Rabies primarily targets the central nervous system (CNS), specifically attacking the brain and spinal cord. It is a highly neurotropic virus that travels from the site of infection through nerves to the brain, causing severe inflammation (encephalitis). The virus also spreads to the salivary glands.

What is the target organ of the rabies virus?

As the virus moves to the central nervous system, progressive and fatal inflammation of the brain and spinal cord develops. Clinical rabies in people can be managed but very rarely cured, and not without severe neurological deficits.

What organs does rabies affect?

Rabies is a viral infection of the brain that is transmitted by animals and that causes inflammation of the brain and spinal cord. Once the virus reaches the spinal cord and brain, rabies is almost always fatal.

Why does rabies target the nervous system?

Successful invasion of the nervous system by RABV seems to be the result of a subversive strategy based on the survival of infected neurons. This strategy includes protection against virus-mediated apoptosis and destruction of T cells that invade the CNS in response to infection.

What part of the body does the rabies virus primarily affect?

Rabies primarily affects the central nervous system, leading to severe brain disease and death if medical care is not received before symptoms start. After a rabies exposure, the rabies virus must travel to the brain before it can cause symptoms.

Does rabies affect the kidneys?

Renal problem in rabies is possible but little mentioned. Rabies might induce glomerular and renal tubular disorder. Rabies might be transmitted to renal transplant recipients if there is no good donor screening.

What organ recipient died of rabies?

Rabies is almost always fatal without prompt treatment. The Michigan transplant recipient died at the end of January 2025. After his death, an investigation located kidney biopsy samples in which the CDC detected rabies virus RNA consistent with a silver-haired bat rabies virus variant.

Has a human ever survived rabies?

Human rabies has a very high fatality rate and there have only been about 34 well-documented survivors, defined as survival at 6 months after onset of clinical rabies. Many have had serious neurological sequelae.

Why is rabies afraid of water?

Rabies patients fear water (hydrophobia) because the virus attacks the brain, causing excruciatingly painful, involuntary spasms in the throat muscles when trying to swallow liquids, even just thinking about them. This isn't a psychological fear of water itself, but a physical reaction to the choking pain, forcing them to avoid drinking, which paradoxically helps the virus spread through their saliva.
 

Why can't we cure rabies?

There's no cure for rabies once it's moved to your brain because it's protected by your blood-brain barrier. Your blood-brain barrier is a layer between your brain and the blood vessels in your head.

Is rabies virus killed by heat?

Inac- tivated on exposure to ultraviolet radiation, by heat (1 h at 50°C), and by lipid solvents. Rabies virus is inactivated rapidly in sunlight and does not survive for long periods out of the host unless protected in a cool, dark area.

Do only mammals carry rabies?

Humans and all warm-blooded animals can get rabies. Most cases in domestic animals occur in cats, dogs, cattle and horses. Rabies is rarely seen in rodents such as mice, rats, squirrels, chipmunks, guinea pigs, hamsters, or rabbits. Birds, turtles, lizards, fish and insects do not get rabies.

Can animals with rabies be friendly?

Why can't you drink water if you have rabies?

How painful is rabies?

Where is rabies most common in the United States?

Midwestern United States

The most widely distributed reservoir of rabies in the United States, however, and the source of most human cases in the U.S., are bats. All five of the human rabies cases in the Midwest from 2009 to 2018 were identified genetically as strains of rabies from bats.
