As soon as the weather turns cooler in autumn and winter, parents with babies at home will be worried again, because autumn and winter are not only the high time for colds and flu, but also a lot of children will develop gastroenteritis, especially in childcare institutions, where many children may vomit, have fever and diarrhea together and get hit collectively. Today we will talk about diarrhea in the autumn and winter season. 1, the culprit of diarrhea In the fall, most of the etiology of diarrhea is viral, caused by bacteria, enteritis only accounts for a small percentage, bacterial enteritis is characterized by mucus and blood stools. Generally speaking, viral gastroenteritis will have varying degrees of fever, vomiting and watery stools, stools without mucus and blood, and older children will complain of abdominal pain. The typical rotavirus diarrhea is seen in infants and children aged 6-24 months, with an incubation period of 1-3 days, followed by vomiting and fever for 1-2 days, and then more severe diarrhea with watery or egg-soup-like stools, which can occur up to 10 times a day for 5-7 days. Therefore, dehydration and electrolyte disorders are likely to occur, and very few children can have convulsions. And norovirus is characterized by strong contagiousness, easy to focus on outbreaks in early childhood care institutions and schools. Norovirus enteritis can occur at any age, the symptoms of vomiting is the most prominent, there can be fever, diarrhea is generally not very serious, the course of the disease is short, more in 2-3 days to recover. 2, diarrhea how to treat and home care Viral gastroenteritis is usually self-limiting, there is no special treatment for the treatment, only symptomatic treatment, fever high with antipyretic drugs. Do not use antidiarrheal medication on your own, it may cause serious side effects. The most important thing is to hydrate and prevent dehydration. Parents can initially determine if dehydration has occurred by observing the child’s urine output and mental state. If the child has a dry mouth, sunken eye sockets, few tears when crying, depression, and a significant decrease in urine output (e.g., no urine for 4-6 hours), all may indicate that the child is dehydrated and needs to seek medical attention. If the doctor determines that only mild to moderate dehydration has occurred, only oral rehydration salts are needed to correct the dehydration as prescribed by the doctor. However, if severe dehydration and disturbance of electrolyte and acid-base balance have occurred, intravenous rehydration therapy is required based on the results of blood tests. In terms of diet, when a child vomits in the early stages of the disease, do not rush to drink water and rehydration salts immediately. Wait at least half an hour for the stomach to calm down a little before trying a small amount of water, and then gradually increase it. Fortunately, vomiting usually lasts for a short time, and diarrhea does not affect the child to continue eating, and additional oral supplementation of more water and electrolytes is needed to prevent dehydration of the body. 3, measures to prevent diarrhea usually diarrhea pathogenic microorganisms through contaminated food or toys, through the hands entrance, therefore, hand washing is the most simple and effective preventive measures, teaching children to thoroughly clean their hands with soap and warm water before meals, after the stool can greatly reduce the chances of infection. Parents also need to wash their hands frequently, especially after diaper changes and before handling food. Also, make sure that the food served to your child is safe and cooked.
