The disease rabies is caused by a virus that attacks the central nervous system. The virus is normally introduced when an infected animal bites another, breaking the surface of the skin and allowing the entry of saliva containing the virus. Since the virus cannot move by itself, how does it get to neurons in the central nervous system?
