Let me tell you a story...When I was your age many children suffered from Poliomyelitis (or "polio"). I remember a girl in my primary school class who had to wear calipers on her legs. My Aunt had polio as a child and the result was that one of her legs was shorter that the other. She always wore a built-up shoe so that both of her legs appeared the same length. Many people who contacted Polio were either paralysed or died.
Poliomyelitis (or "polio") is a viral infection.The World Health Organisation reports that "many countries have eliminated indigenous polio and in some instances more than ten years have passed since the last reported case of polio." Explain how polio may be contracted. Suggest why the global numbers of poliomyelitis have fallen since 1981. |
