Hand, foot and mouth disease (HFMD) is a common childhood infectious disease that can be caused by a variety of enteroviruses, predominantly in preschool children, and is generally susceptible to infants under three years of age. Among them, EV71 is one of the important pathogens causing hand-foot-and-mouth disease.

Hand-foot-mouth disease virus is highly likely to undergo partial variation. Symptoms are extremely atypical after the illness. Some children may not show high fever even if they are sick.
