Signs and Symptoms of Fever

​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 they are uncomfortable or have 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.

What are the signs and symptoms of fever in children?

If your child has a fever, they may feel warm, appear flushed or sweat more than usual. They may also be more thirsty than usual.

Some children feel fine when they have a fever. However, most will have symptoms of the illness that is causing the fever. Your child may have an earache, a sore throat, a rash or a stomach ache. These signs can provide important clues as to the cause of the fever.
