Picture of Hand-Foot-and-Mouth Disease in Mouth 2
Hand, foot, and mouth disease is a common viral infection that frequently affects infants and children under the age of 5. The illness is caused by several types of enteroviruses. Coxsackievirus A16 is the most common viral cause of hand, foot, and mouth disease in the U.S. Early symptoms of the illness include sore throat, fever, malaise, and reduced appetite. Over the next 1 to 2 days, mouth sores develop, which turn into ulcers. Sometimes these lesions can be very painful and make it difficult to eat and drink. A skin rash may also appear on the soles and palms.
