He may be just 6 years old, but Hyde Talbot has made a huge impact on research into a rare disorder. Diagnosed with hemolytic-uremic syndrome, more commonly known as Atypical HUS, at 18 months, Talbot and his family began an annual fundraiser five years ago to raise money for the Foundation for Children with Atypical HUS and Children’s Healthcare of Atlanta. That fundraiser, called Hike 4 Hyde, was held again Saturday at Sawnee Mountain Preserve.
