Researchers have identified a polio-like syndrome in a cluster of children from California over a one-year period, according to a case report released. Polio is a contagious disease that sometimes caused paralysis. The United States experienced a polio epidemic in the 1950s, until a vaccine was introduced. The five children experienced paralysis of one or more arms or legs that came on suddenly and reached the height of its severity within two days of onset. Three of the children had a respiratory illness before the symptoms began. All of the children had been previously vaccinated against poliovirus. The children were treated but their symptoms did not improve and they still had poor limb function after six months.
