Hand-foot-mouth disease
Coxsackievirus infection; HFM disease
Hand-foot-mouth disease is a common viral infection that most often begins in the throat.
Causes
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.
Symptoms
The time between contact with the virus and the start of symptoms is about 3 to 7 days. Symptoms include:
-
Fever

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.
Treatment
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 or 6 grams 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:
- Loss of body fluids (dehydration)
-
Seizures due to high fever (
febrile seizures
)
Febrile seizures
A febrile seizure is a convulsion in a child triggered by a fever.
