Rabies is a viral
disease that affects all warm-blooded animals, including humans. The virus
is transmitted though saliva when an affected animal bites a susceptible
victim. On rare occasions, the rabies virus can enter the body through deep
scratch wounds (or any break in the skin or mucous membranes) or by
inhalation. Inhalation of the virus is an unusual method of transmission;
however, it can occur in caves that are heavily populated by rabid bats. |

A rabid animal bites
its victim and injects saliva containing the rabies virus. In the newly
infected animal, the virus begins to multiply. Virus multiplication occurs
in the area surrounding the bite wound. After a period of time, virus
particles enter large nerves and travel toward the spinal cord and brain.
Once inside the brain, the rabies virus multiplies a second time. As
multiplication occurs, viruses pass to the salivary glands. This is
particularly important and accounts for the danger associated with saliva. |

Early symptoms include
personality changes. Friendly animals become shy, and reserved animals often
become aggressive. |
| |
|
Two forms rabies are
recognized: the "furious" or "mad" type and the "paralytic" or "dumb" form. |
| |
|
The most common form of
rabies is the furious type. Animals hallucinate and snap at imaginary
objects. A rabid animal is extremely aggressive and may attack or bite other
animals as well as his (or her) owner. Other signs include excitation,
irritability, photophobia (extreme sensitivity to light) and seizures. |

In the United States,
wild animals are the reservoir for the rabies virus. Common carriers are
raccoons, foxes, and bats are commonly infected. Raccoons are particularly a
problem due to their presence in urban and suburban areas. Pets become
infected when they come into contact with these animals (and are bitten). |

Vaccinating pets
protects them from rabies! |
| |
|
Vaccinations begin at
three to four months of age and should be continued throughout the animal's
life. |
