Do you suffer from hives? This week marks World Allergy Week, and the theme for this year’s event is The Agony of Hives - What to do when welts and swelling do not go away.
The medical name for hives is urticaria. Hives are a common sign of an allergic reaction. Hives can also occur due to other causes, including a viral infection.
Learn more by visiting Hives (Urticaria). Find out when to call your health care provider, and when to go to the emergency room or call 911.
Hives can occur due to unknown causes. We call these types of hives idiopathic urticaria. Idiopathic means “unknown cause.” Hives can also be chronic. When you have chronic hives for an unknown reason, your doctor may diagnose you with Chronic Idiopathic Urticaria, or CIU.
World Allergy Week is an annual initiative of the World Allergy Organization (WAO). The WAO is made up of 97 allergy and immunology medical groups from around the world. The WAO says up to 1.8% of the world's population suffers from CIU.
