what are the symptoms of polio
There are two forms of polio: Minor poliomyelitis (also called abortive poliomyelitis) occurs primarily in young children, and is the more common of the two forms. The illness is mild, and the brain and spinal cord are not affected. Symptoms appear three to five days after exposure to the virus and include slight fever, headache, sore throat, vomiting, lack of appetite, and a general feeling of illness and discomfort. Major poliomyelitis is a more severe illness that develops approximately 7 to 14 days after exposure to the virus. Symptoms include fever, severe headache, stiff neck and back, and deep muscle pain. Some people experience temporary abnormalities of skin sensation.
