preventing school age

Overview

Keeping your school-age child healthy by stopping common infections from spreading and building habits that support a strong immune system.

Yes, colds, stomach bugs, and other infections are very common in school-age children. Most get better with rest and home care.

Children from about 5 to 12 years old who go to school or daycare, where germs spread easily between classmates.

Symptoms

Common symptoms

• Runny or stuffy nose
• Cough and sore throat
• Mild fever
• Tiredness or low energy
• Upset stomach or vomiting

Symptoms in children

• Fussiness or irritability
• Poor appetite or not wanting to drink
• Clinginess or wanting extra comfort
• Trouble sleeping

Causes

Main causes

• Viruses and bacteria spread in classrooms, on shared toys, desks, and in bathrooms.
• Coughing, sneezing, touching your face, and not washing hands.
• Sharing food, utensils, water bottles, or personal items like hats and combs.
• Not being up to date on routine vaccinations.

Risk factors

• Being in a school or daycare with many other children
• Having a medical condition that weakens the immune system
• Not getting enough sleep or eating a limited diet
• Being around people who smoke, as this can increase breathing infections

When to see a doctor

See a doctor urgently if:

• If your child has any of the emergency signs listed above
• If your child has a very high fever that does not improve with simple fever relief
• If your child is in severe pain or cannot keep down fluids

Book a routine appointment if:

• If symptoms last longer than a week
• If you have questions about vaccines or the recommended schedule
• If you need help managing a long-term condition like asthma or allergies

Diagnosis

A doctor or nurse will ask about your child's symptoms, examine them, and may ask about what is going on at school. Many infections are diagnosed based on symptoms alone.

Tests that may be done

• A swab from the throat or nose to check for viruses or bacteria
• A urine sample if a urinary tract infection is suspected
• A blood test if the doctor needs more information or wants to rule out another condition

What to expect at your appointment

The visit is usually quick. Share what symptoms you have noticed, when they started, and whether anyone else at home or school is sick. The doctor will tell you how to help your child feel better and when to come back.

Treatment

Treatment focuses on comfort, rest, fluids, and bringing down fever. Antibiotics are only useful for bacterial infections, not for viral infections, so they are not prescribed for most colds and coughs.

Self-care at home

• Encourage extra rest and fluids like water, clear soups, or oral rehydration drinks.
• Use a cool-mist humidifier in the room or saline drops in the nose to help with a blocked nose.
• Give simple pain and fever relief as recommended by your pharmacist or doctor, and always check the right product and dose for your child's age.

Medical treatments

A doctor may prescribe antibiotics if a bacterial infection such as strep throat or an ear infection is confirmed. Antiviral medicines are sometimes used for specific viruses like the flu. Always give any medicine exactly as directed by a healthcare professional.

When is surgery considered?

Surgery is rarely needed for common childhood infections. You would be referred to a specialist only if an infection causes a collection of pus (abscess) or another rare complication.

Living with this condition

Create a simple family routine that supports sleep, handwashing, and healthy meals. Teach your child to cough or sneeze into their elbow, to use a tissue, and to wash their hands after using the toilet, before eating, and after playing outside.

Lifestyle tips

• Set a regular bedtime so your child gets enough sleep for their age.
• Encourage at least one hour of physical activity each day.
• Spend calm time together and talk about school and friends to help manage stress.

Diet and exercise

Offer a balanced diet with fruits, vegetables, whole grains, and protein. Limit sugary drinks and snacks. Regular movement and active play help keep the immune system strong.

Mental health and emotional wellbeing

Repeated illnesses can be stressful for both your child and your family. Give extra reassurance and watch for signs of worry or low mood, such as not wanting to go to school or losing interest in usual activities. Talk to your child's doctor if you are concerned.

Prevention

Many common infections can be prevented with good hygiene, up-to-date vaccinations, and healthy habits. You cannot prevent every cold, but you can lower the chance of your child getting sick and spreading germs to others.

Vaccines

Make sure your child's routine vaccinations are up to date. Your local health service or family doctor can tell you which vaccines are recommended and when to have them.

Screening programmes

Regularly check for head lice, especially if there has been an outbreak at school, and treat them if found. Routine dental check-ups are also an important part of staying healthy.

Complications

If left untreated

• Some infections like flu or strep throat can lead to ear infections, sinusitis, or dehydration.
• Rare complications of bacterial infections can include serious conditions like rheumatic fever.
• Children who are not vaccinated can catch diseases like measles or whooping cough, which can be severe or even life-threatening.

Long-term outlook

With rest, fluids, and simple care, most children recover completely within a week or two. Building healthy habits from a young age helps your child stay strong, miss fewer school days, and feel better overall.
