Those children who need fever reduction will not burn their brains out In the latest guidelines of the American Academy of Pediatrics on fever reduction, the point repeatedly emphasized is that unless it is ultra-high fever (greater than or equal to 41°C), fever is not harmful to the child, but rather beneficial. Fever with a clear cause, such as a bacterial infection, can be treated with anti-infective therapy to address the cause. Fever is good for boosting the child’s immune system and for fighting infections, unless it causes significant discomfort and does not require fever reduction. The goal of treating fever is to improve the child’s comfort rather than to reduce the fever. However, the child’s comfort level is difficult to measure with objective indicators. The consensus of American experts is that above 39 degrees (Chinese guidelines are above 38.5 degrees) the child will be more uncomfortable. Except for some children with genetic metabolic diseases, cardiopulmonary diseases, epilepsy and other diseases, children without obvious discomfort and without underlying diseases do not need to have their fever reduced until they are below 39 degrees and above 39 degrees when the child is obviously uncomfortable.
