A fever is usually a sign that the body is fighting an illness or infection. Fevers are generally harmless. In fact, they can be considered a good sign that your child’s immune system is working and the body is trying to heal itself. While it is important to look for the cause of a fever, the main purpose for treating it is to help your child feel better if he is uncomfortable or has pain.
What is a Fever
Normal body temperature varies with age, general health, activity level, and time of day. Infants tend to have higher temperatures than older children. Everyone’s temperature is highest between late afternoon and early evening, and lowest between midnight and early morning. Even how much clothing a person wears can affect body temperature.
A fever is a body temperature that is higher than normal. While the average normal body temperature is 98.6°F (37°C), a normal temperature range is between 97.5°F (36.4°C) and 99.5°F (37.5°C). Most pediatricians consider a temperature above 100.4°F (38°C) as a sign of a fever.
