Many parents believe that spring and autumn are the seasons when pediatric hand, foot and mouth disease is common, but recently there has been an increase in the number of children suffering from hand, foot and mouth disease in the pediatric clinics of some hospitals compared to previous years, which has caused concern among parents. In this regard, parents are reminded that children are also susceptible to HFMD in summer and parents need to be more vigilant. Hand, foot and mouth disease mostly occurs in infants and young children under 4 years old, the onset of the disease is urgent, fever or even high fever, the oral mucosa appears scattered herpes, the size of a grain of rice, or the palms of the hands or feet appear rice-sized herpes, but also in the buttocks or knees. The herpes are observed to be surrounded by an inflammatory redness, with less fluid in the herpes and significant pain. Some children may present with cough, runny nose, loss of appetite, nausea, vomiting, and headache. HFMD is a pediatric infectious disease with many routes of transmission. Parents should always remind and help their children to wash their hands regularly, especially after meals and going out, and their children’s bedding should be washed and changed frequently and the room should be ventilated. In summer, reduce the chances of children entering public places, and disinfect dishes, toys and other children’s products. Pay special attention to your child’s diet and get up early. Make sure the food you eat is fresh, clean and nutritious, and send your child to the doctor as soon as he or she has diarrhea to avoid hand, foot and mouth disease caused by an intestinal virus. Once a case of pediatric HFMD is found in a kindergarten, closely observe the state of your child, thoroughly disinfect the child’s belongings in the kindergarten, and have your child take antiviral medication for prevention. When your child has the initial symptoms of HFMD – cough, runny nose, drooling and other symptoms similar to upper respiratory tract infections – do not take medication without permission, but go to the hospital first to confirm the diagnosis, so as not to delay the treatment, because pediatric HFMD can easily lead to meningitis, encephalitis, encephalomyelitis, pulmonary edema, circulatory disorders, which can lead to death in critical conditions. How to prevent HFMD? To prevent HFMD, you should avoid contact between your child and affected children or people with suspicious symptoms, wash your hands before eating, do not use other people’s utensils or other household items, and go to densely populated public places as little as possible. If the child is infected, he or she should rest in bed, drink warm water when fever is present, eat a light and soft diet, and eat cold food when the child’s mouth hurts. Pay attention to the child’s hygiene, dispose of the stool immediately, disinfect the potty and clothes in time, protect the skin of hands and feet and the cleanliness of clothes and sheets to avoid contaminating the broken rash, wash the child’s hands regularly, and cut the nails short to prevent skin infection caused by scratching the rash.
