备一种疫苗有效地防止。因而迫切需要发展有效而安全的抗病毒 The ideal method of controlling a viral infection is prevention, and a number of viral diseases such as measles, rubella, mumps, myeloplasminosis and rabies have been vaccinated against it. However, there is a lack of effective vaccine control for some serious viral infections such as herpes zoster, herpes zoster, varicella-zoster virus (VZV) and bronchiolitis, as well as the constant changes in the composition of influenza virus antigens such as Rhinovirus has 90 strains of different antigens, making it difficult to prepare a vaccine that is effectively prevented. There is an urgent need to develop effective and safe antivirals
