preventing child fever

Overview

Fever is a rise in body temperature. It is usually a sign that your child's immune system is fighting an infection. This article shares practical steps to help reduce the chances of infections that can cause fever in children.

Yes, fever is very common in childhood. Most children will have several fevers before they start school.

It affects children of all ages, especially infants and young children who are still building their immune systems.

Symptoms

Common symptoms

• Temperature higher than normal (feel hot to the touch)
• Flushed or red cheeks
• Shivering or chills
• Sweating or feeling clammy

Symptoms in children

• Being more fussy or irritable than usual
• Sleeping more than normal or hard to wake
• Drinking less or refusing fluids
• Complaining of headache or body aches
• Vomiting or diarrhea

Causes

Main causes

• Viral infections like colds, flu, and stomach bugs
• Bacterial infections like ear infections, tonsillitis, or urinary tract infections
• Immunizations (some vaccines can cause a mild fever)
• Teething may cause a slight rise in temperature, but not a high fever

Risk factors

• Attending daycare or preschool
• Having older siblings who bring germs home
• Not being up to date on routine vaccinations
• Sharing toys, cups, or utensils with sick children
• Weakened immune system

When to see a doctor

See a doctor urgently if:

• A baby under 3 months with any fever
• Signs of dehydration (dry lips, no tears, fewer wet diapers)
• Fever lasting more than 3 days
• Your child looks very unwell, is limp, or is not responding normally
• Repeated vomiting or severe diarrhea

Book a routine appointment if:

• Fever with mild cold symptoms that lasts a day or two
• Fever after a vaccination (to get reassurance)
• Worries about your child's symptoms

Diagnosis

Your doctor will ask about your child's symptoms, check their temperature, and do a physical examination. They will look for the source of the fever, like an ear or throat infection.

Tests that may be done

• Usually no tests are needed for a simple viral fever
• A urine test may be done for babies or if a urinary infection is suspected
• Blood tests may be ordered if the fever is high or persistent
• A throat swab or other sample may be taken if a bacterial infection is likely

What to expect at your appointment

The doctor will explain what may be causing the temperature and give you advice on watching your child at home. They may recommend a follow-up visit if things change.

Treatment

The main goal is to make your child comfortable and help them drink enough fluids. Fever itself is not an illness but a sign your child's immune system is working. Not all fevers need medicine.

Self-care at home

• Give plenty of fluids—water, milk, or oral rehydration drinks—little and often
• Keep your child home to rest if they feel unwell
• Dress them in light clothing and keep the room at a comfortable temperature
• Do not wrap them in too many blankets or use cold baths, which can increase discomfort
• Offer bland foods like toast or crackers if they are hungry

Medical treatments

Your doctor or pharmacist may recommend a fever-reducing medicine to help with discomfort. Always follow the dose instructions for your child's age and weight. Never give adult medicine to children.

When is surgery considered?

Not applicable for treating a fever itself. Surgery is only needed for certain underlying infections, like an abscess, and this is rare.

Living with this condition

During a fever, keep your child comfortable and focus on rest and fluids. After the fever passes, they may still be tired for a few days. Let them recover at their own pace.

Lifestyle tips

• Wash your child's hands often with soap and water
• Teach older children to cover their mouth when coughing or sneezing
• Clean toys and surfaces regularly, especially when someone is sick
• Make sure your child gets enough sleep to support their immune system

Diet and exercise

Offer plenty of fluids while the fever lasts. When the fever breaks, your child can return to normal eating and gentle play. Don't push exercise until they feel better.

Mental health and emotional wellbeing

Caring for a sick child can be stressful. It is normal to feel worried. Talk to your doctor or a trusted health professional if anxiety is affecting your wellbeing or sleep.

Prevention

You can reduce the spread of infections that cause fever, but you cannot prevent every fever. Good hygiene, vaccination, and staying home when sick all help.

Vaccines

Make sure your child receives the routine childhood vaccinations recommended by your country's health authority. These protect against serious illnesses that cause high fevers.

Screening programmes

There is no routine screening test for preventing fever. Regular check-ups with your child's doctor help monitor healthy development and catch issues early.

Complications

If left untreated

• Dehydration, especially if your child refuses to drink
• Febrile seizures (which look scary but are usually brief and not harmful)
• A bacterial infection that spreads beyond the initial site, like a lung or kidney infection

Long-term outlook

The outlook is very good. Most childhood fevers are short-lived and get better within 3 to 5 days. With rest, fluids, and loving care, your child will usually recover fully.
