Affinity Health, a leading provider of high-quality health cover, shares tips on recognising the early signs of common childhood illnesses in crèches and schools.

If you’re a parent, you know the routine all too well: one child in class gets sick, and suddenly, it feels like every child is home with a runny nose, cough, or a stomach bug. For families with kids in crèches and primary schools, frequent childhood illnesses often come with the territory, but that doesn’t mean they should be overlooked.

“Crèches and preschools are common hotspots for infections, thanks to close contact, shared surfaces, and developing immune systems,” says Murray Hewlett, CEO of Affinity Health.

“Recognising early symptoms and acting quickly can reduce the severity of illness and help stop the spread before it affects an entire classroom.”

The Most Common Crèche and School Illnesses

1. Colds and Flu

Almost unavoidable in large groups, cold and flu viruses spread through sneezing, coughing, and touch. Children may experience a blocked nose, sore throat, fatigue, and mild fever. While most recover on their own, flu symptoms like high fever, body aches, and chills can be more severe.

2. Gastroenteritis (Stomach Bug)

Often referred to as “stomach flu,” this highly contagious illness spreads through contact with contaminated food, water, or hands. Symptoms include vomiting, diarrhoea, stomach cramps, and low-grade fever. Dehydration is the biggest concern, especially in toddlers.

3. Conjunctivitis (Pink Eye)

Conjunctivitis is highly infectious and common in group settings. It causes redness, itching, and yellow or green discharge in the eyes. Children often rub their eyes and spread it unknowingly.

4. Ear Infections

Ear infections frequently follow a cold and are common in younger children. Signs include ear tugging, irritability, trouble sleeping, and fever. These infections may require antibiotics if they don’t clear up within a few days.

5. Hand, Foot and Mouth Disease

This viral illness causes small sores in the mouth and rashes on the hands and feet. It spreads through saliva, mucus, and dirty hands. Children under the age of five are most at risk.

6. Head Lice

Although not dangerous, lice are itchy, irritating, and very contagious. They spread quickly through close contact or shared items like hats and brushes. Look for excessive scratching or tiny white eggs (nits) behind the ears or at the nape of the neck.

7. Chickenpox (Varicella)

Chickenpox causes an itchy, blister-like rash, along with fever and fatigue. It’s most contagious before the rash appears and spreads rapidly in schools. While usually mild, it can cause complications in young infants or children with weakened immune systems.

How To Spot Illness Early

Children don’t always know how to explain how they feel, so it’s important to keep an eye out for subtle changes such as:

• Sudden tiredness or grumpiness.
• Loss of appetite or refusal to eat.
• Warm forehead or flushed cheeks.
• Coughing or unusual sounds when breathing.
• Rubbing ears, eyes, or tummy.
• Clinginess or lack of interest in playing.

Teach Good Hygiene Habits

Building healthy habits is one of the best defences against schoolyard germs.

Encourage children to:

• Wash hands after using the toilet and before eating.
• Cover their mouths with their elbows when coughing or sneezing.
• Avoid touching their face with dirty hands.
• Never share water bottles, cutlery, or facecloths.
• Tell a teacher if they feel sick.

Also, ensure they’re getting enough sleep, drinking sufficient water, eating nutritious meals, and are up to date with routine vaccinations.

Parent’s School Illness Checklist

• Keep your child home if they have a fever, vomiting, or diarrhoea.
• Notify the school of any contagious illnesses so they can take appropriate action.
• Check your child daily for symptoms or signs of discomfort.
• Pack tissues and hand sanitiser in their school bag.
• Teach your child about germs and how to prevent them from spreading.
• Speak to your GP if symptoms worsen or last longer than 2–3 days.

Conclusion

From sniffles to stomach bugs, school-related illnesses are a regular part of childhood, but knowing what to look for and when to take action can make all the difference. With the proper support, preventative steps, and accessible healthcare, you can help your child stay healthier, happier, and better prepared for the classroom this winter and beyond.
