“My Child Often Gets Sick After Starting School” – Should Parents Be Worried?
At the seminar “Why Does My Child Often Get Sick? Decoding the Immune Army,” Dr. Lan Huong from Vinmec helped parents gain a proper understanding of why young children often fall ill during their preschool years. The event, held as part of the collaboration between Vinschool and the Vinmec Healthcare System, provided parents with scientifically grounded and practical knowledge to accompany their children in building a strong foundation for lifelong health.
The Child’s Immune System – A “Trainee Army”
At the seminar, Dr. Lan Huong shared: “The immune system is like an army that protects the ‘kingdom of the body’ from viruses and bacteria.”
Why Do Children Often Get Sick When They Start School?
At kindergarten, children play and interact together in shared spaces, creating conditions where bacteria and viruses can easily spread. Dr. Lan Huong explained: “When exposed to various new pathogens, a child’s immune system is being ‘trained’ and gradually becomes more mature. Therefore, frequent minor illnesses at this age are not a sign of weakness, but rather a natural and essential part of the immune system’s development.”
When Should Parents Be Concerned?
Most mild illnesses can be monitored and cared for at home. However, parents should seek medical attention immediately if their child shows any of the following warning signs:
- High fever lasting several days without improvement.
- Difficulty breathing, rapid breathing, or chest retraction.
- Lethargy, seizures, or complete refusal to eat or drink.
- Signs of dehydration (no urination, excessive thirst, dry lips).
Advice for Parents From Expert
- To protect children’s health while still allowing their immune system to “train” effectively, parents can:
- Build a comprehensive health foundation: Maintain five essential elements – balanced nutrition, daily physical activity, sufficient sleep, good personal hygiene, and full vaccination.
- Observe closely and act promptly: Recognize early warning signs and seek timely medical care to prevent complications.
Frequent minor illnesses when children first start school are normal and necessary for the immune system’s development. What parents need is not excessive worry or delaying school attendance, but patience, evidence-based care, and knowing when medical intervention is needed.
