Introduction
In general, urticaria is not contagious. Urticaria is a common allergic skin condition characterized primarily by rashes, itching, and pain. It may be associated with factors such as allergen exposure, improper diet, or inappropriate use of medications. When allergens enter the body, they trigger mast cells to release inflammatory mediators such as histamine, which may lead to dilation of skin capillaries and increased vascular permeability.
Generally, urticaria is not contagious. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified physician. The specific analysis is as follows:
Urticaria is a common allergic skin condition characterized by rashes, itching, and sometimes pain. It may be triggered by allergens, improper diet, inappropriate use of medications, and other factors. When allergens enter the body, they prompt mast cells to release inflammatory mediators such as histamine, leading to dilation of skin capillaries and increased vascular permeability, which results in the symptoms of urticaria. Pathogens such as bacteria and viruses are not involved in this process, so urticaria cannot be transmitted to others. Therefore, urticaria is non-contagious.
Patients with urticaria should, under medical supervision, use medications such as cetirizine tablets, loratadine tablets, or dexamethasone tablets for treatment. Daily skin care is also important—keep the affected area clean and dry, and avoid excessive scratching to promote skin recovery.
