In recent times, diseases caused by enterovirus 71 infections have occurred in some areas of Fuyang City, Anhui Province, with the onset mainly in children. In order to do a good job of prevention of the disease and protect children’s health, the city has prepared scientific prevention and control knowledge materials for enterovirus 71 infectious diseases to effectively prevent children from getting sick from the infection. A. What is enterovirus 71 infection? Enterovirus 71 is a type of human enterovirus, referred to as EV71, which often causes childhood hand, foot and mouth disease, viral pharyngitis, pulmonary edema, viral encephalitis and other diseases, collectively known as enterovirus 71 infection. The disease occurs mostly in children, especially in infants and young children under the age of 3 years, and a few are sicker and can even cause death. The disease can occur throughout the year, but is common from April to September. What are the manifestations of children with enterovirus 71 infection? Most children have fever, usually around 38°C. The fever is accompanied by a rash in the mouth, hands, feet and buttocks, or ulcers in the mouth and a mucous membrane rash. Some patients have cough and other cold-like manifestations in the early stage. After 1-2 days of fever, a rash starts to appear, and some children also develop oral ulcers. The rash is not itchy and usually appears on the palms of the hands and soles of the feet, but can also appear on the buttocks. Oral ulcers usually appear on the tongue and the oral mucosa of the inner cheeks. Some children do not develop a fever, but only a rash or herpetic pharyngitis, which is mild. Most children recover within a week when their temperature drops and the rash subsides. A small number of children, especially infants and children under 3 years of age, may develop serious complications. Most of these patients have persistent high fever and rapid disease development, and most of them develop serious complications of central nervous system, respiratory system and circulatory system within 3-5 days after the onset of the disease, and can cause death, which is mainly caused by cerebral edema, brain herniation, central respiratory and circulatory failure. Third, what are the modes of transmission of enterovirus 71 infection? The disease is transmitted in various ways, mainly through close contact with the crowd, airborne droplet transmission, water and food transmission, etc. Children are infected through contact with virus-contaminated hands, towels, handkerchiefs, tooth cups, toys, eating utensils, milk utensils, bedding, underwear, etc. 2, the virus in the patient’s throat secretions and saliva can be transmitted through the air, so close contact with sick children can cause infection. 3. Infection can also occur when drinking or eating water or food contaminated with virus. Fourth, how can you effectively prevent your child from infection? 1.Good hygiene habits are very important to prevent infection. Parents should educate their children to strengthen personal hygiene, wash their hands before and after meals, brush their teeth, rinse their mouths and bathe regularly. To drink boiled water, do not drink raw water, do not eat cold food, leftovers should be completely heated before consumption. 2, for infants and young children under 3 years old, parents should take care of their children, do not let them crawl and play on the ground, do not feed them with their own chewed food, and should also pay attention to good personal hygiene. Parents should take their children to crowded public places as little as possible, especially try to avoid contact with other children with fever and rash diseases to reduce the chance of being infected. 4, to strengthen the child’s nutrition, pay attention to let the child rest well, in order to enhance the resistance to disease. 5. Pay attention to your child’s health condition. Once you find that your child has fever and rash, you should take your child to a regular hospital for medical treatment as soon as possible. If the doctor recommends hospitalization, you should actively cooperate. If your child is a kindergartener or school student, you should also tell the teacher as soon as possible. Do not rush to kindergarten or school before the child is completely cured to prevent transmission to other children. 6, pay attention to the cleanliness of the family indoor and outdoor, often clean up garbage and feces, strengthen the windows and ventilation, clothes, bedding should be exposed to the sun. Poultry and livestock should be kept in captivity, avoid mixing people and livestock in one place, especially to reduce the direct contact between children and poultry and livestock.
