Hand-foot-mouth disease

Toggle: English / Spanish


Hand-foot-mouth disease is a common viral infection that most often begins in the throat.

Alternative Names

Coxsackievirus infection; HFM disease


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:

  • A person with the infection sneezes, coughs, or blows their nose near you.
  • You touch your nose, eyes, or mouth after you have touched something contaminated by the virus, such as a toy or doorknob.
  • You touch stools or fluid from the blisters of an infected person.

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:

  • Fever
  • Headache
  • Loss of appetite
  • Rash with very small blisters on the hands, feet, and diaper area that may be tender or painful when pressed
  • Sore throat
  • Ulcers in the throat (including tonsils), mouth, and tongue

Exams and Tests

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:

  • Over-the-counter medicines, such as acetaminophen (Tylenol) or ibuprofen can be used to treat fever. Aspirin should not be given for viral illnesses in children under age 18.
  • Salt water mouth rinses (1/2 teaspoon of salt to 1 glass of warm water) may be soothing.
  • Drink plenty of fluids. You need extra fluid when you have a fever. The best fluids are cold milk products. DO NOT drink juice or soda because their acid content causes burning pain in the ulcers.

Outlook (Prognosis)

Complete recovery occurs in 5 to 7 days.

Possible Complications

Possible complications that may result from HFMD include:

When to Contact a Medical Professional

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:

  • Medicine does not lower a high fever
  • Signs of dehydration occur, such as dry skin and mucus membranes, weight loss, irritability, decreased alertness, decreased or dark urine


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.
