Health, you’re wrong. A 103 fever is extremely dangerous unless it immediately starts to go down.
It takes a 107 fever to produce brain damage. However, children will usually experience seizures, hallucinations and/or delirium even before it gets that high. Any of those symptoms requires emergency treatment, even if the temperature measured is less than 103.
At 105 and rising, it is time to call an ambulance; it is foolish to wait until brain damage actually occurs. Prevention is the best treatment, and children’s brains are very delicate.
True, 103 is usually not life-threatening, but it is the point where you begin aggressively treating the fever. Most ordinary childhood illnesses should not produce a temperature above 103 for very long; if it goes higher and Tylenol/Motrin/a cool bath isn’t reducing it to 102 or so, you should call a doctor immediately.
I usually don’t speak so sharply, but as you claim to be in the health field, I have to be clear so that people don’t listen to your dangerous advice.
