For instance, rabies—a viral disease that infects the central nervous system—can drive people to be violently mad.
Though dead humans can't come back to life, certain viruses can induce such aggressive, zombie-like behavior
If the genetic code of the rabies virus experienced enough changes, or mutations, its incubation time could be reduced dramatically, scientists say.
Many viruses have naturally high mutation rates and constantly change as a means of evading or bypassing the defenses of their hosts.
There are various ways viral mutations can occur, for example through copying mistakes during gene replication or damage from ultraviolet light.
To be transmitted by air, rabies would have to "borrow" traits from another virus, such as influenza.
Different forms, or strains, of the same virus can swap pieces of genetic code through processes called reassortment or recombination.
