Urticaria after cold in children

Urticaria after a cold in children may be related to abnormal immune response, and timely itching and swelling relief and targeted treatment are required. Cold viruses or bacterial infections may affect the immune system, causing allergic reactions in the body, leading to skin rashes, itching and other symptoms. At the same time, factors such as drugs, food, and environmental stimuli may also induce or aggravate urticaria. Parents need to closely observe changes in their children's symptoms to determine whether they need to seek medical attention.

The formation of urticaria after a cold in children may involve a variety of reasons. Genetic factors are an important background. If there is an allergic constitution or history of urticaria in the family, the risk of such reactions in children will increase. Environmental factors include weather changes, contact with allergens (such as pollen, dust mites) or food allergies (such as nuts, eggs, etc.), which can induce or aggravate abnormal immune responses. Physiologically, colds cause overactivation of the immune system, which may cause mast cells to release substances such as histamine, which directly leads to the occurrence of urticaria. When children use antipyretics, cold medicines and other drugs, they may also develop drug allergies due to individual differences, further causing skin symptoms. Symptoms generally manifest as red or white papules, accompanied by itching or even slight swelling.

Treatment should be selected according to the severity of the disease. Antihistamines such as loratadine, cetirizine or desloratadine can be used for mild cases. These drugs can relieve itching and eliminate wheals. When the symptoms are significant, you can follow the doctor's advice to apply low-efficiency steroid creams such as hydrocortisone cream to reduce local inflammatory reactions. If there are obvious signs of infection or drug allergies, the suspected drugs should be discontinued in time, and anti-infection or desensitization treatment should be cooperated. In daily care, pay attention to prevent children from scratching itchy areas to prevent infection. Soft, breathable cotton materials are recommended for clothing to avoid skin irritation.

In daily care, parents need to provide children with light, easily digestible food, avoid ingredients that may cause allergies, and gradually identify potential allergens. If the rash occurs frequently or is accompanied by other symptoms (such as swelling of the face and lips, difficulty breathing, etc.), the child should be taken to the doctor in time to rule out the possibility of other diseases or complications.
