Can hives be transmitted to others?

Urticaria is usually not contagious to others.

Urticaria usually presents as wheals and angioedema, and may be accompanied by itching, tingling, or burning sensation. Urticaria is not an infectious disease caused by a pathogen infection, so it is not contagious to others. The pathogenesis of urticaria is due to the body's allergy to certain substances, such as food, drugs, etc., which causes the immune system to overreact and release histamine, serotonin, etc. chemicals, which cause an inflammatory reaction on the skin. Some infectious factors can induce urticaria. Such pathogens can be infectious, but urticaria itself is not infectious.

If urticaria symptoms occur, it is recommended to seek medical examination and receive professional treatment.
