When a young adult in a New York City suburb visited an emergency department in June after experiencing weakness in their lower legs, the shocking diagnosis would lead local officials to declare a health emergency in New York and put authorities across the U.S. and around the world on a state of alert.
The individual, a resident of Rockland County, had suffered from a fever, a stiff neck, back and abdominal pain as well as constipation for five days. The patient was hospitalized and tested for enterovirus, a family of pathogens that in rare cases can cause weakness in the arms and legs.
New York state’s Wadsworth Center and the Centers for Disease Control and Prevention would subsequently confirm the worst: The young adult was suffering from paralysis after contracting polio, the first known U.S. case in nearly a decade and the first in New York since 1990.
