Is urticaria contagious?

Urticaria (hives) is generally not contagious. Most cases are associated with genetic factors or allergic reactions and are classified as an autoimmune disorder; therefore, they cannot be transmitted from person to person. Patients should typically seek care at the dermatology department of a reputable hospital and, under the guidance of a qualified physician, take antihistamine medications—such as cetirizine or loratadine—for treatment.
