What causes hand, foot, and mouth disease?

Patient's question:

Red spots on the hand and foot in March 2010: Previous treatment and effectiveness: Hospitalized for a week, hoping to understand more about hand, foot, and mouth disease technology

Doctor's answer:

The disease is an infectious illness caused by enteroviruses, which can lead to blisters on the hands, feet, and mouth. The vesicles on children's hands contain neutrophil and eosinophil fragments, with intercellular and intracellular edema in the surrounding epidermis. The dermis beneath the vesicles shows a mixed infiltration of various white blood cells, which is the main cause of vesicles on children's hands and feet. Mild cases do not require hospitalization and can be treated at home with rest to prevent cross-infection.
Personal advice: Considering the child is only 17 months old and their digestive system is not yet mature, oral medication is not recommended. After full recovery, recurrent episodes are directly related to the child's constitution. As long as the child pays attention to details in daily life, they will recover.
