U.S. doctors are warning of an emerging polio-like disease in California where up to 20 people have been infected. A meeting of the American Academy of Neurology heard that some patients had developed paralysis in all four limbs, which had not improved with treatment. The U.S. is polio-free, but related viruses can also attack the nervous system leading to paralysis.
