The disease was supposed to be gone from the United States. How did it show up in a secluded community?

POLIO HAS RESURFACED in central Minnesota, 27 years after the last case in the United States was seen. Officials are trying to piece together how an eight-month-old Amish girl and four other children acquired the virus this past fall. Dr. Susan Rutten (shown making a house call) thinks the Amish, who often choose not to get vaccinated, have acquired the infectious disease either from traveling outside the United States or from contact with a foreign visitor. “If polio is in this community,” says Rutten, “I guarantee it’s in other parts of the country.”
