Is artificial urticaria contagious?

Artificial urticaria is a disease caused by allergies, and it is one of the more difficult types of urticaria to treat. This disease is not contagious and will not spread through contact with others. Once diagnosed with this disease, formal treatment is necessary, and one can visit the dermatology department of a standard hospital for oral antiallergic medication treatment. If the condition persists for a long time and the treatment effects are unsatisfactory, it might be helpful to check for allergens to ascertain what triggers the allergy. Common allergens often include diet, living environment, dust mites, or pollen. Therefore, during and after treatment, it is advisable to enhance physical exercise to boost immunity, avoid keeping pets, stay away from places with dense vegetation, and refrain from consuming spicy and stimulating foods.

Can urticaria be contagious?

Urticaria is not contagious. Urticaria, also known as wheals or commonly referred to as hives, is caused by temporary increased vascular permeability in the skin and mucous membranes due to allergic factors, resulting in localized edema. Wheals generally subside quite quickly, typically within 24 hours. The causes of wheals, which are essentially urticaria, may include the food we eat, airborne inhalants, and skin contact with substances such as pollen, dust mites, mold mites, as well as animal dander, fur, etc. Additionally, some cases may be related to infections, and some people may have a lethal factor due to suspicious medications. Moreover, the occurrence of urticaria can also be related to other factors such as cold, heat, ultraviolet light, and mechanical stresses such as friction or pressure. Furthermore, other factors including psychological and endocrine factors can also lead to the occurrence of urticaria.
