Useful Information about Hand-Foot-Mouth
Definition
Hand-foot-and-mouth
disease — a mild, contagious viral infection common in young children — is
characterized by sores in the mouth and a rash on the hands and feet.
Hand-foot-and-mouth disease is most commonly caused by a coxsackievirus.
There's
no specific treatment for hand-foot-and-mouth disease. You can reduce your risk
of infection from hand-foot-and-mouth disease by practicing good hygiene, such
as washing your hands often and thoroughly.
Symptoms
Hand-foot-and-mouth disease may cause some or all of the
following signs and symptoms:
·
Fever
·
Sore
throat
·
Feeling
of being unwell (malaise)
·
Painful,
red, blister-like lesions on the tongue, gums and inside of the cheeks
·
A
red rash, without itching but sometimes with blistering, on the palms, soles
and sometimes the buttocks
·
Irritability
in infants and toddlers
·
Loss
of appetite
The
usual period from initial infection to the onset of signs and symptoms
(incubation period) is three to seven days. A fever is often the first sign of
hand-foot-and-mouth disease, followed by a sore throat and sometimes a poor
appetite and malaise. One or two days after the fever begins, painful sores may
develop in the mouth or throat. A rash on the hands and feet and possibly on
the buttocks can follow within one or two days.
When to see a doctor
Hand-foot-and-mouth disease is usually a minor illness causing only a few days of fever and relatively mild signs and symptoms. Contact your doctor, however, if mouth sores or a sore throat keep your child from drinking fluids. Contact your doctor also if after a few days, your child's signs and symptoms worsen.

Causes
The most
common cause of hand-foot-and-mouth disease is infection with the
coxsackievirus A16. The coxsackievirus belongs to a group of viruses called
nonpolio enteroviruses. Other enteroviruses sometimes cause hand-foot-and-mouth
disease.
Oral
ingestion is the main source of coxsackievirus infection and
hand-foot-and-mouth disease. The illness spreads by person-to-person contact
with an infected person's:
·
Nasal
secretions or throat discharge
·
Saliva
·
Fluid
from blisters
·
Stool
·
Respiratory
droplets sprayed into the air after a cough or sneeze
Common
in child care setting
Hand-foot-and-mouth disease is most common in children in child care settings because of frequent diaper changes and potty training, and because little children often put their hands in their mouths.

Although
your child is most contagious with hand-foot-and-mouth disease during the first
week of the illness, the virus can remain in his or her body for weeks after
the signs and symptoms are gone. That means your child still can infect others.
Some
people, particularly adults, can pass the virus without showing any signs or
symptoms of the disease.
Outbreaks
of the disease are more common in summer and autumn in the United States
and other temperate climates. In tropical climates, outbreaks occur year-round.
Different
from foot-and-mouth disease
Hand-foot-and-mouth disease isn't related to foot-and-mouth disease (sometimes called hoof-and-mouth disease), which is an infectious viral disease found in farm animals. You can't contract hand-foot-and-mouth disease from pets or other animals, and you can't transmit it to them.

Risk factors
Hand-foot-and-mouth
disease primarily affects children younger than age 10. Children in child care
centers are especially susceptible to outbreaks of hand-foot-and-mouth disease
because the infection spreads by person-to-person contact, and young children are
the most susceptible.
Children
usually develop immunity to hand-foot-and-mouth disease as they get older by
building antibodies after exposure to the virus that causes the disease.
However, it's possible for adolescents and adults to get the disease.
Complications
The most
common complication of hand-foot-and-mouth disease is dehydration. The illness
can cause sores in the mouth and throat, making swallowing painful and
difficult. Watch closely to make sure your child frequently sips fluid during
the course of the illness. If dehydration is severe, intravenous (IV) fluids
may be necessary.
Hand-foot-and-mouth
disease is usually a minor illness causing only a few days of fever and
relatively mild signs and symptoms. However, a rare and sometimes serious form
of the coxsackievirus can involve the brain and cause other complications:
·
Viral meningitis. This is an infection and
inflammation of the membranes (meninges) and cerebrospinal fluid surrounding
the brain and spinal cord. Viral meningitis is usually mild and often clears on
its own.
·
Encephalitis. This severe and potentially
life-threatening disease involves brain inflammation caused by a virus.
Encephalitis is rare.
To help lessen discomfort,
doctors often recommend:
·
Getting
rest
·
Drinking
fluids — milk-based fluids may be easier to tolerate than acidic liquids, such
as juice or soda
·
Taking
over-the-counter pain relievers other than aspirin, such as acetaminophen
(Tylenol, others) or ibuprofen (Advil, Motrin, others), if needed, but they're
not necessary for low-grade fevers
·
Using
mouthwash or oral spray to numb pain
Treatments and drugs
There's
no specific treatment for hand-foot-and-mouth disease. Signs and symptoms of
hand-foot-and-mouth disease usually clear up in seven to 10 days.
A
topical oral anesthetic may help relieve the pain of mouth sores.
Over-the-counter pain medications other than aspirin, such as acetaminophen
(Tylenol, others) or ibuprofen (Advil, Motrin, others), may help relieve
general discomfort.
Lifestyle and home remedies
Certain
foods and beverages may irritate blisters on the tongue or in the mouth or
throat. Try these tips to help make blister soreness less bothersome and eating
and drinking more tolerable:
·
Suck
on ice pops or ice chips
·
Eat
ice cream or sherbet
·
Drink
cold beverages, such as milk or ice water
·
Avoid
acidic foods and beverages, such as citrus fruits, fruit drinks and soda
·
Avoid
salty or spicy foods
·
Eat
soft foods that don't require much chewing
·
Rinse
your mouth with warm water after meals
If your
child is able to rinse without swallowing, swishing the inside of his or her
mouth with warm salt water may be soothing. Mix 1/2 teaspoon (2.5 milliliters)
of salt with 1 cup (237 milliliters) of warm water. Have your child rinse with
this solution several times a day, or as often as needed to help reduce the
pain and inflammation of mouth and throat sores caused by hand-foot-and-mouth
disease.
Prevention
Certain
precautions can help to reduce the risk of infection with hand-foot-and-mouth
disease:
·
Wash hands carefully. Be sure to wash your hands
frequently and thoroughly, especially after using the toilet or changing a
diaper, and before preparing food and eating. When soap and water aren't
available, use hand wipes or gels treated with germ-killing alcohol.
·
Disinfect common areas. Get in the habit of cleaning
high-traffic areas and surfaces first with soap and water, then with a diluted
solution of chlorine bleach, approximately 1/4 cup (59 milliliters) of bleach
to 1 gallon (3.79 liters) of water. Child care centers should follow a strict
schedule of cleaning and disinfecting all common areas, including shared items
such as toys, as the virus can live on these objects for days. Clean your
baby's pacifiers often.
·
Teach good hygiene. Show your children how to
practice good hygiene and how to keep themselves clean. Explain to them why
it's best not to put their fingers, hands or any other objects in their mouths.
·
Isolate contagious people. Because hand-foot-and-mouth
disease is highly contagious, people with the illness should limit their
exposure to others while they have active signs and symptoms. Keep children
with hand-foot-and-mouth disease out of child care, church or school until fever is
gone and mouth sores have healed. If you have the illness, stay home from work and church.
