healthwealth, I agree with Fairy Godmother. Fever itself is not a disease; it's rather a symptom of a disease. As said by Fairy Godmother, fever indicates something is going wrong. When an infection occurs, our immune system responds by increasing the body temperature so that it can kill the bacteria or virus that has caused the infection. I am not very sure, though, about the relationship between fever and diarrhea. By the way, 102.7 is not a mild fever for a child. As far as the recurrent nature of the fever is concerned, I think your son is developing a recurrent infection and the body is responding by recurrent fever. You cannot stop the fever permanently unless you find a cure for the infection that is causing the fever. As soon as the infection is gone, fever will also disappear. Your son is prone to infection probably because of a nutritional deficiency. Is he underweight? Anyways, you need to take him to the doctor sooner than later. I prey to God for your son's recovery.
