Whether or not a child can recover from HFMD depends on the child’s condition. Most children with mild cases can recover on their own, while a few children with severe cases need to undergo active treatment to cure the disease. HFMD is an acute febrile rash caused by enteroviruses. Most children have mild symptoms, such as maculopapular rash and herpes in the mouth and extremities, which can be cured within a week and have a good prognosis. A small number of severe patients may develop aseptic meningitis, brainstem encephalitis, encephalomyelitis, neurogenic pulmonary edema, cardiorespiratory failure and other severe manifestations, and often can not be self-healing. At the same time, the disease can develop rapidly and even lead to death, seriously threatening the life and health of children. If a child has hand, foot and mouth, it is recommended to go to the hospital in a timely manner, under the guidance of the doctor for professional diagnosis and treatment, to prevent delays in the condition, resulting in more serious consequences.
