There is no specific treatment for HFMD, and symptomatic treatment and care are the main focus. Therefore, when a child suffers from hand, foot and mouth disease, parents should cooperate with the doctor and do a good job of care. I. Disinfection and isolation First of all, the affected child should be isolated from healthy children. The affected child should stay at home until the fever, rash subsides and the blisters crust over. Usually 2 weeks of isolation is needed. Toys, dishes or other supplies used by the affected child should be thoroughly disinfected. Disinfection by soaking and boiling with chlorine solution is commonly used. Items that are not suitable for steaming or soaking can be exposed to sunlight. The feces of the child should be disinfected by chlorine disinfectant for 2 hours and then dumped. Keep indoor air circulation The air in the child’s room should be fresh and the temperature should be suitable, and windows should be opened regularly for ventilation. The amount of lactic acid should be calculated as 2ml per 10 square meters of room, added to an appropriate amount of water, heated and evaporated, so that the fine mist of lactic acid is dispersed in the air. Avoid too many people in the room, prohibit smoking and prevent air pollution to avoid secondary infection. Rest and diet The child should rest in bed and drink warm water within a week. Children with fever and oral cavity have poor appetite and are reluctant to eat, so the diet should be light, tasty and easy to digest, and some liquid food can be eaten when the oral cavity has erosion. Forbidden to eat cold, spicy, salty and other irritating food. The oral cavity should be kept clean to prevent bacterial secondary infections, and warm water should be used to rinse the mouth after each meal, and the oral cavity can be coated with montelukast, rehabilitative new, gentamycin, and cod liver oil to reduce pain and promote early healing of the crust. V. Rash care The child’s clothes and bedding should be clean, clothing should be wide, soft and often changed. The bed should be flat and dry. Cut the child’s nails short and wrap the child’s hands if necessary to prevent scratching the rash. Babies with rashes on the buttocks should be cleaned up at all times to keep the buttocks clean and dry. For ruptured herpes, apply 1% gentian violet or antibacterial ointment locally. If the body temperature exceeds 38.5℃, antipyretic agents can be taken under the guidance of the doctor. Seven, pay attention to the observation of changes in the condition Because the enterovirus that causes HFMD also has the characteristics of attacking the brain and heart, which can cause complications such as meningitis and cardiomyopathy, parents should closely observe the changes in the child’s condition, and should immediately go to the hospital when they find that the child has high fever, vomiting, poor mental health, easy to be frightened, difficulty in breathing, trembling and shaking of the limbs, unstable standing, shaking of objects, cold limbs and cold sweat.
