Hand-foot-and-mouth disease is a common illness caused by a virus. The virus is very contagious. It spreads easily through contact with stool, coughs, sneezes, and runny noses. Anyone can get hand-foot-and-mouth disease, but it's most common in children.

Symptoms are usually mild. They often include blisters and sores on the hands and feet and in the mouth. The symptoms usually go away in about 7 to 10 days. Home care can help relieve the symptoms.
