On September 17th, 1998 the Ithaca Journal ran its first "Ask A Scientist!"
article in which Professor Neil Ashcroft , who was then the director of
CCMR, answered the question "What is Jupiter made of?" Since then, we have
received over 1,000 questions from students and adults from all over the
world. Select questions are answered weekly and published in the Ithaca
Journal and on our web site. "Ask A Scientist!" reaches more than 21,000
Central New York residents through the Ithaca Journal and countless others
around the world throught the "Ask a Scientist!" web site.
Across disciplines and across the state, from Nobel Prize winning scientist
David Lee to notable science education advocate Bill Nye, researchers and
scientists have been called on to respond to these questions. For more than
seven years, kids - and a few adults - have been submitting their queries
to find out the answer to life's everyday questions.

Rabies: Passed through saliva
How did animals get to have rabies?

Rabies is caused by a virus belonging to the family Rhabdoviridae. It was
first recognized over 3000 years ago, and is now found on all continents
A virus is a very small and simple organism that must live inside an animal
to survive. It is made up of a single genetic (RNA) strand, a protein
cover, and an outer envelope. Rabies is most often transmitted via saliva

*Rabies* (/ËreÉªbiËz/; from Latin: /rabies/, "madness") is a viral
disease that causes acute encephalitis in warm-blooded animals.^ The
disease is zoonotic, meaning it can be transmitted from one species to
another, such as from dogs to humans, commonly by a bite from an infected
animal. For a human, rabies is almost invariably fatal if postexposure
prophylaxis is not administered prior to the onset of severe symptoms. The
rabies virus infects the central nervous system, ultimately causing disease
in the brain and death.
The rabies virus travels to the brain by following the peripheral nerves.
The incubation period of the disease is usually a few months in humans,
depending on the distance the virus must travel to reach the central
nervous system.^ Once the rabies virus reaches the central nervous
system and symptoms begin to show, the infection is virtually untreatable
and usually fatal within days.
Early-stage symptoms of rabies are malaise, headache and fever, progressing
to acute pain, violent movements, uncontrolled excitement, depression, and
hydrophobia.^ Finally, the patient may experience periods of mania and
lethargy, eventually leading to coma. The primary cause of death is usually
Rabies causes about 55,000 human deaths annually worldwide.^ 95% of
human deaths due to rabies occur in Asia and Africa.^ Roughly 97% of
human rabies cases result from dog bites.^ In the United States, animal
control and vaccination programs have effectively eliminated domestic dogs
as reservoirs of rabies.^ In several countries, including Australia
