About Hand, Foot, and Mouth Disease (HFMD)
Hand, foot, and mouth disease is a common viral illness that usually affects infants and children younger than 5 years old. However, it can sometimes occur in adults. Symptoms of hand, foot, and mouth disease include fever, blister-like sores in the mouth (herpangina), and a skin rash.
Hand, foot, and mouth disease is caused by viruses that belong to the Enterovirus genus (group). This group of viruses includes polioviruses, coxsackieviruses, echoviruses, and enteroviruses.
- Coxsackievirus A16 is the most common cause of hand, foot, and mouth disease in the United States, but other coxsackieviruses have been associated with the illness.
- Enterovirus 71 has also been associated with hand, foot, and mouth disease and outbreaks of this disease.
Hand, foot, and mouth disease is often confused with foot-and-mouth disease (also called hoof-and-mouth disease), a disease of cattle, sheep, and swine. However, the two diseases are caused by different viruses and are not related. Humans do not get the animal disease, and animals do not get the human disease. For more information, see the U.S. Department of Agriculture National Agricultural Library, Foot-and-Mouth Disease.
