抗细菌和螺旋体感染的化学制剂近几十年来已有迅速发展,然而病毒性疾病的治疗问题尚未真正解决,疫苗的出现虽使某些疾患(如天花、脊髓灰质炎、乙型脑炎、麻疹、狂犬病与黄热病)得到控制,但至今仍有许多常见的病毒(鼻、柯萨奇、冠状、流感、副流感、单纯疱疹和肝炎病毒等)感染缺乏有效的特异性预防措施。可见,抗病毒药物更显得十分重要了。 Antibacterial and spirochete chemical agents have been rapidly developed in recent decades. However, the treatment of viral diseases has not yet been fully solved. Although the emergence of vaccines has led to certain diseases (such as smallpox, polio, Japanese encephalitis, measles , Rabies and yellow fever), there are still many effective and specific preventive measures against many common infections (nasal, coxsackie, coronavirus, parainfluenza, herpes simplex and hepatitis virus). Visible, antiviral drugs even more important.
