Hand, foot and mouth disease (HFMD) is an infectious disease caused by enterovirus, which spreads very quickly and often affects children. In mild cases, the disease usually resolves on its own and does not significantly affect the child's health. However, in recent years, the disease has often had dangerous complications.

Hand, foot and mouth disease is an acute infectious disease that commonly occurs in children under 10 years of age, especially those aged 3-5. Symptoms include fever, sore throat and a rash with blisters on the hands, feet and mouth that often progresses to ulcers. Lesions can be found on the tongue, gums and inside the cheeks.
