Rabies is a virus that travels through the nerves to reach your brain and spinal cord, which together make up your central nervous system. Because it attacks this system, it causes severe inflammation, or swelling, in the brain.
The virus is found in the saliva of infected mammals. When an animal bites you or scratches you, the virus enters your body through the wound and begins its slow journey toward your brain. Once it reaches the brain, it is nearly always fatal, which is why immediate medical care is essential.
Common Symptoms
- Fever and headache.
- Tingling, pricking, or burning sensations at the site of the bite.
- Extreme sensitivity to bright lights or loud noises.
- Trouble swallowing or feeling like you are choking.
- A fear of water, called hydrophobia, because swallowing causes painful throat spasms.
- Confusion, agitation, or becoming very excited.
