In the animal kingdom, what exactly does rabies do to a person or animal once they contract the disease? Share

Answer 1

Rabies (from a Latin word meaning rage) is a viral disease that causes acute encephalitis in animals and people. It can affect most species of warm-blooded animals, but is almost non-existent among herbivores, and some species of hyena may carry the virus but don't develop the disease. In unvaccinated humans, rabies is almost invariably fatal once full-blown symptoms have developed, but prompt post-exposure vaccination usually prevents symptoms from developing.


The stereotypical image of an infected ("rabid") animal is a dog foaming at the mouth; however cats, ferrets, raccoons, skunks, foxes, wolves, coyotes, bears, and bats can also become rabid. Squirrels, chipmunks, other rodents (except beavers) and rabbits are very seldom infected, perhaps because they would not usually survive an attack by a rabid animal. Rabies may also be present in a so-called "paralytic" form, rendering the infected animal unnaturally quiet and withdrawn.

The virus is usually present in the saliva of a symptomatic rabid animal; the route of infection is nearly always by a bite. By causing the infected animal to be exceptionally aggressive, the virus ensures its transmission to the next host. Transmission has occurred via an aerosol through mucous membranes; transmission in this form may have happened in people exploring caves populated by rabid bats. Transmission from person to person is extremely rare, though it can happen through transplant surgery (see below for recent cases), or even more rarely through bites or kisses.

After a typical human infection by animal bite, the virus directly or indirectly enters the peripheral nervous system. It then travels along the nerves towards the central nervous system. During this phase, the virus cannot be easily detected within the host, and vaccination may still confer cell-mediated immunity to pre-empt symptomatic rabies. Once the virus reaches the brain, it rapidly causes encephalitis and symptoms appear. It may also inflame the spinal cord producing myelitis.

The period between infection and the first flu-like symptoms is normally 3–12 weeks, but can be as long as two years. Soon after, the symptoms expand to cerebral dysfunction, anxiety, insomnia, confusion, agitation, abnormal behaviour, hallucinations, progressing to delirium. The production of large quantities of saliva and tears coupled with an inability to speak or swallow are typical during the later stages of the disease; this can result in "hydrophobia". Death almost invariably results 2–10 days after the first symptoms; the handful of people who are known to have survived the disease were all left with severe brain damage, with the recent exception of Jeanna Giese

Answer 2

The results are about the same in humans and animals: the disease causes lesions to the nervous system, which results in brain damage, often triggering violent psychotic episodes, and eventually will damage the autonomic system to the point that the person or animal dies an agonizing death.

Answer 3

it affects the neurological system and the brain, and causes aggression, which helps it to be spread through it's mechanism of bites. The brain damage becomes fatal shortly after symptoms begin to show.

Answer 4

Any mammal can get it through contact with the saliva or blood of an infected animal. Look it up in www.wikipedia.com for all the symptoms and details.

Answer 5

They develop neurological symptoms and DIE!!!!!!!!!! It is FATAL!! Once there are symptoms, it is too late.
Symptoms can very from case to case, but it attacks the neuro system.
