I don't think it's the right place to post this question. You should
probably post it to bionet.virology.
Anyway, it should be related to the methods different virii use to infect
their host, the host system they target (brain dammages are less
"recoverable" than foot dammages), the rate of replication of the virions
(virus particles), etc.
Hope it can give you some hints to refine your search.
