A fever is defined as a body temperature of 99°F or 37°C or higher. The body has natural ways to maintain a normal temperature, but it develops a fever in cases of an illness or infection. A febrile illness is when the body suddenly develops a fever. When your little one has a fever, it can be stressful. But understanding the causes behind the fever can help you take care of your child and have them feeling healthy in no time.

What are the causes of febrile illness in children?

Fevers are not an illness in itself but a symptom of an underlying issue or condition. Your child’s body temperature becomes raised when it is fighting against an infection or illness. The causes of fever in kids depend on whether it is acute (less than 7 days) or chronic (more than 10-14 days). Acute fevers in young children and infants are often caused by infections such as viral respiratory or gastrointestinal infections or bacterial infections. Chronic fevers that occur daily for 14 days or longer often have varied cause that required investigation.

Febrile illness in children is a sudden spike in temperature as the body is trying to fight off invaders like bacteria or viruses. In most cases, the fever develops suddenly and subsides within a day or two. It can be hard to determine the underlying cause in such a short time. But in some cases, it can be a symptom of something more dangerous like malaria, dengue, encephalitis and other serious conditions. Some children may also experience seizures when they develop a high temperature.

How is paediatric febrile illness treated?

If your child’s fever lasts more than two days, you should take them to the doctor. In the meantime, speak to a doctor to understand if it is safe to give them paediatric antipyretic medication but if your child has very high fever and appears drowsy and sick, consult your peadiatrician at the earliest. Give your child plenty of fluids such as juices and soup. Dress them in light clothing to allow their body temperature to reduce. If necessary, give them a lukewarm bath. If the fever persists, the doctor may recommend a blood or urine test to determine the underlying cause.
