Rabies is caused by the rabies virus. The virus infects the brain and ultimately leads to death. After being bitten by a rabid animal, the virus is deposited in the muscle and subcutaneous tissue. For most of the incubation period (which is usually one to three months), the virus stays close to the exposure site. The virus then travels via peripheral nerves to the brain and from there, again via peripheral nerves, to nearly all parts of the body.
Any mammal can spread rabies. In the United States, rabies is most often transmitted via the saliva of bats, coyotes, foxes, raccoons, and skunks. In the developing world, stray dogs are the most likely animal to transmit rabies. The virus has also been found in cows, cats, ferrets, and horses.
