Overview

Hand-foot-and-mouth disease is an illness caused by a virus. It causes a rash that appears on the palms of the hands and soles of the feet. Small blisters also occur in the mouth, usually at the back of the throat. The rash may also appear in the diaper area, and on the legs and arms.

Causes

Hand-foot-and-mouth disease is caused by a virus. The most common viruses that cause it include:

  • Coxsackievirus A16
  • Enterovirus A71

The virus is usually spread through fecal-oral transmission. This is often because of not washing hands properly, particularly after changing diapers or using the bathroom. Handwashing is key to help prevent the spread of the disease.

Risk Factors

This disease is very common in children. A child under the age of 10 is most at risk.

Symptoms

Symptoms can occur a bit differently in each child. They can include:

  • Blisters in the mouth, usually near the throat and tonsils
  • Small blisters on the palms of the hands or soles of the feet, or both
  • Small blisters in the diaper area
  • Rash on the arms and legs
  • Fever
  • Lack of appetite
  • Generally not feeling well

The symptoms of hand-foot-and-mouth disease are usually unique. But they can be like other health conditions. Make sure your child sees his or her healthcare provider for a diagnosis.

Diagnosis

The healthcare provider will ask about your child’s symptoms and health history. He or she will give your child a physical exam. The physical exam will include looking at the rash. The rash is unique to hand-foot-and-mouth disease. The rash may be enough to diagnose your child. In some cases, your child may also have a throat culture or stool sample sent to a lab for testing.

Treatment

Treatment will depend on your child’s symptoms, age, and general health. It will also depend on how severe the condition is. Antibiotics are not used to treat this illness.

The goal of treatment is to help reduce symptoms. Symptoms may last up to a week. Treatment may include:

  • Making sure your child drinks plenty of cold fluids to help soothe mouth pain
  • Giving acetaminophen or ibuprofen for fever and discomfort
  • Using a mouth rinse or spray that contains a pain reliever to help lessen the mouth pain. Use this only if your child's healthcare provider says it’s OK to do so. Don't use regular mouthwash, because it may hurt.

Talk with your healthcare provider about the risks, benefits, and possible side effects of all medicines. Don't give ibuprofen to a child younger than 6 months old, unless your healthcare provider tells you to. Don't give aspirin to children. Aspirin can cause a serious health condition called Reye syndrome.

Prevention

Good handwashing is important to stop the disease from being spread to other children. To help prevent the spread of the illness to others:

  • Wash your hands before and after caring for your child. Use soap and warm water and scrub for at least 20 seconds. Rinse well and air dry or use a clean towel.
  • Make sure your child washes his or her hands often.
  • Make sure your childcare center encourages handwashing.

Also make sure to:

  • Clean contaminated surfaces with a disinfectant.
  • Stay away from infected people. An infected person can still transmit viruses for 1 to 2 weeks after he or she no longer has symptoms.

When to Call a Healthcare Provider

Call the healthcare provider if your child has:

  • Symptoms that don’t get better, or get worse
  • New symptoms
