Rabies is a viral disease that causes acute encephalitis in warm-blooded animals.It is zoonotic , most commonly by a bite from an contaminated animal but sometimes by other forms of contact. Rabies is almost inevitably fatal if post-exposure prophylaxis is not implemented prior to the onset of severe symptoms. The rabies virus infects the central anxious system, eventually causing disease in the brain and death. The earlier indicators of rabies in people are similar to that of many other health problems, including fever, headache, and general listlessness or discomfort. As the illness progresses, more specific symptoms seem and may include insomnia, anxiety, confusion, slight or partial paralysis, excitation, hallucinations, agitation, hypersalivation, difficulty swallowing, and hydrophobia (fear of water). Death usually occurs within days of the onset of these symptoms.

The rabies virus journeys to the brain by following the peripheral nerves. The incubation period of the disease is usually a few months in humans, depending on the distance the virus must travel to reach the central nervous system.Once the rabies virus reaches the central nervous system and symptoms begin to show, the infection is successfully untreatable and usually fatal within days.
Early-stage symptoms of rabies are malaise, head ache and fever, progressing to acute pain, violent movements, unrestrained excitement, depressive disorders, and hydrophobia.Finally, the patient may experience periods of mania and lethargy, eventually leading to coma. The primary cause of death is usually respiratory insufficiency. Worldwide, the vast majority of human rabies cases (approximately 97%) come from dog bites. In the Usa, however, animal control and vaccination programs have effectively eliminated domestic dogs as reservoirs of rabies. In several countries, including the Uk, Estonia and Japan, rabies carried by animals that live on the ground has been eradicated entirely. Concerns exist about airborne and mixed-habitat animals including bats. Bats in the U.K. and in some other countries carry European Bat Lyssavirus 1 and European Bat Lyssavirus 2. The symptoms of these viruses are similar to those of rabies and so the viruses are both known as bat rabies. An unvaccinated Scottish bat handler died from an EBLV infection in 2002.
