Rabies is a viral disease that affects the central nervous system (brain and spinal cord) in mammals. It is mainly spread through bites and scratches from infected animals such as dogs, cats, bats, raccoons, skunks, and foxes.
Most people with polio do not feel sick. Some people have only minor symptoms, such as fever, tiredness, nausea, headache, nasal congestion, sore throat, cough, stiffness in the neck and back, or pain in the arms and legs. In rare cases, polio infection causes permanent loss of muscle function (paralysis). Polio can be fatal if the muscles used for breathing are paralyzed or if there is an infection of the brain.
Seek emergency medical care immediately after any possible rabies exposure. Once symptoms of rabies develop, no treatment is available, and it is nearly always fatal.
