Rabies

The word rabies comes from the Sanskrit rabhas, which means, "to do violence." Rabies is thought to be the oldest communicable disease of humans. Rabies also known as: hydrophobia or  lyssa (Old-World term)
it is an acute, central nervous system infection, characterized by CNS irritation, followed by paralysis and death. Rabies, a member of the Rhabdovirus family, is caused by the virus Neurotropic lyssavirus.The virus is found in the salivary glands and CNS of infected, warm-blooded animals (including humans).
There are three vectors for rabies:
First is  the bite or scratch of an infected animal, which introduces the virus through the skin or mucous  membrane. Bites (vs. nonbite exposure) cause approximately 99% of rabies cases worldwide. Wild animals account for 70% of rabies cases in the U.S.. World-wide, rabid dogs cause most cases of the disease.
Second is aerosol transmission from an infected animal, usually a bat.
Third is tissue transplants (such as corneas) from infected humans. There have been at least 6 recorded cases of humans contracting the disease from transplants of corneas from infected donors.
