Urticaria in an 8-year-old child is usually related to allergic reactions, infections, or physical irritants. It is recommended to promptly identify the triggering factor and seek medical attention. Specific causes may include the following:
1. Food or drug allergies: Children may have allergic reactions to certain foods (such as eggs, milk, seafood) or medications, which can cause hives and itching on the skin.
2. Infectious factors: Viral infections such as colds and tonsillitis, or bacterial infections, can sometimes trigger urticaria.
3. Environmental irritants: Exposure to pollen, dust mites, animal dander, or physical irritants such as heat, cold, or sunlight may also lead to symptoms.
4. Immune system response: Children's immune systems are not yet fully mature and are prone to overreacting when exposed to certain substances.
In daily care, parents can record their child's diet and activities to help identify allergens; prevent children from scratching their skin and dress them in loose cotton clothing. If symptoms recur or are accompanied by discomfort such as shortness of breath, seek medical attention promptly for examination and use anti-allergy medications or targeted treatment under the guidance of a doctor.
