What is hand, foot and mouth disease?

Hand, foot and mouth disease is an illness caused by a very contagious virus that can be passed along before a person is aware he or she is infected.

Is hand, foot and mouth disease contagious?

Be aware that hand, foot and mouth disease is easily transmitted from person to person. But just how is hand, foot and mouth disease spread? It can be transmitted in several ways, according to the Cleveland Clinic:

• Droplets from an infected person coughing or sneezing.
• Direct contact with blisters.
• Shared items, like utensils, towels, clothing, surfaces and toys.
• Through feces (stool, or poop). Be sure to wash your hands right away if you’re changing diapers, pull-ups or you otherwise come into contact with an infected person’s stool.

What causes hand, foot and mouth disease?

Two families of viruses cause hand, foot and mouth disease, according to the Mayo Clinic.

“Hand-foot-and-mouth disease is caused by human enteroviruses and coxsackieviruses.” wrote a team headed by Dr. Aaron Saguil, an associate dean at Uniformed Services University of the Health Sciences, in American Family Physician:

• Most people get this virus through the mouth.
• It is common among day care centers and preschools as small children need frequent diaper changes and tend to put their fingers in their mouths.
• The virus can stay on surfaces such as doorknobs and toys for a long time.
• People are most contagious before they realize they are infected.
