摘　　要：病毒在侵染人体的开始阶段,以极小的数量、极低的密度、极隐蔽的态势隐于人体极少数细胞中,并以极少的次数、极短的时间完成复制组装翻倍的程序,呈暴发式增长,并形成巨大数量。这既是病毒的生态特性,也是其生态对策。一粒病毒经3~5次复制可达数10亿个。病毒数量扩繁至一定程度时,便集中攻击人体的供氧系统与免疫系统。病毒在两次复制组装翻倍之间脱离人体细胞,裸露移行在人的体液阶段是施药救治最佳时机。At the initial infecting stage,the virus conceals in the human cell with a small number,a low density,and a cryptic condition.Then the virus accomplishes duplication,assembling and multiplication at a short period of time.The explosive growth results in tremendous number of virus.This is the ecological trait and the ecological strategy of virus.After 3-5 times of duplication,a single virus can multiply to billions of viruses.A certain number of viruses may attack the systems of oxygen supply and immunization.Between the two stages of duplication and assembling,the virus escapes from human cell and moves freely in the body fluid.At this moment,the drug feeding and treatment measure may be the most effective.
