What is Urticaria
Urticaria (also known as hives) is a disease characterized by the sudden development of itchy pale red bumps (wheals, hives) on the skin. Wheals may present in variable sizes and shapes and have a fleeting nature, with the skin returning to its normal appearance in around 24 hours. These wheals may appear in certain parts of the body, or they may be generalized. Hives are often accompanied by swelling known as angioedema.

How Well Do People Understand Urticaria?
One of the goals of UDAY 2026 is to improve understanding of urticaria and its impact on daily life.
Take our quick public awareness survey and help us explore how people perceive urticaria and other chronic inflammatory conditions. The results will help identify gaps in awareness and support future education and advocacy efforts.
The survey takes just 1–2 minutes to complete.
