Is mouth hands and foot disease contagious?

Yes, hand, foot, and mouth disease (HFMD) is contagious. It is caused by a virus, usually coxsackievirus A16 or enterovirus 71, and spreads through contact with an infected person's saliva, mucus, or stool. People with HFMD are most contagious during the first week of illness, but they can spread the virus for several weeks. HFMD is most common in children under the age of five, but it can also occur in adults.
