Hand, Foot and Mouth Disease

Hand, Foot & Mouth Disease is present all year round in Singapore with seasonal outbreaks every year. Outbreaks do occur in childcare centres, kindergartens and schools. Although usually a mild disease, it has been associated with fatalities usually due to complications involving the heart and nervous system (e.g. encephalitis).

Hand, Foot & Mouth Disease (HFMD) is caused by certain viruses. Among them, it is the EV71 virus that can give rise to serious complications.

HFMD became legally notifiable on 1 October 2000.

How it is Spread

HFMD is spread from person to person by direct contact with the nasal discharge, saliva, faeces and fluid from the rash of an infected person. Both adults and children can be affected, but young children below five years of age are particularly susceptible.

Signs and Symptoms

A child with HFMD may suffer from some of the following symptoms:

  • Fever

  • Sore throat

  • Ulcers in the throat, mouth and tongue

  • Headache

  • Rash with vesicles (small blisters 3-7 mm) on hands, feet and diaper area.

    The vesicles are typically on the palm side of the hands, the sole side of the feet and very characteristic in appearance. The rash may also be present on the buttocks, arms and legs.

  • Loss of appetite

  • Vomiting and/or diarrhoea

Complications

Severe ulcers in the mouth can be very painful and this may interfere with intake of food and drink resulting in dehydration. Dehydration may also be caused by persistent vomiting/diarrhoea coupled with a reduced fluid intake.

Complications such as brain, lung or heart infections may occur occasionally, usually due to the EV 71 virus and can be serious. Some signs and symptoms of complications include:

  • Severe headache, giddiness and neck stiffness

  • Disorientation, drowsiness and/or irritability

  • Fits

  • Breathlessness or turning blue

Screening and Diagnosis

Laboratory testing is available to isolate and identify the causative agent. However, testing is usually not necessary as diagnosis of HFMD is typically based on clinical grounds.

Treatment

There is no specific treatment for the infection other than symptomatic relief of symptoms. Treatment with antibiotics is not effective and is not indicated. If you suspect your child has HFMD, please bring him/her to see the family doctor.

Ease your child’s discomfort and help your child recover by:

  • Encouraging your child to drink plenty of fluids

  • Changing to a soft diet (e.g. porridge, pureed fruit) if the mouth ulcers are a problem

  • Giving medications as prescribed by the doctor, e.g. paracetamol syrup to relieve fever and pain

  • Ensuring your child gets plenty of rest by keeping him/her at home

Keeping Others Safe

If your child has HFMD, please help to prevent the spread of HFMD to others by:

  • Keeping him home from school, kindergarten or childcare centre.

  • Keeping him away from all public places including restaurants, playgrounds and shopping centres.

  • Looking out for signs and symptoms in other family members, both children and the adults.

  • Keeping his toys, books, eating utensils, towels and clothes separate from others.

  • Informing the school, kindergarten or childcare centre as soon as possible. They can monitor other children closely and take additional precautions to prevent the spread of HFMD.

  • Keeping him at home until all the blisters have dried up and he has fully recovered, after the expiry of the medical certificate (MC) given by the family doctor.

Prevention

Advice for Parents

Help protect your children from HFMD. Teach them good hygiene practices like:

  • Washing your hands with soap before eating and after going to the toilet.

  • Covering your mouth and nose when coughing or sneezing.

  • Not sharing eating utensils.

  • Ensuring that toys or appliances that are contaminated by nasal or oral secretions are cleaned thoroughly before they are used again.

  • Putting on a face mask when feeling unwell.

In addition, do follow these four steps before sending your child to the childcare centre every day.

  1. Take your child’s temperature (either orally or via the ear)

  2. Look for mouth ulcers.

    Ask your child to open his mouth and say “Ah”. Shine a torch in the mouth and look for ulcers on the tongue, inner sides of the mouth and on the lips.

  3. Look for blisters on the hands.

    Ask your child to hold out both hands and show his/her palms. Look for small pinkish/reddish bumps or tiny blisters with fluids. Then check for the same on the back of the hands.

  4. Look for blisters on the feet.

    Check for bumps/blisters on the upper part of the feet first then the soles.

If you suspect any of the above, DO NOT send your child to the centre. Take him/her to a family doctor for a thorough examination. If your child is diagnosed with HFMD, please keep him/her at home until fully recovered. Your child should return to the centre only after the expiry of the MC given by the family doctor when he/she is well.
