recovery after child fever

Overview

A fever is a temporary rise in body temperature, usually caused by an infection. Recovery is the time it takes for your child's body to fight off the infection and return to normal temperature and energy levels.

Yes. Fever is one of the most common reasons parents contact a doctor. Most children will have several fevers in their early years.

Children of all ages, but it is most common in babies and toddlers under 5 years old, especially as their immune systems are still developing.

Symptoms

Common symptoms

• High temperature that comes and goes
• Sweating or chills
• Flushed cheeks
• Feeling tired or listless
• Loss of appetite

Symptoms in children

• Fussiness or being more irritable than usual
• Wanting to be held or comforted
• Not drinking as much as normal
• Warm, damp skin
• Fast breathing or fast heartbeat

Symptoms in older adults

• Fever in older adults can be less obvious and may simply present as confusion, weakness, or a sudden loss of energy.
• Lower body temperatures may already be a sign of a serious infection. If you are caring for an older adult with a fever, seek medical advice promptly.

Causes

Main causes

• Viral infections such as colds, flu, and childhood illnesses like chickenpox
• Bacterial infections like ear infections, throat infections, or urinary tract infections
• Immunisations (vaccinations) can cause a mild fever for a day or two

Risk factors

• Age under 5 years
• Attending daycare or school (increases exposure to germs)
• Not being fully vaccinated against preventable infections
• Underlying health conditions that weaken the immune system

When to see a doctor

See a doctor urgently if:

• If your child is under 3 months old with any fever
• If the fever is persisting beyond a few days or is very high
• If your child has a fit (seizure), difficulty breathing, or a rash that doesn't fade
• If your child is severely dehydrated — no wet nappies for 6 hours, dry mouth, sunken eyes

Book a routine appointment if:

• If you are worried about your child's symptoms, even if they seem mild
• If the fever returns after being gone for a day or more
• If your child has an underlying health condition, such as a heart or lung problem
• If you need advice on how to make your child more comfortable

Diagnosis

The doctor will ask about your child's symptoms, examine them, and may check their temperature, breathing, heart rate, and hydration. They will look for the source of the infection.

Tests that may be done

• A urine test to check for a urinary tract infection
• A blood test to look for signs of infection
• A throat swab or chest X-ray if a chest infection is suspected

What to expect at your appointment

Often no tests are needed. The doctor will explain what is likely causing the fever and give you advice on home care and warning signs to watch for. If a bacterial infection is found, they may recommend treatment — always follow their instructions.

Treatment

The main treatment for a fever caused by a virus is rest, fluids, and time. Medicines are sometimes used to make a child more comfortable, but they do not treat the cause. Always ask a doctor or pharmacist before giving any medicine to a child.

Self-care at home

• Encourage your child to drink plenty of fluids — water, diluted juice, or oral rehydration solution if available
• Make sure your child rests and sleeps as much as possible
• Dress your child in light clothing and keep the room at a comfortable temperature — not too hot
• Wipe your child's face and neck with a cool (not cold) cloth to help them feel better
• Offer small, light meals if they feel like eating, but do not force food

Medical treatments

If a bacterial infection is causing the fever, such as an ear infection, a doctor may prescribe a course of antibiotics. These must be taken exactly as directed. For viral infections, antibiotics do not work. In hospital, treatment focuses on fluids and close monitoring. Medicines to lower a fever are available over the counter — your pharmacist or doctor can tell you the right type and dose for your child's age and weight.

When is surgery considered?

Surgery is not relevant for a simple fever. It may be considered only if the fever is caused by a surgical condition, which is very rare in children.

Living with this condition

During recovery, keep your child comfortable and watch their temperature and fluid intake. A normal temperature for children is around 36 to 37°C (96.8 to 98.6°F). It is normal for a fever to spike and fall over a few days. Check on your child regularly, especially at night.

Lifestyle tips

• Keep the house calm and quiet
• Allow your child to decide when to rest and when to play
• Keep other children away from your child if they have an infectious illness
• Wash your hands frequently to stop the illness spreading

Diet and exercise

Do not force your child to eat, but encourage them to drink regularly. Easy-to-digest foods like soup, toast, bananas, and yoghurt are good options. Once the fever settles, your child can gradually return to normal activity and a balanced diet. Exercise should wait until they feel fully better.

Mental health and emotional wellbeing

It can be worrying when your child is ill, and you may feel anxious or stressed. Remember that most fevers are short and harmless. Look after your own wellbeing too — ask for help from family or friends if you need a break.

Prevention

Not all infections can be prevented, but good hygiene can reduce the spread of many germs. This includes washing hands regularly, covering coughs and sneezes, and keeping surfaces clean.

Vaccines

Vaccination is one of the most effective ways to protect your child from serious infections that cause fever. Follow your country's immunisation schedule and speak to your doctor if you have questions.

Screening programmes

There is no routine screening for fever itself. Screening relates to the underlying illness, such as checking urine in babies or blood tests if an infection is suspected.

Complications

If left untreated

• Dehydration, if your child does not drink enough fluids
• Febrile seizures (fits) in some children between 6 months and 5 years old, which can be frightening but are usually short and do not cause lasting harm
• A bacterial infection, such as a chest infection or bloodstream infection, that may spread and become more serious if not treated

Long-term outlook

The vast majority of childhood fevers are caused by mild viral infections and resolve on their own within a few days. Even if your child has a febrile seizure, the outlook is excellent. With proper care and medical advice, your child will return to their usual self quickly. Rest, love, and attention go a long way.
