Fever is a symptom and not a disease; it has many possible causes. You can have fever due to viral or bacterial infection or simply too much sun. Fever is a common symptom in children and temperatures between 100°to 104°F in children and adults are not harmful. In most cases fever needs symptomatic treatment (such as fever reducing medications, drinking plenty of fluids, and rest).
