What causes hand, foot, and mouth disease?
HFMD is caused by several members of the enterovirus family of viruses. The most common cause is Coxsackievirus A-16; less frequently
enterovirus 71 is the infectious agent. The clinical manifestations of routine HFMD are the same regardless of the responsible virus. However, patients infected with enterovirus 71 are more likely to experience rare complications (for example, viral meningitis or cardiac muscle involvement).
