Rabies infects the central nervous system (CNS), and — if left untreated — it can be fatal if it reaches the brain. Once it reaches the brain, there’s currently no treatment available. Researchers are still trying to find ways to treat rabies once it reaches the brain. Thankfully, rabies in people is preventable with prompt medical care.
What happens if rabies is untreated?
What happens if rabies goes untreated? Rabies is almost always fatal if it is left untreated. In fact, once someone with rabies starts experiencing symptoms, they usually do not survive. This is why it is very important to seek medical attention right away following an animal bite, especially if the bite is from a wild animal.
Will there ever be an effective rabies treatment?
Rabies is an overwhelmingly fatal disease, with only a few documented survivors. There is no effective curative treatment for rabies once clinical signs have appeared. All cases of suspected rabies exposure should be treated immediately to prevent the onset of clinical symptoms and death. Post-exposure prophylaxis (PEP) consists of wound treatment, the administration of rabies vaccines based on WHO recommendations, and if indicated, the administration of rabies immunoglobulin (See table below).
Why does rabies require medical treatment?
- Veterinarians, animal handlers, and veterinary students
- Rabies laboratory workers
- Spelunkers (people who explore caves), and
- Persons who work with live vaccine to produce rabies vaccine and rabies immune globulin.
Why is rabies so bad for You?
- Signs of an allergic reaction, like rash; hives; itching; red, swollen, blistered, or peeling skin with or without fever; wheezing; tightness in the chest or throat; trouble breathing, swallowing, or ...
- Signs of meningitis like headache with fever, stiff neck, upset stomach, confusion, or if lights bother the eyes.
- Feeling very tired or weak.
Why don't we have a cure for rabies?
So why is rabies so difficult to treat? Viral infections can usually be treated using anti-viral drugs, which inhibit virus development. Rabies virus uses a myriad of strategies to avoid the immune system and hide from antiviral drugs, even using the blood brain barrier to protect itself once it has entered the brain.
Is it impossible to survive rabies?
As we know rabies has approximately 100% mortality rate but by using the aggressive treatment approach (like Milwaukee protocol), the patient may survive.

Giese was put into an induced coma for two weeks while feeding and breathing tubes kept her alive.
Why are rabies patients afraid of water?
People used to call rabies hydrophobia because it appears to cause a fear of water. The reason is that the infection causes intense spasms in the throat when a person tries to swallow. Even the thought of swallowing water can cause spasms, making it appear that the individual is afraid of water.
Is rabies 100 fatal in humans?

How do you prevent rabies from becoming an infection?
Prompt medical attention is vital for preventing a rabies infection. If you’ve been bit by a rabid animal — or even an animal that might have rabies — you’ll need post-exposure prophylaxis (PEP) to help protect yourself. About 55,000 people in the U.S. get PEP every year.
Can you treat rabies once symptoms of an infection develop?
After being exposed to rabies, it takes time for rabies to travel to your brain. This is known as the incubation period and can last weeks to months. This time can vary depending on the initial location of exposure.
Is there any ongoing research for rabies treatments?
Recently, the FDA released guidance for drug manufacturers to use to help develop monoclonal antibody cocktails — a type of new anti-rabies treatment. Monoclonal antibodies are biologic medications that act as artificial antibodies. The term cocktails refers to multiple monoclonal antibody medications being used at the same time.
The bottom line
Rabies is a disease that is preventable with prompt medical care, but it’s almost always fatal when it reaches your brain. Treating rabies once it reaches your brain is difficult because it’s hard to get medications into your brain.
Why is rabies so hard to treat?
So why is rabies so difficult to treat? Viral infections can usually be treated using anti-viral drugs, which inhibit virus development. Rabies virus uses a myriad of strategies to avoid the immune system and hide from antiviral drugs, even using the blood brain barrier to protect itself once it has entered the brain. The blood brain barrier is a membrane that prevents cells and large molecules from entering the brain. During infection of the brain, the permeability of the barrier can increase, allowing immune cells and antibodies through to help clear the infection. However, during infection with rabies virus, the blood brain barrier locks down, meaning nothing can get through, even antiviral drugs.
How many people have survived rabies?
Only six people are known to have survived from rabies infection after symptoms appear, making it one of the world’s deadliest viruses.

What is the rabies virus?
Rabies is a viral disease that spreads to humans from animals and infects the nerves and brain. The disease is caused by lyssaviruses; a genus of viruses in the Rhabdoviridae family.

How many times has the syringe been tried?
The Protocol has been tried over 50 times around the world, but only a handful of patients have survived, meaning this treatment is not recommended and remains highly controversial.
Who developed the first rabies shot?
Vaccines to protect against rabies infection have been around for a long time, with the first rabies vaccine developed by Louis Pasteur. In 1885, after five years of work developing a vaccine to protect dogs from the disease, Pasteur administered his vaccine on a nine-year-old boy who had been bitten by a rabid dog.
Can a virus enter a nerve?
Of course, the virus does not immediately enter a nerve following a bite or scratch from an infected animal and must replicate in other cell types until it can come into contact with, and infect, a nerve cell. During this time, there are no symptoms and the virus is at its most vulnerable to clearance by the immune system.
What to do if you get bit by an animal?
If you are bitten by an animal, quickly flush the area with generous amounts of soap and water. A vaccination process can be provided to you immediately after you have a bite. However, once a person has symptoms of rabies, there is no cure for rabies.

Why do dogs bite?
Dog bites can transmit a wide variety of bacteria and viruses. Even pet dogs may bite if they feel threatened or if they have become sick. Viruses such as rabies infect the animal’s brain, causing the dog to behave in ways that are out of character. Unlike bacterial infections of the skin that start to cause symptoms such as fever, swelling, redness, and pus, a dog bite that transmits the rabies virus will not be so obvious. Even if the bite seems minor, it is important to visit a health clinic or emergency room so that the bite can be examined. Dogs that bite should be captured by the animal control or dog warden service. They will be quarantined until proof of rabies vaccination is provided. If the dog is a stray, it may be euthanized so that veterinary pathologists can necropsy the animal and test it for rabies.
What to do if you get bit by a dog in Las Vegas?

How does rabies manifest?
The two forms differ in the path the virus takes to reach the brain. In dumb rabies, the virus travels via motor nerves, damaging them in the process and leading to a slow progression from muscle paralysis to coma.
