If the sole purpose of a virus is to hijack the nucleus of a cell to replicate, why do we have different symptoms for different viruses?
I can think of the following comming into play:
- immune response of the body
- destroying tissue of type A is different than destroying tissue of type B
- the rate of the destruction --- some (virus, cell) combination are causing more harm than others
- Why Do Viruses Cause Different Symptoms In Different People? --- talks about how we can have different symptoms for the same virus.
