It is an infectious disease caused by one of three viruses. After initial flu like symptoms, the virus can attack the spinal cord, causing muscle paralysis, which can affect any part of the body. In the 1950s polio epidemics in the British Isles affected thousands of children and adults. If the virus attacks the nerves supplying the arms and legs they become weak or paralysed.
Some people also have back problems.
Any of these symptoms can result in permanent disability. The site has been put together by an American science reporter, Alan Dove, who trained as a molecular microbiologist. As well as being packed full of information itself, it provides a vast range of links to other polio related sites. Well worth a look.
