The illness is a mild infectious childhood illness caused by a number of different viruses, usually a strain of the Coxsackie virus, says pediatric nurse practitioner Catherine Quinn-Welsh, CNP.

“Like most viruses, it’s fairly contagious. So in a daycare or school setting it can spread very quickly,” she says. “It can spread quickly among family members too if they haven’t had it, and will often spread among the entire family.”

The illness gets its name from the blister-like rash that usually forms on the hands, feet, and mouth.

Hand, foot and mouth disease is very common. It usually affects infants and children under the age of 10. Because hand, foot, and mouth disease is infectious, it can sometimes make adolescents and adults sick, too.

Hand, foot and mouth disease is a completely different condition than foot-and-mouth disease. Foot-and-mouth disease is an illness that affects cattle, sheep and swine. The two diseases are unrelated and stem from different viruses.

Over-the-counter pain medications can help as well.

  • Washing your hands often, especially after changing diapers.
  • Disinfecting any contaminated surfaces with a water and bleach.
  • Washing your child’s clothing, bedding and any other soiled items.
  • If your child becomes infected, keeping him or her home from daycare, school or any other group activity for the first few days of the illness to prevent spread.
