If someone is bitten by a rabid animal and prompt medical care isn’t available, it can spread in the body. 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.
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).

Jeanna Giese-Frassetto, the first person to survive rabies without being vaccinated, became a mom when she gave birth to twins Carly Ann and Connor Primo on March 26, 2016. In 2004, Jeanna was bitten by a bat she rescued from her church in Fond du Lac, Wisconsin, but did not seek medical attention.
How did Jeanna Giese survive rabies?
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.

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.

Can you survive rabies without treatment?
People Can Survive Rabies Without Treatment. Image REUTERS/Handout . Common belief says that a bite from a rabies-infested animal can lead to death unless immediate treatment is given. A new study has challenged this idea by finding cases where people did not receive medical treatment and have survived after being infected with rabies.

This means there may be ways to develop effective treatments that can save lives in areas where rabies remains a persist ent cause of death," said Amy Gilbert with the CDC's National Center for Emerging and Zoonotic Infectious Diseases, and the paper's lead author.
What is the weakened form of rabies?
The Rabies Vaccine. Like all vaccines, rabies vaccines contain a weakened form of the virus that is incapable of causing disease or reproducing. In response to the vaccine, your body produces antibodies that target and kill the rabies virus.
How long does it take to die from rabies?
Once symptoms set in, however, death from respiratory failure usually occurs within seven days —even if treatment is given.
What is PEP in rabies?
Post-exposure prophylaxis (PEP) is the only treatment strategy known to prevent rabies-related deaths. 4 This treatment includes extensive washing and local treatment of the wound followed by a course of a potent and effective rabies vaccine.
What is the first category of exposure to rabies?
The guidelines identify three categories of rabies exposure. The first category is defined as "touching or feeding animals, licks on intact skin," but post-exposure prophylaxis (PEP) is recommended only for category 2 and category 3 exposure. 8.
What animals are most likely to get rabies?
2 The rabies virus may also be spread by such animals as foxes, skunks, and raccoons. Across the globe, over 90 percent of human rabies cases result from virus transmission by domestic dogs. 3 .
What to do after a rabies bite?
In addition to seeking medical attention right after an animal bite (especially from a bat, fox, or skunk), the wound should be cleaned immediately and thoroughly.
Can rabies cause nausea?

The World Health Organization (WHO) wants to eliminate rabies from the South-East Asia region by the year 2020. It is a goal that India is unlikely to meet, public health experts say.
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.
What is the rabies immunoglobulin?
The rabies immunoglobulin binds to the rabies virus lodged in Veena and Bhuvan’s wounds, preventing it from entering their nerve endings. Meanwhile, the initial anti-rabies vaccine they were given at the local hospital continues its work, prompting their bodies to produce their own antibodies.

The period between infection and the first symptoms (incubation period) is typically 1–3 months in humans. This period may be as short as four days or longer than six years, depending on the location and severity of the wound and the amount of virus introduced. Initial symptoms of rabies are often nonspecific such as fever and headache. As rabies progresses and causes inflammation of the brain and meninges, symptoms can include slight or partial paralysis, anxiety, insomnia, confusion, agitation, abnormal behavior, paranoia, terror, and hallucinations. The person may also have fear of water.
