Due to the extensive media coverage of HFMD in recent years, especially the fatal cases, parents have become fearful of the disease. To answer this question, further understanding of HFMD is needed. Hand, foot and mouth disease is caused by a variety of viral infections, because the performance of these viral infections are similar, will appear on the hands and feet blister rash and mouth ulcers, so collectively referred to as hand, foot and mouth disease. The most important feature of HFMD is that it is highly contagious and usually infects only children, but is rare in adults. Therefore, teachers in kindergartens, schools and other places where children gather are very vigilant, and children enrolled in school are checked daily during the epidemic of this disease. Hand, foot and mouth disease can be divided into three types: light, medium and heavy, of which light patients account for more than 80%, these children are not at risk, oral antiviral Chinese medicine can be cured within a week. Children with moderate type have a certain risk of becoming heavy, but they do not necessarily need to be hospitalized, they can be treated by outpatient infusion, and the fever will usually subside within three days. The severe form is rare, less than one in 10,000, but it can cause severe myocarditis, which is life-threatening and must be treated in hospital. Parents need not worry excessively when their child has HFMD, and promptly go to the hospital. As long as the doctor determines that the child is not heavy, he or she can be treated with peace of mind in the outpatient clinic and will surely be cured within a week. In addition, it is important to pay attention to isolation from other children in the family to prevent infection. Children with HFMD should eat a light diet, avoid frying and other foods that are hot and poisonous in Chinese medicine, drink more water, take rest and avoid fatigue.
