摘要
病毒（Virus）是一种非细胞型微生物，个体微小，结构简单，由蛋白质与核酸组成，而且核酸只含有一种类型，DNA或RNA。缺乏产生能量的酶系统，只能在敏感的活细胞内以复制方式进行增殖，为严格的细胞内寄生。病毒性感染涉及临床各科，随着高新技术的不断发展，发现许多疾病均与病毒感染密切相关。
Virus is a non cellular micro-organism. Virus is tiny and simple in the structure, and consists of protein and nucleic acid. Its nucleic acid only contains a kind of type, that is, DNA or RNA. Virus is short of enzymatic system of energy production and proliferates by replication in susceptive living cells. Virus is strictly an intracellular parasitism. With the development of high technique, virus infection are found to associate with many diseases.
