Hand-foot-and-mouth disease is a viral illness. It is characterized by shallow, painful ulcers in the mouth and red spots or blisters on the palms of the hands and soles of the feet. Hand-foot-and-mouth disease can be caused by a number of viruses, but most commonly is caused by Coxsackie A virus. It is not related to hoof and mouth disease in cattle. Cases of hand-foot-and-mouth disease occur most commonly during the warm-weather months (especially late summer and fall). There are at least 4 different strains of the virus that causes hand-foot-and-mouth disease. Although many children have this illness only once (and that illness gave your child immunity so that they would not have it again), it is possible to have the illness more than once.
Hand-foot-and-mouth disease begins 3-7 days after exposure to someone with the illness. The illness is highly contagious and spreads by contact with the mouth, saliva, and skin of an infected person. Children are more susceptible than adults. The illness can begin with 1-2 days of fever, sore mouth, decreased appetite, and decreased activity. Shallow ulcers with a red border then form in the mouth. They can occur anywhere within the mouth. These ulcers are often painful for 3-4 days and can remain for 7-10 days. Soon after the ulcers in the mouth form, about half of the children will develop occasionally painful (sometimes itchy) red spots or blisters on the hands and feet. These spots are usually small and fade without crusting over in 2-7 days. A few children will develop stomach pain, diarrhea, achy joints, swollen lymph glands at the neck, a dramatic decrease in activity, or red spots or blisters on areas other than the hands and feet. Most children will have only one case of hand-foot-and-mouth disease, but it is possible to have this disease more than once.
Complications to hand-foot-and-mouth disease are uncommon, but occasionally a child will become dehydrated if the painful mouth ulcers severely limit fluid intake.
Because the Coxsackie virus is spread by contact with mouth, hands, feet, and bowel movement from an affected child, limiting contact with these will limit the spread of the illness. Good hand washing is a must. Children at a sitter or in a daycare setting are very likely to have this illness sometime in the first 4 years of life.
The most contagious periods are just before and during the time of the mouth ulcers. Children should generally be kept home from daycare or school during those days in which they have a fever or painful ulcers in the mouth.
Technically, 80-90 % of the children with hand-foot-and-mouth are non-contagious after one week. The other 10-20 % may still be contagious for as long as 4 weeks. There is no way to determine who is contagious by examining them. This lingering contagious period for some of the children makes it easy for the illness to spread from a child with no symptoms to another child.
Hand-foot-and-mouth disease will run its course without special treatment. Because this illness is caused by a virus, antibiotics will not affect hand-foot-and-mouth disease. However, certain treatments can be helpful.
