I'll try to address this specific question a little bit.
Thank keah to correct me, first.
Yes, virus CAN be cleaned completely from the body!!
But this is really depend on specific virus. For example, Flu virus can be
efficiently cleaned, the virus we got this year, definitely is not the same
virus you will get next year. You will not carry it for your life. At least
there is no evidence for this.

发帖数: 2929 | 2 我来用中文说吧，我想senegal问的主要问题在于病毒在宿主细胞里的寿命。这里需要提
到一个概念基因组整合，某些病毒在侵染宿主细胞后需要将自身DNA整合到宿主的基因组
里，然后通过宿主的表达机制来合成和复制自身，代表的病毒就是逆转录病毒，如HIV；
但是它们并没有所谓“一次感染终生带毒”的能力，高等动物的免疫系统可以清除大部份
“外来”的蛋白（当然艾滋病毒把免疫系统破坏了，所以死翘翘），而且细胞在复制的时
候这些外来基因虽然会一起复制，但是会在纠错机制和其他未知机制的作用下部分丢失，
几代之后就几乎没有了。只有很少数的病毒片断能保存下来，甚至传给后代，不过它们大
多无害，事实上，在千万年的进化中，人的基因组里还是留下了许多病毒的痕迹，你我身
上可能都有。
另一些病毒没有基因组整合能力，它们侵入细胞之后是直接表达复制，包括冠状病毒在内
，这些病毒在宿主中的存活时间就取决于免疫系统什么时候把它们清除了。
另一个问题是病毒的毒理，这个我不太在行，我只知道不同种病毒的毒理效应差别很大，
不能拿个HIV来类比所有的病毒。希望有专家来讲解一下。
总之那篇文章的作者对病毒学一知半解，并大量用臆测来代
