The first outbreak of polio in the United States struck Rutland County, Vermont, in the summer of 1894. The disease began with fever, sore throat, and fatigue; it sometimes went on to damage the brain and spinal cord, paralyzing or even killing its hosts. Charles Caverly, a local physician, chronicled the devastation using detailed maps and notes. “Boy, 10 years; died within twenty-four hours with convulsions,” he wrote. “Boy, 10 months; died on sixth day, all extremities paralyzed. . . . Girl, 11 years; died on third day, no paralysis noted. . . . Male, 22 years; died on third day, both legs paralyzed.” Within weeks, a hundred and thirty-two people, mostly children, had been paralyzed, and eighteen had died.
