Mild Fever: To treat or not to treat?

Mild fever, by itself, is not harmful or dangerous. In fact, a fever is your body trying to fight off an infection. A fever occurs when your body’s internal thermostat rises above its normal temperature of 37°C. Common causes of a fever in children include infections, immunizations and overdressing (especially in infants and newborns).

In the past, treatment of a child’s fever was based on body temperature alone. Recently, recommendations on the treatment of a fever state that it should be based on a combination of body temperature and child’s overall condition. There is no evidence that a mild fever is harmful. Additionally, treating a fever with medications does not reduce the risk of seizures that are caused by the fever itself.

In children, fevers less than 38.9°C often do not require treatment. At this temperature, only treat if you believe it will make your child feel more comfortable. If the child is playing, drinking well, and alert, there is no need to treat with medication. Even if your little one is refusing to eat food, but is otherwise doing well don’t worry about treating, as it is common to not feel like eating when you have an infection that is causing a fever. Just simply monitor for any changes in symptoms or behaviour.

In infants and children under the age of 5 we recommend measuring temperature using a digital thermometer under their armpit, this is called taking their axillary temperature. This method is the least invasive and easiest to carry out in this age group. Normal axillary temperature is 34.7-37.3°C. Any temperature over 37.3°C is a fever. A temperature of 37.3-38.9°C is a mild or low grade fever and parents should use their judgement on whether or not to treat based on the child’s other symptoms.
