Polio

What is the history of polio?

Polio is caused by a virus and has been around for thousands of years. There are even Egyptian artifacts portraying individuals with typical features of post-polio paralysis. Polio has been called many different names, including infantile paralysis, debility of the lower extremities, and spinal paralytic paralysis. We now refer to the virus and disease as polio, which is short for poliomyelitis and has Greek derivation: polios (gray), myelos (marrow), and itis (inflammation).

Polio is caused by a very infectious enterovirus, poliovirus (PV), which primarily affects young children and is spread through direct person-to-person contact, with infected mucus, phlegm, feces, or by contact with food and water contaminated by feces of another infected individual. The virus multiplies in the gastrointestinal tract where it can also invade the nervous system, causing permanent neurological damage in some individuals.

Most individuals infected with polio remain asymptomatic or develop only mild flu-like symptoms, including fatigue, malaise, fever, headache, sore throat, and vomiting. In fact, the symptoms, if present, may only last 48-72 hours; however, those individuals will continue to shed virus in their stools for a prolonged period, serving as a reservoir for subsequent infections. About 2%-5% of infected individuals go on to develop more serious symptoms that may include respiratory problems and paralysis. Currently, there is no cure for polio; only vaccination can prevent the spread of the disease, and although in the developed world it is almost unheard of, globally, polio remains a fairly common disease. Originally, international organizations believed it possible to eradicate polio by 2000, though this has been more difficult than initially hoped for.

  • Related Diseases & Conditions

    • Sore Throat (Pharyngitis)
      • Most sore throats are caused by viruses or mechanical causes (such as mouth breathing) and can be treated successfully at home. However, a person should be seen by a health care professional if they have a sore throat that has a rapid onset, and is associated with a fever or tenderness of the front of the neck; a sore throat that causes the person to have difficulty swallowing (not just pain swallowing) or breathing; or if a sore throat lasts for more than a week.
    • Headache
      • Headaches can be divided into two categories: primary headaches and secondary headaches. Migraine headaches, tension headaches, and cluster headaches are considered primary headaches. Secondary headaches are caused by disease. Headache symptoms vary with the headache type. Over-the-counter pain relievers provide short-term relief for most headaches.
    • Constipation
      • Constipation is defined medically as fewer than three stools per week and severe constipation as less than one stool per week. Constipation usually is caused by the slow movement of stool through the colon. There are many causes of constipation including medications, poor bowel habits, low fiber diets, abuse of laxatives, hormonal disorders, and diseases primarily of other parts of the body that also affect the colon.
    • Muscle Spasms
      • Muscle spasms are involuntary muscle contractions that come on suddenly and are usually quite painful. Dehydration, doing strenuous exercise in a hot environment, prolonged muscle use, and certain diseases of the nervous system may cause muscle spasms. Symptoms and signs of a muscle spasm include an acute onset of pain and a possible bulge seen or felt beneath the skin where the muscle is located. Gently stretching the muscle usually resolves a muscle spasm.
    • Nausea and Vomiting
      • Nausea is an uneasiness of the stomach that often precedes vomiting. Nausea and vomiting are not diseases, but they are symptoms of many conditions. The causes of vomiting differ according to age, and treatment depends upon the cause of nausea and vomiting.
    • Fever
      • Although a fever technically is any body temperature above the normal of 98.6 degrees F. (37 degrees C.), in practice a person is usually not considered to have a significant fever until the temperature is above 100.4 degrees F (38 degrees C.). Fever is part of the body's own disease-fighting arsenal: rising body temperatures apparently are capable of killing off many disease- producing organisms.
    • Muscle Pain (Myofascial Pain Syndrome)
      • Myofascial pain syndrome is muscle pain in the body's soft tissues due to injury or strain. Symptoms include muscle pain with tender points and fatigue. Treatment usually involves physical therapy, massage therapy, or trigger point injection.
    • Post-Polio Syndrome
      • Post-polio syndrome (PPS) is a group of signs and symptoms that show up two to four decades after the initial polio infection. Symptoms of PPS include fatigue, pain, sleep disorders, muscle twitching, gastrointestinal problems, and weakness. Treatment focuses on slowing down to conserve energy and relieving symptoms with pain relievers.
    • Children's Health
      • Children's health is focused on the well-being of children from conception through adolescence. There are many aspects of children's health, including growth and development, illnesses, injuries, behavior, mental illness, family health and community health.

What is a headache?

A Headache is defined as a pain in the head or upper neck. It is one of the most common locations of pain in the body and has many causes.

How are headaches classified?

Headaches have numerous causes, and in 2007 the International Headache Society agreed upon an updated classification system for headache. Because so many people suffer from headaches and because treatment sometimes is difficult, it is hoped that the new classification system will allow health care practitioners come to a specific diagnosis as to the type of headache and to provide better and more effective treatment.

There are three major categories of headaches:

  1. primary headaches,
  2. secondary headaches, and
  3. cranial neuralgias, facial pain, and other headaches

What are primary headaches?

Primary headaches include migraine, tension, and cluster headaches, ...
