Worse news : Hand-foot-and-mouth disease

Hand-foot-and-mouth disease is a mild, contagious viral infection common in young children. 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.


Causes

The most common cause of hand-foot-and-mouth disease is infection due to 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 nose and throat discharges, saliva, fluid from blisters, or the stool of someone with the infection. The virus can also spread through a mist of fluid sprayed into the air when someone coughs or sneezes.

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.

Prevention

• 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 (60 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. Be a positive role model by showing 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 or school until fever is gone and mouth sores have healed. If you have the illness, stay home from work.
