Patient: How long is a toddler with hand foot and mouth disease contagious?
Doctor: Hand-foot-and-mouth disease is most commonly caused by a coxsackievirus. It is a mild, contagious viral infection common in young children and is characterized by sores in the mouth and a rash on the hands and feet. A toddler is contagious when the first symptoms appear and may continue until the blister-like skin lesions disappear. The virus has been known to be shed in the stool for up to several weeks.
