"Early diagnosis and treatment is the key to prevent coronary artery aneurysms or dilation," Dr. Pei-Ni Jone, an associate professor of pediatrics at the University of Colorado School of Medicine in Aurora told TODAY, via email. "Please contact your primary care physician if your child presents with high fever, red eyes, red lips, big lymph nodes and rash so that early recognition of the diagnosis can happen. Early treatment will prevent coronary artery dilation."
