Hand, foot and mouth disease

Hand, foot and mouth disease (HFMD) is caused by a number of enteroviruses in the family Picornaviridae. The most common cause is the Coxsackie A virus. HFMD is not to be confused with Hoof-and-mouth disease, which is a disease affecting sheep, cattle and swine, and which is unrelated to HFMD (but also caused by a member of the Picornaviridae family).

HFMD usually affects infants and children, and is quite common. It is moderately contagious and is spread through direct contact with the mucus or feces of an infected person. It typically occurs in small epidemics in nursery schools or kindergartens, usually during the summer and autumn months.

Symptoms

Symptoms of HFMD include:

• low grade fever
• malaise
• abdominal pain
• upper respiratory symptoms
• painful oral lesions starting as pink macules and papules that progress to vesicles with surrounding erythema
• sores with blisters on palms of hands and soles of feet
• mouth ulcers
• sores or blisters may be present on the buttocks of small children and infants

Not all symptoms may be present.

Treatment

There is no specific treatment for hand, foot and mouth disease. Individual symptoms, such as fever, lameness and pain from the sores, may be eased with the use of medication. HFMD is a viral disease that has to run its course; many doctors do not issue medicine for this illness, unless the infection is severe. It is usually in the affected child's best interest to be kept home until the infection clears. Fever reducers will help to control high temperatures. Luke-warm baths will also help bring temperature down.

Only a very small minority require hospital admission, mainly as a result of neurological complications (encephalitis, meningitis or acute flaccid paralysis) or pulmonary edema/pulmonary hemorrhage.
