What are the early symptoms of hand, foot, and mouth disease?

Patient's question:

Oral ulcer. Diarrhea. Small red spots on the feet for 10 years. June 30th, how to treat it well

Doctor's answer:

Hand, foot, and mouth disease is an infectious disease caused by enteroviruses. It primarily affects children under the age of 5 and can lead to the appearance of blisters on the hands, feet, mouth, and other parts. In some cases, it may cause complications such as myocarditis, pulmonary edema, and aseptic meningitis.
Advice: During the epidemic season, classrooms and dormitories should be well-ventilated. Workers should wear gloves when cleaning or disinfecting (especially when cleaning toilets). Wash hands immediately after cleaning. Medical staff should thoroughly wash or disinfect their hands after treating and caring for each patient.
