Rabies. The period between infection and the first flu-like symptoms is typically 2 to 12 weeks, but incubation periods as short as four days and longer than six years have been documented, depending on the location and severity of the inoculating wound and the amount of virus introduced. Soon after, the symptoms expand to slight or partial paralysis, anxiety, insomnia, confusion, agitation, abnormal behavior, paranoia, terror, and hallucinations, progressing to delirium.[2][9] Rabies has been called hydrophobia because victims, locally paralyzed and unable to swallow, have been known to become agitated at the sight of water.[10] Death almost invariably results 2 to 10 days after first symptoms. Once symptoms have presented, survival is rare, even with the administration of proper and intensive care. Rabies can be difficult to diagnose, as in the early stages it is easily confused with other diseases or aggressiveness. Because of its potentially violent nature, rabies has been known since circa 2000 B.C The term is derived from the Latin rabies, "madness".[65] This, in turn, may be related to the Sanskrit rabhas, "to do violence."
