What is rabies?
Rabies is a disease that affects the body's central nervous system (brain, spinal cord, and nerves). Rabies is caused by a virus. You may get the virus if you come into contact with the saliva or other tissue of an infected animal. Rabies infection usually happens through a bite wound. Animals that may spread rabies include dogs, cats, coyotes, raccoons, foxes, skunks, and bats. Rabies develops when the virus enters the skin and goes to the muscles or nerves. Without early treatment, rabies damages the brain and other organs. You may have brain swelling, seizures, and paralysis. Rabies can be life-threatening.
What increases my risk for rabies?
Rabies can affect anyone of any age. The following may increase your risk:
- You were bitten on the head, face, neck, or hands. Even a small bite from a bat can increase your risk for rabies.
- You were bitten many times during an attack, or you have deep bite wounds.
- You have a weak immune system from medicine such as steroids or a disease such as HIV/AIDS.
- You travel to places where rabies is common.
- You have a job that includes handling the virus or working with animals. These jobs may include laboratory workers, veterinarians, forest rangers, and animal control and wildlife workers.
What are the early signs and symptoms of rabies?
Signs and symptoms of rabies may appear weeks, months, or even years after the infection. During the early stages of rabies, you may feel like you have the flu. You may have one or more of the following signs and symptoms for up to 10 days:
- Weakness, fever, headache, and irritability
- Loss of appetite, nausea, and vomiting
- Pain, numbness, or burning or tingling that may slowly spread to other areas
- Severe itching at the bite site
What are the late signs and symptoms of rabies?
Over time, rabies may affect the brain. Symptoms may include any of the following:
- Confusion or insomnia
- Dizziness, seeing double, or seeing something that is not really there
- Restlessness, anxiety, and hyperactivity increased by thirst, fear, light, or noise
- Seizures or twitching
- Slurred speech, drooling, swallowing problems, and a fear of water
- Tiredness, muscle cramps, or trouble moving
- Severe weakness that may be only on one side of the body or face
How is rabies diagnosed?
Your healthcare provider will ask if you have been bitten by an animal and how the animal behaved before it bit you. He will ask about vaccinations you have received, and your past travels. You may need any of the following tests:
- Blood tests are done to look for antibodies to the rabies virus. Antibodies are substances that the immune system makes to protect the body from outside organisms. You may need to have blood drawn more than once.
- A biopsy is done to remove a small piece of skin to be tested for the cause of your symptoms. A skin sample is usually taken from the back of the neck.
- Cultures are done to test your saliva, tears, or fluid around the brain and spinal cord.
- A lumbar puncture , or spinal tap, may be done to check the fluid around your brain and spinal cord for the rabies virus.
- A CT or MRI may be used to check for signs of swelling or infection in your brain.
How is rabies treated?
The main goal of treatment is to prevent the virus from spreading inside the body. Treatment as soon as possible may prevent more serious problems and increase recovery.
- Clean the bite wound. Use a povidone-iodine solution mixed with water. Use soap and water if the iodine solution is not available. Your risk for infection and rabies decreases if your wound is cleaned soon after you are bitten. Healthcare providers may need to close the wound with stitches.
- You may need to get the rabies vaccine. The rabies vaccine helps your body make antibodies to fight the virus and helps prevent rabies. Ask for more information about the rabies vaccine.
- Rabies immune globulin medicine may be given. If you have been exposed to rabies, you may be given rabies immune globulin to attack the virus. This medicine will also help your immune system fight the infection. You will not be given this medicine if you have been given the rabies vaccine in the past.
What can I do to prevent rabies?
- Ask your healthcare provider about the rabies vaccine. You may need the vaccine if your work puts you at risk for rabies. You may also need shots if you plan to travel to places where the risk for rabies is high. Ask for more information on rabies shots.
- Avoid contact with wild animals. Do not approach any tame or wild animal that you do not know. Do not try to take them home with you. Cover windows and other openings in your home with screens so wild animals cannot get inside.
- Get medical care if you get bitten by an animal. Do this even if the wound is very small.
- Get your pet vaccinated against rabies. You will need to do this every 3 years or as directed by your veterinarian.
