Fever is the most common symptom in children, every parent will be anxious because of fever in children, in fact, in general, fever in children need not be anxious, the following article may be helpful to you. A. What are the common causes of fever in children? In fact, more than 90% of the causes of fever in children are caused by upper respiratory tract infections, which are usually called “colds”, including acute pharyngitis, acute rhinitis, acute tonsillitis, and so on. The “upper sensation” is commonly known as the “cold”. It is one of the most common diseases in children, and according to medical observation, a child often has several recurrent colds in a year, especially infants and preschoolers are prone to colds. The degree of severity of children’s colds varies greatly, and in mild cases, it is just a runny nose, nasal congestion, sneezing, and generally heals itself in 3 to 4 days. Sometimes it is accompanied by fever, sore throat, inflammation of tonsils and swollen lymph nodes, and the fever can last from 2-3 days to about 1 week. When children have a cold, they often have vomiting and diarrhea, and in severe cases, their body temperature can be as high as 39-40℃ or higher, accompanied by general symptoms such as chills, headache, general weakness, loss of appetite and sleep disturbance. In general, fever is the main symptom of pediatric cold. What are the pathogens (causes) that cause colds? The pathogens that cause colds are mainly viruses, which account for more than 95%. There are many types of viruses and they mutate very easily, so children are generally not immune to colds, and if they have a poor constitution and resistance, they are prone to recurring colds. Children with viral colds generally do not need to take antibiotics, as long as they take better care, rest properly, drink more water, and give them an easy-to-digest diet, they will soon recover. Do I need to see a doctor for fever? Many parents have experienced that when a child has a fever and goes to the hospital, there are two things the doctor wants to do: one is to check the blood and the other is to hang water. When the blood count (white blood cells) is high, the doctor says it is a bacterial infection and needs to be hooked up to water, but if it is low, it is a mixed bacterial and viral infection and needs to be hooked up to water. Is this really the case? This requires a reasonable analysis. In general, children with fever do not need to see a doctor within 3 days, if the fever is still bad after 3 days, there is no rush to see a doctor again. Fourth, what should I do if my child has a fever? Pediatric fever temperature 37.5℃-38℃ is low fever, 38℃-39℃ is medium fever, over 39℃ is high fever, and over 41℃ is super high fever.

When the body temperature reaches 39℃ or more, the fever should be reduced under the guidance of a doctor. Convulsions occur in 4% to 12% of children with high fever, and repeated attacks of convulsions may cause brain damage and may lead to other dangers. Therefore, children with a history or family history of febrile convulsions can be given appropriate fever-reducing medication at 38℃ when physical cooling is ineffective. V.
