Fever

An elevated body temperature is referred to as a fever. It represents your body's defense mechanism against illness. A fever in adults is defined as a temperature more than 100.4°F. When a child's temperature exceeds 100.4°F (measured rectally), 99.5°F (measured orally), or 99°F, it is said to be feverish (measured under the arm).

The normal body temperature is 37 degrees Celsius, or 98.6 degrees Fahrenheit. A few degrees above normal fever in you or your child indicates that they are healthy and actively battling infection. That's often a positive thing. However, if a fever persists after a few days and rises above 102°F, it should be treated at home and, if necessary, by a healthcare professional.
