Chronic hives (chronic urticaria) are red, itchy skin welts that last more than six weeks. Many people have these welts every day for a year or longer. People with certain autoimmune diseases are more prone to chronic hives.
In acute urticaria hives are present for less than 6 weeks of duration. Chronic Spontaneous Urticaria (CSU) is defined as hives that are present for at least or greater than 6 weeks and for the most days of the week. Physical urticaria is present only when certain physical stimuli are applied.

Hives on brown skin Hives — also called urticaria (ur-tih-KAR-e-uh) — is a skin reaction that causes itchy welts. Chronic hives are welts that last for more than six weeks and return often over months or years. Often, the cause of chronic hives isn't clear.
Acute urticaria is caused frequently by IgE-mediated allergic reactions to foods or by acute infections, usually viral respiratory tract infections. 'Papular urticaria' occurs more often in children than in adults, and is due usually to insect bites.
Official answer. The main difference between hives and a rash is that hives are a particular type of rash, characterized by swollen, pale-red or skin-colored bumps on the skin that appear and disappear quickly, and tend to “blanch” (which means turn white) when pressed. Hives are also known as urticaria.
Acute episodes of urticaria last for six weeks or less. Acute urticaria can be due to infections foods, medications, insect stings, blood transfusions and infections. The most common cause of hives is infections. Foods such as eggs, nuts and shellfish are common causes of urticaria.
Chronic urticaria (CU) is defined by recurrent episodes occurring at least twice a week for 6 weeks. [3] Females are more commonly affected than males.
Autoimmunity is thought to be one of the most frequent causes of chronic urticaria. Various autoimmune or endocrine diseases have been associated with urticaria, including systemic lupus erythematosus, cryoglobulinemia, juvenile rheumatoid arthritis, and autoimmune thyroid disease (eg, Graves disease).
Acute urticaria is diagnosed in people with a short history of weals that last less than 24 hours, with or without angioedema. A thorough physical examination should be undertaken to look for underlying causes.
