Rabies is an infectious disease of animals which is a member of a group of
viruses constituting the family Rhabdoviridae. The virus particle is covered in

Although rabies is usually spread among domestic dogs and wild carnivorous
animals, all warm-blooded animals are susceptible to infection. The virus is
often present in the salivary glands of infected animals, referred to as rabid,
and is excreted in the saliva. The bite of the infected animal easily
introduces the virus into a fresh wound. In humans, rabies is not usually spread
from man to man, rather the majority of infections occur from rabid dogs. After
