Pediatric hand, foot, and mouth disease is an infectious disease caused by an enterovirus infection. Viral infections are characterized as self-limiting diseases that can heal without medication if the child has good immune function and the symptoms are not severe. For example, in older children, there is no fever and no painful herpes in the throat or cheeks, but only a rash on the hands and feet after contracting HFMD. At this time, you can pay attention to the child’s diet by giving him or her light, easily digestible food, avoiding oral fish, shrimp, eggs, beef, mutton and other hairy substances to aggravate the child’s condition. Also give the child more water to help the recovery of the disease. Adequate sleep daily, the disease can usually heal itself in about 7-10 days. For children with poor immunity at a young age, if they have fever or poor feeding, they need to be treated by medication intervention.
