Thanks to widespread pet vaccinations, effective post-exposure treatment and the relative rarity of undetected bites by rabid animals, the number of human deaths from rabies in the United States caused has declined to an average of only one or two per year—far less than the number of human fatalities caused by lightning strikes. But this doesn't mean you shouldn't take precautions to protect yourself, your family and your pets. The best ways to guard against rabies:

Don't approach or handle wild animals, especially sick wild animals.

Vaccinate your pets.

Get prompt post-exposure treatment when advised to do so by a doctor or health department.

What is rabies?

Rabies (Lyssavirus) is an infectious disease that affects the central nervous system in mammals. It's transmitted through the saliva a few days before death when the animal "sheds" the virus. Rabies is not transmitted through the blood, urine or feces of an infected animal, nor is it spread airborne through the open environment. Because it affects the nervous system, most rabid animals behave abnormally.

Signs of rabies in animals

In the "furious" form, wild animals may appear to be agitated, bite or snap at imaginary and real objects and drool excessively. In the "dumb" form, wild animals may appear tame and seem to have no fear of humans.

There are other signs, such as the animal appearing drunk or excessively wobbly, circling, seeming partially paralyzed, acting disorientated or mutilating itself. However, most of these signs can also be indicative of other diseases like distemper or lead poisoning. There are few behavioral signs that are telltale of rabies alone.

If a typically nocturnal animal, such as a raccoon or skunk, is active during the day and exhibiting abnormal behavior, you should seek advice from your local animal control, animal organization, wildlife rehabilitator or state wildlife agency.
