Question
My son has been suffering from continuous low-grade fever for four days now. He has a cough with phlegm and also burps and has a runny nose. The fever has been persisting for several days, with the temperature reaching 38.5 degrees several times. After taking antipyretics, it dropped below 38 degrees. However, there are still high fever episodes. After visiting the hospital, the doctor diagnosed it as an upper respiratory infection and confirmed viral infection through urine tests. After taking medication for the first two days, the fever subsided, but on the third day after receiving an antibiotic injection, his temperature was still around 37.7 degrees at night. There was one instance where the temperature reached 38.5 degrees, and after taking antipyretics, it dropped to 37.5 degrees. In the morning, after taking several temperature readings, I found that it had risen to 38 degrees without taking any medication. After lunch and queuing up, I took the medicine, and his current temperature is below 37.5 degrees. I want to know if this will harm the brain?
Answer
There are many causes of fever, which can be categorized into infectious and non-infectious, with infectious causes being the most common, such as upper respiratory infections being a common cause. For fever, it is first necessary to determine the cause and treat it accordingly. High fever may trigger febrile seizures in children, so it is necessary to cool down, which can be done using both medication and physical methods of cooling down. The specific medication should be used under medical guidance.
