Hand, foot and mouth disease (HFMD) is a highly contagious illness occurring worldwide, caused by several enteroviruses, including coxsackievirus A16 and enterovirus 71. In most cases, HFMD follows a benign and self-limiting course. However, severe neurological complications (such as meningoencephalitis) and even fatal outcomes have been repeatedly reported in Southeast Asia.
