As the schools are set to reopen across the UAE and children return to classrooms after the long summer break, there is also a return of sniffles, sneezes, and sick days. It’s a familiar pattern many parents recognise. Children head back to school in high spirits, only to fall ill within the first few weeks of term.
The change in routine, new environments, close contact with classmates, and exposure to new germs all play a role in this seasonal spike in infections. In this feature, Connector breaks down why immunity dips during this season, what common illnesses to watch out for, and most importantly, how parents can actively help boost their child’s natural defences. With expert advice, we’ll take you through simple, practical steps to help your child stay healthy.
Why Do Children Fall Sick More Often During Back-To-School Season?
Returning to school means children are suddenly surrounded by large groups of peers after weeks of summer break, often spent indoors. Classrooms, cafeterias, buses, and shared play areas become hotspots for the transmission of infections, especially those that spread through droplets or touch.
"When children stay in confined spaces without much exposure during the holidays and then return to busy classrooms, even one sick child can lead to many more falling ill”, says Dr. Lakshmi Prasad, Paediatrician at NMC Medical Centre, Al Majaz.
Dr. Radhika K Naidu, Specialist Paediatrician at JTS Medical Centre in Jumeirah, adds, “Back-to-school season is always hectic. And we see a predictable surge in infections every year, from respiratory illnesses to seasonal allergies and even stomach bugs”.
Children typically don’t usually pay much attention to respiratory or hand hygiene unless they are specifically taught. That increases the chances of spreading respiratory and airborne infections.
Understanding what these illnesses are and what symptoms to look out for is the first step in tackling them effectively.
Common Illnesses During The Season
Experts note that it is important to consult with the primary physician to confirm any illness or infection that children may have. Dr. Radhika K Naidu from JTS Medical Centre lists a few of the most common illnesses seen among children during the back-to-school season:
1. Seasonal flu and upper respiratory infections
These are among the most common issues in school-going children. Watch for signs like a runny nose, nasal congestion, fever, chills, sore throat, dry cough, and body aches.
2. Gastrointestinal infections (stomach bug)
These are infections affecting the stomach and intestines. Symptoms include vomiting, diarrhoea, abdominal cramps, and fever. These can lead to dehydration if not addressed promptly.
3. Ear infections
Usually occurring as a complication of colds or allergies, ear infections can present with fever, fussiness, ear pain, and nasal congestion.
4. Seasonal allergies
Children sensitive to dust, pollen, or weather changes may experience wheezing, sneezing, rashes, or a persistent dry cough.
While these illnesses are common, the good news is that many of them can be prevented or managed with the right immunity support.
How To Build Your Child’s Immunity
Nutrition is key, a strong immune system begins with good nutrition. “Watch your child’s food habits. Avoid junk food and calorie-rich snacks with little nutritional value”, advises Dr. Lakshmi Prasad from NMC Medical Centre.
A balanced diet should include:
-
Fruit and vegetables, especially those rich in antioxidants, such as berries, citrus fruits, spinach, and carrots.
-
Protein-rich foods, such as lean meats, eggs, lentils, and dairy products.
-
Healthy fats, like nuts, seeds, and fish for essential fatty acids.
-
Whole grains, for sustained energy and digestive health.
Dr. Radhika K Naidu from JTS Medical Centre adds, “Zinc, Vitamins C and D, Omega-3, and B-complex are particularly important to strengthen your children's natural defence to illnesses. These can be found in food or prescribed supplements if needed”.
Experts agree that water plays a vital role in flushing out toxins and maintaining overall health. Make sure your child drinks enough water throughout the day, especially when the weather is hot and humid.
Adequate sleep and rest allows the body to reset and repair, building resistance against infections. "Ensuring children get enough sleep helps reset and rebuild the immune system, making them more resilient to illnesses", says Dr. Radhika K Naidu from JTS Medical Centre. Depending on age, school children generally need between 9 to 11 hours of quality sleep each night.
Encouraging physical activity and outdoor play, not only improves physical health but also stimulates the immune system. “Light exposure to sunlight helps the body produce Vitamin D naturally, which is essential for strong immunity”, adds Dr. Radhika K Naidu from JTS Medical Centre.
Allow time for outdoor play when possible, before or after school, while also ensuring children are protected against excessive heat.
Teaching Hygiene: A Skill For Life
Hand hygiene and respiratory etiquette are among the most effective, yet often overlooked, methods to prevent illness.
Dr. Lakshmi Prasad from NMC Medical Centre and Dr. Radhika K Naidu from JTS Medical Centre recommends that parents teach children to:
-
Wash hands properly with soap and water after using the toilet, before meals, and after returning home from school.
-
Use hand sanitisers if soap and water are not available.
-
Cover their mouth and nose with their elbow, and not hands, when coughing or sneezing.
-
Avoid sharing water bottles, food containers, or personal items in school.
These habits, once instilled, can go a long way in reducing the spread of infections.
Don’t Skip Vaccinations
Vaccinations remain one of the most reliable ways to prevent severe illness. "Flu vaccines are particularly recommended during September and October in the UAE, as the flu is most common during this period", shares Dr. Lakshmi Prasad from NMC Medical Centre.
Ensure your child is up to date with their age-appropriate vaccines. If you’re unsure, consult your paediatrician to discuss which seasonal or routine shots are needed.
Know When To Keep Your Child Home
One of the biggest contributors to infection spread is sending unwell children to school. “If your child is showing signs of infection, including fever, sore throat, vomiting, or diarrhoea, keep them at home and seek medical attention”, says Dr. Radhika K Naidu from JTS Medical Centre.
This not only helps your child recover faster but also protects other children in the classroom.
Early Detection And Timely Care
Always monitor symptoms early. Recognising the signs of illness helps you take prompt action and prevents complications. Both experts agree that self-diagnosis is not appropriate. Consult a physician to confirm the nature of the illness and get proper treatment.
Also, during recovery, make sure your child is well-hydrated, rested, and nourished to bounce back stronger.

Back to school doesn’t have to mean back to the doctor’s office. With thoughtful preparation and consistent care, you can give your child the strongest start to the academic year ahead.
