What are the causes of a fever in children?

Answered on 11th January 2016

If your little one has a fever, it’s likely their body is fighting an infection. In some cases, the cause will be obvious to you, like the flu or chickenpox. But a fever can also be due to illnesses like colds, sore throats and ear infections. Remember that a fever is the body’s way of fighting off infections, and are usually not cause for concern.

Some uncommon, but more serious causes of a fever include urinary tract infections, pneumonia, meningitis and sepsis. If you’re concerned, it’s always fine to call your GP.

If your child isn’t poorly, keep in mind that vaccinations, teething and even just being overheated can also cause a fever.
