Washington, DC, Oct. 01, 2025 (GLOBE NEWSWIRE) -- On this Urticaria Day (UDAY), the Asthma and Allergy Foundation of America (AAFA), We CU, and The Mast Cell Disease Society (TMS) aim to raise awareness of urticaria (hives) and provide information on managing a skin condition that can dramatically impact the lives of those affected.
Acute hives last a short time – between a few hours to a few days, or less than 6 weeks. They may go away on their own. They can occur as part of a viral or bacterial infection or may be a symptom of an allergic reaction. If hives are accompanied by other serious symptoms such as difficulty breathing, it can be a sign of a serious allergic reaction.
Chronic hives occur almost daily and last for more than 6 weeks. They may be caused by an infection, skin irritation, a problem with the immune system, or other medical conditions. It is common that chronic hives have no known cause.
“Roughly 1 in 5 people will experience hives at some point in their lives, and over 3 million people in the U.S. will experience chronic hives,” said Kenneth Mendez, president and CEO of AAFA. “Urticaria Day provides an opportunity to promote understanding of the condition and its impact. The raised bumps (welts or wheals) of hives often cause persistent itching. This can impact sleep and other activities. People with chronic hives may find relief from one of several available treatment options. AAFA wants people with urticaria to be aware of treatment options, and for those options to be accessible and affordable.”
Two common types of chronic hives are:
- Chronic spontaneous urticaria (CSU): hives that occur for no known reason
- Chronic inducible urticaria (CIndU): hives triggered by known physical factors such as cold, heat, pressure, friction, vibrations, exercising, sweating, and UV sunlight (rare)
Treatment options for hives include over-the-counter or prescription antihistamines. For chronic hives that don’t resolve with antihistamines, there are other effective treatment options. People with hives should talk with their doctor about the best treatment options for them.
Chronic hives can severely impact daily life, sleep, and mental well-being. Despite available treatments, many people continue to struggle with persistent symptoms, especially chronic itch and unpredictable flare-ups.
“We hear from people every day about how urticaria disrupts their lives – everything from being able to work or go to school to taking showers and baths,” said Kristen Willard, executive director of We CU and a CSU patient in remission. “Our collaboration on UDay is about giving voice to those challenges and working toward a future where urticaria is better understood, better researched, and better treated.”
The partnership among the three organizations also reflects the overlap among patient populations. Many individuals living with urticaria also manage asthma, allergies, mast cell disease, or other immune-related conditions.
“We know that for many patients, urticaria is part of a bigger picture of immune system dysfunction,” said Jessica Fraser, executive director of TMS. “Recognizing UDay as a community helps ensure that no one is left behind, and that together we can advocate for expanded research, clinical awareness, and comprehensive care.”
Hives can range from being a mild irritation to being a sign of a potentially life-threatening serious allergic reaction or other medical conditions. Chronic hives can lead to social isolation and feelings of despair.
Mild to intense itching is a common symptom of hives. Other symptoms include burning and stinging.
Call your doctor if:
- Your hives are making you uncomfortable or interfering with your life
- You have never experienced hives before
Go to the emergency room or call 911 if:
- Hives are severe and cover a large area of your body
- There are other concerning symptoms such as trouble breathing
Through education, advocacy, research, and awareness activities, AAFA, We CU, and TMS are committed to advancing the conversation on urticaria and improving the lives of those affected.
