Hand, foot and mouth disease - including symptoms, treatment and prevention
Hand, foot and mouth disease is a viral infection usually caused by the Coxsackie virus group A. However, sometimes it is caused by other viruses such as an echovirus or an enterovirus. Enterovirus 71 (EV71) can cause hand, foot and mouth disease as well as more serious illness, particularly in children.
How hand, foot and mouth disease is spread
The virus can spread from an infected person by:
close contact with the fluid in the blisters
coughing and sneezing
contact with faeces
contact with contaminated objects or surfaces.
Signs and symptoms of hand, foot and mouth disease
Symptoms may include:
loss of appetite
blisters in the mouth and on the hands and feet (see image)
a sore mouth for a few days before the ulcers or blisters appear.
Affected young children may refuse to eat or drink.

Diagnosis of hand, foot and mouth disease
Diagnosis is usually made when seeing a doctor. Laboratory tests are not usually required.

3 to 5 days.
(time during which an infected person can infect others)
The blisters are infectious as long as they contain fluid. The faeces can remain infectious for several weeks.
Treatment for hand, foot and mouth disease
Usually no specific treatment is required. Use of paracetamol for the fever and any discomfort may be indicated. Aspirin should not be given to children under 12 years of age unless specifically recommended by a doctor.
