Why can the child give urticaria

The cause of urticaria in children is relatively complex. Generally, it is related to food, infection, respiratory tract inhalants and skin contacts.

1. Food

If children eat animal protein, plants or fruits, rotten food, etc., it may cause allergic reactions in the body, resulting in vasodilation and increased vascular permeability, causing urticaria.

2. Infection

When children are infected with upper respiratory tract viruses, Staphylococcus aureus, fungi and parasites, inflammatory cells will be activated, causing urticaria.

3. Respiratory tract inhalants and skin contacts

If children inhale pollen, animal dander, volatile chemicals, etc. or skin contact with certain plants and animal hair, it will lead to smooth muscle contraction and increased glandular secretion, thus causing urticaria.
