Question
Is it normal for a child’s body temperature to fluctuate between morning and evening? If a child’s body temperature reaches about 37.5 degrees Celsius at noon without any fever symptoms, has undergone an EEG, myocardial enzymes, and fever tests with no abnormalities, and shows a positive adenovirus antibody in the respiratory four tests, what should be done if the body temperature remains unstable after 8 days of antiviral intravenous treatment? Is the child still suffering from viral infection, or is this a normal temperature fluctuation?
