What are the conditions of HFMD? What can be done to prevent it?

Hand-and-mouth disease is more common in children under 5 years of age, and the elderly can also be infected, but the incidence is small. Usually the precursor to this disease is fever, which is a rash on the extremities. It is caused by enterovirus type 71 after infection, there is no obvious prodrome or only mild malaise, most children have fever symptoms one to two days before the onset of the disease or at the same time as the onset of the disease, and the body temperature is mostly around 38.

Subsequently, a rash appears on the child's hands, feet, oral mucosa, and buttocks, and the rash is usually not painful, itchy, crusted, or scarred; Because canker sores can be painful, children tend to salivate and refuse to eat, and the rash usually resolves on its own within a week, while the body temperature drops. Enterovirus 71 infection is often accompanied by more serious comorbidities, such as pulmonary edema, aseptic meningitis, fulminant myocarditis, etc., most of these children continue to have high fever, the disease develops rapidly, and it is more common in children under 2 years old, and serious complications of the central nervous system, respiratory system, and circulatory system appear within 3 to 5 days after the onset of the disease, and can cause death. The disease is mainly transmitted through food, nose and mouth droplets, and contact, so prevention should be done mainly to:
