Hand, Foot, and Mouth Disease is a common infectious disease caused by various enteroviruses, primarily affecting infants and young children, with a high susceptibility in children under 4 years old. It peaks during the transition from summer to autumn, with September being the peak month, so it is important to be vigilant. Most patients experience mild symptoms; when a baby has Hand, Foot, and Mouth Disease, they may cough, drool excessively, and have little appetite. The throat is also filled with many small blisters. The typical onset of the disease is a moderate fever (below 39℃), followed by sore throat and rashes or blisters on the hands, feet, and mouth.
