Hand-foot-mouth disease is a common viral infection that most often begins in the throat.
Hand-foot-mouth disease (HFMD) is most commonly caused by a virus called coxsackievirus A16.
Children under age 10 are most often affected. Teens and adults can sometimes get the infection. HFMD usually occurs in the summer and early fall.
The virus can spread from person-to-person through tiny, air droplets that are released when the sick person sneezes, coughs, or blows their nose. You can catch hand-foot-mouth disease if:
The virus is most easily spread the first week a person has the disease.
The time between contact with the virus and the start of symptoms is about 3 to 7 days. Symptoms include:
A history of recent illness and a physical exam that shows a rash on the hands and feet can usually diagnose the disease.
There is no specific treatment for the infection other than symptom relief.
Antibiotics do not work because the infection is caused by a virus. (Antibiotics treat infections caused by bacteria, not viruses.) To relieve symptoms, the following home care can be used:
Complete recovery occurs in 5 to 7 days.
Possible complications that may result from HFMD include:
Call your health care provider if there are signs of complications, such as pain in the neck or arms and legs. Emergency symptoms include convulsions.
You should also call if:
Avoid contact with people with HFMD. Wash your hands well and often, especially if you are in contact with people who are sick. Also teach children to wash their hands well and often.
