child fever risk reduction

Overview

A fever is a temporary rise in body temperature, usually caused by an infection. In children, it is one of the most common reasons parents seek medical advice. Risk reduction means knowing how to spot a fever, measure it accurately, keep your child comfortable and hydrated, and recognise warning signs that need medical help.

Yes. Fevers are very common in childhood, especially in the first few years of life, as children are exposed to many new infections.

Fever can affect any child, but it is most frequent in infants and young children, and especially in those who attend nursery or have older siblings in school.

Symptoms

Common symptoms

• Warm forehead, back, or tummy
• Flushed cheeks
• Shivering or feeling cold
• Sweating
• Tiredness and body aches
• Loss of appetite
• Mild headache

Symptoms in children

• Temperature above 38°C (100.4°F) measured under the arm or in the ear
• Clingy, fussy, or irritable behaviour
• Less playful than usual or low energy
• Drinking or feeding less than normal
• Sleeping more than usual
• Hot, flushed skin and sweating

Symptoms in older adults

• Fever in older adults (65+) can be a sign of a more serious infection and should be checked promptly
• Older adults may not always run a high fever, so watch for confusion, weakness, or a drop in energy
• Fever-reducing medicines can interact with other health conditions, so professional advice is important

Causes

Main causes

• Viral infections such as colds, flu, roseola, and chickenpox
• Bacterial infections such as ear infections, throat infections, urine infections, or pneumonia
• A mild fever after routine vaccinations
• Teething may cause a slight temperature rise, but usually below 38°C
• Overdressing a baby or being in a very hot environment can also raise body temperature

Risk factors

• Being under 5 years old, especially under 3 months
• Attending childcare or nursery
• Having older siblings who bring common infections home
• Not being up to date on routine vaccinations
• Having a weakened immune system due to another health condition

When to see a doctor

See a doctor urgently if:

• Any fever in a baby under 3 months old
• Fever with a rash that does not fade when pressed
• A seizure or convulsion
• Your child is very sleepy, difficult to wake, or floppy
• Difficulty breathing or fast breathing
• No urine output for 8 hours or fewer wet nappies than usual
• Fever above 40°C or lasting more than 5 days

Book a routine appointment if:

• Fever lasting more than 3 days
• Your child is not drinking enough and may be getting dehydrated
• Ear pain, sore throat, or pain when passing urine
• Repeated vomiting or diarrhoea
• Fever that keeps coming back after it had gone away

Diagnosis

A doctor will ask about your child's symptoms, behaviour, fluid intake, and any contact with someone who is ill. They will measure the temperature and do a physical examination to look for the cause — checking the ears, throat, chest, skin, and breathing. The doctor will also look for signs of dehydration.

Tests that may be done

• Temperature measurement using an under-arm, ear, or forehead thermometer
• Physical examination of the ears, throat, chest, and skin
• Urine test if a urinary tract infection is suspected
• Blood tests if a serious bacterial infection needs to be ruled out
• Chest X-ray only if pneumonia is suspected

What to expect at your appointment

In most cases, the doctor will explain the likely cause and give you advice on how to care for your child at home. Tests are not always needed. If tests are required, they are usually quick and simple. The doctor will tell you which warning signs to look out for and when to return.

Treatment

Treatment for a child's fever focuses on comfort and hydration, not on bringing the temperature down to normal. Fever is part of the body's defence against infection. If your child is uncomfortable, a suitable fever-reducing medicine may help, but it is not always necessary.

Self-care at home

• Offer plenty of fluids regularly — water, milk, or oral rehydration fluids in small, frequent sips
• Dress your child in light clothing and keep the room at a comfortable temperature
• Encourage rest, but let your child be as active as they feel comfortable being
• Offer soft, easy-to-eat foods if they want them, but do not force eating
• Watch your child's behaviour and fluid intake closely
• Do not bathe or sponge your child to cool them down — this can cause shivering and does not help

Medical treatments

If your child is in discomfort with a fever, a doctor or pharmacist may recommend a fever-reducing medicine appropriate for the child's age and weight. Always follow the dosage instructions and seek professional advice if unsure. Do not give more than one medicine at a time unless directed by a doctor. Never give aspirin to a child or young person, as it can cause a rare but serious illness.

When is surgery considered?

Surgery is never needed for fever itself. If an underlying condition such as appendicitis or a severe abscess is found, surgery may be part of treating that condition, but the fever alone never requires an operation.

Living with this condition

Most fevers settle within 2 to 3 days. During this time, keep a close watch on how your child is behaving, offer fluids often, and let them rest. You do not need to wake your child just to check their temperature if they are sleeping peacefully.

Lifestyle tips

• Maintain a normal sleep routine as much as possible
• Wash hands regularly, especially before eating and after using the toilet
• Keep your child's routine vaccinations up to date
• Teach older children to cough or sneeze into a tissue or their elbow
• Keep up with regular well-child visits

Diet and exercise

There is no need to change your child's usual diet during a fever, but fluids are more important than food. Offer small amounts of fluid often rather than large amounts at once. Once the fever goes, return to a normal balanced diet. Gentle activity can resume as soon as your child feels better.

Mental health and emotional wellbeing

A fever in your child can be stressful and worrying. It is normal to feel anxious, but try to remember that fever is often the body working as it should. If you feel overwhelmed, talk to your pharmacist, health visitor, or doctor. Your child can sense your calm, so keeping a steady routine helps everyone.

Prevention

You cannot prevent every fever, because most come from common viruses that spread easily between children. You can reduce the risk by encouraging good hand hygiene, keeping your child away from people who are sick when possible, and making sure they are fully vaccinated.

Vaccines

Vaccines are one of the best ways to prevent serious infections that cause fever, such as measles, mumps, rubella, whooping cough, and some forms of bacterial meningitis. Follow the vaccination schedule recommended in your country. A mild fever after a vaccine is common and usually short-lived.

Complications

If left untreated

• Dehydration if the child does not drink enough fluids
• Febrile seizure — a convulsion caused by a rapid rise in temperature; it can look alarming but is usually harmless and stops on its own
• In rare cases, an untreated serious bacterial infection can lead to more severe illness

Long-term outlook

The outlook for children with fever is very good. Most recover fully within a few days without any long-term problems. Even when a febrile seizure occurs, most children develop normally afterwards. The most important steps are careful monitoring, supportive care, and seeking medical advice when you are concerned. With the right support, your child will soon be back to their usual playful self.
