A popular term, now almost obsolete, for rabies.
Exaggerated fear of water as in rabies
(hydrophobia) n. an acute virus disease of the central nervous system that affects all warm-blooded animals and is usually transmitted to humans by a bite from an infected dog. Symptoms appear after an incubation period ranging from 10 days to over a year and include malaise, fever, difficulty in breathing, salivation, periods of intense excitement, hallucinations, and painful muscle spasms of the throat induced by swallowing. In the later stages of the disease the mere sight of water induces convulsions and paralysis; death occurs within 4–5 days. Daily injections of rabies vaccine, together with an injection of rabies antiserum, may prevent the disease from developing in a person bitten by an infected animal. —rabid adj.... rabies
