Hand, Foot, and Mouth Disease patients often experience high fever, with temperatures ranging from 38℃ to 40℃, lasting for 4 to 7 days.

This type of rash can also appear on the child’s buttocks and around the anus. Clinically, the characteristic of the disease is the appearance of blisters on the hands, feet, and mouth.
